Inside Elcogen’s Bold Bet on Hydrogen Power

Elcogen’s new Estonia plant boosts Europe’s hydrogen supply chain with large-scale fuel cell and electrolyser production

17 Oct 2025

Europe’s hydrogen ambitions are shifting from plans to production. On 17 September 2025, Elcogen officially opened its 360 megawatt solid oxide fuel cell facility in Estonia, a €50 million investment that ranks among the continent’s largest in hydrogen technology.

Set in the Loovälja Industrial Park near Tallinn, the 14,000 square meter plant will manufacture solid oxide fuel cell and electrolyser components such as cells, stacks, and modules. These parts power systems that either generate electricity from hydrogen or produce hydrogen from water. The goal is to strengthen Europe’s clean energy supply chain and cut dependence on imported technology.

“This factory marks the turning point from innovation to industrialization,” said CEO Enn Õunpuu. “We’re ready to meet growing demand for efficient and reliable hydrogen solutions.”

Analysts say production will ramp up gradually until the facility reaches its 360 MW annual capacity. Once there, it could serve a wide range of applications, from powering heavy industry and transport to supplying decentralized energy systems.

Still, competition in the hydrogen market is heating up. Developers across Europe are racing to scale manufacturing and drive down costs. Elcogen’s dual focus on both solid oxide fuel cells and electrolysers gives it a foothold in a fast-moving field central to net-zero goals.

For Europe, the opening in Tallinn is more than a ribbon cutting. It marks a step toward energy self-sufficiency and industrial-scale hydrogen production, a vision no longer confined to the future but taking shape in steel, stacks, and the steady hum of a new factory floor.
