How Estonia won EUR 20.6 million for hydrogen
Stargate Hydrogen's EUR 20.6 million EU Innovation Fund grant is the last step in a decade-long sequence, not a lucky break. We trace how state venture capital, a first factory and real delivery references made the application credible, and what a Latvian project would need to assemble before writing its own.

There is a version of this story that reads as just another grant announcement. We would rather read it as a decade of patient work finally getting the backing it earned. On 15 September 2026, Stargate Hydrogen signed a EUR 20.6 million grant agreement with CINEA under the EU Innovation Fund to expand its electrolyser plant in Tallinn. Ten years ago the technology behind it was laboratory work. Today it is a factory that Europe has decided to help make bigger.
A decade of steps, each one earning the next
What makes the Estonian story instructive is not the size of the cheque. It is the sequence. Nobody handed Stargate EUR 20.6 million on the strength of a good idea; they arrived at this grant having already proved, step by step, that they could build and deliver.
Laboratory development of a ceramic-based catalyst that replaces precious metals in alkaline electrodes, and a proprietary stack design built around it.
An EUR 11 million Series A bringing in Repsol, one of Europe’s major hydrogen producers, alongside SmartCap, the Estonian state-owned venture capital firm.
A first electrolyser factory opened in Tallinn in 2025, at a moment the company itself described as one of industry hesitation.
Recognition by the European Commission of the underlying technology as an Important Project of Common European Interest.
Real delivery references — a turnkey system to Fortum in Finland, stacks supplied across Europe, Turkey and India, with Utilitas, ABB and Rockfin among the clients.
And now an EU Innovation Fund grant to expand the plant in phases.
Read down that list and the grant stops looking like luck. Each step made the next one financeable. That is the part worth carrying home.
Public money arriving at the right moments
Two public interventions shaped this trajectory, and they arrived at different stages for different reasons. SmartCap came in at the venture stage, when the technology still carried real risk and private capital alone would have priced that risk harshly. The Innovation Fund came in at the industrial stage, when the question had shifted from whether the technology works to whether it can be built at volume.
Neither replaced private capital. Both made private capital comfortable. Repsol did not invest because the Estonian state was in the round, but a state co-investor does change how a strategic partner reads the risk. This is what a functioning public support architecture looks like in practice, and it is a fair question for Latvian hydrogen ecosystem stakeholders to ask of our own instruments: do we have something that plays the SmartCap role, at the stage where it matters?
The Innovation Fund is competitive, not closed
The Innovation Fund has a reputation in this region for being something other people win. The numbers do not entirely support that reputation, but they do explain it. In the 2024 call, CINEA received 359 applications against a budget that was oversubscribed more than ninefold, and the 54 projects that eventually signed grant agreements drew on EUR 2.7 billion and spanned 17 countries. Competitive, clearly. Also open to seventeen different national contexts, several of them small.
The instrument is financed by Emissions Trading System revenues, which shapes what it rewards: demonstrable greenhouse gas avoidance at scale, genuine innovation, and a project mature enough to actually get built. Stargate’s file could answer all three. The expansion will produce 250 MW a year of electrodes, 150 MW of pressurised alkaline stacks and 66 MW of complete systems, create around 150 direct high-value jobs, and — on the company’s own projection — avoid roughly 3 million tonnes of CO2 equivalent over its first ten years. Those last two are applicant figures rather than independently audited outcomes, but they are the kind of figures the instrument asks for, backed by a factory that already exists.
What a Latvian application needs before it is written
The honest lesson is that the application is the last step, not the first. What carried Stargate through was everything accumulated beforehand: a technology with a defensible differentiator, a state co-investor willing to take early risk, an operating facility, paying customers in several countries, and an EU-level technical endorsement. A Latvian applicant assembling that track record now is doing the work that makes a future application credible.
It also helps that the differentiator here is a materials story. Removing iridium and platinum group metals from the electrode cuts exposure to volatile prices and concentrated supply — a problem the EU is actively trying to solve, which means the project answered a policy question as well as a technical one. Aligning a Latvian project with a live European problem is not cynicism. It is how funding instruments are designed to work.
Why a neighbour’s success is not a competitor’s
There is a reflex in small markets to read a neighbour’s win as a loss of position. We would resist it here. A large electrolyser manufacturer roughly "next door" to Riga means shorter lead times, easier commissioning support, engineers who can be on site in a day, and a straightforward European-content story when a Latvian project goes looking for public co-financing.
Chief Executive Marko Virkebau named the target markets as green ammonia, synthetic natural gas and sustainable aviation fuel. That is close to a description of the Baltic Power-to-X pipeline. A regional supplier serving regional projects is how a value chain becomes real rather than notional.
What to take from it
That hydrogen deeptech can be developed, financed and manufactured in this region — not only deployed here. That public capital works best when it shows up early enough to change the risk picture, then again at the point of industrialisation. And that the Innovation Fund rewards a body of work rather than an ambition, which means the preparation starts years before the call opens.
A grant agreement is not a finished factory, and phased expansion means the capacity arrives over years rather than quarters. We will be following how it lands. But Estonia has just demonstrated something the whole region benefits from seeing proved.
