Question

name three forms in which energy from ocean is made available for use what are OTEC power plant? how do they operate?​

Answer 1

Dude here is ur answer

Hope it helps..

Three forms of energy found in ocean are

Ocean thermal energy

Tidal energy

Wave energy

OTEC PLANT USES AND PRINCIPLE

Ocean Thermal Energy Conversion (OTEC) is a marine renewable energy technology that harnesses the solar energy absorbed by the oceans to generate electric power

OTEC uses the ocean’s warm surface water with a temperature of around 25°C (77°F) to vaporize a working fluid, which has a low-boiling point, such as ammonia. The vapor expands and spins a turbine coupled to a generator to produce electricity. The vapor is then cooled by seawater that has been pumped from the deeper ocean layer, where the temperature is about 5°C (41°F). That condenses the working fluid back into a liquid, so it can be reused. This is a continuous electricity generating cycle.

Answer 2

(i) Tidal energy

(ii) Ocean waves energy

(iii) Ocean thermal energy

OTEC power plants are ocean thermal energy conversion plants. For operating OTEC temperature difference of 20° or more between the surface water of ocean and inside water of ocean is required to boil liquid like ammonia or chlorofluorocarbon (CFC). The vapors of the liquid at high pressure used to rotate the turbine of the generator to produce electricity.
