Ocean Thermal Energy Conversion (OTEC) is a process that converts the thermal energy in ocean water into useful forms of energy, such as electricity. OTEC plants use the temperature difference between the warm surface waters of the ocean and the cooler deep waters to power a turbine, which in turn drives an electrical generator. OTEC plants can be used to generate electricity, desalinate water, and provide cooling for buildings and industrial processes.
Some of the emerging trends in Ocean Thermal Energy Conversion (OTEC) include the use of closed-cycle systems, the use of floating platforms, and the use of deep-sea resources.
