Hydrogen Storage Plant (CEOG), French Guiana

CEOG (Centrale Electrique de l’Ouest Guyanais), currently the greatest project worldwide of a power generating plant storing intermittent renewable energy using hydrogen


Meridiam has been partnering with Hydrogène de France (HDF) – a French company specialized in the development of hydrogen storage solutions, and the SARA – a French company specialized in the distribution of petroleum in French Guiana and the French Caribbean -, to develop this innovative and flagship hydrogen-based project.

The project consists in the development, construction, financing, operation and maintenance of a power plant combining a photovoltaic (PV) Plant with battery and hydrogen storage. The power plant will deliver a firm capacity of 10 MW from 8am to 8pm and 3 MW between 8pm and 8am. The plant will thus generate non-intermittent renewable electricity in the North-West region of French Guiana that faces an important increase in electricity demand.
