ENHANCED OCEAN THERMAL ENERGY CONVERSION (EOTEC) SYSTEM

Resumen de: WO2024155333A1

An improved Ocean Thermal Energy Conversion system (called OTEC) is presented herein by the addition of a closed heat transfer loop. In conventional OTEC, warm surface waters are used to vaporize a working fluid for use in a turbine, and cold waters are then brought up from deep water, typically more than 1000 meters, to condense the working fluid. In simple terms conventional OTEC brings the cooling potential up to the warm surface. The disclosed OTEC system brings the heat down to the deep cold waters by using a separate heat transfer fluid loop. We refer to this as Enhanced OTEC or E-OTEC. A key feature of the process is descending to the depths as a dense fluid and returning to the surface as a much lower density fluid, thereby gaining a gravitational boost in pressure and temperature. This leads to several technological, performance, and economic advantages over prior art.
