McPhy Energy, specialized in low-carbon H₂ production and distribution equipment (electrolyzers and refueling stations), announced the signing of an 8-yr maintenance contract with Siemens Energy, acting as the manufacturer and operator of the Western Guiana Power Plant (CEOG) project, which was initiated by Meridiam, Société Anonyme de la Raffinerie des Antilles and Hydrogène de France.

Under this agreement, McPhy’s teams will manage the maintenance of the equipment used to produce H₂ and will also provide replacement parts and services to the site, starting from 2024. McPhy will ensure 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 H₂ storage unit and high-power fuel cells, the CEOG plant will produce H₂ which will be stored under pressure in tanks. This H₂ 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.
