French firm pioneers offshore hydrogen production with Sealhyfe
The French company Lhyfe has launched the world’s first electrolyser operating directly on the open sea. The platform, Sealhyfe, is located in the SEM-REV Centrale Nantes area, near Le Croisic on the Atlantic Ocean.
This innovative installation is the first of its kind globally. Sealhyfe is approximately 10 nautical miles (about 19 kilometres) from the shore near Le Croisic and connected to the SEM-REV Centrale Nantes hub. It has already commenced production of eco-friendly hydrogen.
The pilot programme was initiated to demonstrate that green hydrogen production at sea is viable. The electricity needed for this process is sourced from the FLOATGEN floating wind turbine.
Floating electrolyser at sea
The sea-based electrolyser has a capacity of 1 megawatt and covers an area of just under 200 square metres. It can produce up to approximately 400 kilograms of hydrogen per day.
The technology introduced by Lhyfe has undergone rigorous testing for efficiency and safety, proving it can operate in challenging conditions. The project also aims to minimise the need for frequent equipment maintenance.
Hydrogen production is an ecological future
Producing eco-friendly hydrogen is one of the most promising solutions for sustainable energy in the future. Hydrogen, mainly when produced from renewable sources such as solar, wind, or biomass energy, has the potential to become the clean fuel of the future, aiding in the decarbonisation of industry, transport, and energy.
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," shares Matthieu Guesné, Founder and CEO of Lhyfe. 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, CEO of Lhyfe.
