Thanks to the technologies developed in the field of Ocean Thermal Energy Conversion (OTEC), DCNS is able to offer tropical maritime regions that are not connected to the continental networks the possibility of achieving energy independence.

The principle of Ocean Thermal Energy Conversion (OTEC) is based on harnessing the difference in temperature in tropical waters between the surface water, which is at about 25°C, and water at depth, which is at 5°C at a depth of 1,000 metres. This temperature difference allows the continuous production of electricity. In the medium term, OTEC will contribute to addressing the growing electricity needs of regions located in the tropics and ensuring their future energy independence. In effect, this innovative solution is a green alternative to so-called “fossil” energy sources (gas, coal), which are still massively used on isolated sites, not connected to the continental electricity networks.

In 2014, DCNS received European support for the development of a floating OTEC plant in Martinique. This project, called NEMO (New Energy for Martinique and Overseas), is being developed by Akuo Energy in partnership with DCNS, the supplier of this innovative technology. They will build a 16MW plant that could eventually power 35,000 homes.
