EDF Power Solutions is pushing forward with a pioneering offshore hydrogen production initiative in France’s Exclusive Economic Zone, launching a tender for Environmental Impact Assessment (EIA) services and hazard studies. The project, known as HYODE (HYdrogen Offshore DunkerquE), aims to produce green hydrogen using power generated by offshore wind farms near Dunkirk.
HYODE is designed as a pilot-scale system that integrates an offshore electrolyzer with facilities for hydrogen storage and ship-based transport to shore. EDF says the concept represents an innovative pathway to expand green hydrogen production and support broader decarbonization goals in France and across Europe.
With hydrogen expected to play a major role in the energy transition, EDF stresses that tapping all sources of low-carbon electricity—offshore wind included—is essential. Through HYODE, the company aims to demonstrate a new offshore production model that could accelerate the sector’s growth.
The tender covers the development of documentation required for obtaining a single authorization for EEZ-based projects. This includes the environmental impact study, Natura 2000 assessments, and applications related to protected species, as well as support throughout regulatory reviews and public consultations for one or two offshore wind projects.
Applications for the EIA tender are due by December 12, 2025. The competitive process will run from January 12 to April 8, 2026, with the contract expected to begin in April 2026.
