Ocean thermal energy conversion facts.

Ocean thermal energy conversion otec uses the temperature difference that exists between deep and shallow ocean water to run a heat engine. Ocean thermal energy conversion otec systems use a temperature difference of at least 77 fahrenheit to power a. Although this temperature difference generally. Most of the time it is shortened as otec.

Ocean thermal energy conversion otec form of energy conversion that makes use of the temperature differential between the warm surface waters of the oceans heated by solar radiation and the deeper cold waters to generate power in a conventional heat engine. The difference in temperature between the surface and the lower water layer can be as large as 50 c 90 f over vertical. Ocean thermal energy conversion otec uses the ocean thermal gradient 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 can operate with a very high capacity factor and so can operate in base load mode. If a pipe is put down into the ocean we can bring the.

This temperature difference can be used to produce electricity and to desalinate ocean water. Pipes are used to bring large volumes of colder water up from the depths while warmer water is also drawn into the otec plant from the ocean surface. Ocean thermal energy conversion is one of the renewable energy sources in the world. Energy from the sun heats the surface water of the ocean.

The energy is gained from the different temperature in the ocean. Together the warm ocean surface and the cool deep water can generate heat. Ocean thermal energy conversion otec is a way of getting useful energy from the world s oceans the sun shines on the oceans of the world and in the hot parts near the equator the water at the sea s surface can be quite warm sometimes as high as 30 c.
