Tallinn-based CleanTech company Stargate Hydrogen has successfully raised €11M in Series A funding to scale up production of their innovative precious metal-free electrolysers. The investment came from strategic customers and financial investors, including Giga, UG Investments, and SmartCap Green Fund.
Stargate Hydrogen’s breakthrough lies in their unique approach to electrolysers, which produce green hydrogen without using precious metals. Instead, the company utilises ceramic-based catalyst materials that operate at higher efficiency than existing solutions, significantly reduce energy consumption, and keep investment costs low.
Their proprietary stack technology improves reliability throughout the project lifecycle while minimising equipment degradation. This approach enhances the economics of green hydrogen production and increases the return on investment for project developers.
The company’s technology has received notable recognition, complementing the unique Estonian hydrogen ecosystem. The country aims to develop the world’s first nationwide Hydrogen Valley, integrating hydrogen production, distribution, and utilisation across industries, transport, and energy systems. According to the official Estonian Hydrogen Roadmap, it could produce between 2,000 and 40,000 tonnes of green hydrogen per year by 2030, depending on renewable energy availability and market conditions.
Stargate Hydrogen’s performance was validated by ZSW in Stuttgart, a leading European test centre. The European Commission designated it an “Important Project of Common European Interest.” Fortum, a major Nordic utility company, recently selected Stargate as the supplier for its alkaline electrolysis plant in Finland.
“To have strategic customers investing into the company is the strongest testament to the progress we made,” said Marko Virkebau, CEO of Stargate Hydrogen. “This funding gives us firepower to execute our roadmap, enhance our production capabilities, and provide our customers with electrolysis technology that allows significant cost-down on the price of green hydrogen.”
With this funding, Stargate Hydrogen plans to scale up manufacturing capacity, expand internal testing capabilities, and establish strategic partnerships with leading players in the global green hydrogen ecosystem. The latest investment brings Stargate’s total committed capital (equity and grants combined) to over €50M.
