German electrolyzer manufacturer Sunfire has been commissioned by Finnish developer P2X Solutions to carry out a Front-End Engineering Design (FEED) study for a 40MW green hydrogen facility in Joensuu, eastern Finland, the companies announced at the World Hydrogen Congress in Copenhagen.

Expansion of finland’s green hydrogen capacity

The project marks Finland’s next major step in scaling up domestic green hydrogen production, following the start-up earlier this year of the country’s first industrial-scale hydrogen plant in Harjavalta. The expansion reflects a broader European effort to accelerate renewable hydrogen supply chains to meet decarbonization targets and reduce reliance on fossil-based fuels in heavy transport and industry.

Feed study and project details

According to P2X Solutions, the Joensuu facility will triple the company’s total green hydrogen capacity once operational. Sunfire’s FEED study will define the technical and integration parameters for a 40MW pressurised alkaline electrolyzer system — a technology noted for its commercial readiness and efficiency in industrial hydrogen production.

“The FEED study is an important milestone towards the investment decision of our next undertaking in Joensuu,” said P2X Solutions’ chief executive Herkko Plit, adding that the collaboration continues the firms’ work in advancing Finland’s hydrogen economy.

Sunfire chief executive Nils Aldag said the new project builds on the successful commissioning of the 20MW Harjavalta plant, the first industrial-scale green hydrogen facility to enter operation in Finland. “I’m excited that we are now taking our partnership to the next level in Joensuu — as a trusted technology partner alongside P2X Solutions, with a clear mission: to drive the growth of the hydrogen economy in Finland and Europe,” Aldag said.

E-methanol production and industrial use

Once completed, the Joensuu plant’s hydrogen output will be used to produce e-methanol — a synthetic fuel seen as crucial for decarbonizing sectors such as shipping and aviation that are hard to electrify.

Finland’s hydrogen sector remains relatively small compared with early movers such as Germany and Norway, but projects like Joensuu signal growing national ambition aligned with the EU’s hydrogen strategy. For Sunfire, the partnership reinforces its presence in the Nordic market amid intensifying competition among electrolyzer manufacturers seeking scale. For investors and policymakers, the development illustrates how industrial partnerships are translating early demonstration projects into larger commercial ventures capable of supporting Europe’s low-carbon fuel transition.
