Ocean thermal energy conversion 海水温差发电
(重定向自OTEC)
Ocean thermal energy conversion (OTEC) uses the temperature difference between cooler deep and warmer shallow or surface seawaters to run a heat engine and produce useful work, usually in the form of electricity. OTEC is a base load electricity generation system. However, since the temperature differential is small, the thermal efficiency is low, making its economic feasibility a challenge.
