Estonia’s green energy transition doesn’t stop, with more industrial facilities going online. Last week, Estonian company Stargate Hydrogen opened a cutting-edge factory in Tallinn dedicated to producing alkaline electrolysis systems. Estonian Prime Minister Kristen Michal attended the factory opening, highlighting the project’s national significance and governmental support.
While many hydrogen companies struggle with oversized, underused facilities that drain cash, Stargate Hydrogen has taken a different approach. In its first phase, the new facility can produce 140 megawatts of alkaline electrolysers annually—enough equipment to power significant hydrogen production operations. With relatively small additional investments, capacity could expand to 1 gigawatt (1,000 MW).
The project received funding support from Estonia’s government through emissions trading revenues and has achieved IPCEI status—a European Union designation for projects considered vital to Europe’s strategic interests.
CEO Marko Virkebau explains their modular strategy: “We scale up gradually to meet growing demand, rather than building massive factories that sit idle.” The company’s production is fully booked through the end of 2025, with strong demand from European customers and growing interest from the Middle East and Asia.
Green hydrogen is crucial for decarbonising heavy industries that can’t easily switch to electricity, including:
- Steel production
- Fertiliser manufacturing
- Chemical processing
Thanks to years of dedicated efforts, the company is now well-positioned to tackle those big industries. Founded in 2021, Stargate Hydrogen has raised €50 million from investors and serves customers, including major companies like Fortum, ABB, and Utilitas, across Europe, Turkey, and India.
