Metacon adds AEM pathway as EU backs 80% of Greek hydrogen R&D project

Metacon AB (Nasdaq First North Growth Market: META) is widening its hydrogen technology portfolio after wholly owned Greek subsidiary Metacon SA secured €104,326 of public funding for a research programme focused on next-generation anion exchange membrane electrolysis. The funding covers 80% of Metacon’s €130,407 budget in the 24-month AMEL project, leaving the company responsible for approximately €26,081 of its allocated cost while researchers work on catalysts, electrodes, membranes, system components and a 0.5 kW experimental stack. The project targets electrical efficiency above 80% while seeking catalysts that avoid critical raw materials and precious metals including platinum and iridium. Financially, the grant is small compared with Metacon’s commercial projects and recent financing requirements, but strategically it gives the Swedish hydrogen company exposure to a third electrolysis route alongside the pressurised alkaline technology at the centre of its current large-scale business and the PEM systems already offered within its portfolio.

AMEL, short for Green Hydrogen Advancement: Pioneering Anion Exchange Membrane Water Electrolyzer Solutions, is being supported through the Research & Innovation in Western Greece 2024 programme, with public expenditure co-financed by the European Regional Development Fund, Greek national funds and the Western Greece 2021 to 2027 programme. Metacon’s work will be conducted through its Patras-based research operation, which already develops catalysts, reforming systems and other hydrogen technologies. The project is not a commercial electrolyser launch and its planned 0.5 kW stack is several orders of magnitude smaller than the 20 MW alkaline module Metacon introduced in September. Its value lies in testing whether AEM technology can eventually combine some of the dynamic operating advantages associated with membrane electrolysers with lower dependence on expensive or supply-constrained catalyst materials.

Why is Metacon adding AEM research when its commercial strategy is built around alkaline electrolysis?

Metacon’s current large-scale commercial offering is firmly centred on pressurised alkaline electrolysis through its partnership with China-based PERIC Hydrogen Technologies. That relationship already gives Metacon access to industrial-scale stacks, while the company has built its project pipeline around complete European hydrogen plants rather than developing every core electrolyser component internally.

The contrast between that commercial business and AMEL is substantial. Metacon launched a new 20 MW alkaline module in September based on four 5 MW next-generation PERIC stacks, while the AMEL programme will construct only a 0.5 kW AEM stack and test unit. A 20 MW module has 40,000 times the nominal electrical capacity of the planned 0.5 kW research stack, illustrating how early the AEM work remains.

The strategic logic is diversification rather than replacement. Alkaline electrolysis is mature and well suited to large industrial plants, while proton exchange membrane systems offer compact designs and dynamic operation but rely more heavily on expensive platinum-group materials. AEM technology seeks to use a membrane-based architecture while operating in an alkaline environment that can allow less expensive catalyst materials.

If AEM performance, durability and manufacturing economics improve sufficiently, it could eventually create applications that sit between existing alkaline and PEM technologies. Metacon does not need AMEL to displace its current product range for the project to create value; even a future niche technology could broaden the types of hydrogen projects the company can address.

Why does removing platinum and iridium matter for the economics of green hydrogen equipment?

Catalyst materials are one of the constraints facing parts of the electrolyser industry. PEM electrolysers typically use platinum-group metals, including iridium on the oxygen-evolution side, because the acidic environment requires materials capable of combining catalytic activity with corrosion resistance.

Iridium is particularly scarce, creating concerns about whether large increases in PEM manufacturing could eventually encounter supply or cost constraints. European hydrogen research programmes have consequently placed significant emphasis on reducing critical raw material intensity and developing catalyst systems that use more abundant materials.

AEM electrolysis offers a potential route around part of that problem because its alkaline operating environment can support non-precious-metal catalysts. The AMEL programme will specifically investigate catalysts for hydrogen and oxygen evolution that do not depend on critical raw materials or rare and precious metals such as platinum and iridium.

Lower catalyst cost alone does not guarantee cheaper hydrogen. Membrane life, electrode performance, stack efficiency, degradation rates, manufacturing scale and balance-of-plant costs all affect the lifetime cost of an electrolyser. A system that avoids expensive metals but requires frequent membrane replacement could lose much of the apparent economic advantage.

The project’s emphasis on durability is therefore as important as its catalyst work. Metacon will participate in membrane development, electrode optimisation and system-component research while testing operation under both steady-state and repeated start-stop conditions.

Why is the AMEL efficiency target important when AEM electrolysers remain relatively immature?

AMEL is targeting electrical efficiency above 80%, alongside stable operation during constant and cycling conditions. Achieving strong efficiency while maintaining durability is one of the central technical challenges for AEM electrolysis because laboratory performance can deteriorate when membranes and catalysts are exposed to prolonged industrial operation.

The International Energy Agency continues to classify AEM as less mature than conventional alkaline and PEM electrolysis. Commercial AEM products exist, but deployments remain small compared with the multi-megawatt and increasingly gigawatt-scale project pipelines supported by established technologies.

European programmes have been developing AEM systems for several years, with earlier projects validating kilowatt-scale stacks while targeting reduced critical-material consumption, lower capital cost and improved dynamic operation. Newer programmes are increasingly focused on durability, manufacturing automation and larger stack sizes, showing that the industry is moving from basic feasibility toward the harder problem of commercial scale.

Metacon’s 0.5 kW AMEL unit therefore sits firmly within a research environment rather than representing a near-term competitor to industrial electrolysers. The useful outcome would be validated knowledge around materials and system performance that can inform larger prototypes or future commercial partnerships after the 24-month programme.

How does the AEM project fit Metacon’s broader technology development in Patras?

Metacon SA in Greece functions as the group’s primary research centre for catalysis, reaction engineering, process design and reforming technology. The Patras operation developed the company’s proprietary HIWAR catalytic reactor technology and continues to manufacture and develop reforming systems alongside work on externally funded research programmes.

That research base gives the company a different role in AEM than it has within the PERIC alkaline partnership. For large-scale alkaline electrolysers, Metacon combines PERIC’s core stack technology with European engineering, integration, compliance, installation and service capabilities. AMEL allows Metacon’s own scientists to participate directly in fundamental catalyst, membrane and electrode development.

The company has repeatedly used European research funding to broaden that technical base. Metacon SA also participates in projects involving ammonia cracking, carbon dioxide conversion and hydrogen-related process technology, giving it access to research networks without requiring shareholders to finance the entire cost internally.

Public funding does not remove commercialization risk, but it reduces the cost of maintaining technology optionality. With 80% of Metacon’s AMEL budget externally funded, the company can build AEM knowledge for a comparatively limited direct contribution while continuing to direct substantially more resources toward customer projects and commercial alkaline electrolysis.

Why is the timing relevant as the global electrolyser market enters a tougher commercial phase?

The hydrogen equipment market is expanding, but considerably more slowly and unevenly than the project announcements of several years ago suggested. Global installed electrolysis capacity exceeded 4 GW after doubling during 2025, while more than 2.5 GW was under construction for operation during 2026.

At the same time, investment decisions have slowed and numerous announced hydrogen projects have been postponed, resized or cancelled because of weak demand commitments, electricity costs, regulation and financing. More than 100 GW of announced electrolysis capacity could miss a realistic 2030 operating date if developers do not reach investment decisions soon enough.

That slowdown has intensified competition among electrolyser suppliers. Chinese manufacturers benefit from large-scale production and lower equipment costs, while European suppliers face pressure to improve efficiency, reduce capital expenditure and differentiate around compliance, service and technology.

Metacon has responded primarily through its PERIC relationship. The company introduced next-generation alkaline stacks in September with up to 17% higher operating current density and up to 13% lower cell-plate weight than the prior reference design, followed by a compact 20 MW module intended to reduce plant footprint and parts of the installation cost.

AMEL adds a longer-term technology option around the same economic problem. Whether hydrogen is produced using alkaline, PEM or eventually AEM systems, customers ultimately need lower cost per kilogram, dependable output and equipment capable of operating around variable renewable electricity.

How important is a €104,326 grant when Metacon is managing much larger financing needs?

The immediate financial impact is modest. Metacon generated SEK138.5 million of revenue during the first half of 2026, up approximately 30% from SEK106.8 million a year earlier, while the €104,326 AMEL grant represents only a small research contribution beside the company’s commercial operations.

Profitability remains more consequential. First-half EBITDA was negative SEK29.4 million and operating loss was SEK35.4 million, while operating cash flow after working-capital changes was negative SEK57.3 million. The second quarter was particularly difficult because project cost increases pushed gross profit to negative SEK3.2 million and the quarterly gross margin to approximately negative 5%.

Metacon attributed the pressure partly to higher-than-expected assembly costs and late design changes on major electrolysis projects. The experience shows why improving technology is only one part of the investment case. Project execution, procurement, engineering control and working-capital management can have greater near-term impact on earnings than a small R&D grant.

The company completed a rights issue that generated approximately SEK77 million before issue costs and also entered an agreement covering a convertible loan of up to SEK35 million. Current company share information shows approximately 1.75 billion shares outstanding, up materially from the pre-issue share count, making capital efficiency increasingly important as management pursues both commercial growth and technology development.

Against that background, an 80% externally funded R&D programme is financially attractive precisely because Metacon does not need to commit significant internal capital to gain exposure to AEM technology.

Why do Metacon’s Motor Oil and Uppsala projects matter more to near-term valuation than AMEL?

The company’s largest commercial proof point remains its 50 MW electrolysis project for Motor Oil Hellas in Greece. Revenue from that project contributed materially to first-half growth, while Metacon has been manufacturing and integrating components at its Patras facility alongside equipment supplied from China.

Metacon is also working on a 7.5 MW project in Romania and several smaller hydrogen installations in northern Sweden. These projects test the company’s ability to turn technology partnerships into repeatable engineering, delivery and service revenue.

The planned Uppsala reference facility could become another important milestone. Metacon received up to approximately SEK111 million of Swedish Klimatklivet support for a 10 MW hydrogen production plant expected to produce around 1,480 tonnes annually when fully developed. The grant represents 55% of the estimated investment under the company’s disclosed project assumptions.

Compared with those projects, AMEL is unlikely to influence near-term revenue materially. Its relevance lies in strengthening the research pipeline and potentially creating technology options that can matter several years from now.

Metacon’s valuation will therefore continue to depend more heavily on delivering existing customer projects without further margin deterioration, converting its sales pipeline into orders and securing financing for growth. Successful AEM research would add strategic depth, but it does not solve the operational issues already visible in the financial statements.

What does Metacon’s share price say before investors can assess the new AEM programme?

Metacon shares were trading around SEK0.115 immediately before the AMEL announcement on October 7, down roughly 2.6% during the session and about 8% over the preceding five trading days. The shares were also down more than 70% from the beginning of 2026 and were trading close to the bottom of a roughly SEK0.11 to SEK0.72 52-week range.

Using the company’s latest reported share count of approximately 1.75 billion shares, a price around SEK0.115 implies an equity value of roughly SEK200 million. That calculation is more representative of the current capital structure than market-capitalisation figures based on the lower share count that existed before the 2026 rights issue.

Because the funding announcement was released at approximately 14:59 Central European time and the available market quotation immediately preceding it was recorded only minutes earlier, there was no meaningful post-announcement reaction available at that point. Any movement earlier in the session should not be attributed to the AEM announcement.

The depressed longer-term share performance indicates that investors are assigning considerable weight to financing, execution and profitability risks despite Metacon’s growing project portfolio. A €104,326 grant is too small to change that picture on its own.

What would turn Metacon’s AEM research from technical optionality into commercial value?

The first test is whether AMEL reaches its stated technical targets. An electrical efficiency above 80%, stable cycling behaviour and credible catalyst performance without reliance on platinum or iridium would provide a foundation for larger prototype work.

Durability will be particularly important because AEM technology has historically faced challenges around membrane and component lifetime. A high-efficiency stack that degrades rapidly would struggle to compete with mature alkaline systems whose long operating histories are already understood by industrial customers.

Scale comes next. Moving from a 0.5 kW research unit into tens or hundreds of kilowatts and eventually megawatts requires changes in manufacturing, thermal management, gas handling, controls and system integration. Metacon has not announced a commercial AEM product roadmap or indicated that AMEL will automatically lead to one.

The company therefore gains inexpensive strategic optionality rather than a new revenue line. Its existing alkaline projects remain responsible for proving that Metacon can grow sales while improving project margins, while AMEL gives the Patras research team two years to test whether AEM technology deserves a larger place in the portfolio.

That balance is commercially sensible in a hydrogen market where technology costs are falling and supplier competition is intensifying. Metacon does not need to choose between alkaline, PEM and AEM today, but maintaining knowledge across the technologies could become valuable if future hydrogen projects demand different combinations of scale, dynamic operation, capital cost and raw-material intensity.
