Stargate Hydrogen has received a strategic investment from Repsol’s Corporate Venture arm, which acquired a minority stake in the Tallinn-based company. The funding will support the scale-up of Stargate’s production capabilities—currently at 140 MW per year—and accelerate its R&D activities. The alliance also aligns with the company’s international expansion plans across key regions including Europe, the Middle East, and Asia. For Repsol, one of Spain’s largest hydrogen producers, the partnership contributes to its goal of reaching 600–700 MW of installed hydrogen capacity by 2030 and integrating emerging technologies into its decarbonization roadmap.
Stargate Hydrogen develops next-generation alkaline electrolysers for green hydrogen production, using a proprietary stack architecture and advanced ceramic catalysts to improve system efficiency and lower costs. Headquartered in Tallinn, the company works with energy utilities and industrial customers across multiple regions and is recognized under the EU’s Important Projects of Common European Interest (IPCEI) for hydrogen.
“Repsol is the largest producer and consumer of hydrogen in Spain; therefore, it has extensive first-hand experience of the complexities of hydrogen projects. We are delighted that this partnership will allow us to work together on multiple fronts, from R&D and product development to commercial deployment of Stargate’s innovative electrolyser technology,” said Marko Virkebau, CEO of Stargate Hydrogen.
Earlier in 2025, Stargate secured an 11 million EUR A-round and inaugurated its new factory. The incorporation of Repsol as an industry partner reinforces this momentum and will enable the expansion of its manufacturing capacity, accelerate research and development initiatives, and strengthen its commercial operations across Europe, the Middle East and Asia.
“Renewable hydrogen is essential to our decarbonisation roadmap. What we are looking for are innovative approaches to its production, enabling more efficient production. We have closely followed Stargate Hydrogen’s work in recent years and are confident that it can be a great ally for us to accelerate our renewable hydrogen developments,” said Gema García, Director of Open Innovation and Corporate Venturing at Repsol.
By 2030, the group plans to reach between 600 MW and 700 MW of installed hydrogen capacity.
This industry alliance is built on a shared goal: significantly reducing the cost of renewable hydrogen production to accelerate the decarbonisation of heavy industries and enhance Europe’s energy independence in critical energy production technologies. Stargate Hydrogen’s patented technology, featuring advanced ceramic catalyst materials and novel stack design, offers significant economic advantages over competing solutions, enabling affordable renewable hydrogen production on a large scale. The company´s current manufacturing capacity is 140 MW per year, which can be scaled up to 1GW+ with modest additional investments.
