Question

Q5) hat is ocean thermal energy and what are the limitations of the energy obtained from it ?

Answer 1

The thermal energy difference between cooler deep water and the warmer surface water of ocean can be used to run heat engine and produce useful work in the form of electricity. This thermal energy of ocean is called ocean thermal energy.

The technology to use the ocean thermal energy is still under development. The main challenge in the use of ocean thermal energy is the low temperature difference between the warm and cold ocean water. Due to this the ocean thermal energy conversion engines are only 1 to 3 % efficient.
