Lhyfe is a French company focused on the production of renewable (green) hydrogen via water electrolysis powered by wind, solar, and other renewable sources. Founded in 2017 and based in Nantes, it develops, builds, and operates hydrogen plants to supply decarbonized hydrogen for mobility and industrial uses. Its activities span project development, production, and distribution, supplying customers such as transport operators and industrial sites seeking to reduce fossil-based hydrogen consumption.
The company is active across Europe, with onshore facilities in operation and a pipeline of projects at various stages. Lhyfe has also demonstrated offshore production with an electrolyser connected to marine renewable energy (the Sealhyfe pilot). Its hydrogen meets emerging European regulatory frameworks for renewable fuels, supporting applications in heavy mobility, chemicals, refining, and other sectors requiring low-carbon hydrogen.
