HyOffWind reaches new milestone with installed John Cockerill electrolyser stacks

he HyOffWind project in Zeebrugge has reached an important milestone with the delivery and installation of the first electrolyser stacks manufactured by John Cockerill for what is set to become Belgium’s first large-scale renewable hydrogen production facility. Powered by renewable electricity from offshore wind farms, the project will initially operate with a 25 MW electrolyser capacity and is expected to produce around 3,700 tonnes of green hydrogen annually while avoiding approximately 25,000 tonnes of CO₂ emissions per year.  

Developed by Virya Energy together with HyoffGreen and Messer, and built in collaboration with BESIX and John Cockerill, HyOffWind highlights the growing integration of offshore wind and hydrogen production in the Port of Zeebrugge. The installation of the electrolyser stacks marks a key step towards commissioning and demonstrates the progress being made in deploying European-made electrolyser technology at industrial scale. The first hydrogen molecules are expected to be produced in 2026, further strengthening Zeebrugge’s position as an emerging hydrogen hub for industry and mobility applications.
