NEMO OTEC
The New Energy for Martinique and Overseas (NEMO) Ocean Thermal Energy Conversion (OTEC) plant was a concept for supplying electricity to the island of Martinique, France. NEMO's design was based on the Rankine cycle using ammonia as the working fluid. It consisted of four process units located in the platform's hull, each one outfitted with a pair of exchangers (evaporator and condenser) and a turbo generator.
The NEMO OTEC system was planned to have eleven intake and discharge sea water pipes built vertically from the platform to reach different depths: one cold water intake pipe to pump water 1,100 m in depth; four warm water intake pipes to pump water 9 m in depth; two cold water discharge pipes with outflows at 150 m in depth (under the photic zone); and four warm water discharge pipes with outflows at 16 m in depth.
