Question

list 3 major limitations of ocean thermal energy​

Answer 1

$\huge\bold{Answer}$

$\boxed{\textbf{Ocean Thermal Energy}}$

The water at the surface of the sea or ocean is heated by the sun, while the water in deeper sections is relatively cold.

This difference in temperature is known as $\bold{Ocean \: Thermal\: Energy}$

This devices used to harness this form of ocean thermal energy are known as $\bold{Ocean \: Thermal\: Energy\:Conversion}$

The warm surface water is used to boil a volatile liquid like ammonia.

The vapours of the liquid are then used to run the turbine of the generator.

The cold water from the depths of the oceans is used to condense vapour again to liquid.

The energy potential from the sea is quite large but efficient commercial exploitation is difficult.

$\textbf{\underline{Limitations}}$

● These power plants can operate only if the temperature difference between the surface and water at depths upto 2km is 293k (20°) or more.

● It is expensive and less efficient.

● It Requires more space and high voltage.
