Lhyfe is standing out to sea

Dernière mise à jour : 28 sept. 2020

The green hydrogen producer and supplier announces three R&D partnerships to launch its offshore deployment.

Nantes, June 30th 2020 – Lhyfe, the producer and supplier of green hydrogen, announces its partnership with three leading players in research and development: the CEA, the Marine Energy Alliance (Interreg North-West Europe) and the Institut de Recherche pour le Développement (IRD). With these contracts, Lhyfe keeps on pushing the advances of the technology of its production sites and is preparing its offshore deployment.


Launched in June 2020, the innovations developed under the contract with the CEA Tech will be implemented at Lhyfe’s first green hydrogen production site in Bouin (Vendée) in early 2021. The technologies developed in real-world conditions will allow to validate all the developments made (design of H2 system, management of the wind production) before considering a deployment at sea from 2022.

The European consortium Marine Energy Alliance (MEA)

Set up for 4 years, from May 2018 to May 2022, with a total budget of €6 million, MEA intends to allow European research centres specialized in marine renewable energy (MRE) and industrialists to bring their innovative technologies to advanced technology and commercial readiness levels (TRL/CRL). The companies benefit from from tailor-made services to reach their goals and contribute to the consistent growth of the marine energy industry in general. They have access to the global expertise of the project partners in the development of marine energy.

According to the European Interreg North-West Europe programme, Lhyfe’s application was selected by the MEA through the development of prototypes. In co-management with the Dutch Marine Energy Center (DMEC, Netherlands), Lhyfe will benefit from the scientific and commercial support of the Ecole Centrale de Nantes, EMEC (UK), Marei (Ireland) and INNOSEA (France).


The collaboration contract between the Institut de Recherche pour le Développement (IRD) and Lhyfe aims at studing, upstream, the global environmental effects of oxygen release into the ecosystem, made possible thanks to a deployment of offshore green hydrogen production by water electrolysis. Through research carried out within the IUEM (European Institute for Marine Studies), climatological analysis, carried out using models used by the IPCC, will be undertaken according to two preliminary scenarios (up to 2100): one dimensioning, the other one minimalist, which will make it possible to optimize the strategy of deployment for offshore hydrogen production capacities, in order to maximize the benefit for the ecosystem.

To learn more about Lhyfe’s offshore deployment and offshore wind hydrogen production, RDV on July 2nd. Lhyfe take part of the webinar “Renewable marine energies and power-to-X” organized during the Scientific Day in collaboration with ANCRE, WEAMEC, France Energies Marines et Centrale Nantes, the GDR CNRS EMR -

Matthieu Guesné, founder of Lhyfe :

« These partnerships are a sign of the growing interest that European programmes and actors have in Lhyfe’s ambitions. Because we are convinced that the way of the great sea is the perfectly appropriate solution, we are determined to be the actors of tomorrow of its implementation ».
