DCNS Energies offers customized solutions based on harnessing temperature differences in the ocean and provides made-to-measure projects that vary Designed for islands and isolated areas, this non-intermittent base-load energy source could in the medium-term, provides a green alternative to fossil Ă©nergies (gas, diesel, coal) that are still massively used on remote tropical, which are connected to continental power grids.

This concept based on ocean thermal gradients, will help overseas territories in becoming energy self-sufficient as well as environment friendly.

The thermodynamic cycle (Rankine) produces energy due to the temperature difference between a heat source and a cold source. Ocean Thermal Energy Conversion (OTEC) harnesses the difference in temperature between surface waters (about 25°C) and waters (+0.6 mile deep, about 5°C). Such difference in temperature can be found tropical waters, where electricity can be produced 24/7.

In 2014, DCNS and its partner Akuo Energy have been selected as part of the European NER 300 programme to develop a pilot offshore OTEC plant in the Martinique Island (French overseas territories). Due to be operational in 2020, the 10MW floating power plant NEMO (New Energy for Martinique and Overseas) is designed to supply electricity to 35,000 homes.
