Grenoble, October 13th, 2023 – 8:00 am CEST – McPhy Energy, specialized in low-carbon hydrogen production and distribution equipment (electrolyzers and refueling stations), today announces the lift of the CEOG project suspension which was formally notified by Siemens Energy.

As a reminder, the CEOG project includes the production of hydrogen thanks to a high power electrolyzer, Augmented McLyzer 16 MW, supplied by McPhy, linked to a solar photovoltaic park, coupled with a hydrogen storage unit and high-power fuel cells to reduce the carbon footprint related to the supply of electricity to 10,000 households in French Guiana.


This resumption follows the suspension by the customer of the execution of its order, announced in April, which resulted in the delay of the CEOG project and postponement of the supply of the electrolyzer by McPhy. Following this lift, McPhy has taken actions to resume the project execution and to provide the full supply of its equipment within the second half of 2024.
