Lhyfe leads the world’s first production of hydrogen at sea with wind power
Lhyfe, the French company that was one of the first in the world to produce hydrogen at sea using wind power, is now expanding its investments in Sweden with several large projects. The largest, a 600 MW project in Söderhamn, will use wind power from Skyborn Renewables. The project is expected to be completed after 2030 and will contribute significantly to Sweden’s energy transition.
Focus on Trelleborg and Ånge
Since 2020, Lhyfe has been active in Sweden. Right now they are building a 10 MW electrolyser in Trelleborg. It will produce four tons of green hydrogen per day for heavy traffic and will be commissioned in 2027. At the same time, they are running an even bigger project in Ånge. Together with OX2 and Velarion, they are developing a 300 MW plant. The goal is to create an industrial cluster where green hydrogen produces ammonia, an important component in artificial fertilizers. The wind farm in Marktjärn will supply 1.1 TWh of electricity per year to the project.
Sealhyfe – the world’s first offshore hydrogen platform
Lhyfe paves the way for future offshore projects with experiences from Sealhyfe, their first offshore hydrogen platform. Sealhyfe produced hydrogen at sea using floating wind power, stationed off the French coast for six months, despite severe weather conditions.
Efficient production with PEM technology
To manage the uneven electricity supply from wind power, Lhyfe used PEM technology in Sealhyfe. The technology enables rapid adjustments to production. During the project, the platform withstood storms with winds over 150 km/h and waves of ten meters. Thanks to that technology, production worked well and proved that large-scale offshore hydrogen production is feasible.
The next step – the North Sea and the EU project Hope
Now Lhyfe is taking the next step in the North Sea with the Hope project, which the EU finances. They are to install a 10 MW electrolyser on a converted oil platform. The goal is to create an entire value chain, where the hydrogen is led in a pipeline to land for purification and compression. The project starts in 2026 and includes several European companies.
Research in the Baltic Sea
Lhyfe does not yet have concrete projects in the Baltic Sea, but they are participating in a research project with Stockholm University. They are investigating the possibility of using oxygen from hydrogen production to oxygenate oxygen-poor bottom areas. This can improve the ecosystem in the Baltic Sea and provide environmental benefits.
