French Guiana region to install one of the world’s largest power station with 140 MWh renewable energy storage

Hydrogène de France (HDF Energy) has announced the launch of a world first in the history of renewable energy with the creation of its CEOG project (French Western Guiana Power Plant). The project harnessed via HDF Energy’s Renewstable® solution will deliver 100% clean, affordable and reliable power 24/7 – with no fluctuations and at reduced costs – to an area of more than 10,000 households beset with energy delivery issues.

The project is backed by a EUR 90 million investment from the company, private investment partners and leading banks.

HDF Energy is the world’s first producer of a stable electricity supply based on intermittent energies. The Renewstable® solution combines a 55 MW solar farm with one the world’s largest renewable energy storage solution to provide breaking 140 MWh, based on hydrogen. This is supported via secondary storage in the form of batteries.

The CEOG will address the crucial need to generate clean, reliable energy and will yield economic benefits for French Guiana. With coordination from public agencies in French Guiana, the plant will belocated in a territory hampered by electricity production resources (currently a 20 MW deficit). The Renewstable® solution will boost the electricity grid for 20 years, by providing a reliable energy source at a lower price than the current real cost of production in Western Guiana, and without any subsidies.

The CEOG does not use any fuel or combustible material, which means that it does not use any supply logistics, unlike traditional plants. As for the storage of hydrogen, HDF Energy is proficient in the use of technologies supporting mass storage of energy at a competitive price so that it can be redistributed over a long period (all night and on days with little sunshine and wind). This plant only uses water and sunshine, and only releases oxygen and steam.

The CEOG will be installed in Mana municipality. Connected to the EDF station in Saint-Laurentdu-Maroni, it will generate a fixed electrical output every day of 10 MW a day until evening and of 3 MW during the night. With the stable production of electricity guaranteed, the service provided by the CEOG will be the same as that of traditional plants, the difference being that there will be no greenhouse gas emissions.

The project is scheduled to start in summer 2019, with commissioning planned for autumn 2020. The CEOG project will create around 100 jobs during the construction phase, with around 30 permanent jobs which cannot be relocated during the 20 years of the plant’s operation.
