Lhyfe and Chantiers de l’Atlantique have signed a Memorandum of Understanding for the development of offshore hydrogen production platforms.


Lhyfe is active in the green hydrogen space. The company, whose green hydrogen production plants are directly interconnected with renewable energy sources to supply local industry and transportation, already has 93 projects in development for production plants in Europe, equating to more than 4.8 GW of total installed capacity. It inaugurated a first industrial production plant in September 2021 and twenty of its projects are at an advanced stage of development (i.e. tender ready, awarded or in construction), representing a total 380.5 MW, due to be operational between 2023 and 2026.


Chantiers de l’Atlantique, via its Marine Energy & Engineering business unit (Atlantique Offshore Energy) has delivered several offshore electrical substations for offshore wind farms. The company has worked on the production of offshore hydrogen production over the last three years, to reduce the environmental footprint of the power substations designed and built in Saint-Nazaire.


This agreement comes as Lhyfe and Chantiers de l’Atlantique, who have already been working together for 18 months as part of the SEM-REV project on the co-development of a pilot system for offshore hydrogen production, prepare to launch the world’s first offshore renewable hydrogen production demonstrator in September 2022, off the coast of Saint-Nazaire (France).


The two companies wanted to reinforce their partnership to deploy the system on a large scale. Lhyfe and Chantiers de l’Atlantique will collaborate on offshore renewable hydrogen production projects with on-grid or off-grid wind farms. Chantiers de l’Atlantique will design, build and install the platforms, while Lhyfe will be in charge of the design and operation of the renewable hydrogen production facilities.


This agreement also covers port areas as well. For offshore projects, the two partners plan to develop production solutions with a minimum capacity of 100 MW, which will be installed on existing fixed structures, or mounted on seabed foundations or floating platforms.


Thomas Créach, Lhyfe’s Technical Director, said: “We are delighted to take this new step forward with Chantiers de l’Atlantique. Thanks to the complementarity and solidity of our expertise, and based on our previous achievements, we are now in a position to respond to the various calls for tenders related to offshore. The production of renewable green hydrogen on a very large scale is now within reach!”  


For Frédéric Grizaud, Director of the Marine Energy & Engineering Business Unit (AOE), Chantiers de l’Atlantique, added: “The signing of this agreement is the concrete materialization of a successful collaboration between two companies with a desire to play a full role in energy transition. We are now in a position in France to offer green hydrogen production solutions for the international market.”.
