McPhy and Siemens Energy sign maintenance agreement

McPhy Energy signed an 8-year maintenance contract with Siemens Energy, acting as the manufacturer and operator of the Western Guiana Power Plant (CEOG) project.

CEOG is the world’s largest power plant project combining photovoltaic energy and massive 128 MWh storage, mainly in the form of hydrogen. It was initiated by Meridiam, Société Anonyme de la Raffinerie des Antilles (SARA) and Hydrogène de France (HDF).

This contract provides the remote planned and corrective maintenance of a high-power electrolyzer and the supply of replacement parts and services to the site.

Under this agreement, McPhy’s teams will manage the maintenance of the equipment used to produce hydrogen and will also provide replacement parts and services to the site starting in 2024. McPhy will ensure the energy availability and efficiency of the electrolyzer.

By combining a high-power electrolyzer, 16 MW Augmented McLyzer supplied by McPhy, a photovoltaic solar park, a hydrogen storage unit and high-power fuel cells, the CEOG plant will produce hydrogen, which will be stored under pressure in tanks.

This hydrogen will then be recombined with oxygen from the air within fuel cells to produce 24/7, non-polluting electricity. The CEOG plant will thus secure the supply of electricity to 10,000 households in French Guiana, at a competitive cost compared to the territory’s thermal power plants.
