  Content	# Part 3: Global Expansion, Partnerships, and Developments. # The UK **Cap and Floor** This is without question the biggest potential catalyst in the company's history so listen sharp. In October 2024, the UK government announced the implementation of the LDES Cap and Floor Scheme, to be delivered by the Office of Gas and Electricity Markets (Ofgem).^(58) The program, born out of the curtailment crisis in the country, will reward selected projects with revenue floors and ceilings (caps): If the project's revenue falls below the floor, it will be topped-up by the consumers, and if it rises above the cap, the difference will be returned to the consumers. The scheme thus offers incredibly lucrative, guaranteed revenue stability to developers. Ofgem disclosed it intends to reward up to 7.7 GW of projects through to 2035,^(59) which is about 22% of the current total power demand of the UK grid.^(60) The application process officialy opened on 8 April 2025 and has two steps: Eligibility Assessment and Project Assessment. The Eligibility Assessment meant to confirm that applicants met the minimal conditions: Projects had be capable of at least 8h discharge duration at full power, and had to have either TRL 9 with a minimum of 100 MW power capacity (so called stream 1) or TRL 8 with a minimum 50 MW power capacity (stream 2).^(61) Projects were further devided into tracks, with track 1 projects deliverable by 2030 and track 2 projects by 2033. They were also asked to show basic deliverability evidence as pertains to stuff like grid connection, planning consent, etc. The Eligibility Assessment outcome was published on September 23.^(62) Out of 171 projects that applied, 77 passed this stage, 21 of whom utilize VRFBs. Of those 21, 5 are entirely VRFBs, while 16 are hybrid projects of VRFBs and ZBBs. *All* 21 projects named Invinity as their VRFB supplier. The 16 hybrid projects all belong to Frontier Power Limited and name Eos as their ZBB supplier. Only 1 project of the 21 belongs in Track 2. The total VRFB energy capacity of the 21 projects is 16.7 GWh. The largest of them is Hagshaw LDES, a pure VRFB project with 500 GW power output and 6 GWh energy capacity. Of the remaining 56 projects, 48 use LIBs. Needless to say, this is massive. The smallest of these projects has a larger VRFB energy capacity (\~>=260 MWh) than all of Invinity's currently deployed fleet *combined,* and the largest (Hagshaw) would likely mean over a billion dollars in revenue on its own. We are now in the middle of the project assessment window, with an initial decision list to be published this spring, and the final list in the summer. The full assessment criteria are too involved to be discussed here in detail (you can read about them in references 63-66), but we can examine the parts that are more technology/supplier-specific in nature to get an idea of Invinity's prospects, particularly compared to the LIB projects. Ofgem asesses the projects across three pillars: Financial Assessment, Ecnonomic Assessment, and Strategic Assessment. Financial Assessment broadly measures the direct bankability of the project. Its key metric is **R=Project revenue as a % of the project floor level**, meant to gauge whether a project will be a burden on consumers by spending too often below the floor. The floor level is determined by Ofgem's assessment of the project's total costs over a default 25 years regime, where a project with higher costs requires a higher floor to cover them and is henced punished with a lower **R** value. The key point is that, unlike commercial LCOS estimates with their 8-12% discount rates, Ofgem determines the floor so as to have a rate of return of **only 4.47% CPIH-real** (it's common for government schemes to use lower discount rates than commercial initiatives). This *enormously* rewards longer lived assets. An LFP battery that reaches EOL after 6,000 deep cycles and needs to be replaced after only 15 years will be hit with a 50% present replacement cost. Moreover, projects are granted the ability to increase their regime length beyond 25 years, which will reduce the floor level by spreading it over a longer time, as well as include EOL value in the assessment, which Ofgem assumes to be 0 by default. Both of these further buff VRFBs with their 30+ year ratings and high EOL value. The Economic Assessment measures the project's broader impact on the UK grid and socio-economic consumer welfare, and is a mixture of quantitative and qualitative scoring. Most of it is project-specific metrics like effect on wholesale market costs, supply security, avoided curtailment, local community impact, etc. But one metric to take note of is "skills and supply chain – qualitative impact". Ofgem doesn't use a mechanistic "number of jobs created/supported" metric since they aknowledge the possiblity that, for example, a project will create some jobs by displacing others. However, in their own words: >"We recognise that some Projects may have a positive impact on local labour markets and supply chains, through investment in specialised skills, or their commitment to source workers and materials from local markets and domestic supply chains, or by supporting the stimulation and export potential of UK-developed technology. Where this is the case, we will consider any evidence put forward by Projects and consider it as part of the qualitative assessment of wider economic and social benefits." This is relevant to us because Invinity is the *only* stationary battery manufacturer in the UK. The acceptance of VRFB projects and the resulting ramp-ups of Bathgate and Motherwell will directly create dozens of skilled jobs, at no expense to others.^(67) Moreover, Invinity's unique status places pressure on the UK government to signal that they encourage and reward domestic production, which is clearly an image they want to broadcast.^(68-70) Ofgem even directly refers to references 68,69 in their assessment documentation. Lastly, the strategic assessment is a smorgasbord of everything that doesn't fit in the other two. It includes deliverability, risk of cost overruns, project interdependency, etc. The metric of most interest to us is the first one they list: technology diversity. Quoting them again: >"We expect it could be in the long-term interest of consumers that we limit overreliance on a narrow set of LDES technologies. There may also be societal benefit from insight derived from the relative performance of different LDES technologies. As part of the Strategic Assessment, we will consider the overall portfolio of assets that perform strongly within the Economic and Financial Assessments and its measure its technological diversity." They do add a caviat that they will not uphold technology diversity at all costs, and that the economic and financial factors are still the higher priority, but this is still encouraging. All of these taken together, along with the fact that the government awarding these schemes literally has a 19% stake in Invinity (I know, the agencies are supposed to be independent, but behind closed doors...) lead me to believe that the scenario where VRFBs will be left in the lurch is highly unlikely. While not all 21 projects will be accepted, all it would take is a fraction to launch Invinity into the stratosphere, and for at least that much I am very optimistic. **Killellan** Another development to keep an eye on is the **Killellan AI Growth Zone**, a proposed hyperscale hub in Argyll, Scotland combining data center capacity with on-site renewables.^(71) The project is led by Argyll Infrastructure Holdings Limited, with partners listed in its application including Schneider Electric, Lenovo, CorPower Ocean, Invinity Energy Systems, and Suir Engineering. Of relevance to us is the renewable aspect. The project's planned power capacity is 500 MW by 2030, and 2 GW by 2035. Earlier stages describe a micro-grid configuration, with grid integration planned at the advanced stages. If we assume a resonable minimum duration of 8h, that's at least 16 GWh of storage capacity, comparable to the entire Cap and Floor lineup. Invinity has been named as the supplier of this capacity.^(72) The project is proposed as a bid for the UK Department for Science, Innovation, and Technology (DSIT)'s AI Growth Zone programme.^(73) Launched in early 2025, this is the UK's main initiative to encourage a domestic AI industry. It rewards selected projects with priority access to grid power, lower operating electricity costs, streamlined planning and permitting, and possible financing support. Applications are made on a rolling basis, with no time limit. Unlike Cap and Floor, DSIT don't list a detailed assessment criteria for projects, only the minimum criteria: projects are required to demonstrate access to >=500 MW by 2030, water and land availability, suitable planning and delivery feasibility, assessments of local impact, and disclose the requested level of government support.^(74) Considering that Killellan will live or die based on its acceptance into the programme, it's harder to get an estimate on its prospects compared to Cap and Floor. But there were some encouraging developments recently. On 10 Jan 2026, the Swiss firm D M Investments AG has taken control of Argyll Infrastructure Holdings Limited with >75% ownership of shares and voting rights.^(75) Before this, the funding efforts have so far raised only an initial £15m and unlocked negotiations for another £100m out of the total £15bn required for the project.^(76) The new institutional management materially improves their chances to raise the required capital. That being said, even within arguably the biggest infrastructure investment frenzy since the Railway Mania, £15bn is a lot of money. It's therefore best to regard Killellan more as a (very large) possible bonus, rather than a major part of the thesis. # China Unsurprisingly, China currently leads the global charge when it comes to energy storage in general and VRFBs in particular. With their penchant for mega-projects, their energy storage focus has historically been on pumped hydro, but is increasingly broadening to other technologies with goals to achieve more than 180 GW of installed new-type battery storage by 2027 (new-type meaning other than hydro)^(77). Their 15th five-year plan will be released this month and is expected to detail their storage plans up to 2030. In January 2026, the world's first 1GWh VRFB project was completed in Xinjiang, developed by state-owned China Huaneng Group, with Rongke Power supplying the batteries.^(78) I hinted at Invinity's Chinese connection in the history section but it goes much deeper than that. First, the Baojia partnership is still going strong. In their recent end of year update they announced that they completed the transfer of Endurium's initial balance of system manufacturing to Baojia, which can be expected to further reduce its costs. More exciting is the UESNT partnership. The vanadium supply deal already mentioned is fantastic, but it's not even the headline of the agreement. Quoting Invinity directly:^(79) >"Under the Agreement, which runs to 2030, UESNT will gain the right to market, sell and manufacture ENDURIUM VFBs for the Chinese market. UESNT will pay Invinity a royalty fee based on the volume of ENDURIUM VFBs delivered each year as well as two one-off royalties, on satisfaction of certain conditions. >Under the Agreement, Invinity is able to source sub-components and completed ENDURIUM systems manufactured by UESNT for delivery outside of China, which the partners expect will significantly reduce the manufactured cost of ENDURIUM projects delivered worldwide and further enhance Invinity’s global competitive position." So on one hand, Invinity gets additional cost reduction by sourcing manufacturing to another Chinese firm (in addition to the vanadium agreement). On the other hand, they get a high-margin stream of cash from UESNT's own sale royalties. But that was just the appetizer. Last September, Invinity, representing a consortium of companies including Baojia, UESNT, and International Resources Limited (IRL, a Hong Kong-based company with a vanadium mine in South-Africa), signed an MoU with state-owned Chinese juggernaut Xiamen C&D, a Fortune Global 500 company (ranked #98). Again quoting Invinity:^(80) >"The MoU envisages that C&D, with the assistance of the Xiamen Municipal Government, will support the proposed Consortium in scaling up Chinese manufacturing capabilities for Invinity batteries in the region. Furthermore, C&D have indicated willingness to offer the proposed Consortium working capital support and also provide it with access to C&D’s global supply chain platform, which is intended to accelerate the proposed Consortium’s plans to optimise procurement, logistics, and distribution for large-scale production." So now Invinity has established a firm foothold in China, with multiple signed partnerships and backing by one of the largest companies in the world. It will be noted that this is still just an MoU, not a binding agreement, and negotiations about the details are ongoing. But considering Invinity's track record in China and the high profile of the signing—attended by senior British and Chinese government officials including the British Ambassador to China— there is reason to be very optimistic about their future in the country. # The US You would not be blamed for thinking that a battery manufacturer could face headwinds in the US nowadays, but it turns out the opposite is true. The Trump administration famously (or infamously) crippled the Biden administration's tax credits for solar and wind projects through the One Big Beautiful Bill Act (OBBBA), which changed the eligibility deadline from a gradual phaseout starting late 2032 to a hard cutoff in 31 Dec 2027. But the new act explicitly excludes energy storage technologies from this change,^(79) and the qualification timeline actually improved under it, with a gradual phaseout starting only in 2034. The credits can be categorized by those given to manufacturers, and those given to developers. For domestic manufacturers, IRS §45X gives a transferable tax credit of $45 for every kWh of produced capacity. Moreover, domestic producers of electrode active materials and critical minerals (including vanadium) get a 10% tax credit. For developers, IRS §48E starts with a base transferable tax credit of 6% of the energy storage CapEx. This turns to 30% if the project meets PWA requirements, gets another 10% if it satisfies domestic content conditions, another 10% if its in an energy community, and another 10-20% for <5MW projects in low-income areas, for a total of up to **70%** credit. And here's the kicker. The OBBBA did introduce one significant change: a Foreign Entity of Concern (FEOC) restriction. Both §45X and §48E credits will not apply if more than 45% of the energy storage cost is derived from components that "recieve material assistance from a prohibited foreign entity", with the threshold decreasing by 5% every year starting 2026 down to 25% in 2030. This includes any components sourced from North Korea, Russia, Iran, or—you guessed it—China. This immediately includes all LFP BESS with Chinese cells. A domestic VRFB manufacturer will therefore not only be able to compete with Chinese LFP—it will wipe the floor with it. It compounds a 10% raw material discount, a 45$/kWh production discount, and up to 70% developer CapEx discount, while the LFP gets nothing while getting hit with tariffs. The only possible competition will be domestic LFP cell producers. There are only a few of them currently in the US, all early stage (LG Energy Solution is probably the most advanced), and none capable of matching Chinese costs. Invinity did not sleep on this opportunity. Last month, they announced a new MoU with a (yet undisclosed) US partner to open a fourth production site in California with a capacity of up to 1 GWh per year. They explicitly state that the facility will meet the domestic content and sourcing requirements of the OBBBA. This will necessarily require domestic vanadium sourcing, and there is reason for confidence here as well. In 2022, Invinity signed an MoU with U.S. Vanadium to create a joint venture combining vanadium electrolyte supply with battery manufacturing. The original terms of the MoU are probably no longer applicable, but this shows Invinity already has the connections to allow for rapid deployment, and they have already disclosed that they're lining up a North American supplier. In the same announcement, they revealed the "Vice President, Business Development" appointment of Shane Mcbee, who transferred over from the position of "Vice President, Strategic Corporate Accounts" at Eos (take from that what you will). Both domestic electrolyte sourcing and battery manufacturing are scheduled to start later this year. Aside from the federal boons, there are also many state-level initiatives to enjoy from with this new US presence. Here's a brief rundown of the big ones: **California**: Has a dedicated LDES program specifically for non-lithium technologies that already funded the Viejas project.^(54) Will solicit up to 1 GW of 12h+ LDES to be comissioned between 2031-2037 (separate from an additional 1 GW of multi-day storage).^(81) Many cities and towns in the CA are imposing bans and moratoriums on LIB BESS, most recently Vacaville.^(7) Last month the state signed an MoU with the UK, expressing intent to stengthen cooporation, particularly in advancing renewable energy and "energy storage, including long duration technologies."^(82) **New York**: Targets 6 GW of energy storage by 2030, including 3 GW of bulk storage and 1.5 GW of retail storage.^(83) Explicitly carves out 20% of bulk solicitations to 8h+ LDES.^(84) Allows contract terms of up to 15 years for lithium-ion batteries but up to 25 years for non-lithium technologies. Is experiencing a similar and perhaps even stronger trend of LIB BESS bans, most recently Troy.^(85) **Massachusetts**: Plans to solicit 5 GW of energy storage by 2030, with at least 750 MW earmarked for 10-24h LDES.^(86) # India India has ambitious goals to achieve 50% installed non-fossil fuel energy capacity and reduce emission intensity of its GDP by 45%, all by 2030. The Indian government aknowledges the importance of energy storage in this effort, and predicts that the country will require 411 GWh of storage by 2031-32, 236 GWh of which from BESS.^(87) By the nature of renewables, there's no doubt that a large portion of this new capacity will be LDES. Marking Invinity's entry into the Indian market is their strategic partnership with Atri Energy Transition, signed with the explicit intent of establishing production capacity within the country. The reasoning is that India is placing increasing emphasis on domestic production through both its tenders and incentive programs. One noteworthy program is the Advanced Chemistry Cell Production Linked Incentive (ACC PLI), where firms bid for cash subsidies for manufactured production, for a maximum of ₹2000/kWh (\~21.8$/kWh).^(88) To qualify, manufacturers must commit to ensuring at least 25% of cell value is produced domestically within 2 years of the appointed date, with the number going up to 60% after 5 years. I won't go over the details since this post is long enough, but the program is devised as such that manufacturers who commit to a higher domestic production fraction and larger production capacity can get higher subsidies. Note that although the program uses the word "cell", it's technologically agnostic. Moreover, Indian government tenders often classify bidders as Class-I local suppliers (>50% domestic production), Class-II (>20%), or non-local (<20%), with preference given to the higher classes (classic India).^(89-90) In-country manufacturing will therefore give Invinity a significant competitive advantage. Note that the blazing hot summers in many parts of India give VRFBs an additional boost compared to LIBs, due to their ease of cooling. # Canada The Canadian federal government offers a 30% refundable investment tax credit on clean technology, including BESS. Excitingly, just last month it began consultations on potential domestic content requirements,^(91) which would be fantastic news for Invinity with their operational Vancouver factory. On the provincial level, Ontario leads the charge with its IESO Requests for Proposals (RFP), particularly the Long-Term 2 (LT2) and Long Lead-Time (LLT) RFPs. LT2 is divided into a capacity services track, LT2(c), and energy supply track, LT2(e)^(92). LT2(c) is of most relevance to us: it aims to procure up to 1.6 GW of energy storage capable of at least 8h discharge duration, and has a built-in incentive for 12h+ projects. The procurement will be done in 4 annual windows, from 2026 to 2029. The first window aims to procure up to 600 MW of storage. It's framed as a reverse-auction, where projects bid their desired fixed capacity payments in $/(MW-business day) and get possible bonuses from incentives like the 12h+ one. The lowest bidders then get chosen and awarded 20-year contracts. The submission deadline for the first window was on 18 Dec 2025, and results are expected to be announced on 16 Jun 2026. LLT is a variation of LT2 designed for projects that require longer lead times but offer longer lifetimes.^(93) Like LT2, it's divided into LLT(c) and LLT(e), and uses essentially the same selection scheme. LLT(c) aims to procure up to 800 MW of storage. The main difference is that LLT projects are awarded 40 year contracts, but eligible projects must reach commercial operation within at least 5 years of the award. The details are still being drafted, but right now final proposals are due 1 Oct 2026 with selection notice on 30 Mar 2027. Invinity explicitly mentioned both LT2 and LLT in their H1 2025 investor presentation, and has undoubtably contracted bidding projects. The cold winters in Canada can also be expected to give VRFBs a relative performance boost (the VS3 Alberta project was installed inside a simple shed with no additional HVAC). # Taiwan A few months after Everbright's investment in Invinity, the companies signed an MoU to establish a manufacturing partnership. This transformed into a binding agreement in February 2024. The agreement stipulates that Everdura will manufacture Endurium batteries locally, with cell stacks bought directly from Invinity's UK/Canada factories, targeting the sale of over 255 MWh of capacity over a three-year period. It will also pay Invinity a royalty fee for a precentage of product sold. In December 2024, Everdura announced it was building a manufacturing base for Endurium with an initial capacity of over 1 GWh per year.^(94) In March 2025, the Invest Taiwan Office announced that Everdura would invest nearly NT400 (\~$12.6m) in Sanyi, Miaoli to build production lines for vanadium flow battery energy storage.^(95) Invinity therefore gains revenue from selling the cell stacks as well as yet another source of high-margin royalties from a manufacturer abroad. # Summary So, what we have here is the leading manufacturer of a specialized product in rapidly increasing demand within one of the fastest growing markets today. They're enjoying explicit government support and penetrating nearly every t op economy on the planet with a piling collection of strategic partnerships, no debt, and a large reserve of cash providing it a clear runway. All this while global policy continuously produces new programs and initiatives with each promising to increase their revenue by orders of magnitude. And no one is talking about it. There are almost no news articles, no online discussions, and all of three analyst coverings. The market cap remains around a comical \~$150m, and the trading volume is miniscule. It's a rare enough thing to find a hidden gem in this day and age, but I cannot interpret this in any other way. If I had to guess, its a result of LIBs and SIBs pulling in all the attention, the company being based in the UK and primarily traded on the LSE, and the last earning's top line completely misrepresenting the their current status. Whatever the reason may be, I'm not complaining, since it allowed me to enter early and enjoy the ride.
