Pioneering offshore hydrogen plant launches in Atlantic waters
The French company Lhyfe has launched the world's first electrolyzer operating directly on the open sea. The platform, called Sealhyfe, is located in the SEM-REV Centrale Nantes area, near Le Croisic on the Atlantic Ocean.
This innovative installation is a world first. Sealhyfe is about 19 kilometres from the shoreline near Le Croisic and connected to the SEM-REV Centrale Nantes hub. It has already begun producing eco-friendly hydrogen.
The pilot program was launched to demonstrate that green hydrogen production at sea is feasible. The FLOATGEN floating wind turbine supplies the electricity required for this process.
Floating electrolyzer at sea
The sea-based electrolyzer has a capacity of 1 MW and covers an area of just under 200 square metres. It can produce up to about 400 kilograms of hydrogen per day.
The technology introduced by Lhyfe has undergone thorough testing regarding efficiency and safety. It is capable of operating under harsh conditions. The project also aimed to reduce the need for frequent equipment maintenance.
Hydrogen production is an ecological future
Producing eco-friendly hydrogen is one of the most promising solutions for the future of sustainable energy. Hydrogen, especially when produced from renewable sources such as solar, wind, or biomass energy, can become the clean fuel of the future, helping to decarbonize industry, transportation, and energy sectors.
Our team has designed this first floating green hydrogen production site. We are extremely proud to be the first in the world to produce hydrogen at sea. This has been our wish since the launch of the company and we continue to move very quickly offshore, which for us represents a tremendous development opportunity for mass producing hydrogen and decarbonising industry and transport, says Matthieu Guesne, CEO of Lhyfe.
