Atlantique Offshore Energy has launched a power system to support the decarbonisation of electrical offshore substations.
During several months of extensive engineering efforts, Atlantique Offshore Energy – the Chantiers de l’Atlantique business dedicated to marine energy – developed an integrated hydrogen emergency power supply solution using new fuel cell technologies.
This concept, SeeOs+H2, replaces conventional diesel back-up generators, and secures the 18 hours of autonomy in emergency mode for platform safety, with no CO2 nor NOx emissions.
The system integrates its own electrolyser and a complete supervision, monitoring and control system.
“We are really happy to contribute to the decarbonization of our customers’ operations and of the offshore wind sector through this kind of pioneering proposal” said Frederic Grizaud, director of Atlantique Offshore Energy.
“This project reflects our capacity to innovate and to implement ready-to-market solutions based on the lessons learned from successful execution of numerous offshore substations”.
