Lhyfe gains RFNBO certification of three European sites

Lhyfe said it has confirmed its position as a European leader of RFNBO hydrogen production from water electrolysis with the certification of its three additional installed sites in France and Germany.

RFNBO certification is the European Union’s most stringent standard for green hydrogen under the European Renewable Energy Directive (RED III). It certifies that Lhyfe’s hydrogen production at these three sites is 100% renewable and complies with the environmental and traceability criteria that must be met by sustainable activities under the EU Taxonomy.

Lhyfe’s RFNBO-certified installed sites now include:

• Certified in May 2025, Bouin (1 MW) in the Pays de la Loire region is said to be the world’s first hydrogen production site connected to a wind farm and the first French site to be RFNBO certified.
• Buléon (5MW) in Bretagne, and Bessières (5MW) in Occitanie, are 5-MW sites, representing the largest production sites in France to date, said Lhyfe.
• Schwäbisch Gmünd (10 MW), in Baden-Württemberg (Germany), is Lhyfe’s largest site to date and Germany’s second-largest RFNBO hydrogen production site. This site will be officially inaugurated in October 2025.

These sites represent a total installed capacity of 21 MW and a production capacity of up to 8.3 tonnes of green hydrogen per day. According to the company, this makes it the largest producer in Europe of RFNBO hydrogen from the electrolysis of water (in terms of installed capacity and number of sites), and the only RFNBO-certified producer in France.

Dedicated to bulk production, the sites will be able to deliver to customers throughout Europe. The RFNBO hydrogen is being supplied for current applications in mobility and industry, as well as to carry out a variety of tests, for example, for combustion, salt cavern hydrogen storage, mixed boilers, construction machinery, etc.

“This certification is a key milestone – it validates the robustness of our industrial model, confirms our technological and regulatory lead, and above all proves that local production of truly renewable and traceable hydrogen is now possible on a large scale in Europe,” said Matthieu Guesné, founder and CEO of Lhyfe. “We are proud to continue leading the way and accelerating the development of renewable hydrogen in France and Europe, ultimately contributing to our decarbonization and energy sovereignty.”

Lhyfe recognized the support of its partners Atmen, CertifHy and Tüv Süd in obtaining the additional certifications.
