Stargate Hydrogen, a Tallinn, Estonia-based manufacturer of electrolyser stacks and systems, raised €11M in Series A funding.
Bakers included Giga, UG Investments and SmartCap Green Fund, bringing the total committed capital (combined equity and grants) to $50M.
The company intends to use the funds to scale its manufacturing capacity, expand its internal testing capabilities, and establish key strategic partnerships with players in the global green hydrogen ecosystem.
Led by CEO Marko Virkebau, Stargate has developed proprietary stack technology, focused on increasing the reliability of hydrogen production across the project lifecycle and minimizing the degradation of the equipment. Those innovations improve the unit economics of its products and raise the return on investment for the green hydrogen project developers.
The performance of Stargate stacks has been validated by ZSW in Stuttgart, a test center of electrolysis equipment in Europe.
Customers include Fortum, Utilitas, and ABB.
