Paris (France) / Nantes (France), 29 November 2021 – Following a 12-month-long joint R&D programme focused on developing economically viable offshore green hydrogen production solutions, DORIS, an integrated engineering and project management group and a leader in offshore technology, and Lhyfe, a world pioneer and pure player in renewable green hydrogen production, have decided to become official partners to step up their work on offshore hydrogen production. Together they plan to launch the first floating wind turbine for integration with a hydrogen production system and identify larger-scale opportunities for their solutions.
In committing to work together under this agreement, DORIS and Lhyfe wish to combine their outstanding technical innovations and excellence in their respective fields of expertise, while fostering a relationship of mutual trust and understanding.
The signing of the MoU by the two companies comes just several weeks after Lhyfe’s Bouin production site in Vendée began producing the first few hundreds kilos a day of carbon-free green hydrogen. The operational knowledge gained from this world first will be employed to finalize the development of DORIS’ and Lhyfe’s proprietary solution NerehydTM. This exclusive product combines Lhyfe’s expertise in green renewable hydrogen production with DORIS’ floating wind turbine solution NerewindTM. The NerehydTM solution, which incorporates a hydrogen production facility into the floater of a wind turbine, could be deployed for on-grid or off-grid applications, from small-scale 10-megawatt wind turbines to large-scale wind farms with several hundred megawatts of capacity.
The budget for the project – including R&D and the production of the first prototype, due in 2025 – will be in the region of 60 million euros.
The objectives of the two partners are to:
- Finalize the solution’s design
- Overcome the main technical and economic obstacles
- Develop and finance a pilot project
- Identify target projects for industrial-scale deployment.
Xavier Grandiaud, Executive Deputy Managing Director of DORIS Engineering said: “While we have no doubts that producing green hydrogen on land will be the first step in large-scale global development, we deeply believe in the need to move rapidly offshore to meet the strong demand ahead, which will require a massive amount of electricity. With Lhyfe, we believe that offshore production will be the best way to successfully produce large amounts of green hydrogen without impacting terrestrial landscapes or relying on an existing grid connection. Our NerehydTM solution is the perfect tool for large-scale, sustainable and economically viable green hydrogen production. With Lhyfe, we now have all the keys in hand to make Nerehyd a success.”
Matthieu Guesné, CEO and founder of LHyfe added: “We are delighted to be moving forward on our projects with DORIS. At Lhyfe, the reason we located our first production site near the ocean was to start producing in offshore conditions, because from day one we have been certain of one thing: offshore is the key to the massive development of renewable hydrogen. We are starting to see more and more offshore wind farms and traditional players are keen to find ways to scale-up their infrastructures and solutions. We are therefore very optimistic about the development of this sector and are working to offer a range of solutions to adapt to each situation”.
In addition to the joint development of NerehydTM, which is the partnership’s core focus, Lhyfe and DORIS will also be studying the possibility of extending the collaboration to other types of offshore hydrogen production solutions.
About DORIS
DORIS is an integrated international group specialized in engineering and project management. As a major player in the energy industry, DORIS provides engineering services as well as technical solutions and products to help energy operators to develop cleaner energy sources.
About LHyfe
Founded in 2017 in Nantes, Lhyfe produces and supplies green and renewable hydrogen for use in the transport sector and industry. Its production sites make it at last possible to source renewable hydrogen in industrial quantities and to deploy a virtuous energy model geared towards environmental friendliness. Lhyfe has entities in German, Sweden, Denmark, the Netherlands and Spain and will soon have in the region of 100 staff. The company is a member of France Hydrogène and Hydrogen Europe. Lhyfe raised 70 million euros in funding between 2019 and 2021 and inaugurated its first industrial green hydrogen production site on 30 September in Vendée.
