Tallinn-based Stargate Hydrogen has raised €11M in Series A funding to scale up production of its precious metal-free electrolysers. The round was backed by Giga, UG Investments, and SmartCap Green Fund, alongside other strategic customers and investors.
Stargate’s breakthrough lies in using ceramic-based catalyst materials instead of precious metals — delivering higher efficiency, lower energy use, and reduced costs. Their proprietary stack technology also improves reliability across the lifecycle of hydrogen projects, increasing returns for developers.
The company’s innovation has been validated by ZSW Stuttgart and recognised by the European Commission as an Important Project of Common European Interest (IPCEI). Customers already include Fortum, which recently selected Stargate for its alkaline electrolysis plant in Finland.
This funding will help Stargate scale manufacturing, expand testing, and grow strategic partnerships worldwide. It also complements Estonia’s broader hydrogen ambitions — with the country working toward the world’s first nationwide Hydrogen Valley, aiming to produce up to 40,000 tonnes of green hydrogen annually by 2030.
CEO Marko Virkebau calls the investment a strong vote of confidence: “To have strategic customers investing is the strongest testament to the progress we’ve made. This funding gives us the firepower to execute our roadmap and significantly reduce the cost of green hydrogen.”
With this round, Stargate’s total committed capital — equity and grants combined — now exceeds €50M. 🌍⚡️
