Question

What are the advantages and disadvantages of ocean thermal energy?

Answer 1

Advantages of OTEC system :

• Power from OTEC is continuous, renewable, and pollution-free.
• Unlike other forms of solar energy, the output of OTEC shows very little daily or seasonal variation.
• Drawing of warm and cold seawater and returning
• the seawater, close to the thermocline, could be accomplished with minimal environmental impact.

Disadvantages of an OTEC system

1. Capital investment is very high.
2. Conversion efficiency is very low about 3-4% due to the small temperature difference between the surface water and deep water
3. The low efficiency of these plants coupled with high capital cost and maintenance cost makes them uneconomical for small plants.
