Question

State the principle of working of ocean thermal conversion plant.

Answer 1

OTEC uses the principle of a heat engine. It works by converting a temperature difference into energy. This means the difference in temperature between the warmer water on the surface and the cooler water in the depths of the ocean can be converted into electricity.

Answer 2

First we need to know conditions for thermal conversion-

Temperature of water at the surface of ocean and at deeper levels (at depth upto 2 km should be 20C or more.
