IN Brief:
- Stargate Hydrogen has signed its first UK partnership, teaming with Seacht Group to pursue green hydrogen projects in the British market.
- The move brings Stargate’s ceramic-based alkaline electrolysis platform into a market where industrial decarbonisation and electrolytic hydrogen capacity are both being actively developed.
- The UK pipeline remains policy-backed, with 11 HAR1 projects supported, 27 HAR2 electrolytic projects shortlisted, and a national ambition of up to 10 GW of low-carbon hydrogen capacity by 2030.
Stargate Hydrogen has made its first move into the UK market through an agreement with Seacht Group, a step that shifts the Estonian electrolyser developer from continental growth plans into one of Europe’s more active hydrogen project markets.
The partnership is aimed at securing green hydrogen opportunities across the UK and brings together Stargate’s electrolysis technology with Seacht’s local engineering and energy-sector presence. The companies are using the agreement as the start of a broader business-development push, and Stargate has signalled that it wants to build further relationships with engineering companies and EPC contractors as it expands its UK footprint.
The technology angle is what makes the move worth watching. Stargate is focused on ceramic-based alkaline electrolysis and has been working on improving the efficiency and cost profile of alkaline systems for industrial-scale deployment. On its own technical materials, the company points to high-current-density, high-efficiency, platinum-group-metal-free development work, as well as validation and research links with organisations including Fraunhofer, ZSW, TalTech, and the University of Tartu. That gives the UK entry a more defined shape than a simple market-access announcement: this is an attempt to place a specific electrolyser architecture into live project pipelines.
The timing is logical. The UK hydrogen market is still heavily shaped by policy support, but it is no longer just strategy language and conference panels. Government support for 11 green hydrogen projects under Hydrogen Allocation Round 1 was confirmed in the Autumn Budget 2024, with those projects expected to become operational between 2025 and the end of 2026. A further 27 electrolytic hydrogen projects were shortlisted under HAR2 in April 2025, while the UK’s stated ambition remains up to 10 GW of low-carbon hydrogen production capacity by 2030, with at least half intended to come from electrolytic hydrogen.
That does not guarantee a smooth route to market. UK hydrogen projects still need workable economics, offtake certainty, and execution discipline, and developers are competing in a market that is trying to scale supply chains at the same time as it defines demand. Even so, the Seacht agreement gives Stargate a local route into a project environment that is materially more developed than it was a few years ago.
The next question is straightforward enough. A first partnership gets a technology provider into the room. Converting that position into equipment selection, project awards, and operating capacity is harder. With more UK hydrogen schemes moving through allocation, due diligence, and delivery, that test is now much closer than it used to be.
