SUMMARY
- Stargate Hydrogen, a manufacturer of innovative electrolyser stacks and systems, announces the successful completion of its series A funding round, raising 11 million Euros in equity investments from strategic customers and financial investors.
- Stargate Hydrogen is a leading innovator in the field of sustainable energy solutions, dedicated to advancing the production and utilization of green hydrogen through cutting-edge ceramic-based electrolysis technology.
Affordable green hydrogen is the key to decoupling the production of chemicals and commodities (like steel) from CO2 emissions. Stargate Hydrogen is developing reliable production equipment that will radically bring down the cost of green hydrogen by operating at higher efficiency compared to the existing solutions.
Instead of precious metals, Stargate is using ceramic-based catalyst material that allows to lower energy consumption while keeping the investment needs low.
Stargate has developed a 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 the company's 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 leading test center of electrolysis equipment in Europe. The company’s proprietary technology has been recognized by the European Commission as an Important Project of Common European Interest. Recently, Stargate was selected by Fortum, a major Nordic utility company, as the supplier for its alkaline electrolysis plant in Loviisa, Finland.
The financing round includes strategic customers with backgrounds in renewable energy and utilities such as Giga and UG Investments, accompanied by SmartCap Green Fund, a state-backed venture capital fund investing in greentech companies with global ambitions.
Marko Virkebau, CEO of Stargate Hydrogen said"We are thrilled to have SmartCap and Giga joining our ownership structure, along with additional investment from UGI, To have strategic customers investing into the company is the strongest testament to the progress we made. 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. Our view is that only companies with unique, proprietary technology will survive through the current green hydrogen market cycle".
Sille Pettai, CEO of SmartCap and manager of SmartCap Green Fund, funded by the European Union’s NextGenerationEU said, “We decided to invest in Stargate Hydrogen due to their highly innovative approach to green hydrogen production, accompanied by an impressive list of customers and strong unit economics. Funding the scale of manufacturing of innovative green technologies is central to the green transition and our strategic objectives, as it enables wider adoption of sustainable energy solutions,”.
With this funding, Stargate Hydrogen will scale its manufacturing capacity, significantly expand its internal testing capabilities, and establish key strategic partnerships with the leading players in the global green hydrogen ecosystem.
