- Sealhyfe was towed 20 km into the Atlantic and connected to SEM-REV, starting hydrogen production on 20 June 2023.
- The platform, equipped with a 1 MW electrolyser, can produce up to 400 kg of hydrogen daily.
- From September 2022 to May 2023, Sealhyfe underwent trials at the Port of Saint-Nazaire.
- The HOPE project, coordinated by Lhyfe, received a €20 million grant from the European Commission.
Sealhyfe Offshore Hydrogen Production
Lhyfe's Sealhyfe, the world's first offshore hydrogen production pilot, was successfully towed 20 kilometers into the Atlantic and connected to the SEM-REV power hub. On 20 June 2023, the platform began producing its first kilos of green hydrogen, marking a significant milestone for the sector.
Technical Feasibility and Operational Experience
Sealhyfe was designed to meet unprecedented challenges, proving the technical feasibility of offshore hydrogen production. The platform, equipped with a 1 MW electrolyser supplied by Plug, can produce up to 400 kilograms of hydrogen daily. It operates on a floating platform re-engineered to stabilize the production unit at sea and is connected to the SEM-REV offshore testing hub.
Initial Trials and Optimization
From September 2022 to May 2023, Sealhyfe was moored at the Port of Saint-Nazaire for initial trials. These tests allowed Lhyfe to benchmark performance, optimize technology for extreme conditions, and develop software for remote site management. The platform operates autonomously, 20 kilometers off the coast, connected to the SEM-REV subsea hub.
Future Developments and HOPE Project
Following the initial success, Lhyfe announced the HOPE project, coordinated as part of a consortium of nine partners. The project received a €20 million grant from the European Commission under the European Clean Hydrogen Partnership. HOPE aims for commercial-scale production, targeting up to four tonnes of green hydrogen daily at sea, to be exported ashore by pipeline.
Strategic Partnerships
Lhyfe has signed partnership agreements with wind turbine developers and offshore power specialists, including EDPR, Centrica, and Capital Energy, to further its goals in hydrogen production and decarbonization.
