Plans have been unveiled to test a floating wind-to-green hydrogen facility off the coast of Le Croisic in Brittany, France
The floating wind-to-green hydrogen project is being developed by hydrogen and electrolyser company Lhyfe and engineering school Centrale Nantes. The electrolysers for the project will be powered by electricity from a Floatgen floating wind turbine. The project at SEM-REV, Centrale Nantes’ offshore test site, is due to become operational in 2022.
The project, to be developed in collaboration with Chantiers de l’Atlantique, will be used to validate the concept of offshore hydrogen production before moving to a larger scale industrial-size project.
Lhyfe and Chantiers de l’Atlantique have been working together since 2020 on detailed design of an offshore hydrogen production platform that would be built at Chantiers de l’Atlantique in Saint-Nazaire. They believe a platform of 10 MW to several hundred MW of green hydrogen capacity is possible and could be deployed by 2024.
The project partners said they hope the green hydrogen plan will foster the development of a hydrogen industry in the region. It is being supported by the Pays de la Loire Region, the innovation cluster Pôle Mer Bretagne Atlantique and the Maritime Industry Strategic Committee.
The electrolyser will be installed on a floating platform from GEPS Techno and connected to a number of sources of green energy, including the Floatgen floating wind turbine.
Lhyfe founder and chief executive Matthieu Guesné said, “We are convinced that offshore production of renewable hydrogen is suited to the massive deployment of hydrogen that is on the horizon. We are determined to be the first in the world to deploy a solution for offshore renewable hydrogen production.”
The project partners noted that wind power – particularly offshore wind – is a particularly well-suited to green hydrogen production because of its high capacity factor and massive development potential.
“Offshore wind offers the greatest potential for sustainable hydrogen production because of the cost-effectiveness that can be achieved through scalability and technological innovation,” they said.
The SEM-REV site at Central Nantes was connected to the grid in 2012. Since then, it has been used to test two prototypes. It was used to test the Floatgen turbine from 2018 and a wave energy platform, Wavegem, from 2019. The SEM-REV site is also due to host a 5-MW floating wind turbine developed by Eolink in 2022.
