French utility ENGIE and Danish renewables developer European Energy have signed a cooperation agreement to jointly develop a 150 MW renewable hydrogen project at Kassø in Aabenraa Municipality, Denmark. The deal, announced June 9, 2026, gives ENGIE the marketing rights to more than 20,000 tons of renewable hydrogen per year and slots the facility into Europe's emerging Danish-German hydrogen backbone.
A 150 MW Electrolyzer Beside An E-Methanol Plant
The Kassø site is already home to the world's first industrial-scale e-methanol plant, jointly owned by European Energy and Mitsui & Co. ENGIE and European Energy will now develop an adjacent electrolyzer of up to 150 MW, targeting commercial operations around 2030 in line with the expected commissioning of Denmark's hydrogen pipeline to Germany. Hydrogen from the site is earmarked for hard-to-abate industrial and mobility customers in Germany.
Backed By €228M From Germany's Hydrogen Bank Auction
The project was recently selected under the German Auctions-as-a-Service (AaaS 25) scheme tied to the European Hydrogen Bank, securing up to €228 million in support. European Energy says the funding is critical to underwriting capex while ENGIE provides the offtake muscle: "The Kassø project will enable ENGIE to strengthen its offering to its German clients from 2030 onwards," said Henri Domenach, ENGIE's Managing Director of Energy Management.
European Energy Doubles Down On Power-to-X
Rene Alcaraz Frederiksen, European Energy's EVP and Head of Power-to-X, called the partnership "an important role in connecting renewable energy production with industrial decarbonisation across Europe." The deal extends a Power-to-X build-out that already includes Kassø's e-methanol facility and the company's broader pipeline of wind- and solar-powered electrolysis. It also follows a wave of European hydrogen tenders, including Sunfire's 50 MW HyLink Alkaline 23 launch aimed at industrial buyers.
Why Cross-Border Pipelines Matter
The Kassø plant only pencils out at scale because Denmark and Germany are jointly building hydrogen transport infrastructure that can move molecules across the border. Without it, the project would be stranded next to demand it cannot reach. Other European developers are racing along similar lines, including in the UK where University of Birmingham's perovskite catalyst aims to cut electrolyzer operating temperatures, and in Asia where Toyota and Hyroad are scaling hydrogen trucking in California.
