Stargate Hydrogen's EUR 20.6 million EU Innovation Fund grant makes the Baltics an electrolyser manufacturing region
Stargate Hydrogen has signed a EUR 20.6 million EU Innovation Fund grant agreement to expand its Tallinn electrolyser plant into one of Europe's largest. We look at what the money buys, why a precious-metal-free catalyst matters for PtX project economics, and what a Baltic manufacturer at industrial scale changes for the region's hydrogen ambitions.

Green hydrogen is still expensive and the equipment is still scarce. But the machines that make it are increasingly being built in our part of Europe. On 15 September 2026, Stargate Hydrogen signed a EUR 20.6 million grant agreement with CINEA under the EU Innovation Fund to expand its Tallinn manufacturing plant. A Baltic deeptech company is moving from a first factory to industrial scale on European public money.
From a first factory to European scale
Stargate opened its Tallinn electrolyser factory in 2025, at a moment the company itself called one of industry hesitation. A year later it is signing a grant to expand it in phases — 250 MW a year of alkaline electrodes, 150 MW of pressurised stacks, 66 MW of complete systems. Capacity at every step of the chain, so it can sell into other manufacturers’ supply chains as well as directly to developers.
CEO Marko Virkebau expects Stargate to become one of Europe’s largest electrolyser manufacturers once the expansion lands. That is his claim rather than an audited ranking, and it depends on how much announced European capacity actually gets built. The direction, though, is not in dispute.
A ceramic catalyst instead of precious metals
The technical core is what makes the economics work. Stargate’s electrodes use a patented ceramic-based catalyst that replaces precious metals, built around its own stack design. That strips iridium and platinum group exposure out of the cost stack — volatile prices, concentrated supply, and one of the quieter constraints on scaling electrolysis worldwide. For a Power-to-X business case, electrolyser CAPEX is the line a developer can actually influence through procurement. The European Commission has recognised the underlying technology as an Important Project of Common European Interest.
This is deeptech, and it is happening in the Baltics
The regional assumption has been that the Baltics deploy hydrogen technology rather than develop it — we host the projects, the engineering value sits further west. Stargate is a fairly direct rebuttal. An EUR 11 million Series A brought in Repsol and Estonian state VC SmartCap. A turnkey system has been delivered to Fortum in Finland, stacks supplied across Europe, Turkey and India, with Utilitas, ABB and Rockfin among the clients. Research, first factory, strategic co-investment, delivery references, EU-funded expansion. Each step de-risked the next, and Baltic hydrogen ecosystem stakeholders should read that sequence as a template.
The resilience question Europe is finally pricing in
This grant sits inside a policy shift. The Net-Zero Industry Act sets a benchmark that around 40 percent of EU electrolyser deployment should be manufactured in Europe, with resilience criteria obliging public authorities to weigh third-country dependence rather than award on headline price alone. REPowerEU and the Clean Industrial Deal point the same way. Europe’s problem was never announced capacity — it is that much of it runs below nameplate. Expanding a manufacturer with real delivery references and a differentiated materials position is a more useful use of ETS revenue than another capacity announcement.
What a factory few hundred kilometres from Riga / Vilnius changes
Virkebau named the target markets: green ammonia, synthetic natural gas, sustainable aviation fuel. That is almost exactly the Baltic PtX pipeline. Proximity is not sentiment — it is lead times, freight, commissioning support and engineers on site within a day rather than a week. On a first-of-a-kind project in Latvia or Lithuania, schedule risk during commissioning usually outweighs a modest equipment price difference. It also simplifies the EU-content story when a project goes looking for public co-financing.
What to take from it
Hydrogen deeptech can be built here and financed at European scale — the ceiling is higher than the region has assumed. The Innovation Fund is a live route for Baltic industrial projects, and its ETS-funded logic rewards demonstrable emissions reduction at scale. And the EU-made equipment agenda is moving from rhetoric into procurement rules, so European content is becoming a financing advantage rather than a constraint.
The caveat is honest enough: a grant agreement is not a commissioned factory, and phased expansion means the capacity arrives over years. The 150 jobs and roughly 3 million tonnes of CO2 equivalent avoided over ten years are the applicant’s own projections. We will be watching how the phases land.
