(Oslo / Norway) – Norway's DNV Group, a technical advisory, engineering, certification and risk management service provider, will lead a study to examine key environmental, safety and operational risks for the world's first offshore hydrogen production facility. The offshore test site, called “SEM-REV”, is led by Lhyfe, a producer and supplier of green hydrogen, and the French engineering school Centrale Nantes.
The aim is to demonstrate the reliability of an offshore electrolyser. Located off the coast of Le Croisic, France, the green hydrogen production system is expected to be powered by electricity from a floating wind turbine and will be operational in 2022.
The offshore electrolyser will be installed on the GEPS Techno platform and connected to various Marine Renewable Energy (MRE) sources available at the test site, including the Floatgen floating wind turbine. Centrale Nantes also provides research facilities and support for the regulatory, experimental and logistical phases.
As part of the planning of the new facility, DNV will conduct workshops and technical sessions. Fuel cells and hydrogen production are being examined, and regulations and standards are also being reviewed. “Demonstrating the safety of such activities is critical for the industry, especially for new technologies, to gain acceptance and bring them closer to adoption,” says Santiago Blanco, Executive Vice-President and Regional Director Southern Europe, MEA and LATAM , Energy Systems at DNV.
DNV Group is owned by Det Norske Veritas Holding AS, a subsidiary of Stiftung Stiftelsen Det Norske Veritas. As of February 1, 2021, DNV changed its group structure. This consists of six business areas and Veracity as an internal joint venture. Lhyfe offers modular turnkey solutions for green hydrogen production. Founded in 1919, Centrale Nantes is a French engineering school with an international focus on manufacturing, energy transition and healthcare.
The Wavegem platform is a hybrid, autonomous power generation platform designed to provide green power to marine or island facilities without access to the grid. It was developed by GEPS Techno, a company based in the Pays de la Loire region. 
The platform generates energy from wave power through the movements of a swimmer in a closed circuit with seawater. The conversion into electrical energy takes place via a turbine at low speed. The platform was installed on the SEM-REV site in August 2019, beginning 18 months of offshore testing. It is secured with a four-point plastic anchoring system and complements the Floatgen floating wind turbine, which has been on site since spring 2018.
