OUR MISSION AND OUR TECHNOLOGY

The energy storage market is forecast to be worth trillions by 
2050. Invinity is in a leading position to capitalise on the demand 
for  long  duration  energy  storage  driven  by  this  tremendous 
growth. 

OUR MISSION

The world is now responding to the climate emergency. Global 
energy systems are rapidly decarbonising by shifting to low 
carbon  but  fundamentally  intermittent  renewable  energy 
sources.  Energy  storage  is  the  key  to  the  next  phase  of  the 
energy  transition.  Our  vanadium  flow  batteries  unlock  low-
cost,  low-carbon  renewable  energy  on  demand,  delivering 
clean energy for generations to come. 

Invinity was created to address the large and rapidly growing 
global market for energy storage solutions. The Company’s safe, 
reliable,  durable  and  economical  VFB  technology  addresses 
many of the limitations of incumbent battery technologies such 
as  lithium-ion.  Invinity’s  batteries  are  fully  recyclable,  do  not 
catch  fire  and  do  not  contain  rare  earth  or  ‘conflict  materials’ 
such as cobalt. The Company holds itself to high standards of 
sustainability and looks to make a significant contribution as part 
of the ‘Just Transition’ to net zero.

OUR TECHNOLOGY

Invinity’s VS3 flow battery technology has been designed to 
operate in high-throughput, heavy cycling applications. This 
capability defines “utility-grade” energy storage and gives 
our  customers  the  operational  freedom  to  maximise  their 
return on investment. It also makes the VS3 particularly well 
suited for storing and dispatching energy on demand directly 
from  renewable  generation  or  managing  constrained  grid 
connections  on  a  centralised  basis  to  deliver  low-carbon 
electricity to the grid over decades of service. 

Our product has 4 key attributes that are highly advantageous 
for the global stationary energy storage market. They are:

1. Safe  – the VS3 has no fire risk (unlike lithium batteries) as 
the electrolyte is an aqueous (water-based) solution, meaning 
VS3s may be safely deployed anywhere.

2. Durable – the VS3 has unlimited cycling capability and does 
not degrade, allowing it to be cycled multiple times per day 
over more than 20 years of continuous operation.

3. Economical  –  the  VS3  provides  a  consistently  low  cost  per 
MWh over its lifetime on a Levelised Cost of Storage (LCOS) basis.

4. Proven – the VS3 is already serving a variety of customers in 
a range of applications around the world.

With  over  33  MWh  of  VFBs  either  contracted  or  deployed 
globally,  Invinity  has  a  strong  commercial  foundation  that 
continues to  grow, supported by the global transition to net 
zero  and  the  need  to  install  stationary  energy  storage  to 
achieve global renewable energy targets.

In 2021, Invinity made the transition from a company working 
to  refine  its  product  offering  to  a  company  shipping  a 
standardised, modular product to customers across the world. 
Although this transition took longer than expected due to the 
continued impacts of the COVID pandemic in both 2020 and 
2021, the Company is now in a strong position to utilise these 
successful commercial VS3 product deployments as reference 
sites, accelerating commercial traction for Invinity’s products.

DEVELOPING THE WORLD’S LARGEST  
SOLAR-POWERED FLOW BATTERY  
WITH EDF RENEWABLES AND THE  
UK GOVERNMENT 

Invinity’s latest commercial flow battery opportunity is the 40 
MWh Vanadium Flow Battery Longer-duration Energy Asset 
Demonstrator  (VFB  LEAD)  project  announced  in  February 
2022. Receiving support from the UK Government, this very 
large and exciting project will once again see Invinity working 
alongside  EDF  following  the  successful  deployment  of  the 
UK’s current largest vanadium flow battery, a 5 MWh system, 
at the Energy Superhub Oxford (ESO). 

VFB LEAD aims to develop and deploy one of the UK’s largest 
co-located solar + storage projects, featuring a 40 MWh VFB 
hybridised with a lithium-ion battery and connected to a utility-
scale solar PV array. Invinity, alongside Pivot Power (part of EDF 
Renewables) and EDF R&D UK, are amongst the five winners 
of  Phase  1  (Project  development  stage)  in  Stream  1  (proven 
technologies) of the UK Government’s Longer Duration Energy 
Storage  (LODES)  competition.  Run  by  the  Department  for 
Business, Energy and Industrial Strategy (BEIS), the competition 
aims  to  accelerate  the  commercialisation  of  longer-duration 
energy storage through large-scale demonstration projects. 

At  least  three  of  the  five  Phase  1  winners  will  be  chosen  to 
proceed to Phase 2 (Construction stage). If successfully chosen 
for Phase 2 and once operational, Invinity’s VFB LEAD project 
could be the largest of its type worldwide. This competition is 
part  of  the  £1bn  BEIS  “Net  Zero  Innovation  Portfolio”  (NZIP), 

which is being managed by the UK’s “Science and Innovation for 
Climate and Energy Directorate” (SICE).

Winning Phase 1: A case study in multi-partner, cross-
functional collaboration across the energy industry
Invinity has built long-term relationships with key government 
departments in core target markets. Within the UK, Invinity’s 
business  development  team  has  maintained  an  ongoing 
dialogue  with  government  departments  and  agencies,  most 
notably BEIS and Innovate UK. Invinity was therefore prepared 
for the release of a specifically non-lithium, non-pumped hydro, 
longer-duration  energy  storage  grant  opportunity  in  March 
2021 when the LODES competition was formally launched by 
BEIS. Invinity was able to apply immediately. 

Invinity’s  London-based  business  development  team,  part 
of  the  Company’s  Commercial  division,  led  the  response. 
The  business  development  team  is  tasked  with  identifying 
new  market  opportunities  for  the  Company’s  products  as 
well  as  qualifying  and  responding  to  relevant  grant  funding 
opportunities. They work closely with prospective customers 
to optimise their business cases for maximum return from their 
investment.  This  insight  into  how  customers  look  to  operate 
battery  systems  provides  important  feedback  for  Invinity’s 
Product Development, Solutions Engineering and R&D teams 
to assist with their strategic decision making.

The VFB LEAD application process required Invinity’s Commercial, 
Product  Development,  Solutions  Engineering,  Finance  and 
Executive teams to coordinate closely. Invinity, encouraged by 
the interest from long-standing partners to be part of the project 
consortium, chose Pivot Power (part of EDF Renewables), EDF 
R&D and Imperial College London. A comprehensive application 
was submitted within the timeframe that turned out to be one of 
the highest scoring applications received.

Leading a winning consortium towards Phase 2 delivery
EDF and Invinity are working through 2022 on Phase 1 of the 
competition,  the  “ready  to  build”  phase.  Down  selection  for 
the  Phase  2  winners  is  expected  by  BEIS  in  Q2  2023  and  if 
successful, the project will progress to the construction phase. 
Once  commissioned,  the  project  is  forecast  to  avoid  up  to 
27,400 tonnes of CO2 per year.

Prior  to  the  official  announcement  on  23  February  2022,  the 
consortium, led by Invinity, worked to conclude the grant funding 
agreement with BEIS and the formal collaboration agreements 
between the consortium partners. 

In the official announcement made by BEIS at the 7th Energy 
Storage Summit in London, Energy and Climate Change Minister 
Greg Hands MP said:

“Driving forward energy 
storage technologies will be 
vital in our transition towards 
cheap, clean and secure 
renewable energy.

Working  with  BEIS  has  also  led  to  numerous  follow-up 
opportunities  for  Invinity,  including  a  roundtable  on  longer 
duration energy storage with Greg Hands MP alongside other 
industry leaders and an invitation to give evidence to the House 
of Lords Economic Affairs Committee enquiry into the UK Energy 
Supply and Investment on the benefits of Invinity’s technology 
for the UK’s energy future. 

technologies  continue 

As  a  new  energy  storage  asset  class,  longer-duration,  high-
throughput,  non-lithium 
to  gain 
prominence  in  global  markets.  Invinity’s  ability  to  capitalise 
on  opportunities  such  as  the  LODES  competition  is  a  key 
competitive  advantage.  This  proven  track  record  of  working 
with government agencies around the world – BEIS in the UK, 
ARENA  in  Australia  and  the  CEC  in  the  USA  –  underlines  the 
commitment  of  the  Invinity  team  to  accelerating  the  energy 
transition by deploying safe, reliable and durable VFBs at scale 
as a vital part of the net zero energy system of the future. 

Matt Harper addressing the House of Lords Economic Affairs 
Committee on UK Energy Security and LDES – May 2022

It will allow us to extract the full benefit from 
our home-grown renewable energy sources, 
drive down costs and end our reliance on 
volatile and expensive fossil fuels. Through 
this competition we are making sure the 
country’s most innovative scientists and 
thinkers have our backing to make this 
ambition a reality.”

MOTIVATING REAL CHANGE
Chairman’s Report 

The past 12 months in energy have illustrated that only a 
crisis  can  motivate  real  change.  Much  of  the  world  now 
recognises  that  the  clean  energy  transition  must  be  a 
global priority. Unlocking low-cost, low-carbon electricity 
through  the  widespread  adoption  of  safe  and  reliable 
battery storage has therefore become an urgent necessity. 

It is widely recognised that the electricity grids of the future will 
require storage to balance out the inherent volatility of solar and 
wind generation. According to Bloomberg New Energy Finance 
(BNEF), the global energy storage market is expected to grow 
eight-fold from 22 GWh installed today to up to 178 GWh installed 
annually  by  the  end  of  the  decade.  Our  growing  pipeline  of 
commercial opportunities confirms that Invinity’s vanadium flow 
batteries will play an important part in this market, dispatching 
renewable energy into the ‘missing hours’ of wind and solar.

Encouraged by this uptick in demand, I am pleased to note we 
have  secured  major  cornerstone  projects  in  each  of  our  core 
markets:  the  UK,  North  America  and  Australia.  Our  largest 
flow battery to date at the Energy Superhub Oxford (ESO) has 
become a key reference site for the Company. Despite global 
supply chain and logistics headwinds, throughout 2021 and early 
2022 we delivered approximately 250 of our battery modules 
with a combined capacity of more than 8 MWh to customers 
across  the  world.  This  achievement  underlines  how  Invinity 
stands apart from others in the flow battery industry. We will 
continue to build on this strong foundation in the years to come. 

Our 5 MWh flow battery, an integral part of the ESO project, was 
energised  in  2021  alongside  a  lithium-ion  battery.  This  hybrid 
system  is  currently  the  UK’s  largest  transmission-connected 
battery. To deliver this project, Invinity worked alongside Pivot 
Power  (part  of  EDF  Renewables),  Habitat  Energy,  Siemens 
Gamesa  and  other  leading  industry  players  to  provide  a 
model for urban decarbonisation. I was delighted to note that, 
working  again  with  Pivot  Power,  Invinity  received  funding  in 
February of this year from the Longer Duration Energy Storage 
Demonstration  (LODES)  competition  toward  developing  a 
project almost ten times the size of ESO. Building relationships 
such  as  this  with  major  players  across  the  industry  is  core  to 
our corporate strategy and is intended to result in securing ever 
larger orders for our products and support our efforts to reduce 
our operating costs still further.

Another key highlight of the year was the commencement of a 
Joint Development and Commercialisation Agreement (JDCA) 
with  Gamesa  Electric,  part  of  Siemens  Gamesa  Renewable 
Energy  (SGRE),  in  May  2021.  This  exciting  partnership  will 
support  the  development  and  commercialisation  of  a  new 
Invinity battery product specifically targeting grid-scale projects 
an order of magnitude larger than the project sizes the Company 
currently focuses on.

Looking inward, Invinity has assembled what the Board believes 
to  be  a  market-leading  team  which  focuses  on  winning  new 
contracts, deploying our product and continuing to develop our 
leading-edge  technology,  whilst  improving  performance  and 
reducing costs yet further. In a year which saw the challenges 
of  COVID  and  supply  chain  disruption  continue  to  impact  on 
our  plans,  I  would  like  to  take  this  opportunity  to  thank  the 
entire  Invinity  team  for  their  efforts  and  successes  in  2021. 
The dedication and diligence of our staff has been exemplary, 
especially during the long ISO audit process which resulted in 
the recent awarding of three major certifications concurrently. 
Finally, I would particularly like to thank all my Board colleagues 
for  their  support  and  assistance  over  the  year.  Our  latest 
addition to the Board, Kristina Peterson, is already making an 
impact with her knowledge of the wider renewable industry and 
I am grateful to Rajat Kohli who now leads our newly formed 
Environmental, Social & Governance (ESG) Committee.

“The widespread adoption 
of safe and reliable battery 
storage has therefore become 
an urgent necessity. ” 

In  summary,  2021  saw  Invinity  continue  to  close  sales  for  our 
products, begin to recognise meaningful revenue as a result of 
contract deliveries and raise funds which enable us to scale and 
grow in line with expanding global demand for energy storage. 
2022 has already seen Invinity making further progress on both 
sales and delivery. I look forward to the team converting more 
of our pipeline leads into sales contracts throughout 2022 and 
continuing to generate long-term value for shareholders.
Energy storage technologies such as vanadium flow batteries 
hold the key to the next stage of the global energy transition. 
I  continue  to  be  extremely  optimistic  in  relation  to  Invinity’s 
position within one of the fastest growing areas in the global 
energy market and look forward to further success as we deliver 
on this opportunity in 2022 and beyond.

Chief Executive Officer’s Report 

2021  was  a  year  of  tremendous  accomplishments,  some 
challenging  setbacks,  but  overall  significant  progress  for  
Invinity.  I  will  report  to  you  in  three  areas:  1)  the  macro 
environment, 2) Invinity’s products, and 3) our strategic growth.

The Macro Environment
The  entire  world  is  electrifying.  The  reasons  are  many:  to 
reduce carbon emissions, improve air quality and more recently, 
to  achieve  national  energy  security.  This  architectonic  shift 
toward electrification won’t occur smoothly or consistently, but 
the eventual outcome is not in doubt.

During 2021, the market for battery energy storage continued 
a year-long shift from potential to actual. The view that battery 
energy storage will play an essential part in the energy transition 
has become accepted at every level of the energy industry and 
especially among government leaders. Our Chief Commercial 
Officer,  Matt  Harper,  recently  addressed  the  House  of  Lords 
Economic Affairs Committee on the roles battery energy storage 
will play in the years to come. Those roles are: 1) compensating 
for  shifts  in  demand  and  2)  dispatching  low-carbon  energy 
over  hours,  not  minutes.  Both  needs  are  becoming  more 
acute as intermittent renewables sources increasingly form the 
foundation of the world’s electricity system.

But  which  battery  technology  to  use?  Lithium,  the  most 
common,  has  achieved  that  position  without  a  viable 
alternative. Lithium may be ahead today, but it has not won the 
race. We are already delivering projects at a scale equivalent 
to the largest lithium-ion battery deployments achieved just a 
few years ago. The BEIS funded 40 MWh LODES project we 
are pursuing with Pivot Power/EDF is just one example.

There are many concerns about lithium batteries; they catch 
fire and wear out, and when they do, they leave a legacy of 
difficult-to-recycle  toxic  waste.  Their  components  –  lithium 
and nickel in particular – are dramatically increasing in price. 
Cobalt  is  sourced  from  areas  of  conflict.  Recent  industry 
analyses have concluded that there won’t be enough lithium 
produced to come close to meeting the world’s ambitions for 
the electrification of mobility, of cars and transport, much less 
supply the demand for stationary storage at massive scale to 
support the transition to renewable energy. In 10 years, we’re 
going to look back and wonder why we put large quantities 
of  perfectly  good  lithium,  essential  for  electrifying  mobility 
and portable uses, into boxes in a field to deteriorate. 

For these reasons, the California Energy Commission (CEC) 
–  charged  with  setting  energy  policy  for  the  world’s  fifth-
largest economy – recently conducted a day-long workshop 
on long-duration non-lithium storage. I was invited to speak 
and was proud to not only show photographs of our products 
in  operation  but  note  that  I  was  the  only  presenter  with  a 
working product in the field. This brings us to the core of our 
business, supplying what we believe to be the world’s most 
advanced vanadium flow battery. 

Larry Zulch

Invinity’s Products
Invinity  is  fundamentally  a  product  company.  Our  current 
product,  the  VS3,  has  been  installed  and  is  operating  at  the 
Energy  Superhub  Oxford,  Scottish  Water  Perth,  EMEC  and 
soon in projects in California, at Chappice Lake in Canada and 
Yadlamalka in South Australia.

Our  product  design  strategy  is  three  pronged:  first  and 
foremost, our batteries must be safe and reliable. Second, they 
must perform; they must efficiently store and discharge energy 
on  command  so  that  a  battery  owner  can  depend  on  their 
reliability. Third, they must be long-lived, a characteristic that is 
core to our value proposition.

But  these  are  just  table  stakes;  they  are  what  our  customers 
expect.  The  real  driver  for  everything  we  do  and  why  our 
customers buy our products comes down to economics. Our 
success will derive from continuing to communicate our superior 
capabilities  in  economic  terms,  which  often  translates  into  a 
lower cost per unit of energy stored and discharged during the 
life of the battery.

An important component of this calculation is the system cost, 
a  key  focus  for  Invinity  and  an  area  the  Company  continues 
to improve upon. We’re working hard to reduce costs across 
all  areas  for  our  VS3.  In  2021  we  had  some  backward  steps, 
including  supply  chain  disruptions  and  skyrocketing  shipping 
charges. But these challenges have driven us to improve, and I’m 
delighted to report that despite a trend towards higher overall 
costs,  we  increased  the  efficiency  of  building  our  cellstack, 
reduced manufacturing costs, and qualified better performing 
materials  across  our  supply  chain.  These  efforts  support  our 
work on the LODES competition from the UK Government, for 
which cost reduction is a key parameter.

A  significant  step  change  in  our  customer-facing  economic 
proposition  is  underway  through  our  work  with  Siemens 
Gamesa Renewable Energy (SGRE) and their subsidiary Gamesa 
Electric. We are co-developing a grid-scale flow battery that I 
firmly believe will be head and shoulders above any other flow 
battery ever developed. The development process is complex 
and requires everything we know and have learned as one of 
the  most  experienced  teams  in  vanadium  flow  batteries.  Our 
joint activities are progressing well and we’re looking forward 
to providing product details once we reach the stage where it is 
appropriate to do so.

Annual Report and Financial Statements 2021UK  /  US  /  CANADA  /  AUSTRALIAINTRODUCTIONSTRATEGIC REPORTGOVERNANCEFINANCIAL STATEMENTSInvinity Energy Systems plcStrategic Growth
We are continuing our focus on three core markets: UK, North 
America, and Australia, and expanding our engagement with 
them  as  I  discuss  below.  Our  strategy  in  other  important 
global markets requires finding a substantial partner who can 
represent us and our products by providing sales, installation, 
and service support. A template for this strategy is in South 
Korea  where  Hyosung  has  become  our  distributor.  I  can’t 
imagine a better partner than Hyosung in South Korea with 
their  impressive  infrastructure  and  capabilities  in  what  is  a 
very exciting market for flow batteries.

The United States is an area with much potential for Invinity in 
two areas: corporate development and market development, 
both  aided  by  our  recent  announcement  that  we  have 
engaged EAS Partners to advance our US presence. EAS’s 
initial focus is on increasing the level of US investor activity in 
Invinity shares. We’ve brought on Matt Walz as Vice President 
of  Business  Development,  whose  extensive  experience  in 
energy  businesses  from  AES  Corporation  to  Duke  Energy 
brings  considerable  depth  to  the  US  Invinity  team.  Matt’s 
work  on  our  US  market  development  includes  building  on 
our relationship with the CEC and pursuing US government 
support  for  energy  storage  initiatives  that  were  part  of 
President Biden’s infrastructure bill. 

In the UK, we are now admitted to trading on the Aquis Stock 
Exchange  (AQSE)  which  has  increased  liquidity  in  Invinity’s 
shares  and  facilitated  trading  in  the  warrants  that  were 
created as part of our fundraise in late 2021. We’ve hired Peter 
Strassheim  as  director  of  sales  in  the  UK  and  EU.  Peter  will 
enhance  our  commercial  capabilities  in  the  UK,  building  on 
work we’ve done with BEIS including the LODES competition, 
jointly  with  Pivot  Power,  to  help  advance  the  commercial 
viability of non-lithium energy storage. We’re planning to soon 
enhance  our  senior  executive  presence  in  the  UK,  further 
underscoring our commitment to our home market.

In Australia, the Yadlamalka project site is in the process of 
being successfully relocated. We’re eager to begin delivery 
of the products we’ve built for it. We’re pursuing even larger 
projects  with  ARENA  under  the  leadership  of  Michael  Rutt, 
our recently hired Regional Director of Australia Pacific based 
in Melbourne. The Australians, blessed with ample sunshine 
and  wind,  are  acutely  aware  of  the  need  to  augment  their 
renewable power with energy storage.

Our activities in the three focus regions are one of three major 
areas  where  we  are  deploying  the  funds  we  raised  late  in 
2021. The other two are advancing the previously discussed 
development of a grid-scale battery with SGRE and Gamesa 
Electric  (which  I  have  discussed  earlier  in  this  report)  and 
delivering  on  the  project  commitments  we’ve  signed  and 
announced.  Our  work  in  these  three  areas  significantly 
advances our mission to make our vanadium flow batteries a 
commercially viable alternative to lithium storage.

Delivering  on  our  announced  project  commitments,  the 
third area, has required significant effort and resources as 
we  have  learned  to  successfully  navigate  a  world  much 
different  than  it  was  just  a  few  years  ago.  Every  business 
with a global supply chain, especially those manufacturing 
components in China, as we do, has had to find ways to turn 
obstacles into opportunities.

In  recognition  of  our  growing  sales  backlog,  which  we  aim 
to  deliver  and  recognise  as  revenue  in  2022  and  beyond, 
we have taken the strategic decision to expand our capacity 
by  establishing  a  manufacturing  relationship  with  long-time 
Invinity  supporter  Suzhou  Baojia  New  Energy  Technology 
Co. (Baojia). With over 1,000 employees and facilities of over 
180,000 square meters located across Asia, Baojia will be an 
important partner for Invinity at this exciting stage of growth 
and can help us to rapidly achieve greater scale in a rapidly 
expanding  market.  Our  current  manufacturing  partner,  BCI, 
an  early  investor  in  Avalon,  one  of  Invinity’s  predecessors, 
remains a supportive shareholder as they look to focus their 
manufacturing capabilities within the US market. 

Our  attention  to  delivery  means  more  than  smoothing  our 
global supply chain and upgrading manufacturing; we must 
source vanadium electrolyte from partners around the world 
and assist the developers of projects that will be incorporating 
our batteries to overcome obstacles. We have deepened our 
relationships with global vanadium and vanadium electrolyte 
suppliers  to  reduce  our  exposure  to  commodity  pricing  as 
they and we look to much greater quantities in 2022 and yet 
greater volume in 2023. Our very capable UK-based solutions 
engineering  team  has  been  engaging  with  developers  of 
projects  that  plan  to  use  our  batteries  around  the  world, 
providing crucial assistance as the developers engage with 
innovative energy transition opportunities.

“Battery energy storage 
will play an essential part in 
the energy transition and has 
become accepted at every 
level of the energy industry.” 

Looking to the Future
Although  undeniably  challenging,  2021  saw  the  Company 
convert  record  order-flow  in  2020  into  meaningful  revenue 
for the first time in its history. In my 2020 report, I noted that 
2021 would be the year that Invinity would demonstrate its 
capabilities on a wider stage. Despite significant challenges, 
I  believe  we  have  made  important  progress  on  this  front. 
Invinity ended 2021 in the best position it has ever been in 
terms  of  products,  finances,  market  opportunity,  and  our 
ability to execute. Since then, we’ve made substantial further 
progress despite delays in announcing product deliveries and, 
not  entirely  unrelated,  delayed  announcements  of  product 
sales.  With  a  macro  environment  extremely  favourable  for 
non-lithium  storage,  an  ability  to  execute  increasing  daily, 
and  a  future  vision  that  is  compelling,  I  not  only  retain  my 
optimism toward our business, I grow increasingly confident 
in  our  ability  to  realise  our  potential.  Thank  you  for  your 
support of Invinity. We continue to work with everything we 
have to merit your confidence.

Chief Commercial Officer’s Report 

Vision
Invinity  was  founded  on  the  belief  that  success  lies  in 
commercial opportunities where our products deliver more to 
our customers – more revenue, more cycles, more profits. 

In  2021  the  global  energy  storage  market  started  to  recognise 
that the grid of the future will need a new asset class – higher-
throughput, 
longer-duration,  non-lithium  storage  solutions. 
Lithium batteries have been successful delivering minutes to hours 
of power at irregular intervals, but to reliably deliver low-cost, low-
carbon energy, renewables need support from energy storage 
multiple times per day and for hours at a time. This is where we 
believe Invinity’s vanadium flow batteries are without equal.

This recognition is driving growth in our sales pipeline over the 
last six months. We track our sales pipeline in stages: Qualified, 
Advanced,  Base  and  Closed.  Qualified  opportunities  have  a 
solid  revenue  case,  well-established  project  and  site  details, 
and  a  reason  why  Invinity’s  batteries  are  the  best  possible 
solution. Advanced opportunities are those where Invinity has 
been  selected  as  the  battery  supplier  and  site  engineering 
and planning are well underway. The Base category contains 
projects upon which we base our business: prices have been 
agreed, contracts are in process, and we have reserved working 
capital and manufacturing production slots to ensure we deliver 
on schedule. Closed opportunities are those which we are in the 
process of delivering or have already delivered.

The  8.4  MWh  project  with  Elemental  Energy  announced  in 
February 2022 increased Closed and decreased Base in 2022 
in the table above. Advanced grew mainly from the 40 MWh 
project we are developing with our partners at Pivot Power and 
EDF Renewables for Phase 2 of the UK’s LODES competition. 
Qualified opportunities grew because of the increasing number 
of high-quality opportunities in development. 

We focus our sales efforts by segmenting opportunities among 
our three core markets – the UK, North America and Australia 
–  and  pursue  projects  outside  these  markets  only  when  we 
have a strong partner such as Hyosung in South Korea. Since 
early 2022 we have strengthened our sales team: Michael Rutt 
joined our team as Regional Director in Australia, Jan Petrenko 
as  Regional  Manager  for  North  America,  and  most  recently 
Peter Strassheim as Regional Director for the UK and Europe. 

We  focus  on  customer  categories  most  receptive  to  our 
products’ inherent advantages: behind-the-meter commercial 
or industrial customers and front-of-meter project owners or

operators. Helping drive the focus and relationships needed 
for  success  in  these  segments  is  Matt  Walz,  who  recently 
joined  Invinity  as  Vice  President  of  Business  Development, 
based in the US.

Progress in 2021
2021 was a year where renewable energy and energy storage 
made  unprecedented  progress  in  the  face  of  extraordinary 
challenges. Solar and wind power are delivering results: for 
example, for a few hours in early May 2022 California powered 
its electric grid with 100% renewable generation for the first 
time  ever.  2021  also  saw  significant  headwinds  emerging. 
Prices for everything from solar PV racking to transformers 
were up by 70% or more and shortages of components and 
personnel severely impacted the ability to get projects built 
and  operational.  Despite  these  challenges,  the  unwavering 
support of our employees, customers and suppliers allowed 
Invinity  to  deliver  ground-breaking  projects  at  the  Energy 
Superhub Oxford and to Scottish Water, yielding significant 
revenue for the first time. 

The  past  year  also  saw  both  progress  and  challenges  to 
lithium  battery  projects.  Some  of  the  largest  battery  arrays 
ever  conceived  have  come  online,  yet  developers  struggle 
with  lithium  battery  price  increases  of  up  to  50%  driven  by 
supply  chain  disruptions  and  increasing  demand.  Safety 
has  come  to  the  forefront  following  lithium  battery  fires  in 
Australia,  the  US  and  the  UK,  triggering  tougher  standards 
(and increased costs) for fire detection, fire suppression and 
emergency  responder  access.  Finally,  the  operational  limits 
of very large lithium arrays are becoming better understood, 
limiting their revenue potential. 

Recognition  of  these  challenges  is  pushing  developers  to 
seek  alternatives  as  reflected  in  the  considerable  growth 
in  the  Qualified  section  of  Invinity’s  sales  pipeline.  Similarly, 
government  agencies  like  the  CEC,  BEIS  and  ARENA  and 
independent  bodies  like  Breakthrough  Energy  are  funding 
broad  programmes,  such  as  LODES  in  the  UK,  to  spur  the 
growth of non-lithium long-duration storage. 

Despite these generally supportive market conditions, individual 
deals tend to focus on three factors: value, cost and proof. The 
value  delivered  by  our  product  must  be  well  established,  the 
cost of our product must align with the market, and the proof 
that our products perform must be unassailable. 

1313

Annual Report and Financial Statements 2021UK  /  US  /  CANADA  /  AUSTRALIAINTRODUCTIONSTRATEGIC REPORTGOVERNANCEFINANCIAL STATEMENTSInvinity Energy Systems plc 
 
The  value  of  longer-duration,  higher-throughput  batteries  is 
qualitatively well established, but the market and financial structures 
to fully exploit their advantages remain underdeveloped. Multiple 
revenue streams in a single project – “stacking” energy trading 
and frequency regulation, for instance – don’t fully compensate 
for markets designed for hydrocarbon-fuelled peaking plants or 
short-duration lithium batteries. Fortunately, we see change on 
the horizon.

Cost  reduction  also  comes  from  refining  our  product  design, 
and part of our Phase 1 LODES funding is allocated to reducing 
the cost of our current product. Further improvement will come 
through our development programme with Siemens Gamesa to 
develop and commercialise an Invinity VFB that delivers lower 
costs than our competitors at the gigawatt-hour scale of today’s 
largest energy storage projects. We have made good progress 
on this programme and expect to release details of that product 
in the first half of 2023.

The initial  cost of purchasing one of Invinity’s VFBs is typically 
more than an equivalent lithium battery. However, customers tell 
us that the additional safety and siting costs required for lithium 
often bring us to cost parity, especially on projects under two 
megawatt-hours. We focus on those customers that need high 
throughput storage. An example is our project at EMEC, where 
four charge and discharge cycles per day mean our batteries 
deliver technically and economically superior performance. 

Beyond 2022: Increasing Value
The  groundwork  for  regulatory  changes  that  will  massively 
increase Invinity’s value to our customers is being laid through 
pathfinder projects from government agencies like BEIS, the CEC 
and ARENA. Our projects with Pivot Power, Elemental Energy 
and  Yadlamalka  Energy  will  be  at  the  forefront  of  informing 
future policies.

Policymakers value independent analysis such as Aurora Energy 
Research’s February 2022 report titled “Long duration electricity 
storage in GB” that noted that the UK grid would need up to 
24 GW of long duration storage by 2035, saving UK ratepayers 
£1.13bn per year while decreasing UK annual CO2 emissions by 10 
million tons. Amongst the range of storage solutions analysed, 
VFBs  were  highlighted  favourably  on  factors  such  as  lifetime 
cost and durability.

We have been encouraged by policymakers seeking Invinity’s 
input on delivering a net zero grid while creating employment 
opportunities  and  improving  domestic  economies.  Invinity 
engaged  in  a  CEC  workshop  on  Advancing  Non-Lithium-
Ion  Long  Duration  Energy  Storage  Technologies,  presented 
evidence to the House of Lords’ Economic Affairs Committee 
on UK energy supply and investment, participated in an industry 
roundtable with UK Energy Minister the Rt Hon Greg Hands MP, 
hosted  the  Scottish  Cabinet  Secretary  for  Net  Zero,  Michael 
Matheson  MSP  at  our  facility  in  Bathgate,  and  hosted  British 
Consul General Thomas Codrington at our facility in Vancouver. 
In each case, our message was very well received.

Aligning and Accelerating
Despite  delays,  2021  saw  Invinity  start  to  generate  significant 
revenue by delivering major contracts, secure important follow-
on  opportunities  and  grow  the  pipeline  of  qualified  deals. 
Invinity’s commercial position, stronger than ever, will become 
even more robust as we establish Value, Cost and Proof for our 
customers.  Taken  together,  this  combination  of  position  and 
traction give us tremendous confidence in our future commercial 
prospects and makes us excited for the role that Invinity and our 
VFBs have to play as a necessary part of our future net zero grid.

Matt Harper
Chief Commercial Officer

The final factor is proof that our products perform. Historically, 
dozens of energy storage companies have attempted to deliver 
novel technologies to market, only to fail to navigate the chasm 
between the lab bench and a customer’s site. Our customers 
know  this  and  rightly  insist  on  seeing  proven  operation 
in  comparable  projects  before  committing.  Supply  chain 
challenges in 2021 meant key projects in California, Australia and 
the UK were delayed, stalling our ability to demonstrate that our 
products deliver. But with our projects at ESO, Scottish Water 
and EMEC now delivered and major projects in the US, Canada 
and Australia not far behind, proof is at hand. 

Early 2022: Enhancing Proof
February 2022 was a remarkable month. We announced an 8.4 
MWh  DC-coupled  solar-plus-storage  project,  North  America’s 
largest flow battery, at Chappice Lake, Alberta, Canada alongside 
Elemental Energy, a developer, owner and operator of over 800 
MW of wind and solar projects. This project is nearly identical to 
our project at Yadlamalka, South Australia, demonstrating the 
repeatability of our business model.

Later  in  February,  we  announced  £0.7m  of  Phase  1  funding 
from BEIS as part of their LODES programme. Our joint entry 
with ESO partner Pivot Power underscores the strength of our 
relationship. Phase 2, if selected – and with five companies vying 
for at least three spots, our chances are good – will see us deliver 
the UK’s largest flow battery, a 40 MWh Invinity VFB, co-located 
with lithium batteries and solar generation to deliver low-carbon 
power on demand. 

Finally, during April we announced a relationship with Hyosung, 
one  of  Korea’s  largest  energy  storage  systems  integrators.  In 
2018  Korea  was  the  single  largest  global  market  for  storage, 
but the large number of lithium battery fires there has curtailed 
growth.  Hyosung  extensively  tested  Invinity’s  batteries  and 
sees tremendous opportunities in deploying them in Korea and 
beyond.

Next in 2022: Reducing Cost
Our  growing  production  volumes  will  deliver  another  benefit: 
lower  costs.  The  combined  16.4  MWh  we  will  deliver  to 
Yadlamalka Energy and Elemental Energy more than doubles 
Invinity’s  total  production  to  date.  We  will  use  the  expertise 
gained in doing so to increase quality and reduce manufacturing 
costs at a faster rate than lithium batteries which have already 
benefited from decades of high-volume manufacturing.

Chief Financial Officer’s Report 

Financial Highlights

 Revenue for the year of £3.2m, a 690% increase vs 2020;
 Year-end closed sales backlog of £13.8m;

   Year-end inventory of £9.9m, including prepaid inventory;
   Year-end cash of £26.4m (2020: £22.0m);
   May 2022 month-end cash of £18.3m;
   The Group remains debt free, excluding leases.

Operational
The  four  significant  operational  and  financial  highlights  that 
characterised 2021 for the Group were: 

1.  First revenue recognised from its VS3 battery product;
2.  An oversubscribed fundraising of £28.9m before expenses;
3. Submitting Phase 1 of the UK LODES Competition; and
4.  Continued  supply  chain  and  cost  challenges  to  delivering 

contracts.

Other items of operating income and expense for the year were 
£3.4m (2020: £9.8m), of which £3.8m (2020: £1.1m) relates to the 
movement on the provision for onerous contracts. This movement, 
along with those on finance costs and foreign exchange, meant 
a reduced loss after income tax of £21.4m (2020: £26.4m). As all 
of the £4.9m onerous contract provision is expected to unwind in 
2022, this will mean a gross loss for the year ended 2022.

2021  was  the  first  year  to  recognise  revenue  from  the  VS3 
battery product. Of the total revenue of £3.2m (2020: £0.4m), 
most came from the Energy Superhub Oxford (ESO) contract, 
with the balance from a number of other contracts, including 
pre-VS3  contracts,  but  particularly  from  the  Scottish  Water 
contract for its site in Perth.

2021 closed with an inventory balance of £9.9m (2020: £1.9m) 
including  prepaid  inventory  of  £4.1m  (2020:  £0.7m).  Current 
terms of trade mean that most inventory payments are currently 
recorded  as  prepaid  inventory  within  other  current  assets 
because  most  suppliers  require  payment  prior  to  physical 
delivery. Upon physical receipt, prepaid inventory is transferred 
to inventory.

Where contracts are for the delivery of both goods and services, 
the  revenue  on  the  goods  is  recognised  when  control  of  the 
goods transfers, usually on delivery to site, and on the services 
when the performance obligation is fulfilled, usually when the 
contract  is  handed  over.  Both  ESO  and  Scottish  Water  were 
delivered during 2021 with the service element of the revenue 
to be recognised in 2022.

Delivering the contracts in 2021 tested every area of the business 
and the supply chain in particular. Whilst each challenge was 
successfully  overcome,  there  were  impacts  on  the  costs  of 
key inputs which, despite promising signs in late 2020, at best 
remained stubbornly high during the year. Particular examples 
were evident in the indices for shipping costs, which peaked at 
about $20,600 per container during Q3 2021 from about $2,000 
in Q1 2020 and steel 10-ton futures contracts which peaked at 
about $900 from about $600 over the same period. 

Largely as a result of high global input and shipping prices, the 
Group’s cost of sales was £6.6m (2020: £1.2m) which was the 
key driver of the gross loss for the year of £3.4m (2020: £0.8m). 

Administrative  costs  were  £14.4m  (2020:  £9.6m)  of  which 
£9.0m  (2020:  £5.8m)  related  to  staff  costs,  particularly  within 
our customer facing departments (being Commercial, Solutions 
Engineering  and  Customer  Operations)  and  product  facing 
departments  (being  Product  Development  and  Technology). 
This increase represents the continued investment in the Group’s 
capabilities of much of the cash raised in 2020. 

The  balance  above  included  the  European  Marine  Energy 
Centre (EMEC) contract which has since been delivered, along 
with the two CEC contracts, Webcor and Soboba, both due for 
delivery in the third quarter 2022. Along with Yadlamalka and 
Elemental, these contracts equate to revenue of £13.4m.

Remaining  inventory  consisted  mainly  of  stacks  and  balance 
of  system,  along  with  some  electrolyte,  which  means  there 
are  already  sufficient  balance  of  systems,  completed  or  near 
complete,  to  cover  the  remaining  closed  sales  of  Yadlamalka 
and Elemental. 

Cost Down
Whilst the plan at the outset of 2021 was very much to drive 
down costs through a number of measures including increased 
output and further supply chain efficiencies, the reality of the 
continued  COVID-related  global  disruptions  was  that  almost 
all of our input costs increased and almost all of our potential 
customers’ project timelines were extended.

2022  will  see  continued  cost  down  focus  on  the  measures 
above,  an  illustration  being  our  decision  to  commence  the 
switch of suppliers of our balance of system from BCI to Baojia 
whose  sister  company  (Hong  Kong  Hao  Yuan  Shen  Trading) 
owns 3.08% of the company’s equity. Whilst this transition will 
take most of the rest of 2022 to complete, the greater size and 
reach of Baojia is already highlighting cost savings in the supply 
chain. This will allow us to scale faster when the time comes and 
maintain the option to manufacture outside of China should the 
current US tariffs make it advantageous.

Furthermore, moving from single sourcing to dual, or multiple, 
sourcing  will  also  drive  down  costs  and  improve  resilience. 
Opportunities exist in a number of areas, most notably regarding 
sourcing  electrolyte  where  we  have  qualified  one  additional 
supplier  and  are  well  advanced  with  another.  The  scale  and 
access to fixed-price offtake agreements of our new supplier 
has already proved its value by insulating us to a degree from 
the recent peak in the price of vanadium pentoxide.

As  a  counterpoint  to  the  cost  challenges  of  2021,  we  saw 
increasing government support for non-lithium storage solutions 
in each of our three key markets, some of which include explicit 
financial support for further cost down measures as part of the 
programme. The best example being our winning of Phase One 
of the UK Government’s LODES competition run by BEIS. 

Phase 1 of LODES is worth about £0.7m of reimbursed costs to 
Invinity towards the cost of submitting, in conjunction with Pivot 
Power (part of EDF Renewables) and EDF R&D UK (both of whom 
we  also  worked  with  on  ESO),  a  fully  engineered  and  costed 
proposal for Phase 2, which is a 40 MWh storage installation co-
located with solar in the UK. Phase 2 has to be delivered at a 
material cost down relative to 2021 and therefore encapsulates 
our short-term cost down roadmap in much the same way that 
our  medium-term  cost  down  roadmap  is  encapsulated  within 
our JDCA with Siemens Gamesa.

Financial
The Group opened 2021 with £22.0m in cash (2020: £1.2m) and 
closed with £26.4m. Outside of the £23.0m (2020: £10.9m) of 
cash outflows from operating activities, the two highlights were 
a £7.9m increase in combined prepaid inventory and inventory 
(2020: £1.4m) and £27.4m (net of expenses) of receipts from the 
Q4 fundraising, by way of a placing and open offer.

As  part  of  the  placing  and  open  offer,  the  company  granted 
a  total  of  14.5m  short-term  and  14.5m  long-term  warrants. 
The exercise prices are 150p and 225p for the short-term and 
long-term  warrants  respectively  and  the  expiry  dates  are  15 
September 2022 and 16 December 2024. 

In response to the delays discussed elsewhere and to better align 
working capital requirements with expected sales, the Company 
is considering a modest extension to the expiry period of the 
short-term warrants. Should this occur, the Company will seek 
approval from warrant holders at the Company’s next Annual 
General Meeting. 

Going Concern
The  successful  winner,  or  winners,  of  the  second  phase  of 
the  UK  Government’s  LODES  competition  is  expected  to  be 
announced in the first half of 2023. Due to the extensive work 
required in preparing for the submission, contracting is expected 
to complete soon after the winner is announced, along with the 
payment of a material deposit on signing. Similar government 
supported  opportunities  are  in  progress  in  both  the  US  and 
Australia, though LODES is considered the most advanced of 
the three.

Absent  the  exercise  of  any  warrants,  but  including  a  deposit 
from  the  LODES,  or  similar  contract,  the  latest  cash  flow 
forecasts indicate that provided existing contracts are delivered,

new contracts are closed and manufacturing costs reduce as 
forecast, the existing cash will be sufficient to fund the business 
for at least 12 months from the signing of the balance sheet.

The  financial  statements  do  not  include  the  adjustments  that 
would result if the Group were unable to continue as a going 
concern.

14.5m  short-term  warrants  were  granted  in  2021  and  should 
all, or some, of these warrants be exercised prior to expiry on 
15  September  2022  then  the  Company  will  receive  up  to  an 
additional £21.8m of cash. The Group’s cash balances at the end 
of May 2022 totalled £18.1m. Should all of the short-term warrants 
be exercised within the next 12 months then the existing cash will 
be sufficient to fund the business for at least 12 months from the 
signing of the balance sheet. However, the exercise price of the 
short-term warrants is 150p and, at the market close on 22 June 
2022, the Company’s share price is below this exercise price at 
53p. Accordingly there is no certainty that any of the warrants 
will be exercised. 

A change to the terms of the short-term warrants, such as the 
expiry  date,  is  conditional  upon  the  approval  of  the  holders 
of  the  short-term  warrants  and  requires  at  least  50%  of  the 
subscription rights for such class of warrants to vote in favour at 
a General Meeting and there can be no certainty that any such 
change in the terms will be approved. 

Whilst 2021 demonstrated both the support of the Company’s 
investors  and  the  resilience  of  its  organisation,  as  with  many 
groups at this stage of development it remains reliant on timely 
receipts and closely managed costs. Should insufficient short-
term  warrants  be  exercised,  existing  contracts  be  delivered 
more than six-months late or the Group fail to win the LODES, 
or  an  equivalent,  contract  or  close  it  later  than  the  second 
quarter of 2023 then, assuming the Group maintains its forecast 
operational capacity, it will be necessary to raise further funding 
within the next 12 months in order to continue trading and deliver 
on the strategic objectives.

The Group’s need to secure receipts from the exercise of the 
warrants  or  through  winning  new  contracts,  customers  or 
additional  funding  creates  a  material  uncertainty  that  casts 
significant doubt about its ability to continue as a going concern.

water treatment site in Perth, UK – October 2021

In addition to the issues discussed above, the directors have also 
reviewed other varying, and wide-ranging information relating 
to  both  present  and  future  conditions  when  reaching  their 
conclusion regarding going concern. These included the:

   growing opportunities presented by the emergent energy 

storage market;
 growing levels of Government engagement and support in 
the three key markets;

   growing sales pipeline of 686 MWh in May 2022 vs 273 MWh 

in May 2021; and

   validation  of  the  business  provided  by  the  continued 
engagement of EDF following the ESO contract in bidding 
together  for  Phase  2  of  the  LODES  contract  (following  its 
winning of Phase 1).

Outlook
Despite  the  recent  lockdowns  in  China,  there  are  increasing 
signs of a return to global normality. Whilst doing so will take 
time, the ease of doing business, both internally and externally, 
is  already  improving  and  allowing  us  to  be  more  proactive  in 
pursuing sales and cost down opportunities. 

Combining  the  cost  down  opportunities  with  a  growing 
appreciation of the true value of energy security (in part driven 
by geopolitical events such as the war in Ukraine) and the critical 
role of a safe, high throughput non-lithium storage alternative, 
means that the gap between the sales price and our product 
cost  should  narrow  increasingly  rapidly  and  generate  the 
commensurate revenue growth at a suitable margin.

OUR APPROACH TO THE ESG AGENDA
Sustainability Report

The core activity of Invinity’s business is to accelerate 
the global renewable energy transition in pursuit of 
net zero targets. As a Company and as individuals, we 
are committed to taking action on climate change, but 
also understand the importance of a ‘Just Transition’ 
to a low-carbon economy, with no one left behind. This 
underscores our approach to operate responsibly and 
sustainably in the pursuit of our corporate goals. 

As  Environmental,  Social  and  Governance  (ESG)  issues 
become ever more important in a world looking to combat 
climate change, we work continuously to achieve the highest 
standards of sustainability. In June 2022, we formed an ESG 
committee to help oversee, inform, and guide our approach 
to the ESG agenda. Chaired by Non-Executive Director Rajat 
Kohli, the committee will ensure that our ESG performance 
creates additional value for our business, shareholders, and 
wider stakeholders. The Committee is also charged with the 
regular  and  transparent  disclosure  of  our  progress  on  an 
ongoing basis.

ENVIRONMENTAL STEWARDSHIP
A Green Economy Leader
Invinity  is  proud  to  have  been  one  of  the  first  recipients  of 
the  London  Stock  Exchange’s  Green  Economy  Mark,  which 
recognises  companies  that  derive  50%  or  more  of  their  total 
annual  revenues  from  products  and  services  that  contribute 
to  the  global  green  economy.  The  underlying  methodology 
incorporates  the  Green  Revenues  data  model  developed  by 
FTSE  Russell,  which  helps  investors  understand  the  global 
industrial transition to a green and low carbon economy with 
consistent, transparent data and indexes.

Carbon reduction is at the heart of our business model
Our vanadium flow batteries are being installed at sites across 
the world to complement renewable energy generation such as 
solar PV, wind turbines and tidal power, creating ‘dispatchable’, 
on-demand,  clean  power.  This  already  delivers  significant 
carbon savings annually and enables renewables to compete 
directly  with  fossil  fuel  powered  generation  for  the  first  time, 
accelerating  the  phase-out  of  coal  and  gas  from  the  global 
generation mix, without having a destabilising effect on the grid.

Playing our part in the Circular Economy
Invinity’s VFBs are a natural fit for the circular economy as 
the  key  product  components  consist  of  easily  and  widely 
recyclable  materials.  Our  batteries  do  not  contain  rare 
earth or ‘conflict’ minerals such as cobalt and the vanadium 
electrolyte does not degrade with use, meaning that nearly 
100%  of  the  vanadium  itself  can  be  recovered  from  the 
electrolyte for use in other applications. This limits the need 
to constantly utilise ‘new’ raw materials during the life of the 
battery.

Managing our Impacts
As  a  fast-growing  company  that  provides  solutions  which 
help  avoid  and  remove  emissions,  we  are  fully  committed 
to  taking  action  to  reduce  our  own  carbon  footprint.  In 
recognition  of  the  United  Nations  Race  to  Zero  Campaign, 
Invinity has signed up to the SME Climate Commitment.

The SME Climate Commitment
Recognising that climate change poses a threat to the economy, nature and society-at-large, our company commits 
to take action immediately in order to:

1. Halve our greenhouse gas emissions before 2030
2. Achieve net zero emissions before 2050
3. Disclose our progress on a yearly basis

In  doing  so,  we  are  proud  to  be  recognised  by  the  United  Nations  Race  to  Zero  campaign,  and  join  governments, 
businesses, cities, regions, and universities around the world that share the same mission.

Our Carbon Footprint
Invinity reports its carbon footprint in compliance with The 
Greenhouse  Gas  Protocol  (the  world’s  most  widely  used 
greenhouse  gas  reporting  framework)  and  with  the  SME 
Climate  Commitment.  In  line  with  these  requirements,  the 
Company  reports  primarily  on  its  direct  emissions  (Scope 
1)  and  indirect  emissions  arising  from  electricity,  heat  or 
steam consumption (Scope 2), using an operational control 
accounting approach.

In  line  with  SME  Climate  Commitment  guidelines,  Invinity 
falls under the category of “fast growing SMEs that provide 
solutions  which  avoid  or  remove  emissions  as  their  core 
business”.  Therefore,  it  is  considered  appropriate  for  the 
Company  to  report  its  carbon  footprint  on  an  ‘intensity’ 
basis, using the metric of grammes of CO2 equivalent per £ of 
annual revenue.

Supporting the United Nations Sustainable Development 
Goals (UN SDGs)
Invinity  continues  to  recognise  that  the  UN  SDGs  are  the 
blueprint to achieve a better and more sustainable future for 
all. The Company aims to make a meaningful contribution to 
all SDGs and is proud of its particular contribution to Goal 7 
‘Affordable and Clean Energy’, Goal 11 ‘Sustainable Cities and 
Communities’, and Goal 13 ‘Climate Action’.

Invinity’s Canadian Internship 
Programme 

Simon Fraser University
A  third  year  Sustainable  Energy  Engineering  student 
joined us as an Energy Storage Intern for the September 
2021 four-month term. 

The  student  was  primarily  involved  in  supporting  early-
stage  commercial  discussions  with  clients  and  working 
on compiling energy market research for North America 
investigating  the  potential  for  long  duration  energy 
storage  deployment  in  various  territories.  Other  work 
included  a  number  of  small-scale  projects  carrying  out 
some  techno-economic  modelling  for  clients  to  help 
support the development of their business cases. 

This was the student’s first significant experience dealing 
with electricity markets and utilities so there was a good 
opportunity  to  learn  the  fundamentals  of  the  various 
energy  markets  we  were  investigating  as  well  as  gain  a 
good understanding of the different mechanisms energy 
utilities use to charge customers. There was a significant 
amount of data processing and analysis which the student 
hadn’t done to the same extent previously and it was a 
good  opportunity  to  work  with  a  number  of  energy 
modelling tools that we had created in-house to learn how 
the analysis process works from start to finish. 

University of British Colombia
A second year Engineering Physics student joined us as 
a Software Co-op for the January 2022 four-month term. 

The focus for the co-op term was to develop real features 
into our product. They worked in the software team and 
during their term they developed a tool that upgrades our 
Firmware in the field. 

This  was  their  first  co-op  experience  and  they  gained 
valuable  knowledge  on  software  development  in  a 
professional team setting. Taking what they have learned 
on engineering development in their degree and applying 
it  in  a  professional  setting.  They  focused  on  learning 
to  build  robust  code  that  is  maintainable.  It  was  an 
opportunity  for  them  to  understand  the  bigger  picture 
and impact of developing in a team environment where 
their code has real world impact on others development. 
They  gained  firsthand  experience  and  knowledge  from 
the experienced software engineers in the team.

CASE STUDY ENERGY SUPERHUB OXFORD

The  Energy  Superhub  Oxford  (ESO)  project  is  one  of  the 
most  ambitious  urban  decarbonisation  projects  to  have 
been undertaken in the UK to date. The deployment of the 
world’s  first  transmission-connected  vanadium-lithium 
hybrid battery that will support the electrification of Oxford, 
UK, it is a recognised blueprint for other cities to follow as 
part of the transition to net zero. ESO is designed to deliver 
innovation in smart local energy systems by using cutting 
edge energy storage systems.

Invinity’s VFBs were chosen because our technology is able 
to  perform  deep  charge/discharge  cycles  multiple  times 
each day; safely, reliably and without degradation, helping 
to extend the life of the lithium battery. Working closely with 
our  partners,  Invinity  successfully  delivered,  installed  and 
energised a 5 MWh VFB – the UK’s largest flow battery to 
date.

Governance
Invinity’s  Board  of  Directors  believes  that  strong  corporate 
governance  and  risk  management  are  key  to  the  delivery 
of  shareholder  value.  The  business  is  underpinned  by  a 
comprehensive  framework  of  policies  and  risk  management 
systems and the Board has adopted the Quoted Companies 
Alliance  Corporate  Governance  Code  2018  (the  QCA  Code) 
as its corporate governance code which it believes provides a 
flexible model allowing our corporate governance to evolve as 
the business grows.

Further  details  on  the  Company’s  corporate  governance 
practice and compliance with the principles of the QCA Code 
are provided on pages 26-28 of this Annual Report and on the 
website. Details of the risk management systems are provided 
on pages 18-20 of this Annual Report.

Governance Report

Introduction on the Governance Report from the 
Chairman, Neil O’Brien
Invinity is listed on the AIM Market of the London Stock Exchange 
and  as  such  is  required  to  apply  a  recognised  corporate 
governance code. The Company’s shares are also dual-listed on 
the Apex segment of the Aquis Stock Exchange Growth Market 
(AQSE) and the Company’s short-term and long-term warrants 
are listed on the Access segment of the Aquis Stock Exchange 
Growth Market. The Board has adopted the Quoted Companies 
Alliance Corporate Governance Code (the “QCA Code”), which 
is  designed  for  small  to  mid-sized  companies  and  which  has 
been adopted by many AIM companies. The Board has agreed 
that  the  QCA  Code  remains  the  most  appropriate  corporate 
governance code for the Company. 

The Board has considered how the Company applies the ten 
principles of the QCA Code and the Governance Report includes 
the  required  disclosures  and  explanations  where  relevant. 
Further  details  of  the  Company’s  corporate  governance 
practices  are  provided  on  the  Company’s  website  in  the 
Investors section under Corporate Governance. 

Corporate Governance Statement 
The  Board  recognises  that  good  governance  helps  to 
underpin  the  foundations  of  a  solid  and  successful  business 
and  delivery  of  shareholder  value.  Invinity’s  Board,  led  by 
the  Chairman,  is  committed  to  maintaining  high  standards  of 
corporate governance for which the Directors are accountable 
to  shareholders  and  other  stakeholders  and  to  ensuring  that 
the  Company’s  values  are  communicated  and  upheld  across 
the  Group.  The  Board  recognises  that  corporate  governance 
practices  will  need  to  be  regularly  reviewed  as  the  Company 
grows to ensure that they remain appropriate and effective. 

During 2021, the Board continued to strengthen the corporate 
governance framework with a number of initiatives including:

    the appointment of a Senior Independent Director, Jonathan 
Marren, to support the Chairman, to act as an intermediary for 
Board members and as a point of contact for shareholders;
     the appointment of a new Non-Executive Director, Kristina 

Peterson, to broaden the Board’s skill set;

    the introduction of a Board performance appraisal process;
    enhanced Annual Report disclosures in respect of corporate 

governance and remuneration policy and practices;

     the streamlining of Board processes; and
    formalising the risk review process. 

Furthermore,  since  the  year  end,  the  Board  has  established 
an ESG Committee to ensure that the Company delivers on its 
objective of operating responsibly and sustainably. 

Corporate culture 
The Company is committed to ensuring that there is a healthy 
corporate culture. As such, additional policies and procedures 
which  are  designed  to  ensure  that  ethical  and  transparent 
behaviour is recognised and followed across the Group, were 
put in place during the financial year. The policies and procedures 
currently in place include: 

    Code of Conduct
    Whistleblowing Policy 
    Equal Opportunities Policy
    Share Dealing Code 
    Anti-Bribery and Corruption Policy
    Health and Safety Policy 
    Modern Slavery Statement
     Procurement Policy
     Social Impact Policy
    Environmental Impact Policy
     Biodiversity Policy 

Board composition
The Board currently consists of a Non-Executive Chairman, a 
Senior  Independent  Director,  three  Executive  Directors  and 
three Non-Executive Directors. 

During 2021, the Board decided that it would be appropriate to 
appoint a Senior Independent Director to provide a sounding 
board for the Chairman and to act as an intermediary for Board 
members and as a point of contact for shareholders who have 
concerns  which  have not been adequately addressed by the 
Chairman  or  Chief  Executive  Officer.  Accordingly,  Jonathan 
Marren  was  appointed  as  Senior  Independent  Director  with 
effect  from  1  May  2021.  Furthermore,  to  broaden  the  skill  set 
and experience of the Board as well as support the Company’s 
commitment to diversity, Kristina Peterson, who has considerable 
experience in renewables and project finance in North America, 
was appointed as a Non-Executive Director in November 2021. 

Other than any shareholdings in the Company and the receipt 
of fees for acting as Directors, the Chairman and Non-Executive 
Directors have no financial interests in the Company or business 
relationships  that  would  interfere  with  their  independent 
judgement.  Rajat  Kohli  was  originally  appointed  as  a 
representative of Bushveld Minerals pursuant to the terms of an 
investment agreement with the Company but this arrangement 
came to an end in 2021 after Bushveld Minerals disposed of its 
shareholding in the Company.

*See comment below regarding Michael Farrow’s length of tenure/independence 

Independence of Directors 
The  Board  considers  that  the  Chairman  and  all  of  the  Non-
Executive  Directors,  except  Rajat  Kohli,  were  independent 
for  the  whole  of  the  2021  financial  year  notwithstanding 
indicate  otherwise.  While 
circumstances  which  could 
recognising that Michael Farrow has been a Director for 16 years, 
the practicalities of maintaining corporate residency in Jersey 
means that it is advantageous to have an actively participative 
director  located  there.  Neil  O’Brien  and  Jonathan  Marren 
have previously held executive positions within the Company. 
Notwithstanding the shareholdings disclosed on pages 40-41, 
the Board has determined each of these individuals demonstrate 
independence of character and judgement and that there are 
no circumstances which are likely, or could be perceived to be 
likely, to affect their judgement. During 2021, the Board agreed 
that  Rajat  Kohli,  who  had  been  the  nominated  representative 
of Bushveld Minerals until the disposal of their shareholding in 
the Company, should be invited to remain on the Board as an 
independent director.

Role of the Board
The  Board  is  collectively  responsible  for  delivery  of  the 
strategy which is designed to promote the long-term success 
of the Company and to deliver shareholder value. The Board is 
responsible for formulation and approval of the Company’s long-
term objectives and strategy, approval of budgets, oversight of 
operations across the Group, maintenance of internal controls 
and risk management systems and approval of Group policies. 
The Board may delegate specific responsibilities but there is a 
schedule  of  matters  specifically  reserved  for  decision  by  the 
Board to ensure that it exercises control over the key matters 
which could impact on delivery of the Company’s strategy. 

Board skills and responsibilities 
The Directors have a wide range of skills and industry experience 
including technical, operational, commercial and financial both 
in the UK and internationally. The Chairman and Non-Executive 
Directors have held senior management, Board and advisory 
positions and bring relevant experience from their current and 
previous positions. 

A  clearly  defined  organisational  structure  exists  across  the 
Group, with lines of responsibility and delegation of authority to 
executive management. 

Board meetings and processes
The  Board  has  around  eight  scheduled  meetings  each  year 
with other meetings held as required. During 2021, the majority 

of meetings were held by video conference call due to travel 
restrictions related to the COVID-19 pandemic. Informal meetings 
also take place between the Chairman and the Non-Executive 
Directors without the Executive Directors present. 

At each Board meeting, the Board receives an update from the 
CEO on key current activities including HSE and considers the 
Commercial  and  Finance  Reports  and  any  papers  relating  to 
specific matters requiring consideration or approval. 

Non-Executive  Directors  undertake  on  joining  the  Company 
that  they  are  able  to  allocate  sufficient  time  to  discharge 
effectively  their  responsibilities  and  are  required  to  keep 
the  Board  updated  of  any  changes  in  respect  of  their  other 
commitments. 

The  letters  of  appointment  of  the  Non-Executive  Directors 
detail the expected time commitment which is around six Board 
meetings, one General Meeting and two meetings in respect of 
each  of  the  Audit  and  Remuneration  Committees  per  annum 
and  are  required  to  devote  to  the  Company’s  business  such 
additional time as is reasonably necessary by way of preparation 
for or follow-up after any meeting. The Non-Executive Directors 
may  also  be  asked  to  participate  in  other  events  such  as 
marketing, social and client functions with this commitment not 
exceeding around six days per annum.

Board performance evaluation 
During  the  year,  an  internal  performance  evaluation  of  the 
Board  was  undertaken.  Each  Board  member  completed  a 
questionnaire  which  focused  on  strategy,  risks  and  controls, 
Board  structure  and  development,  Board  processes  and  the 
work and composition of the Board committees. The responses 
were  collated  and  summarised  by  an  external  company 
secretary and the key conclusions tabled at a Board meeting.

Board induction, training and outside advice
There is no formal induction process but new Directors receive 
a  briefing  on  AIM  obligations  from  the  Company’s  NOMAD, 
Canaccord  Genuity,  as  well  as  an  appropriate  induction 
according to their requirements. The Board supports Directors 
who wish to receive ongoing training and education relating to 
their duties. 

Independent  legal  advice  is  available  to  Directors  at  the 
Group’s expense if external advice is considered necessary and 
appropriate.

External directorships and interests 
Executive Directors are permitted to engage in other activities 
and businesses outside the Group providing that there is no risk 
of conflict with their executive duties and subject to full Board 
disclosure.

Non-Executive Directors are required to advise the Chairman as 
soon as practicable of any proposed Board appointments which 
could give rise to a conflict with their position as a Director of the 
Company. Details are circulated to other Board members who 
are  invited  to  advise  the  Chairman  if  they  have  any  concerns 
about the proposed appointment.

Conflicts of interest 
The  Board  has  in  place  a  procedure  for  dealing  with  the 
consideration  and  authorisation  of  any  actual  or  potential 
conflicts of interest. All Directors are aware of the requirement 
to advise the Chairman of any situations which could give rise 
to a conflict or potential conflict of interest. If requested by the 
Chairman,  a  Director  will  absent  themselves  from  any  Board 
discussions and decisions on matters where there is an actual or 
perceived conflict of interest.

Company Secretary 
The  Company  Secretary  is  Oak  Secretaries  (Jersey)  Limited 
which  is  100%  owned  by  the  Oak  Group  (Jersey)  Ltd  (Oak 
Group), a Jersey-based limited liability company regulated by 
the Jersey Financial Services Commission. Michael Farrow was a 
director of the Oak Group until his retirement from that company 
in May 2019. The Company has also engaged the services of a 
qualified Company Secretary to assist with the administration 
of  the  share  option  scheme  and  compliance  and  to  provide 
corporate governance advice and general support to the Board 
and its Committees. 

Political and charitable donations 
The Group made no charitable or political donations during the 
year (2020: £nil).

Communication with shareholders 
The Company engages with shareholders in a variety of ways:

Meetings
 Executive  Directors  meet  regularly  with  major  shareholders 
and the investment community which allows exposure to new 
investors,  either  online  or  in  person.  This  process  includes 
presentations, one-to-one meetings and both buy and sell-side 
analyst briefings. During 2021, a roadshow was undertaken in 
connection  with  the  fundraising.  The  Chief  Executive  Officer 
regularly briefs the Board on meetings held and relays the views 
expressed.  Details  of  analyst  research  reports,  press  reports, 
share  trading  and register analyses are shared with Directors 
which ensures that they are kept up to date with the views of 
the investment community. 

Website
The  Company’s  website  is  updated  regularly  and  includes  a 
dedicated  Investor  Relations  section.  This  includes  all  direct 
shareholder  communications,  external  presentations,  Q&As 
with Directors and other relevant documentation so that existing 
and potential investors have access to up-to-date and relevant 
information.

Investor Relations
The Company encourages direct contact from shareholders and 
potential investors by providing an email address and telephone 
number for investors on the website which is monitored by the 
Director of Communications and the Corporate Relations Manager. 
This allows investors to address ad hoc queries to the Company.

Announcements
The Company issues announcements via the RNS news service 
and  as  press  releases  periodically  to  inform  the  market  of 
significant news and developments.

Webinars 
The  Company  hosts  regular  interactive  webinars  which  give 
shareholders the chance to address questions to management. 

Annual Report
The Company’s annual report gives a detailed overview of the 
Company, its strategy, operations, financial position, risk profile 
and remuneration structure and is available in hard copy and on 
the website. This ensures that existing and potential investors 
are provided with the information that they need to make an 
assessment of the Company’s performance and prospects.

Newsletter
The Company issues regular newsletters for Investors and any 
interested  parties  who  have  subscribed  to  receive  updates  on 
the  Company’s  activities  beyond  what  is  issued  through  the 
Regulatory News Service. 

AGM
 In addition to the formal AGM business, the executive team give 
an  operational  and  financial  update  and  shareholders  have  the 
opportunity to address questions to the Board.

Jonathan Marren.

I  am  pleased  to  present  the  report  of  the  Audit  &  Risk 
Committee  for  the  year  ended  31  December  2021.  The 
report  includes  details  of  the  committee’s  activities  during 
the financial year and since the year end. 

Committee composition
The members of the Audit & Risk Committee are Jonathan 
Marren  as  Chairman,  Michael  Farrow  and  Rajat  Kohli  who 
replaced  Neil  O’Brien  as  a  committee  member  during  the 
year. The Board is satisfied that at least one member of the 
Audit  &  Risk  Committee,  Jonathan  Marren,  has  recent  and 
relevant financial experience. 

Meetings 
The  Audit  &  Risk  Committee  met  three  times  during  the 
year and informal discussions were also held both with and 
without  management  present.  The  external  auditors  had 
discussions with the Chairman of the committee during the 
course  of  the  year  and  also  met  the  committee  members 
without management present. 

Only  members  of  the  committee  have  the  right  to  attend

the  Executive  Directors,  members  of  senior  management

Role 
The core terms of reference of the Audit & Risk Committee 
include  reviewing  and  reporting  to  the  Board  on  matters 
relating to: 

  the audit plans of the external auditors; 
  the Group’s overall framework for financial reporting and 
internal controls; 
  the Group’s overall framework for risk management; 
  the accounting policies and practices of the Group; 
  the annual and interim financial reporting carried out by 
the Group; and
  the  independence  and  performance  of  the  external 
auditor. 

The  committee  is  responsible  for  notifying  the  Board  of 
any  significant  concerns  that  the  external  auditors  may 
have arising from their audit work, any matters which may 
materially affect or impair the independence of the external 
auditors, any significant deficiencies or material weaknesses 
in  the  design  or  operation  of  the  Group’s  internal  controls 
and any serious issues of non-compliance. No such concerns 
were identified during the financial period. 

Key matters considered by the committee 
During the year, the issues considered by the committee both 
during and outside formal committee meetings included: 

  Group  financial  disclosures  and  accounting  matters 
relating to the preparation of the financial statements;
  audit plan of the external auditors for the 2020 financial 
year;
  reports of the external auditors concerning its audit and 
review of the financial statements of the Group; 
  2020  Annual  Report  and  Accounts  and  2021  interim 
financial statements;
  external auditors’ fees; and
  terms of reference of the committee. 

During  the  year,  management  reviewed  and  updated  the 
risk matrix which identifies and classifies the key commercial, 
operational,  corporate  and  financial  risks  facing  the  Group 
with  associated  mitigants.  The  risk  matrix  is  reviewed 
regularly  by  the  Board  meetings  and  is  updated  to  reflect 
any changes to the Company’s risk profile. 

Going concern
As  part  of  the  year  end  reporting  process,  management 
prepares  a  detailed  report  including  detailed  cashflow 
forecasts with a number of potential scenarios and sensitivity 
assumptions.  The  committee  reviews  and  challenges 
management’s  assumptions  and  conclusions  in  order  that 
it  can  provide  comfort  to  the  Board  that  management’s 
assessment  has  been  challenged  and  is  supported  and 
that it is appropriate to prepare the financial statements on 
a going concern basis. Further details of the going concern 
assessment  process  are  contained  in  Note  2  of  the  Group 
financial statements on page 55.

External auditors
The committee recommends to the Board the appointment 
of  the  external  auditors,  subject  to  the  approval  of  the 
Company’s shareholders at a general meeting. Shareholders 
in  a  general  meeting  authorise  the  Board  to  fix  the 
remuneration  of  the  external  auditors  and  the  Board  has 
delegated this responsibility to the committee. 

The  committee  is  responsible  for  the  approval  of  the 
provision  of  all  audit  services  and  permitted  non-audit 
services undertaken by the external auditors.

The  committee  actively  considers  the  effectiveness  and 
quality of the external auditors. 

Whistleblowing and anti-bribery
The Company is committed to conducting all of its business 
dealings  in  a  responsible,  honest  and  ethical  manner.  All 
employees,  directors  and  consultants  are  required  to  act 
with  integrity  and  to  have  regard  to  the  Company’s  Code 
of  Conduct  in  their  day-to-day  business  behaviour.  The 
Company also has in place an Anti-Bribery and Corruption 
Policy  and  Procedures  and  arranges  training  for  selected 
employees following a risk analysis.

All  employees  are  made  aware  of  the  Company’s 
whistleblowing  policy  which  includes  contact  details  for 
the  Company’s  internal  whistleblowing  officer  and  an 
independent whistleblowing charity, Public Concern at Work. 

All  employees  are  required  to  undertake  training  on  the 
Market Abuse Regulation in relation to inside information and 
unauthorised trading in the Company’s shares.

the committee will have regard to these when considering 
succession  planning.  When  considering  new  Board 
appointments, the committee will be committed to recruiting 
on merit measured against objective criteria.

Report of the Chairman  
of the Remuneration Committee 

Introduction by the Remuneration Committee Chairman, 
Michael Farrow. 

I am pleased, on behalf of the Remuneration Committee, to 
present  the  Directors’  Remuneration  Report  (‘Report’)  for 
the year ended 31 December 2021. 

The Report is divided into two sections:

  The Policy report which sets out the current 
Remuneration Policy 
  The Annual Report on Remuneration which sets out 
details of the operation of the Remuneration Committee 
and details of the Directors’ remuneration packages for 
the year ended 31 December 2021. It also sets out details 
of the implementation of the Remuneration Policy for 
Executive and Non-Executive Directors for the year 
ending 31 December 2022.

The effects of COVID weighed heavily over the year with the 
overall performance of the Company suffering price increases 
and  delays  both  in  production  and  transportation.  This,  in 
turn, put great pressure on the Executives, notwithstanding 
the achievement of some of their annual bonus performance 
targets. The effort put in by the team is in no doubt and this 
led to significant progress towards improved cohesion within 
the merged business. The management team has amended 
monitoring  processes  and  reporting  of  all  the  key  metrics, 
such as stock control and the production cycle, thus enabling 
much improved internal efficiency. It takes time, however, for 
the results of these improvements to affect financial results 
which  was  exacerbated  by  general  reticence  of  potential 
buyers to commit to transactions.

In 2021, albeit acknowledging the management’s enormous 
efforts, the Remuneration Committee felt obligated to apply 
some  downward  discretion  over  the  final  outturn  of  the 
bonus  awards.  This,  in  no  way,  should  be  interpreted  as  a 
criticism  but  better  aligns  shareholder  outcomes  with  the 
Company’s management. Executive salaries were increased 
for  2022  but  remain  below  the  mid-market  rates  which 
reflects the Canadian and US inclination towards a lower fixed 
and  higher  variable  pay  structure.  The  long-term  incentive 
arrangements remain unadjusted from establishment on the 
merger  in  2020  which  we  believe  to  be  best  practice  and 
avoids  short  term  distortion  of  this  important  alignment  of 
executive reward and shareholder value.

Key  Performance  Indicators  (“KPI”)  have  been  set  for  the 
2022  bonus  which  focus  on  sales,  the  reduction  of  costs 
and the development of new product and key relationships. 
These  KPIs  are  further 
interpreted  and  adjusted  for 
application down the management structure to ensure the 
entire workforce concentrates on the Board’s priorities and 
is rewarded for success. The Remuneration Committee spent 
time refining high level KPIs which should require less annual 
adjustment, while believing that continuity of targets helps 
management over a longer horizon.

We recommend our Report to shareholders although do not 
seek their formal approval. I would be delighted to discuss 
any of the above matters with individual shareholders should 
they so wish.

Directors’ Remuneration Report 

Remuneration policy
This part of the Report sets out the remuneration policy for the Company. The policy for the Executive Directors is determined 
by the Committee and the Committee recommends to the Board any adjustments to salary and bonus awards. The Committee 
also makes recommendations to the Board in respect of the remuneration packages of certain members of the senior team 
based on recommendations from the Chief Executive Officer. Authority is delegated to the Executive Directors to manage the 
remuneration packages of all other employees. Awards of share options to employees under the Company’s Share Option Plan 
are the responsibility of the Board which considers recommendations from the Chief Executive Officer in respect of employees.
The aim of the Committee is to ensure that the remuneration packages are sufficiently competitive to attract, retain and motivate 
individuals of the quality required to contribute towards the strategic objectives of the Group and thereby enhance shareholder 
value. The Committee also aims to ensure that all employees receive rewards that fairly reflect their seniority, level of work and 
contribution to the Company. 

The Company is committed to promoting equal opportunities in employment with all employees and potential employees receiving 
equal treatment. 

Executive Director Policy
The summary of the remuneration policy for the Executive Directors is set out below. Full details of the remuneration packages are 
given in the Report on Remuneration on pages 33-41.

Operation 

Executive Directors receive the same annual salary. 

 Base  salaries  are  reviewed  annually  on  1  January  with  regard  to  the  external  economic 
environment and salary adjustments across the Company.

 The salaries of the Chief Executive Officer and Chief Commercial Officer are designated in 
sterling but paid in local currencies. The salaries are re-based annually to allow for differentials 
arising through foreign exchange. 

Opportunity 

Salary increases will be awarded taking into account the outcome of the review. 

 Salary increases will usually be in line with increases awarded to other employees but the 
Committee  may  make  additional  adjustments  where  there  has  been  a  change  in  role  or 
responsibilities or to reflect a gap in market positioning.

Performance metrics

Pension and Benefits 

Purpose and link to strategy  

 To  provide  an  appropriate  range  of  benefits  and  pension  contributions  to  assist  in  the 
attraction and retention of the calibre of Executive Directors required for delivery of corporate 
and strategic objectives.

Operation  

 The  CEO,  based  in  the  US,  does  not  receive  any  benefits  or  employer  contributions  to  a 
pension plan.

 The  CFO,  based  in  the  UK,  has  income  protection  and  life  assurance  cover.  Benefits  are 
administered internally and a review of providers and prices is conducted annually through a 
broker to ensure that the level of rates and cover remain competitive. A matching employer 
contribution of up to 5% of annual base salary is made to the Group personal pension plan. 

 The CCO, based in Canada, has private medical and dental insurance and life assurance cover. 
He does not receive any employer pension contributions to a pension plan.

Opportunity  

 The benefits and pension packages, which are tailored to the individual Executive Directors, 
are set at a level that the Committee considers is appropriate. 

The value of benefits will vary each year according to the cost of provision.

Performance metrics 

Not applicable for benefits and pension package. 

Annual Bonus 

Purpose and link to strategy  

To reward the achievement of corporate targets.

Operation  

Objectives are set as early as possible in the financial year.

Opportunity  

 The bonuses may be paid in cash and/or shares after the end of the financial year to which 
they relate.

 The annual bonus award is determined as a percentage of base salary based on performance 
against pre-agreed objectives. When deciding on the level of bonus awards, the Committee 
will  have  regard  to  the  extent  to  which  achievement  of  the  objectives  has  contributed  to 
progress against the Company’s strategic drivers.

 The bonus is contractual but at the discretion of the Committee.

 The maximum bonus potential for Executive Directors is 100% of salary. 

Performance metrics  

 The  targets  for  the  Executive  Directors  comprise  the  corporate,  strategic  and  financial 
objectives agreed by the Board. There are no individual objectives.

 The Committee uses its judgement, supported by measurable evidence, to decide the extent 
to which the objectives have been achieved and exercises its discretion to decide on the level 
of bonus awards to be paid.

 The  Committee  considers  whether  operations  have  been  completed  to  acceptable  HSE 
standards and considers whether there were any HSE incidents when considering the level of 
bonus payments.

Share Option Plan (Option Plan)

Purpose and link to strategy 

 To support alignment with shareholders through the link to the creation of shareholder value. 

Operation  

 The Option Plan was introduced in 2018 to replace historical long-term incentive arrangements.

 The Committee makes awards of options at an exercise price based on the prevailing market 
price of the Company’s shares as at the date of grant. The options will vest in equal tranches 
after one, two and three years’ further continuous employment subject to leaver provisions.

Opportunity  

 Option awards are usually made for a three-year term but the Committee has discretion over 
the frequency and quantum of awards. 

Performance metrics 

None.

Further details on the policy
Performance measurement
Annual bonus – the annual bonus is based on a range of corporate and individual objectives that the Board have agreed are key 
to progressing and delivering the Company’s strategy. These can be operational, strategic and financial. Performance targets are 
designed to be stretching but achievable having regard to the Company’s strategic priorities from time to time. 

Option Plan – the Option Plan ensures alignment with shareholders being focussed on share price growth over the medium to long 
term. Vesting of equity awards is phased with options vesting in equal tranches in years 1, 2 and 3 after the date of grant. Options 
granted in exchange for options in predecessor companies at the time of the Merger vest in accordance with the terms of the 
original option grant. The Option Plan for the Executive Directors is the same as that for all other employees. 

Remuneration policy for other employees and consultation
The Company’s policy for all employees is to provide remuneration packages that reward them fairly for their contribution and role 
within the Company. 

All employees are entitled to receive the full range of Company benefits but with different qualifying periods and levels of cover 
depending on seniority. The most senior employees below Board level are eligible to receive an annual bonus based on performance 
against corporate targets. 

All permanent employees have been granted options under the Option Plan on the same terms as the Executive Directors but 
proportionate  to  their  employment  contracts  and  their  ability  to  contribute  towards  the  Company’s  strategic  objectives.  This 
ensures that an element of remuneration is deliverable through a scheme that aligns participants with shareholders. 

The Company does not consult with employees on the effectiveness and appropriateness of the policy but, in considering individual 
salary increases, the Committee does have regard to salary increases across the Company. 

Recruitment 
In the case of recruiting a new Executive Director, the Committee can use all the existing components of remuneration as set out 
in the policy table. 

The salary of a new appointee will be determined by reference to the experience and skills of the individual, market data, internal 
comparatives and the candidate’s current remuneration. New appointees may be entitled to receive the full range of Company 
benefits on joining and, if the Committee considers it appropriate, a matching employer contribution of up to 5% of annual base 
salary to the Group personal pension plan.

 The annual bonus would operate as  
outlined in the Policy for existing Executive  
Directors. The relevant maximum will be  
pro-rated to reflect the period of employment  
over the year. Consideration will be given to  
the appropriate performance targets at the  
time of joining. 

100% of base salary in respect of the  
current financial year.  

Option Plan 

 The Option Plan would operate as outlined  
in the policy for existing Directors. An award  
of options may be granted on joining subject  
to the Company being in an open dealing period. 

Committee discretion.  

Service contracts, exit payments and change of control provisions 
The Executive Directors have rolling term service agreements with the Company. Details of the Directors’ service contracts and 
appointment dates are as follows:

The Directors’ service contracts are available to view at the Company’s registered office and prior to each Annual General Meeting 
at the venue for the meeting. 

The notice period for the Executive Directors is six months’ notice in writing by either party. The Company has the right to make 
a payment in lieu of notice of six months’ salary and, in the case of the CEO, a reimbursement of certain benefits if relevant. The 
Committee will consider termination payments on a case-by-case basis. It will consider the terms of the Director’s contract and the 
circumstances of the termination and might consider making an ex-gratia payment where the circumstances and/or a Director’s 
contribution to the Company justifies this. If an ex-gratia payment is to be made, the Committee will ensure that it is satisfied that it 
is in the best interests of the Company to make such a payment and that there is no “reward for failure”.

The Committee also has discretion to settle any other amounts which it considers are reasonably due to the Director such as 
where the parties agree to enter into a settlement agreement and the individual is required to seek independent legal advice. 
The Committee can approve new contractual arrangements with a departing Director covering matters such as confidentiality or 
restrictive covenants and/or consultancy arrangements where it believes this is in the best interests of the Company.

Treatment of incentives for leavers and following a corporate event
a) Annual bonus 
In relation to annual bonuses, a bonus payment will not usually be made if the Director is under notice at the bonus payment date 
or has already left. 

b) Option Plan
In relation to awards granted under the Option Plan, all unvested options will lapse on cessation of employment. In Good leaver and 
Intermediate leaver circumstances (as defined in the Option Plan rules), all vested options will be retained and will be exercisable for 
a period of six months after the cessation of employment or 12 months in the case of death. The Committee has discretion to further 
extend the exercise period for Intermediate leavers and to allow the vesting of all or part of the unvested portion of an option for 
Good leavers. 

In the event of change of control of the Company, all vested options will remain exercisable for a period of six months after the 
change of control and the Committee has the discretion to allow the vesting of all or part of the unvested portion of an option. 
Subject to the agreement of any acquiring company, option holders may be offered the opportunity to exchange their options for 
equivalent options over shares in the acquiring company for a period of up to six months from the change of control taking effect.

The Option Plan rules include malus and clawback provisions whereby the Committee has discretion to reduce the number of 
shares subject to an existing Option award in the event that an Option has been granted or has vested on the basis of any incorrect 
information relevant to the setting of any performance condition or condition of satisfaction including a material misstatement in the 
published financial results or in the event of fraud or misconduct by an Option holder including where an Option holder has been 
dismissed for cause. In the case of an Option which has been exercised, the Committee can require the Option holder to repay the 
Company an amount equal to the benefit by way of a transfer of shares or cash. 

The Board can amend the Option Plan rules at any time provided that an option holder’s existing rights cannot be adversely 
affected without the Option holder’s consent.

Additional information in respect of single figure table of remuneration for the year ended 31 December 2021
Annual bonus
In respect of the financial period, the Committee agreed that the Executive Director annual bonus opportunity would be up to 
100 per cent of base salary. The Committee had agreed objectives with equal weighting relating to project delivery, signed sales 
contracts and development of strategic relationships. 

The Committee agreed that the final bonus calculation for 2021 was 47%. The Committee had noted that a higher bonus amount 
was justified on the basis of the extent to which the objectives had been achieved but felt it appropriate to scale back the level of 
the bonus awards to ensure better alignment with shareholder outcomes.

Awards of share options during the financial year
There were no options granted to Executive Directors during the financial year. 

Implementation of Executive Director remuneration policy for 2022
Base salaries
The base salaries of the Executive Directors were increased in the range of 5.8% to 6.7%, the differential being due to foreign 
exchange differences, with effect from 1 April 2022. 

Annual bonus
For 2022, the Executive Director annual bonus will be determined as a percentage of base salary based on performance against 
pre-agreed corporate objectives. The maximum bonus potential is 100% of base salary. 

For the financial year ending 31 December 2022, the Committee has agreed objectives with a range of weightings relating to signed 
sales contracts, share price performance, achievement of milestones on the joint development program with Gamesa Electric and 
production cost reductions. 

Option Plan
The Committee does not plan to make any awards of share options to Executive Directors under the Option Plan during the 2022 
financial year.

Benefits and pension contributions 
The Executive Directors will receive the benefits and pension contributions in line with the policy.

Implementation of Non-Executive Director remuneration policy for 2022
No adjustments to Non-Executive Director fees are planned for the 2022 financial year. The Board has proposed the establishment 
of an ESG Committee during 2022. This will be chaired by a Non-Executive Director who will receive an annual fee of £5,000 in line 
with the Chairs of the Remuneration and Audit & Risk Committee.

Statement of Directors’ Responsibilities  
in Respect of the Financial Statements

The  directors  are  responsible  for  preparing  the  Annual 
Report  and  the  Financial  Statements  in  accordance  with 
applicable law and regulation.

Directors’ confirmations
In the case of each director in office at the date the Directors’ 
report is approved:

The  Companies  (Jersey)  Law,  1991  requires  the  directors  to 
prepare financial statements for each financial year. Under that 
law the directors have prepared the Group financial statements 
in accordance with International Financial Reporting Standards 
(IFRS) as adopted in the European Union.

Under  The  Companies  (Jersey)  Law,  1991,  directors  must  not 
approve the financial statements unless they are satisfied that 
they give a true and fair view of the state of affairs of the Group 
and of the profit or loss of the Group for that period. In preparing 
the financial statements, the directors are required to:

 select suitable accounting policies and then apply them 
consistently;
 state whether applicable IFRS as adopted in the 
European Union have been followed, subject to any 
material departures disclosed and explained in the 
financial statements;
 make judgements and accounting estimates that are 
reasonable and prudent; and
 prepare the financial statements on the going concern 
basis unless it is inappropriate to presume that the 
Group will continue in business.

The directors are also responsible for safeguarding the assets 
of the Group and hence for taking reasonable steps for the 
prevention and detection of fraud and other irregularities.

The directors are responsible for keeping proper accounting 
records that disclose with reasonable accuracy at any time 
the  financial  position  of  the  Company  and  enable  them 
to  ensure  that  the  financial  statements  comply  with  The 
Companies Law (Jersey), 1991.

The  directors  are  responsible  for  the  maintenance  and 
integrity  of  the  Group’s  website.  Legislation  in  the  United 
Kingdom  governing  the  preparation  and  dissemination 
of  financial  statements  may  differ  from  legislation  in  other 
jurisdictions.

 so far as the Director is aware, there is no relevant audit 
information of which the Group’s auditors are unaware; 
and
 they have taken all the steps that they ought to have 
taken as a director in order to make themselves aware 
of any relevant audit information and to establish that 
the Group’s auditors are aware of that information.

Independent Auditors’ Report to the  
Members of Invinity Energy Systems plc

Report on the audit of the financial statements
Opinion
In our opinion, Invinity Energy Systems Plc’s Group financial statements:

 give a true and fair view of the state of the Group’s affairs as at 31 December 2021 and of its loss and cash flows for the year 
then ended;
 have been properly prepared in accordance with International Financial Reporting Standards as adopted in the European 
Union; and

  have been prepared in accordance with the requirements of the Companies (Jersey) Law 1991.

We have audited the financial statements, included within the Annual Report and Financial Statements 2021 (the “Annual Report”), 
which comprise: the consolidated statement of financial position as at 31 December 2021; the consolidated statement of profit 
and loss, the consolidated statement of comprehensive income, the consolidated statement of cash flows and the consolidated 
statement of changes in equity for the year then ended; and the notes to the financial statements, which include a description of 
the significant accounting policies.

Basis for opinion
We  conducted  our  audit  in  accordance  with  International  Standards  on  Auditing  (UK)  (“ISAs  (UK)”)  and  applicable  law.  Our 
responsibilities under ISAs (UK) are further described in the Auditors’ responsibilities for the audit of the financial statements section 
of our report. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Independence
We remained independent of the Group in accordance with the ethical requirements that are relevant to our audit of the financial 
statements in the UK, which includes the FRC’s Ethical Standard, as applicable to listed entities, and we have fulfilled our other 
ethical responsibilities in accordance with these requirements.

Material uncertainty related to going concern
In forming our opinion on the financial statements, which is not modified, we have considered the adequacy of the disclosure 
made in note 2 to the financial statements concerning the Group’s ability to continue as a going concern. Whilst the group has 
secured £29 million additional funding during the year through a placing and open offer, the appropriateness of the going concern 
assessment of the Group is dependent on existing contracts being delivered, new contracts being closed, and manufacturing 
costs reducing in line with forecast. If these conditions are not met, the Group is forecasted to require additional funding in order 
to continue trading and delivering on its strategic objectives. Also, there is no certainty that short-term warrants, which are due 
to expire in September 2022 and which may provide additional funding, will be exercised. These conditions, along with the other 
matters explained in note 2 to the financial statements, indicate the existence of a material uncertainty which may cast significant 
doubt about the Group’s ability to continue as a going concern. The financial statements do not include the adjustments that would 
result if the Group were unable to continue as a going concern.

In auditing the financial statements, we have concluded that the directors’ use of the going concern basis of accounting in the 
preparation of the financial statements is appropriate.

Our evaluation of the directors’ assessment of the Group’s ability to continue to adopt the going concern basis of accounting included:

 obtaining future cash flow forecasts, covering base case and a severe but plausible downside case, for a period of at least  
12 months from the date of approval of the financial statements. We assessed the forecast assumptions used in the base and 
severe but plausible downside scenarios;
 review of past forecasting accuracy by the directors;
 testing the mathematical accuracy of the forecasts;
 corroborating the forecast budgeted revenue with confirmed sales orders or revenue pipeline of the Group;
 comparing the assumptions used within the going concern model to the board approved budgets and business plans;
 reviewing and evaluating management’s sensitivities and performing additional sensitivity analysis over key assumptions in 
the model in order to assess the potential impact of a range of possible outcomes; and
 reading the disclosures in the financial statements and checking these were consistent with the Group’s plans for future 
fundraising and the group’s current funding position.

Our responsibilities and the responsibilities of the directors with respect to going concern are described in the relevant sections of 
this report.

Our audit approach
Context
Invinity Energy Systems plc is an independent, Jersey incorporated company. Its key subsidiaries are based in the UK, Canada 
and United States of America. The principal activities of the company and its subsidiaries relate to the manufacture and sale of 
vanadium flow battery systems plus associated installation, warranty and other services. Its manufacturing and assembly sites are 
located in the UK and Canada.

Overview
Audit scope

 We conducted full scope audits on four components and the audit of specified balances and classes of transactions on 
one component. The scope of work at each component was determined by its contribution to the group’s overall financial 
performance and its risk profile.
 We engaged our network firm in Canada to perform the audit procedures for components based in the United States of 
America and Canada. The work on the other components was performed by us.
 The components where audit work was performed accounted for approximately 97% of total assets.

Key audit matters

 Material uncertainty related to going concern
 Revenue Recognition
 Onerous Contracts Provision and Inventory Valuation
 Warranty Provision
 Impairment of goodwill

Materiality

 Overall materiality: £650,000 (2020: £500,000) based on 1% of total assets.
 Performance materiality: £487,500 (2020: £375,000).

The scope of our audit
As part of designing our audit, we determined materiality and assessed the risks of material misstatement in the financial statements.

Key audit matters
Key audit matters are those matters that, in the auditors’ professional judgement, were of most significance in the audit of the 
financial statements of the current period and include the most significant assessed risks of material misstatement (whether or not 
due to fraud) identified by the auditors, including those which had the greatest effect on: the overall audit strategy; the allocation 
of resources in the audit; and directing the efforts of the engagement team. These matters, and any comments we make on the 
results of our procedures thereon, were addressed in the context of our audit of the financial statements as a whole, and in forming 
our opinion thereon, and we do not provide a separate opinion on these matters.

In addition to going concern, described in the Material uncertainty related to going concern section above, we determined the 
matters described below to be the key audit matters to be communicated in our report. This is not a complete list of all risks 
identified by our audit.

Revenue Recognition, Onerous Contract Provision and Inventory Valuation and Warranty Provision are new key audit matters 
this year. Accounting for acquisition and purchase price allocation of Avalon Battery Corporation (Note 7) and COVID-19 risks and 
uncertainties (Note 2), which were key audit matters last year, are no longer included because of their nature being specific to the 
2020 financial year end. Otherwise, the key audit matters below are consistent with last year.

Key audit matter 

How our audit addressed the key audit matter

Revenue Recognition 
The  Group  recognised  revenue  totalling  £3.2m  for  the  year 
(2020: £0.4m). A total of £2.8m of this related to two contracts in 
the UK; Energy Superhub Oxford (ESO) and Scottish Water. The 
Group has identified 4 performance obligations under IFRS 15. 

We focused on this area due to the greater magnitude of revenue 
being  recognised  in  the  current  year  and  the  complexities 
associated with IFRS 15 when selling under contract. (Note 4)

Onerous Contracts Provision and Inventory Valuation 
At the balance sheet date the Group has inventory of £5.8m and 
an onerous contract provision of £4.9m. The onerous contract 
provision relates to 8 contracts. 

We  have  focused  on  the  completeness  of  this  provision  and 
valuation of inventory as determining the appropriate provision 
for contracts that are, or are expected to become, loss making 
requires a significant level of judgement. The calculation of the 
provision will require identification of the costs expected to be 
incurred and the benefits expected to be derived from individual 
contracts. 

Further,  the  assessment  of  inventory  valuation  is  inherently 
subjective and requires the exercise of judgment in determining 
the appropriate amount of provision. (Note 21)

We  obtained  and  assessed  management’s  IFRS  15  revenue 
recognition  paper  including  the  identification  of  the  different 
performance  obligations.  We  agreed  with  management’s 
conclusion  on  performance  obligations  when  considered 
against  IFRS  15’s  concept  of  transfer  of  control.  A  key  factor 
being that a customer has control of the battery system once 
delivered on site but not yet installed. 

For  all  contracts  where  a  material  amount  of  revenue  was 
recognised  in  the  current  year  we  performed  the  following 
testing: 

 obtained the underlying contract;
 tested management’s recognition of revenue against the 
performance obligations outlined in their accounting policy 
agreeing that point in time recognition is appropriate;
  corroborated the amount and allocation of the transaction 
price against the contract and the performance obligations; 
and 
  corroborated transfer of control for the battery systems by 
reference to supporting evidence including goods delivery 
notes and shipping documentation. 

Based on our work performed we believe revenue recognition 
is correctly applied.

In testing the completeness of the onerous contract provision 
and valuation of inventory we performed the following: 

 obtained the complete list of contracts signed with 
customers to check if an onerous contract provision had 
been recognised or at least considered for each one;
 obtained management’s onerous contract provision 
calculation and tested the constituent parts to 
management’s assumptions and corroborating evidence. 
Part of this test was to assess whether or not what was 
recognised was sufficient in light of the evidence obtained;
 considered losses made on contracts to date and 
compared this to the calculated forecasted losses on 
contracts to identify any inconsistencies; and
 tested the recoverability of inventory taking into account 
whether the costs of raw materials and finished goods 
would be recovered through future sales based on current 
contracts as an indicator. 

Based on work performed we identified no indicators that would 
suggest management’s assessment was materially misstated.

Key audit matter 

How our audit addressed the key audit matter

Warranty Provision 
At  the  balance  sheet  date  the  Group  has  total  warranty 
provisions of £1.1m including £0.9m related to legacy products. 

In  testing  the  completeness  of  the  warranty  provision  we 
performed the following testing: 

The  assessment  of  future  costs  is  inherently  subjective  and 
requires the exercise of judgment in determining the appropriate 
amount of provision that may be required and as such we have 
focused on the completeness of this provision. (Note 21)

Impairment of goodwill
The  Group  holds  goodwill  of  £23.9m.  IAS  36  Impairment  of 
assets requires an annual impairment assessment to be carried 
out  for  all  indefinite  life  intangibles  (goodwill)  and  whenever 
there are any indications of impairment for all other assets. 

We  focused  on  this  area  due  to  the  material  nature  of  the 
goodwill and given that the Group is currently incurring losses, 
there is a risk that the value of goodwill may not be recoverable. 

Management  has  determined  the  recoverable  amount  of  the 
relevant  cash  generating  unit  as  at  31  December  2021  based 
on  fair  value  less  costs  of  disposal  (in  line  with  the  approach 
adopted in 31 December 2020). (Note 15)

 obtained management’s warranty provision calculation and 
tested key inputs such as warranty period and number of 
stacks for each contract included under warranty; 
 tested management’s fail rate calculation using supporting 
evidence of stacks failed to date; and
 tested management’s estimates of stack costs and labour 
costs to supporting evidence.

We noted no issues from the above testing. 

The specific provisions in place relating to the legacy products 
have been in place since last year. We tested the build up of the 
costs for the specific provision and concluded these as being 
reasonable.  Based  on  the  work  performed,  we  determined 
that  the  assumptions  used,  and  the  approach  taken,  were 
reasonable.

In  auditing  the  impairment  assessment  we  performed  the 
following: 

 we considered the appropriateness of using the fair value 
less costs to sell approach; 
 we corroborated the share price at the balance sheet date 
and checked the accuracy of the market capitalisation 
calculation; 
 assessed the inclusion of all appropriate assets and liabilities 
in the cash generating unit carrying value calculation and 
agreed that all relevant balances had been included; and
  verified the adequacy of relevant disclosures in the group  

financial statements. 

Based  on  the  work  performed,  we  determined  that  the 
assumptions used, and the approach taken, were reasonable. 

The recoverability of the goodwill is interlinked with the going 
concern assumption therefore the recoverability of the asset is 
at risk should the Group not continue as a going concern.

How we tailored the audit scope
We tailored the scope of our audit to ensure that we performed enough work to be able to give an opinion on the financial 
statements as a whole, taking into account the structure of the group, the accounting processes and controls, and the industry in 
which it operates.

The Group has one segment and cash generating unit. Following the acquisition of Avalon Battery Corporation, the Group has two 
manufacturing and assembly locations in the UK and Canada. The accounting and financial reporting functions are also based in 
these two regions.

Our group scoping was based on total assets within each component. We identified four components (the Company, Invinity Energy 
(UK) Limited, Invinity Energy Systems (Canada) Corporation and Invinity Energy Systems (US) Corporation) which comprised a high 
proportion of total Group assets which required an audit of their complete financial information. One other component was subject 
to procedures over the provisions and contract liabilities financial statement line item level to obtain sufficient coverage.

The audit work was performed by the group engagement team based in the UK and component auditors based in Canada. We 
maintained regular communication and conducted formal interim and year-end conference calls with component team, as well as 
reviewing the audit work and reports to us.

Together the above scoping gave appropriate coverage of all material balances at a Group level. On a consolidated basis, these 
provided coverage of 98% of total assets.

Materiality
The scope of our audit was influenced by our application of materiality. We set certain quantitative thresholds for materiality. These, 
together with qualitative considerations, helped us to determine the scope of our audit and the nature, timing and extent of our 
audit procedures on the individual financial statement line items and disclosures and in evaluating the effect of misstatements, both 
individually and in aggregate on the financial statements as a whole.

Based on our professional judgement, we determined materiality for the financial statements as a whole as follows:

Overall Group materiality 

£650,000 (2020: £500,000).

How we determined it 

1% of total assets

Rationale for benchmark applied 

 We believe that total assets are an appropriate measure for the Group given the current 
stage of development of the business and products.

For each component in the scope of our group audit, we allocated a materiality that is less than our overall group materiality. The 
range of materiality allocated across components was between £224,000 and £550,000.

We use performance materiality to reduce to an appropriately low level the probability that the aggregate of uncorrected and 
undetected misstatements exceeds overall materiality. Specifically, we use performance materiality in determining the scope of 
our audit and the nature and extent of our testing of account balances, classes of transactions and disclosures, for example in 
determining sample sizes. Our performance materiality was 75% (2020: 75%) of overall materiality, amounting to £487,500 (2020: 
£375,000) for the group financial statements.

In determining the performance materiality, we considered a number of factors – the history of misstatements, risk assessment 
and aggregation risk and the effectiveness of controls – and concluded that an amount in the middle of our normal range was 
appropriate.

We agreed with those charged with governance that we would report to them misstatements identified during our audit above 
£32,500 (2020: £25,000) as well as misstatements below that amount that, in our view, warranted reporting for qualitative reasons.

Reporting on other information
The other information comprises all of the information in the Annual Report other than the financial statements and our auditors’ 
report thereon. The directors are responsible for the other information. Our opinion on the financial statements does not cover the 
other information and, accordingly, we do not express an audit opinion or any form of assurance thereon.

In connection with our audit of the financial statements, our responsibility is to read the other information and, in doing so, consider 
whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the audit, or 
otherwise appears to be materially misstated. If we identify an apparent material inconsistency or material misstatement, we are 
required to perform procedures to conclude whether there is a material misstatement of the financial statements or a material 
misstatement of the other information. If, based on the work we have performed, we conclude that there is a material misstatement 
of this other information, we are required to report that fact. We have nothing to report based on these responsibilities.

Responsibilities for the financial statements and the audit
Responsibilities of the directors for the financial statements
As explained more fully in the Statement of the Directors’ Responsibilities in Respect of the Financial Statements, the directors are 
responsible for the preparation of the financial statements in accordance with the applicable framework and for being satisfied that 
they give a true and fair view. The directors are also responsible for such internal control as they determine is necessary to enable 
the preparation of financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the financial statements, the directors are responsible for assessing the Group’s ability to continue as a going concern, 
disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the directors 
either intend to liquidate the Group or to cease operations, or have no realistic alternative but to do so.

Auditors’ responsibilities for the audit of the financial statements
Our  objectives  are  to  obtain  reasonable  assurance  about  whether  the  financial  statements  as  a  whole  are  free  from  material 
misstatement, whether due to fraud or error, and to issue an auditors’ report that includes our opinion. Reasonable assurance 
is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a 
material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the 
aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial 
statements.

Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our 
responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our 
procedures are capable of detecting irregularities, including fraud, is detailed below.

Based on our understanding of the Group and industry, we identified that the principal risks of non-compliance with laws and 
regulations related to Companies (Jersey) Law 1991, tax legislation and employment legislation, and we considered the extent 
to which non-compliance might have a material effect on the financial statements. We evaluated management’s incentives and 
opportunities for fraudulent manipulation of the financial statements (including the risk of override of controls) and determined that 
the principal risks were related to manipulation of financial results (such as revenue) and potential management bias in accounting 
estimates to improve the performance of the Group. The group engagement team shared this risk assessment with the component 
auditors so that they could include appropriate audit procedures in response to such risks in their work. Audit procedures performed 
by the group engagement team and/or component auditors included:

 Evaluation of the design effectiveness of management’s controls designed to prevent and detect irregularities;
 Inquiries with the Board of Directors and Chief Financial Officer, including consideration of known or suspected instances of 
tax matters, employment regulations and non-compliance with laws and regulations and fraud;
 Review of board minutes;
 Challenging assumptions made by management in its significant accounting estimates, in particular in relation to impairment 
of intangible assets, provision for warranty, inventory and onerous contracts; and
 Identifying and testing the validity of journal entries, in particular any journal entries posted with unusual revenue account 
combinations.

There are inherent limitations in the audit procedures described above. We are less likely to become aware of instances of non-
compliance with laws and regulations that are not closely related to events and transactions reflected in the financial statements. 
Also, the risk of not detecting a material misstatement due to fraud is higher than the risk of not detecting one resulting from error, 
as fraud may involve deliberate concealment by, for example, forgery or intentional misrepresentations, or through collusion.

Our audit testing might include testing complete populations of certain transactions and balances, possibly using data auditing 
techniques. However, it typically involves selecting a limited number of items for testing, rather than testing complete populations. 
We will often seek to target particular items for testing based on their size or risk characteristics. In other cases, we will use audit 
sampling to enable us to draw a conclusion about the population from which the sample is selected.

A further description of our responsibilities for the audit of the financial statements is located on the FRC’s website at: www.frc.org.
uk/auditorsresponsibilities. This description forms part of our auditors’ report.

Notes
(forming part of the consolidated historical financial information)

1 General Information
Invinity Energy Systems plc (the ‘Company’) is a public company limited by shares incorporated and domiciled in Jersey. The 
registered office address is Third Floor, IFC5, Castle Street, St. Helier, JE2 3BY, Jersey.

The Company is listed on the Alternative Investment Market of the London Stock Exchange with the ticker symbol IES.L.

The principal activities of the Company and its subsidiaries (together the ‘Group’) relate to the manufacture and sale of vanadium 
flow battery systems and associated installation, warranty and other services.

2 Summary of significant accounting policies
Basis of preparation
These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards as 
adopted by the European Union, the associated interpretations issued by the IFRS Interpretations Committee (together ‘IFRS’) and 
in accordance with the Companies (Jersey) Law 1991.

Separate  presentation  of  the  parent  company  financial  statements  is  not  required  by  the  Companies  (Jersey)  Law  1991  and, 
accordingly, such statements have not been included in this report.

The significant accounting policies applied in preparing these consolidated financial statements are set out below. These policies 
have been consistently applied throughout the period and to each subsidiary within the Group.

The financial statements have been prepared under the historical cost convention except where stated.

Going concern
The successful winner, or winners, of the second phase of the UK Government’s LODES competition is expected to be announced 
in the first half of 2023. Due to the extensive work required in preparing for the submission, contracting is expected to complete 
soon after the winner is announced, along with the payment of a material deposit on signing. Similar government supported 
opportunities are in progress in both the US and Australia, though LODES is considered the most advanced of the three.

Absent the exercise of any warrants as described below, but including a deposit from the LODES, or similar contract, the latest cash 
flow forecasts indicate that provided existing contracts are delivered, new contracts are closed and manufacturing costs reduce as 
forecast, the existing cash will be sufficient to fund the business for at least 12 months from the signing of the balance sheet.

14.5m  short-term  warrants  were  granted  in  2021  and  should  all,  or  some,  of  these  warrants  be  exercised  prior  to  expiry  on 
15 September 2022 then the Company will receive up to an additional £21.8m of cash. The Group’s cash balances at the end of May 
2022 totalled £18.1m. Should all of the short-term warrants be exercised within the next 12 months then the existing cash will be 
sufficient to fund the business for at least 12 months from the signing of the balance sheet.

However, the exercise price of the short-term warrants is 150p and, at the market close on 22 June 2022, the Company’s share price 
is below this exercise price at 53p. Accordingly there is no certainty that any of the warrants will be exercised. 

A change to the terms of the short-term warrants, such as the expiry date, is conditional upon the approval of the holders of the 
short-term warrants and requires at least 50% of the subscription rights for such class of warrants to vote in favour at a General 
Meeting and there can be no certainty that any such change in the terms will be approved. 

Whilst 2021 demonstrated both the support of the Company’s investors and the resilience of its organisation, as with many groups 
at this stage of development it remains reliant on timely receipts and closely managed costs. Should insufficient short-term warrants 
be exercised, existing contracts be delivered more than six-months late or the Group fail to win the LODES, or an equivalent, 
contract or close it later than the second quarter of 2023 then, assuming the Group maintains its forecast operational capacity, it will 
be necessary to raise further funding within the next 12 months in order to continue trading and deliver on the strategic objectives.

The Group’s need to secure receipts from the exercise of the warrants or through winning new contracts, customers or additional 
funding creates a material uncertainty that casts significant doubt about its ability to continue as a going concern. The financial 
statements do not include the adjustments that would result if the Group were unable to continue as a going concern.

55

Annual Report and Financial Statements 2021UK  /  US  /  CANADA  /  AUSTRALIAINTRODUCTIONSTRATEGIC REPORTGOVERNANCEFINANCIAL STATEMENTSInvinity Energy Systems plcNotes
(forming part of the consolidated historical financial information)

In addition to the issues discussed above, the directors have also reviewed other varying, and wide-ranging information relating to 
both present and future conditions when reaching their conclusion regarding going concern. These included the:

   growing opportunities presented by the emergent energy storage market;
   growing levels of Government engagement and support in the three key markets;
   growing sales pipeline of 686 MWh in May 2022 vs 273 MWh in May 2021; and

 validation of the business provided by the continued engagement of EDF following the ESO contract in bidding together for 
Phase 2 of the LODES contract (following its winning of Phase 1).

Foreign currency
Presentation currency
The consolidated financial statements are presented in Great British Pounds (GBP) rounded to the nearest thousand (£000), except 
where otherwise indicated. 

Functional currency 
Items included in the financial information of the individual companies that comprise the Group are measured using the currency of 
the primary economic environment in which each subsidiary operates (its functional currency).

Whilst Jersey uses the Jersey Pound as its currency, Jersey is in a currency union with the United Kingdom and so the functional 
currency of the parent company of the Group has been determined to be GBP.

Foreign currency transactions
Transactions in currencies other than an entity’s functional currency (foreign currencies) are translated using the exchange rate 
on the date of the transaction. Foreign exchange gains and losses resulting from the settlement of transactions denominated in a 
foreign currency are translated into GBP using the relevant exchange rate at the date of the transaction.

Foreign exchange gains and losses resulting from the settlement of foreign currency transactions and from the translation at 
the balance sheet date of monetary assets and liabilities denominated in foreign currencies, are recognised in the consolidated 
statement of comprehensive loss within gains/ (losses) on foreign currency transactions.

Foreign currency gains/(losses) realised on the retranslation of subsidiaries as part of the year-end consolidation are recorded in the 
translation reserve that forms a part of shareholders’ funds in the consolidated financial statements of the Group.

Consolidation of subsidiaries
Subsidiaries are all entities over which the Company has control. The Company controls an entity when it is exposed to, or has rights 
over, variable returns from its involvement with the entity and can affect those returns through its ability to exercise control over the 
entity. Subsidiaries are consolidated in the Group financial statements from the date at which control is transferred to the Company. 

Subsidiaries are deconsolidated from the date that control ceases. The ability to control an entity may cease because of the sale of 
a subsidiary or other change in the Company’s shareholding in that subsidiary, voting rights or board representation.

Foreign operations
Subsidiaries of the Company that are based in countries other than the UK or Jersey may have functional currencies that are 
different from that of the Company. In addition, the Group financial statements are presented in GBP. The assets and liabilities 
of foreign subsidiaries consolidated into these financial statements are translated into the Group’s presentational currency using 
exchange rates prevailing at the end of the reporting period. Income and expense items are similarly translated using the month-
end rate for each month during the year. The exchange rates on the actual dates of transactions are used where exchange rates 
fluctuate significantly within a month. Exchange differences arising on consolidation are recognised in other comprehensive income 
and are accumulated as part of shareholder’s equity.

Investments in associates and joint arrangements
Associates are entities where the Company can exert significant influence but is not able to exercise control.

Joint arrangements may be incorporated, where an entity exists, or may be unincorporated, where the venture or joint operation is 
governed by contract or other arrangement between two or more parties. The Company is not currently party to any unincorporated 
joint arrangements.

Notes
(forming part of the consolidated historical financial information)

The Group accounts for its interests in associates and incorporated joint ventures using the equity method of accounting where the 
relevant investment is initially recorded at the cost to acquire the interest. After initial recognition, the Group recognises its share in 
the post-acquisition income and expenses of the associate in the statement of profit and loss with a corresponding increase (for 
income) or decrease (for losses) in the carrying value of the investment in the associate.

Dividends received by the Company from an associate are treated as a reduction in the carrying value of the associate (as its net 
assets have reduced by it giving the dividend) and income for the Group (as its net assets have increased by receiving the dividend).

The Group assesses the carrying value of associates for impairment at each reporting period end or at any other time where there 
is an indication that an impairment may exist. Where there is an indication of impairment of an investment, the Group assesses if an 
actual impairment loss exists by comparing the carrying value of the investment to its recoverable amount which is the lower of its 
fair value less cost to sell or its value in use.

Fair value less costs to sell is determined by reference to the proceeds that could be expected to be received should the interest in 
the associate be sold less the costs of doing so. Value-in-use is typically calculated by reference to the value of the discounted cash 
flows expected to be received from the associate.

Where there is a deficit of recoverable value as compared to the carrying value of the investment then an impairment loss is 
recognised in the consolidated statement of profit and loss in the amount of the calculated deficit. The carrying value of the 
investment in the associate is also reduced by a corresponding amount.

Acquisitions
The Group allocates the purchase consideration given in respect of the acquisition of a subsidiary to the assets acquired and 
liabilities assumed based on an assessment of their individual fair values at the date of acquisition. Any excess of the cost of the 
acquisition over the fair value of assets acquired and liabilities assumed in the business combination is recognised as goodwill.

The assessment of fair value is made by comparing the discounted value of the future cash flows expected to be generated from 
the CGU to which the goodwill has been allocated to the net book value of the assets and liabilities of that CGU including the 
allocated goodwill. Where a deficit of discounted cash flows compared to the carrying value of the CGU’s net assets and allocated 
goodwill exists, the goodwill is reduced to its recoverable amount with a corresponding amount recognised as an impairment 
charge in profit or loss. A corresponding reduction is made to the carrying value of goodwill and then to the net assets of the CGU if 
goodwill is insufficient to absorb the loss. Goodwill may also be tested for impairment under the fair value less costs to sell method 
where the recorded value of goodwill is compared to the market or value of the Company calculated by reference to its share price.

Any such impairment loss is recognised in profit and loss in the period in which it is identified. Impairment losses related to goodwill 
cannot be reversed in future years.

Transaction between entities within the Group
Transactions and balances between companies forming part of the Group together with any unrealised income and expenses 
arising from intra-group transactions are eliminated in the preparation of the consolidated financial statements of the Group.

Discontinued operations
A  discontinued  operation  is  a  component  of  the  Company’s  business  that  represents  a  separate  major  line  of  business  or 
geographical area of operations that has been disposed of or is held for sale. Classification as a discontinued operation occurs on 
actual disposal or earlier if the operation meets the criteria to be held for sale. When an operation is classified as a discontinued 
operation, the comparative consolidated statement of profit and loss is restated as if the operation had been discontinued from the 
start of the comparative period.

Disposal of subsidiaries
Transactions that result in the loss of control of a subsidiary are accounted for as disposals. The previously consolidated assets 
and liabilities and the carrying amount of any non-controlling interests in the subsidiary are derecognised. Any retained interest 
in the former subsidiary is recognised at its fair value at the date when control is lost. A gain or loss on disposal is recognised as 
the difference between the fair value of the consideration received together with the fair value adjustment made in respect of any 
retained interest in the subsidiary as offset by the carrying value of the assets and liabilities derecognised. Any gains or losses of the 
disposed entity that were previously recognised in other comprehensive income or loss and that require to be recycled to profit or 
loss also form part of the gain or loss on disposal.

(forming part of the consolidated historical financial information)

New standards, amendments and interpretations effective and adopted by the Group in 2021
No new standards became effective for the preparation of financial statements in accordance with IFRS for the year ended 31 
December 2021.

Amendments to existing standards previously issued by the IASB with effective dates during the year ended 31 December 2021 are 
summarised below. There was no effect on the Group’s consolidated financial statements for the year ended 31 December 2021 as 
a result of the adoption of these amendments.

Amendment to ‘IAS 37 Provisions, contingent liabilities and contingent assets’
An amendment to IAS 37 was published in May 2020 and requires the provision in respect of an onerous contract to also include 
an assessment of the indirect costs, such as production overhead or indirect labour, that are expected to be incurred in servicing 
a contract considered to be onerous.

The Company elected to early adopt the amendment as of 1 January 2020.

New standards and interpretations not yet adopted 
Certain new accounting standards and interpretations have been published that are not mandatory for 31 December 2021 reporting 
periods and have not been early adopted by the Company. These standards are not expected to have a material impact on the

Amendment to ‘IFRS 16 Leases’
IFRS 16 was issued by the IASB in January 2016 with an effective date of 1 January 2019 and introduced a single lease model 
requiring the recognition of right-of-use assets for all leases with a term greater than 12 months together with a corresponding lease 
liability. There is no longer any distinction between the accounting treatment for lease contracts that were previously classified as 
either operating leases or finance leases. IFRS 16 was adopted by the Group in its 2019 annual report and financial statements, as 
required by the standard.

On 28 May 2020, the IASB issued an amendment to the standard related to the treatment of rent concessions given by lessors in 
relation to COVID-19. The Group did not receive any rent concessions related to COVID-19 that would require consideration of the 
amendment to IFRS 16 and, accordingly, the amendment had no impact on the consolidated financial statements for the years 
ended 31 December 2020 or 2021.

Amendments to ‘IFRS 9 Financial Instruments’, ‘IAS 39 Financial Instruments: Recognition and Measurement’ and ‘IFRS 7 
Financial Instruments: Disclosures’
On 26 September 2019, the IASB issued ‘Interest Rate Benchmark Reform (Amendments to IFRS 9, IAS 39 and IFRS 7)’ related 
to potential effects of the IBOR reform on financial reporting related to hedging instruments. The amendment was effective for 
accounting periods starting on or after 1 January 2020. The Company does not currently use hedges or other purchased derivative 
instruments and therefore there is no impact on the Group financial statements for the year ended 31 December 2021.

A second amendment related to the IBOR reform was issued on 27 August 2020 with an effective date of 1 January 2021. This 
amendment is similarly not expected to have an impact on the financial reporting for the Group.

Critical accounting judgments and key sources of estimation uncertainty
The preparation of the financial statements in conformity with generally accepted accounting practice (GAAP) requires management 
to make estimates and judgments. Those estimates and judgments can affect the reported values for assets and liabilities as well as 
the disclosure of contingent assets and liabilities at the balance sheet date.

Management is also required to make estimates and judgments related to the reported amounts of revenues and expenses and 
related to the timing of the recognition of those revenues and expenses.

Judgments made and estimates applied are based on historical experience and other factors including management’s expectations 
of  future  events  that  are  considered  relevant.  Actual  results  may  differ  from  these  estimates.  The  estimates,  judgments  and 
underlying assumptions made are reviewed on an ongoing basis and specifically in the preparation of the interim and annual 
published financial information.

Revisions to accounting estimates are recognised in the period in which the estimate is revised and applied consistently in future 
periods subject to the ongoing reassessment of estimates.

Critical judgments for the year under review
Going concern
The directors are required to assess whether it is appropriate to prepare the financial statements on a going concern basis. In 
making this assessment the directors need to be satisfied that the Group can meet its obligations as they fall due and will remain 
cash-positive for a period of at least 12 months from the date of approval of the financial statements. Potential additional funding 
that is not yet committed at the date of approval of the financial statements cannot be anticipated in making the assessment of 
going concern.

The directors make their assessment based on a cash flow model prepared by management and based on its expectation of cash 
flows for the 18-month period from the date of approval of the financial statements. The extended period in the model provides 
additional comfort that the 12-month solvency requirement can be met when making the assessment of going concern.

In preparing the cash flow model, assumptions have been made regarding the timing of cash collection from customers based on 
the expected cash receipt under contracts that require milestone payments to be made by customers. The timing of the receipt of 
milestone payments may not always align with or precede the costs incurred by the Company in performing its obligations under 
a contract.

Downside sensitivities have been applied to the cash flows primarily related to the delay of customer receipts, from existing or 
expected sales contracts, and fluctuations in the price of input materials, particularly electrolyte. Refer to ‘Basis of preparation’ for 
details of the going concern analysis performed and the directors’ conclusions regarding going concern.

Notwithstanding the material uncertainty articulated in relation to the basis of preparation, the directors expect that the business 
will continue to be viable throughout the model period and, accordingly, the financial statements have been prepared on a going 
concern basis.

Revenue recognition
Sales contracts are assessed in accordance with the Group accounting policy for revenue recognition. The policy requires the 
separate performance obligations, or promises, under the contract to be identified. Revenue is recognised only when a distinct 
performance obligation under a contract is satisfied.

Some performance obligations are satisfied separately – for instance, the delivery of equipment, other obligations may be satisfied 
in conjunction with other contract promises or where a contract calls for equipment sold under the contract to be integrated into a 
larger project before formal acceptance is notified by the customer.

Where  the  ability  of  a  customer  to  benefit  from  a  product  or  service  is  dependent  on  the  satisfaction  of  other  performance 
obligations, more than one promise may need to be bundled together as a combined performance obligation that must be satisfied 
before the revenue related to each element can be recognised.

Identifying where equipment or, more likely, services are readily available from other providers is a key determinant as to whether 
a contract promise represents a separate performance obligation or if it should be bundled with other promises that, together, 
represent a single performance obligation.

The assessment of what constitutes a performance obligation can be complex and requires judgment. Revenue is only recognised 
for  each  performance  obligation  under  a  contract  when  that  performance  obligation,  bundled  or  otherwise,  is  satisfied.  The 
requirement to bundle combinations of goods and/or services together as a single performance obligation could delay the timing 
of revenue recognition where the separate promises comprising the performance obligation are delivered sequentially.

Key sources of estimation uncertainty for the year under review
Warranty provision
The Company provides time-limited standard warranties in its contracts for sale of battery systems. In addition, customers may elect 
to purchase separate, standalone extended warranties. Extended warranties are for periods greater than the standard warranties 
that are provided with the purchase of all battery systems.

Estimating the costs that may be incurred by the Company in servicing warranty agreements requires management to estimate 
the number of expected claims in relation to the total number of battery systems sold. In addition, an estimate of costs that the 
Company could expect to incur to remedy each warranty claim should also be made to determine the amount of the total provision 
that should be recorded for warranties.

59

Annual Report and Financial Statements 2021UK  /  US  /  CANADA  /  AUSTRALIAINTRODUCTIONSTRATEGIC REPORTGOVERNANCEFINANCIAL STATEMENTSInvinity Energy Systems plcNotes
(forming part of the consolidated historical financial information)

Provisions made in respect of expected warranty obligations are reassessed and remeasured where actual experience indicates 
the claim rate may be higher or lower than initially expected or where costs to remedy warranty claims differ from the assumptions 
used  in  calculating  the  provision.  The  release  of  an  over-provision  of  warranty  costs  results  in  other  operating  income  being 
recognised in the period whereas an additional provision for warranties results in a charge being recognised.

Refer to note 21, contract related balances.

Provision for legacy products
Management has elected to provide ongoing maintenance for certain legacy contracts not otherwise covered under warranty. 
Management has determined that it is necessary to provide for the costs of this ongoing maintenance or to provide for outright 
decommissioning.

Refer to note 21, contract related balances.

Provision for onerous contracts
A contract is onerous when the unavoidable costs of meeting the Company’s obligations under the contract are expected to 
be greater than the revenue earned under that contract. Previously, assessment of the unavoidable costs under a contract only 
required direct costs such as parts and labour to be considered. 

An amendment to ‘IAS 37 Provisions, contingent liabilities and contingent assets’ was published in May 2020 and requires the 
provision in respect of an onerous contract to also include an assessment of the indirect costs, such as production overhead or 
indirect labour, that are expected to be incurred in servicing a warranty claim. The Company elected to early adopt the amendment 
as of 1 January 2020.

The assessment of future costs is inherently subjective and requires the exercise of judgment in determining the appropriate 
amount of provision that may be required.

Refer to note 21, contract related balances.

Share based payments, warrants and employee options
The Company determines the fair value of share-based payments and employee options using a Black-Scholes methodology. 
Black-Scholes uses certain assumptions to determine fair value including measures of share price volatility, expected conversion or 
exercise rates and levels of employee retention, among others.

In estimating the value of future share price volatility, a key input of the Black-Scholes methodology, the Company uses historic 
data relating to its share price. As the short and long-term warrants are listed, and therefore can be publicly traded, this provides an 
alternative arms-length determination of fair value.

Operating segments
The Group is organised internally to report to the Executive Directors as a whole. The Executive Directors comprise the Chief 
Executive Officer, the Chief Commercial Officer and the Chief Financial Officer. The Executive Directors, as a group, have been 
determined, collectively, to prosecute the role of chief operating decision maker of the Group.

The chief operating decision maker is ultimately responsible for entity-wide resource allocation decisions, the evaluation of the 
financial, operating and ESG performance of the Group.

The Group’s activities have been determined to represent a single operating segment being the provision of vanadium flow batteries 
and ancillary services, principally comprising installation and integration services, and the provision of extended warranties for 
battery units sold.

3 Accounting policies
Revenue
The Group measures revenue based on the consideration specified in the contracts for sale with customers. Revenue is recognised 
when a performance obligation is satisfied by transferring control over a good or service to a customer. Control is usually considered 
to have transferred to a customer on delivery of equipment to the customer’s site of operations. Revenue excludes any taxes such 
as sales taxes, value added tax or other levies that are invoiced and collected on behalf of third parties, such as government tax 
authorities. 

60

Annual Report and Financial Statements 2021UK  /  US  /  CANADA  /  AUSTRALIA INTRODUCTIONSTRATEGIC REPORTGOVERNANCEFINANCIAL STATEMENTSInvinity Energy Systems plcNotes
(forming part of the consolidated historical financial information)

The Group generates revenue from the sale of battery storage systems and related hardware and services. The main portion of 
sales is derived from contractual arrangements with customers that have multiple elements (or performance obligations), those 
elements  usually  being  the  sale  of  battery  systems,  system  related  options,  installation,  and  extended  warranties.  The  sales 
contracts do not include a general right of return. 

For contracts that contain multiple elements or promises, the Group accounts for individual goods and services separately if they 
are distinct. A product or service is distinct if it is separately identifiable from other items in the agreement and where a customer 
can benefit from the good or service on its own or together with other resources that are readily available.

The consideration paid for each performance obligation is typically fixed. A significant portion of the aggregate payment due 
under a contract for sale is normally due before delivery or completion of the service. The total consideration under the contract 
is allocated between the distinct performance obligations contained in the contract based on their stand-alone selling prices. The 
stand-alone selling price is estimated using an adjusted market assessment approach that looks to industry benchmarks or pricing 
surveys for certain standalone products or services.

In addition, under the terms of its contracts for sale, the Group may be responsible for delivering battery systems to its customers. 
When this is the case, the Group will invoice the relevant customer for, and will recognise as revenue, any charges incurred together 
with any associated handling costs. The related costs incurred by the Group for shipping and handling services are recognised as 
cost of sales concurrent with the recognition of the associated revenue.

Grant income
Government and other grants received are recognised in the consolidated statement of profit and loss in the period that the related 
expenditure is incurred. Grant income received in respect of costs incurred is presented net within the associated cost category. 
Capital grants are similarly netted against the relevant asset acquired or constructed.

Grant income received in advance of the associated expenditure is presented as deferred income within contract liabilities and 
released to profit and loss as the associated expenditure is incurred. Grant income receivable is presented as accrued income within 
contract assets until such time as it can be claimed or is received.

Finance income and costs
Finance income comprises interest on cash deposits, foreign currency gains and the unwind of discount on any assets that are 
carried at amortised cost. Interest income is recognised as it accrues using the effective interest rate method.

Finance costs include foreign currency losses and the unwind of the discount on any liabilities held at amortised cost, such as lease 
liabilities arising from lease contracts.

Employee benefits
Short-term benefits
Benefits provided to employees that are short-term in nature are recognised as expenses in the statement of profit and loss as the 
related service is provided. The principal short-term benefits given to employees are salaries, associated holiday pay and other 
periodic benefits such as healthcare and pension contributions made by the Company for the benefit of the employee. A liability is 
recognised for the amount expected to be paid under short-term cash bonus plans if there is either a present legal or constructive 
obligation to pay the amount and the amount can be reliably estimated.

Share based payments
The Group operates equity-settled share-based compensation plans, under which it compensates employees for services rendered 
through the issue of equity instruments, deferred share awards or options to subscribe for ordinary shares of the Company. The fair 
value of the employee services received in exchange for the grant of the equity instruments, shares or options is recognised as an 
expense. The total amount to be expensed is determined by reference to the fair value of the options granted:

 including any market conditions (for example, the Company’s share price)
 excluding the impact of any service and non-market performance vesting conditions (for example, profitability, sales growth 
targets, and the requirement to remain as an employee of the Group over a specified period)
 including the impact of any non-vesting conditions (for example, the requirement for an employee to save)

Non-market  performance  and  service  conditions  are  included  in  the  assumptions  regarding  the  number  of  options  that  are 
expected to vest. The total expense is recognised over the vesting period, which is the period over which all the specified vesting 
conditions are to be satisfied.

Notes
(forming part of the consolidated historical financial information)

In some circumstances, employees may provide services in advance of the grant date and therefore the grant date fair value is 
estimated for the purposes of recognising the expense during the period between service commencement and the grant date.

At the end of each reporting period, the Group revises its estimates of the number of options that are expected to vest based on 
the non-market vesting conditions. It recognises the impact of the revision to original estimates, if any, in the consolidated statement 
of profit and loss, with a corresponding adjustment to equity. 

Any social security contributions payable in connection with the grant of the share options is considered an integral part of the grant 
itself, and the charge will be treated as a cash-settled transaction.

Taxes
The total tax charge or credit recognised in the statement of profit and loss comprises both current and deferred taxes.

Taxation is recognised in the consolidated statement of profit and loss except to the extent that it relates to a business combination 
or items recognised directly in equity or other comprehensive income.

Current tax
The current tax charge is based on the taxable profit for the year. Taxable profit or loss is different from the profit or loss reported 
in the statement of profit and loss as it excludes items of income and/or expense that are taxable or deductible in other years 
(temporary differences) and it further excludes items that are never taxable nor deductible (permanent differences).

Deferred tax
Deferred tax is the tax that is expected to be payable or recoverable on differences between the carrying value of assets and 
liabilities in the financial statements and the corresponding value of those assets and liabilities used to calculate taxable profit or loss.

Deferred tax  assets are recognised as deductible temporary differences  only  where it  is  probable  that taxable profits will be 
generated against which the carrying value of the deferred tax asset can be recovered. Deductible temporary differences exist 
where there is a difference in the timing of the recognition of an item of income or expense between the statement of profit and 
loss and the calculation of taxable profit or loss (a temporary difference).

Deferred tax assets and liabilities are recognised using the liability method for all taxable temporary differences, except in respect 
of taxable temporary differences associated with investments in subsidiaries, associates and interests in joint operations. Where 
the timing of the reversal of temporary difference arising from such investment related assets and liabilities can be controlled and 
it is probable that the temporary difference will not reverse in the foreseeable future then the Group does not recognise deferred 
tax liabilities on these items. 

A deferred tax asset or liability is not recognised if a temporary difference arises on initial recognition of an asset or liability in a 
transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable 
profit or loss. 

Current and deferred tax is calculated using tax rates and laws that have been enacted or substantively enacted at the balance 
sheet date.

Earnings per share
The Group presents basic and diluted earnings per share (“EPS”) data for its ordinary shares. Basic EPS is calculated by dividing the 
profit or loss attributable to ordinary shareholders of the Company by the weighted average number of ordinary shares outstanding 
during the year.

Diluted EPS is determined by adjusting the weighted average number of ordinary shares outstanding used in the EPS calculation to 
include all potentially dilutive ordinary shares, which, in the case of the Company, represents additional shares that could be issued 
in relation to ‘in-the-money’ convertible notes, warrants or share options.

The effects of anti-dilutive potential ordinary shares are ignored in calculating diluted EPS. Anti-dilution is when an increase in 
earnings per share or a reduction in loss per share would result from the exercise of such options, warrants or convertible instruments.

Intangible assets
Goodwill
The Group allocates the fair value of the purchase consideration on the acquisition of a subsidiary to the assets acquired and 
liabilities assumed based on an assessment of fair value at the acquisition date. Any excess of purchase consideration is recognised 
as goodwill. Where goodwill is recognised, it is allocated to the cash generating units (CGUs) in a systematic manner reflective of 
how the Group expects to recover the value of the goodwill.

Goodwill arising is recognised as an intangible asset in the balance sheet and is subject to annual reviews for impairment. Goodwill 
is written off where circumstances indicate that the recoverable amount of the underlying CGU may no longer support the carrying 
value of the goodwill. An impairment charge is recognised in the statement of profit and loss for the period in which it is determined 
the goodwill is no longer recoverable. Impairment losses related to goodwill cannot be reversed in future periods.

In testing for impairment, goodwill recognised on business combinations is allocated to the Group of CGUs representing the lowest 
level at which it will be monitored. Because the Group has been determined to consist of a single business unit, the carrying value 
of goodwill is tested for impairment based on the recoverable value of the Group as a whole.

The recoverable amount of a CGU or a group of CGUs is based on the higher of its assessed fair value less costs of disposal or 
its value-in-use. Value-in-use is calculated by reference to the expected future cash flows from the CGU, after discounting to take 
account of the time value of money. Fair value less costs to sell can be based on a similar cash flow measure adjusted for disposal 
costs or can be estimated by reference to similar comparable reference transactions.

Because the Company is listed, fair value can also be assessed by reference to the Company’s market capitalisation. Where cash 
flows are used, they are risk weighted to reflect an assessment of future commercial success.

The key assumptions in assessing cash flows relate to the ability of the Company to develop existing markets and applications and 
to establish new markets and applications for the sale and use of its battery systems. Prospective cash flows are also sensitive to 
the Company’s ability to realise economies of scale as market penetration grows.

Internally generated intangible assets – research and development costs
Research
Expenditure on research activities is recognised as an expense in the period in which it is incurred. Research activities are aimed 
at creating new knowledge or the use of existing knowledge in new or creative ways to generate new concepts. Research activity 
does not typically have a defined commercial objective at the outset. 

Development
Where projects evolve toward commerciality or are related to a specific commercial objective they are assessed to determine 
whether the activity constitutes development that is associated with a commercial objective or practical application. 

The  associated  costs  represent  development  costs  and  can  be  capitalised  if,  and  only  if,  the  following  conditions  can  be 
demonstrated:

   the technical feasibility of completing the intangible asset so that it can be made available for use or sale;
   the intention to complete the intangible asset for use or sale;

 the availability of adequate technical, financial and other resources to complete the development and to use or sell it;

   an asset is created that can be separately identified for use or sale;

it is probable that the asset created will generate future economic benefits; and

   the development cost of the asset can be measured reliably.

Development work undertaken by the Group typically relates to the refinement of design, materials selection, construction 
techniques,  firmware  and  control  systems  to  enhance  battery  system  performance  over  successive  generations.  Where 
development costs are capitalised, they are amortised over the expected period to the introduction of the next generation of 
battery system. 

Amortisation is recorded over that period on a straight-line basis with the corresponding amortisation charge recognised in the 
statement of profit and loss as a component of administrative expenses.

Four years has historically been the typical cycle time between successive generations of battery system design.

Other intangible assets
Intangible assets other than goodwill that are acquired by the Group are stated at their historical cost of acquisition less accumulated 
amortisation and any impairment losses. 

Software and purchased domain names
Third-party software is initially capitalised at its cost of purchase. Amortisation is charged to administrative expenses over the 
expected useful life of the software which has been assessed as three years from the date of acquisition.

Acquired domain names are initially capitalised at cost of purchase. Amortisation is charged to administrative expenses over the 
expected useful life of the domain name which has been assessed as ten years from the date of acquisition.

Patents and certifications
Patent rights and certifications are initially capitalised at the cost of applying for relevant patent rights and other protections, and 
certifications. Amortisation is charged to administrative expenses over the expected useful life of the patents and certifications 
which has been assessed as five years from the date of acquisition.

Property, plant and equipment
Items of property, plant and equipment are stated at historical cost less accumulated depreciation and any impairment losses. 
Historical cost includes expenditure that is directly attributable to the acquisition of the items. Subsequent expenditure is only 
included in the asset’s carrying amount or recognised as a separate asset, as appropriate, when it is probable that future economic 
benefits associated with that item will flow to the Group.

Costs that do not enhance the value of an asset such as repair and maintenance costs are charged to the statement of profit and 
loss in the period in which they are incurred.

Depreciation  is  charged  to  write  off  the  cost  of  assets  over  their  estimated  useful  lives  on  a  straight-line  basis.  Depreciation 
commences on the date the asset is brought into use. Work-in-progress assets are not depreciated until they are brought into use 
and transferred to the appropriate category of property, plant and equipment.

Estimated useful lives for property, plant and equipment are:

Category 

Computer and office equipment 
Leasehold improvements 

Vehicles 

Manufacturing equipment and tooling 

R&D Equipment 

Software and purchased domain names 

Patents and certifications

Depreciation methods, useful lives and residual values of assets are reviewed, and adjusted prospectively as appropriate, at each 
reporting date.

Where an asset is disposed of, the corresponding gain or loss on disposal is determined by comparing the sales proceeds received 
with the carrying amount of that asset at the date of disposal. Gains or losses on disposal of fixed assets are included within other 
items of operating income and expense in the statement of profit and loss.

Impairment of tangible and intangible assets 
The Group reviews the carrying values of its tangible and intangible assets, other than goodwill, at each balance sheet date to 
determine if any indicators exist that could mean those assets are impaired. Where an indicator of impairment exists the recoverable 
amount of the relevant asset (or CGU) is estimated to determine the amount of any potential impairment loss.

Recoverable amounts are determined using a discounted cash flow model related to each asset or CGU being assessed. The

Notes
(forming part of the consolidated historical financial information)

discount rate applied to the cash flows in the model is a pre-tax discount rate that reflects market assessment of the time value of 
money and risks specific to the Company or the groups of assets being considered.

If the recoverable value estimated in the cash flow model for a specific asset (or CGU) is lower than the carrying value, then the 
carrying value of the asset is reduced to its estimated recoverable value with a corresponding charge immediately recognised in 
the statement of profit and loss.

Where the condition that gave rise to an impairment loss reverses in a subsequent period, the impairment loss is similarly reversed 
and the carrying value of the asset increased to the revised estimate of its recoverable value. The carrying value of an asset 
immediately following the reversal of an impairment cannot exceed the carrying value that the asset would have had if the original 
impairment had not been made and the asset was depreciated as normal.

A reversal of an impairment loss is recognised immediately in profit or loss. 

The value of any impairment (or reversal of impairment) of an asset is recorded in the same financial statement line item where 
depreciation or amortisation of the asset would normally be shown.

Where it is impractical to meaningfully assess recoverable amount using a discounted cash flow model, for instance where near 
term cash flows are low or negative, an assessment of the fair value adjusted for the costs that would be incurred in the disposal 
of an asset or operation is used. This is typically the case for development stage assets, operations or associated intangible assets 
(including goodwill) where the underlying products or technologies have not yet been commercialised.

Provisions
Provisions are established when the Group has a present legal or constructive obligation because of past events, it is probable that 
an outflow of resources will be required to settle the obligation and the amount of that outflow can be reliably estimated.

Provisions are measured at the present value of the expenditures that are expected to be incurred in settling the obligation using a 
pre-tax discount rate that reflects current market assessment of the time value of money and the risks related to the obligation. The 
initial recognition of a provision results in a corresponding charge to profit or loss.

The increase in a provision as the discount rate unwinds due to the passage of time, is recognised in the statement of profit and loss 
as other items of operating income and expense.

Leases
Group entities only participate in lease contracts as the lessee. Lease contracts typically relate to vehicles and facilities.

On inception of a contract, the Group assesses whether it contains a lease. A contract is, or contains, a lease if it conveys the right to 
control the use of an identified asset for a period of time in exchange for consideration. The right to control the use of an identified 
asset is determined based on whether the Group has the right to obtain substantially all the economic benefits from the use of the 
asset throughout the period of use, and if the Group has the right to direct the use of the asset.

Obligations  under  a  lease  are  recognised  as  a  liability  with  a  corresponding  right-of-use  asset,  these  are  recognised  at  the 
commencement date of the lease.

The lease liability is initially measured at the present value of the lease payments that have not yet been paid at the inception of the 
lease, discounted using the interest rate implicit in the lease contract. Where the interest rate implicit in the lease contract cannot be 
readily determined, the Group’s incremental borrowing rate is used.

Variable lease payments that do not depend on an index or rate are not included in the measurement of the lease liability. The lease 
liability is measured at amortised cost using the effective interest rate method.

The lease liability is subsequently measured at amortised cost using the effective interest method. It is remeasured when: 

   there is a change in future lease payments arising from a change in an index or rate;
   there is a change in the Group’s estimate of the amount expected to be payable under a residual value guarantee; or 
   the Group changes its assessment of whether it will exercise a purchase, extension or termination option.

65

Annual Report and Financial Statements 2021UK  /  US  /  CANADA  /  AUSTRALIAINTRODUCTIONSTRATEGIC REPORTGOVERNANCEFINANCIAL STATEMENTSInvinity Energy Systems plcNotes
(forming part of the consolidated historical financial information)

When a lease liability is remeasured under one of these scenarios, a corresponding adjustment is made to the carrying value of the 
right-of-use asset or in profit and loss when the carrying amount of the asset has already been reduced to zero.

The corresponding right-of-use asset is initially measured at cost, which comprises the initial amount of the lease liability plus any 
lease payments made at or before the commencement date, any initial direct costs incurred and an estimate of the costs required 
to remove or restore the underlying asset, less any lease incentives received. The right-of-use asset is amortised over the shorter 
of the asset’s useful life and the lease term on a straight-line basis.

The Group has elected not to recognise right-of-use assets and corresponding lease liabilities for short-term leases, those existing 
leases with a remaining lease term of less than 12 months at 1 January 2021 and leases related to low value assets with an annual 
lease cost of £3,500 or less.

The Group recognises these lease payments as an expense on a straight-line basis over the lease term.

Inventory
Inventory is stated at the lower of cost and net realisable value. Cost comprises direct materials and, where applicable, direct 
labour costs and those overheads that have been incurred in bringing the inventories to their current location and condition. Cost is 
calculated using the first-in, first-out method.

Net realisable value is calculated as the estimated selling price for an item of inventory less estimated costs of completion and the 
costs that would be incurred in the marketing, selling and distribution of an item of inventory.

Prepaid inventory
Prepaid inventory is recognised on inventory payments where physical delivery of that inventory has not yet been taken by the 
Group and is stated at the lower of cost and net realisable value.

Financial instruments
Financial assets and liabilities are recognised by the Group and recorded in the statement of financial position when the Group is 
contractually bound to the terms of the financial instrument. Financial assets and liabilities are derecognised when the Group is no 
longer bound by the terms of the financial instrument through settlement or expiry.

Financial assets
The classification of financial assets to which the Group is a party is determined by the nature of the underlying financial instrument 
and the characteristics of the contractual cash flows expected to be received under the terms of instrument.

Financial assets are not reclassified after their initial recognition unless there is a contractual change in the nature of the cash flows 
under the instrument or the business purpose of the instrument has changed.

A financial asset is recorded at amortised cost where it is expected to be held to maturity and the objective of the Group is to collect the 
contractual cash flows under the financial instrument based on specified contractual terms, including the timing of receipt of cash flows.

Financial assets that the Group is party to are classified and measured as follows:

Trade receivables and accrued income 
Other current assets 
Contract assets 
Cash and cash equivalents

Amortised cost
On initial recognition, the Group measures amortised cost for financial assets based on the fair value of each financial asset together 
with any transaction costs that are directly attributable to the financial asset.

After initial recognition, amortised cost is measured for each financial asset held using the effective interest rate method less any 
impairment loss identified. Interest income is recognised for all financial assets, other than those that are classified as short-term, by 
applying the effective interest rate for the instrument. Interest income on short-term financial assets is not considered to be material. 
Short-term financial instruments are determined as those that have contractual terms of 12-months or less at inception.

Interest income, foreign exchange gains and losses, impairment, and any gain or loss on derecognition are recognised in profit or loss.

Impairment of financial assets
A loss allowance for financial assets is determined based on the lifetime expected credit losses for financial assets. Lifetime expected 
credit losses are estimated based on factors including the Group’s experience of collection, the number and value of delayed 
payments past the average credit periods across the Group’s financial assets. The Group will also consider factors such as changes 
in national or local economic conditions that correlate with default on receivables and financial difficulties being experienced by the 
counterparty.

Financial  assets  are  impaired  in  full  and  a  corresponding  charge  is  recognised  in  profit  or  loss  where  there  is  no  reasonable 
expectation of recovery.

Financial liabilities
The classification of financial liabilities is determined at initial recognition. Financial liabilities are classified and measured as follows:

Financial liability 

Trade and other payables 
Borrowings 
Lease liabilities 

Measurement basis

Amortised cost 
Amortised cost 
Amortised cost

Amortised cost
At initial recognition, the Group measures financial liabilities at amortised cost using the fair value of the underlying instrument less 
transaction costs directly attributable to the acquisition of the financial liability.

Derecognition of financial liabilities
The Group derecognises financial liabilities when the Groups obligations under the relevant instrument are discharged, expired or 
cancelled.

Cash and cash equivalents
Cash and cash equivalents include cash on hand, deposits held with financial institutions that can be called on demand together with 
other short-term, highly liquid investments with maturities of three months or less and are readily convertible to known amounts of 
cash.

Equity instruments
Instruments are classified as equity instruments if the substance of the relative contract arrangements evidences a residual interest 
in the assets of the Group after deducting all of its liabilities. Equity instruments issued by the Company are recorded as proceeds 
received, net of direct issue costs not charged to income.

Offsetting
A financial asset and a financial liability are offset and the net amount presented in the statement of financial position when, and 
only when, the Group:

1.  has a legally enforceable right to set off the recognised amounts; and
2. intends either to settle on a net basis, or to realise the asset and settle the liability simultaneously.

The Group maintains its principal production and assembly facilities in Bathgate, Scotland and Vancouver, Canada. These facilities 
include office space for design, sales and administrative teams. The Group also has offices, operations and management based in 
London, England and Oakland, California.

The Group does not consider that the locations of its operations constitute geographic segments as they are managed centrally 
by the executive management team. The location of the manufacturing plants and business development activity is a function of 
time-zone when servicing customers both pre-sale and during product delivery. The geographic location of offices, facilities and 
management is not related to distinct markets or customer characteristics at the present time.

Significant customers and concentration of revenue
Revenue from contracts with customers was derived from two (2020: four) customers who each accounted for more than 10% of 
total revenue as follows:

9 Share based payments
Since its incorporation, the Company has operated various share-based incentive plans. The purpose of each of the schemes has 
been to incentivise directors and employees related to improving company performance and building shareholder value. 

Set out below is a summary of the option awards in issue at 31 December 2021. The comparative figures for both number of awards 
outstanding at the end of 2020 and their respective exercise prices have been adjusted to reflect the 50:1 share consolidation that 
took place on 1 April 2020 (as rounded down to the nearest whole share).

*  Prior year comparatives have been restated to account for late notification of lapses and the mis-categorisation of certain awards. The net change in the reported prior year comparatives is 

a reduction of 3,152 share options.

A total of 332,481 options were exercised during the year with a weighted average exercise price of 15.33p per share.

The grant-date fair value of share options issued is calculated using a Black-Scholes methodology at the date of grant. Key inputs 
to the model include the share price at the date of grant, the option exercise price, the term of the award, share price volatility, the 
risk-free interest rate (by reference to government bond yields) and the expected dividend yield rate, which has historically been 
and continues to be zero, reflective of the development-stage nature of the Company.

The Long-term Incentive Plan, Camco 2006 Executive Share Plan and the redT 2015 Plan are now closed. No further options option 
awards will be made under either of these plans.

Plans with non-standard performance conditions
Long-term incentive plan (LTIP) 
The LTIP for directors and employees was approved by the board in 2008 and entitled directors and employees to receive equity 
settled payments annually based on the achievement of certain market and non-market performance conditions.

The LTIP is now closed. At the end of the year, there were 15,000 (2020: 15,000) options vested and exercisable at €0.5 per share 
under the LTIP.

CAMCO 2006 executive share plan (the plan)
The plan was established in 2017 to make awards of shares up to an aggregate of 10% of the share capital of the Company over a 
period of ten years.

The plan is now closed. At the end of the year there were 68,127 (2020: 68,127) options that had vested and were exercisable at 
€0.50 per share.

2018 plan
Options with non-standard performance conditions were also issued under the 2018 plan. At the end of the year 70,000 (2020: 
70,000) options under the 2018 plan had vested and are exercisable at 400p per share.

Plans with standard performance conditions
The primary share plan that remains outstanding at 31 December 2021 is the 2018 plan. The 2018 plan was adopted by the board on 
14 May 2018 and introduced HMRC scheme rules related to certain non-taxable option grants. The plan contains provision to issue 
options as CSOP, EMI or unapproved awards.

In the year ended 31 December 2020 the board approved the expansion of awards to be made under the 2018 plan with grants expected 
to be made more frequently going forward and to a potentially wider group of employees. The intention of the increase in frequency 
and quantity of employee share options granted was to incentivise and to better align employee compensation with shareholder return.

Options issued to legacy Avalon employees at the merger date
Following the merger transaction, 1,432,000 options were granted to legacy Avalon employees to replace options held by them in 
the former Avalon employee share plan. A total of 2,670,492 options are vested and exercisable under the 2018 plan at 31 December 
2021 with a further 4,269,588 unvested share options outstanding.

Parallel options issued
In addition, certain legacy redT options were reissued as they were considered by the board to be sufficiently ‘out-of-the-money’ 
such that they no longer provided a performance incentive to the holders of the options. As a mechanism to adjust the terms of 
the unfavourable options, new parallel options were issued on a one-for-one basis with the same terms as the original awards 
excepting that they were issued with a lower exercise price.

Both the original and parallel option schemes remain in existence. However, the exercise by an employee of a single option from either 
pool (original or parallel) allocated to them will cause the equivalent value in the other pool to be forfeited. Accordingly, the number of 
options disclosed above has been adjusted to remove the number of options that is equivalent to the number of parallel options issued.

Other options
On 10 May 2021, the Company granted an option for 8,672,273 shares to Gamesa Electric S.A. Unipersonal (GaE), a wholly-owned 
subsidiary of Siemens Gamesa Renewable Energy S.A. The options were granted to GaE in consideration of its entering into a joint 
development and commercialisation agreement with Invinity Energy Nexus Limited, a wholly-owned subsidiary of the Company. 

The exercise price of the options is 175 pence and upon exercise of those options then for as long as GaE holds at least 5% of the 
issued share capital of the Company it shall be entitled, subject to certain conditions, to nominate one non-executive director to the 
board of the Company.

Warrants issued in the period
Short-term and long-term equity warrants
In December 2021, the Company issued 14,464,571 ‘placing units’ comprised of one share, one short-term warrant and one long-
term warrant.

Each short-term warrant gives the holder the right to subscribe for one new Ordinary Share at a price of 150 pence per Ordinary 
Share at any time from Second Admission until 15 September 2022. Each long-term warrant gives the holder the right to subscribe 
for one new Ordinary Share at a price of 225 pence per Ordinary Share at any time from Second Admission until 16 December 2024.

The warrants were admitted to trading on the Aquis Stock Exchange (AQSE) on 9 March 2022. There was no adjustment to the 
issue price in respect of the attached warrants and they have been deemed to have no fair value based on the price at which they 
are currently being quoted.

All operational activity in the years ended 31 December 2020 and 2021 relate to continuing operations.

Earnings per share in respect of the year ended 31 December 2020 have been restated to give effect to the 50:1 share consolidation 
that took place in 2020 and to aid comparability.

Additional potential shares used in the calculation of diluted earnings per share primarily relate to potential shares outstanding at 31 
December 2021 that may be issued in satisfaction of ‘in-the-money’ employee share options. Potentially dilutive shares related to 
outstanding warrants to subscribe for ordinary shares in the Company are also included in calculating diluted earnings per share. 

Where additional potential shares have an anti-dilutive impact on the calculation of loss per share calculation, such potential shares 
are excluded from the weighted average number of shares used in the calculation.

Goodwill
All goodwill is tested annually for impairment. At 31 December 2021, goodwill was tested for impairment using a fair value less costs 
of disposal methodology by reference to the Company’s quoted market capitalisation using the price of 92.5 pence per share 
at that date. No impairment loss was identified in relation to goodwill. The closing share price on 22 June 2022 was 53p, giving a 
market capitalisation of £61.5m which may indicate a potential impairment.

Patents and certifications
There have been no events or circumstances that would indicate that the carrying value of patents and certifications may be 
impaired at 31 December 2021.

1  A lease on a right-of-use asset in Canada has been curtailed in 2021, with the termination date changing from June 2027 to June 2023. There is a corresponding decrease in the 

outstanding lease creditor and a gain on curtailment recognised in the consolidated statement of profit and loss.

Right-of-use assets relate to buildings, vehicles and equipment held under leases with third-party lessors. A right-of-use asset 
represents the Company’s right to use a leased asset over the term of the lease. The Company’s rights to use specific buildings, 
items of equipment or specific vehicles under lease arrangements represent assets to the Group.

The lease payments are discounted using the interest rate implicit in the lease. If that rate cannot be readily determined, which is 
generally the case for leases in the Group, the lessee’s incremental borrowing rate is used, being the rate that the individual lessee 
would have to pay to borrow the funds necessary to obtain an asset of similar value to the right-of-use asset in a similar economic 
environment with similar terms, security and conditions.

To determine the incremental borrowing rate, the Group: 

 where possible, uses recent third-party financing received by the individual lessee as a starting point, adjusted to reflect changes 
in financing conditions since third party financing was received;
 uses a build-up approach that starts with a risk-free interest rate adjusted for credit risk for leases;
 held by the Group, which does not have recent third party financing; and
 makes adjustments specific to the lease, e.g. term, country, currency and security.

The Company’s subsidiaries carry on business in other tax regimes where the corporation tax rate is not zero. At 31 December 2021, 
the Group had the following tax losses carried forward available for use in future periods:

Under current tax legislation tax losses in the United Kingdom and Ireland can be carried forward indefinitely and be offset against 
future profits arising from the same activities at the tax rate prevailing at that time. There is a portion of the tax losses in the United 
States of America that will begin to expire in 2035, whereas the majority can be carried forward indefinitely. The tax losses in 
Canada can be carried forward 20 years. Tax losses in Canada will begin to expire in 2025.

Due to the uncertainty regarding the timing and extent of future profits within these subsidiaries, no deferred tax assets have been 
recognised in respect of these tax losses. Deferred tax is also not recognised on the timing differences between accounting and tax 
treatment in these subsidiaries given the offsetting tax losses on which no deferred tax has been recognised.

In March 2021, the UK Government announced that the rate of Corporation Tax will increase from 19% to 25% on profits of over 
£250,000. Profits below £50,000 will continue to be chargeable to Corporation Tax at 19% and profits between the two thresholds 
charged at the marginal rate of 26.5%. In computing the UK deferred tax asset, management has assumed that as neither the 
deferred  tax  assets  nor  the  deferred  tax  liabilities  will  crystallise  in  the  immediate  future,  then  calculations  based  on  19%  are 
appropriate.

Prepaid inventory is recognised on inventory payments where physical delivery of that inventory has not yet been taken by 
the Group and is stated at the lower of cost and net realisable value.

21 Contract related balances
The Group has recognised the following assets and liabilities related to revenue from contracts with customers that are in progress 
at the respective year-ends:

Amounts due from customer contracts included in trade receivables 
Contract assets (accrued income for work done not yet invoiced) 
Contract liabilities (deferred revenue related to advances on customer contracts)

(2,644)

(2,606)

The amount of revenue recognised in the year that was included in contract liabilities at the end of the prior year was £2,231,000 
(2020: £nil). 

The aggregate position on customer contracts included in the statement of financial position will change according to the number 
and size of contracts in progress at a given year-end as well as the status of payment milestones made by customers toward 
servicing those contracts. The Group structures payment milestones in its customer contracts to cover upfront expenditure for 
parts and materials and other working capital requirements associated with the delivery of promises under customer contracts to 
better manage group cash flow.

The timing of revenue recognition is based on the satisfaction of individual performance obligations within a contract and is not 
based on the timing of advances received. Customer advances are recognised as contract liabilities in the statement of financial 
position and are released to income progressively as individual performance obligations are met. The difference in timing between 
the receipt of contract advances and the timing of the satisfaction of performance obligations for revenue recognition can cause 
values to remain in deferred income. The amount of such deferrals is related to both the overall size of the underlying contract and 
the planned pace of delivery in the related work schedule. This is expected to occur where satisfaction of performance obligations 
is evidenced by customer acceptance of the good or service that is the subject of the performance obligation.

Warranty provision
The warranty provision represents management’s best estimate of the costs anticipated to be incurred related to warranty claims, 
both current and future, from customers in respect of goods and services sold that remain within their warranty period. The estimate 
of future warranty costs is updated periodically based on the Company’s actual experience of warranty claims from customers.

The element of the provision related to potential future claims is based on management’s experience and is judgmental in nature. 
As for any product warranty, there is an inherent uncertainty around the likelihood and timing of a fault occurring that would cause 
further work to be undertaken or the replacement of equipment parts.

A standard warranty of up to two years from the date of commissioning is provided to all customers on goods and services sold 
and is included in the original cost of the product. Customers are also able to purchase extended warranties that extend the 
warranty period for up to a total of ten years.

Provision for legacy products
Where it is considered of commercial value, management has elected to provide ongoing maintenance for certain legacy products 
not otherwise covered under warranty. Management has determined that it is necessary to provide for the costs of this ongoing 
maintenance or to provide for outright decommissioning. The prior year presentation has been re-stated to reflect this.

Provisions in respect of legacy products are expected to unwind over the next two years when maintenance is either terminated 
or the products are decommissioned.

Provision for contract losses
A provision is established for contract losses when it becomes known that a customer contract has become onerous. A contract is onerous 
when the unavoidable costs of fulfilling the Group’s obligations under a contract are greater than the revenue that will be earned from it.

The unavoidable costs of fulfilling contract obligations will include both direct and indirect costs. 

The creation of an additional provision is recognised immediately in profit and loss. The provision is used to offset subsequent costs 
incurred as the contract moves to completion.

In determining the amount to be provided, management has evaluated the likelihood of input costs continuing to rise against a 
backdrop of inflation and instability due to current macro-economic factors such as the global response to Covid-19, the increasing 
price of oil feeding through to production and shipping costs and continuing supply chain issues.

Provisions in respect of contract losses relate to contracts which are expected to be delivered in 2022 and will therefore unwind 
during that year.

All trade and other receivables relate to receivables arising from contracts with customers.

Trade receivables are amounts due from customers for sales of vanadium flow battery systems in the ordinary course of business. 
Trade receivables do not bear interest and generally have 30-day payment terms and therefore are all classified as current.

The actual credit loss over 2021 was determined to be 0% of total sales (2020: 0%). No allowance for potential credit loses has been 
recognised in either period presented.

(forming part of the consolidated historical financial information)

In the year ended 31 December 2021, Yorkville Advisors exercised 909,090 warrants at 107 pence to subscribe for ordinary shares 
in the Company. A total of 909,090 new ordinary shares were issued to Yorkville Advisors in return for total subscription proceeds 
of £972,726.

The holders of ordinary shares are entitled to receive dividends as declared from time to time and are entitled to one vote per share 
at meetings of the Company.

Share-based payment reserve
The share-based payment reserve comprises the equity component of the Company’s share-based payments charges.

Currency translation reserve
The translation reserve comprises foreign currency differences arising from the translation of the financial statements of foreign 
operations.

Other reserve
Other reserve comprises the portion of the consideration paid for redT energy Holdings (Ireland) Limited’s minority interests over 
the fair value of the shares purchased.

27 Financial assets and liabilities
All financial assets are held at amortised cost. There were no financial assets measured at fair value through other comprehensive 
income nor through profit and loss in either period presented.

The maximum exposure to credit risk at the end of the reporting period is the carrying amount of each class of financial asset presented 
above. The carrying value of the financial assets approximate their fair values due to the short-term maturities of these instruments.

The Group does not currently use derivative instruments for managing financial risk. All financial liabilities are held at amortised cost.

Recognised fair value measurements
The Group uses the following hierarchy for determining and disclosing the fair value of financial instruments by valuation technique:

Level 1:  

 The fair value of financial instruments traded in active markets (such as publicly traded derivatives, and trading 
securities) is based on quoted market prices at the end of the reporting period.

The  battery  systems  manufactured  by  the  Company  use  vanadium  metal  as  a  key  component  in  the 
electrolyte. Vanadium is an actively traded commodity for which quoted market prices are available.

The Company does not currently hold inventories of vanadium. Vanadium purchased from third parties is 
solely for the use in electrolyte and open purchase contracts are not accounted for as derivatives.

Level 2: 

 The fair value of financial instruments that are not traded in an active market (for example, over-the-counter 
derivatives) is determined using valuation techniques that maximise the use of observable market data and 
rely as little as possible on entity-specific estimates. If all significant inputs required to fair value instrument are 
observable, the instrument is included in Level 2. The Group did not hold any financial assets or liabilities that 
were required to be valued using level 2 inputs (2020: none)

Level 3: 

 If one or more of the significant inputs is not based on observable market data the instrument is included in 
Level 3. 

The Group did not hold any financial assets or liabilities that were required to be valued using level 3 inputs 
at 31 December 2021. At 31 December 2020, the warrant deed remained outstanding. No other financial 
instruments were outstanding at the period end that required to be valued using a methodology that uses 
Level 1, 2 or 3 inputs.

Market risk – foreign exchange risk
The Group is primarily exposed to foreign exchange risk related to bank deposits, receivables or payables balances and other 
monetary working capital items that are denominated in a currency other than the Company’s functional currency which has been 
determined to be GBP.

The Group does not speculate on foreign exchange and aims to mitigate its overall foreign exchange risk by holding currency in line 
with forecast regional operating expenses, providing an element of natural hedge against adverse foreign exchange movement.

The Group’s exposure to foreign exchange risk at the end of the reporting period, expressed in GBP, was as follows:

Sensitivity – exchange rates
The sensitivity of profit or loss to changes in quoted exchange rates for currencies to which the Group is exposed is as follows, 
based on each relevant exchange rate strengthening (or weakening) by 5%.

There is no impact on other components of equity as the Group is not party to any derivative financial instruments, such as hedging 
instruments, where currency gains and losses would be recognised in other comprehensive loss.

Market risk – commodity price risk
The Group’s batteries use vanadium as the key component of their electrolyte. Vanadium is an elemental metal and is used primarily 
to toughen steel, particularly for the construction industry.

Whilst it is not a mature market traded commodity, such that one can buy forward or derivative contracts, market prices for 
vanadium pentoxide (V2O5) at 98% purity are quoted in US dollars per pound. 

Vanadium forms about two-thirds of the value of the electrolyte, which in turn forms about a quarter of the landed cost of a battery, 
and so a fluctuation in the price of vanadium will impact the profitability of battery sales. An increase or decrease in the market price 
of vanadium of 5% would cause the value of the electrolyte component of a battery to increase or decrease by approximately 3%.

Credit risk – cash held on deposit with banks
Credit risk arises from cash and cash equivalents and deposits with banks and other financial institutions.

Credit risk related to holdings with financial institutions is managed by only maintaining bank accounts with reputable financial 
institutions. The Group aims only to place funds on deposit with institutions with a minimum credit rating of B2 Moody’s.

Credit risk – trade and other receivables
Past due but not impaired
The Group’s credit risk from receivables encompasses the default risk of its customers and other counterparties.

Its exposure to credit risk is influenced mainly by the individual characteristics of each customer or counterparty. The creditworthiness 
of  potential  and  existing  customers  is  assessed  prior  to  entering  each  new  transaction.  A  credit  analysis  is  performed,  and 
appropriate payment terms implemented that may include increased level of upfront deposits for the purchase of battery units. 

Notwithstanding the above, the Group’s standard terms of trade provide that up to 90% of the sales price of a battery unit is paid 
prior to delivery. 

Receivables are considered for impairment on a case-by-case basis when they are past due or where there is objective evidence that the 
customer or counter party may be a default risk. The Group takes into consideration the customer or counter party payment history, its 
credit worthiness together with the prevailing economic environment in which it operates to assess the potential impairment of receivables.

On an ongoing basis, receivable balances attributable to each customer or other counterparty are monitored and appropriate 
action is taken when the relevant balance becomes or is considered likely to become overdue. The maximum exposure to loss 
arising from receivables is equal to invoiced value.

The ageing of trade receivable balances was:

Of the past due amounts at 31 December 2021, £nil was considered to be impaired and related to eight customers (2020: £nil, three 
customers).

Liquidity risk
Liquidity risk relates to the Group’s ability to meet its obligations as they fall due. 

The Group generates cash from its operations that are principally related to the manufacture and installation of vanadium flow 
batteries. The market for reliable and flexible grid-scale storage solutions for energy generated from renewable sources is growing 
and the technology continues to develop.

The development of new and enhanced storage technologies can be capital intensive and the Group has historically funded 
development and early-stage commercial activity primarily from equity investment but also using cash from operations and loan 
funding.

The Group forecasts cash generation using a comprehensive company financial model and monitors the timing and amount of its 
payment obligations.

Capital management
The Group currently has no debt and is funded by proceeds raised through equity placings during 2021 and proceeds from the 
conversion of warrants in 2021.

The board regularly reviews the Group’s cash requirements and future projections to monitor cash usage and assess the need for 
additional funding. At 30 April 2021, the Group had £20.8 million of cash on hand.

29 Related parties
The only related parties of the Company are the key management of the Group. Key management has been determined as the 
CEO and his direct reports.

Invinity Energy Systems plc purchased a total of 24,000 100p shares in the latest fundraising on behalf of two directors. 12,000 
shares were purchased on behalf of Larry Zulch and 12,000 on behalf of Peter Dixon-Clarke. At 31 December 2021 the £12,000 
owed by Peter Dixon-Clarke in respect of the shares had been settled. The £12,000 owed by Larry Zulch has since been settled.

Key management compensation is disclosed in note 8, Staff costs and headcount.
