Our impact

Hydrogen Storage Plant (CEOG), French Guiana


Meridiam is 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 of 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 10MW from 8AM to 8PM and 3MW between 8PM and 8AM. The plant will therefore generate non-intermittent renewable electricity in the North-West region of French Guiana, which faces an important increase in electricity demand on a geographically constrained territory.

ESG/SDG Key Facts

The project represents a major step in the deployment of a new generation of non-intermittent renewable power plants, therefore offering an alternative to fossil fuel with guaranteed power.
With the support of environmental and regulatory advisors, a detailed environmental study was performed to implement mitigation measures to reduce the environmental impact of the project. Community benefits (tripartite convention and endowment fund) in relation to forest land use are being assed together with the French authorities and the local Amerindian community and the Bushinengués, living in a village located 1.6km from the project.  Agreements with some local villages have been reached, with others ongoing.
