Sea energy can be converted into electricity in 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 exploited to obtain energy in ocean-thermal energy conversion plants.
- These plants can operate if the temperature difference between the water at the surface and water at depths up to 2 km is 293 K (20°C) or more. 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 depth of the ocean is pumped up and condenses vapour again to liquid.

Sea energy can be converted into electricity in ocean-thermal-energy-...
Temperature difference is crucial for energy conversion:
The correct answer is option 'A' because the temperature difference between the water at the surface and water at depths up to 2 km needs to be at least 20°C (293 K) for effective ocean thermal energy conversion. This temperature gradient is essential for driving the process of converting sea energy into electricity.
Explanation:
- Ocean thermal energy conversion plants utilize the temperature difference between warm surface water and cold deep water to generate power.
- The greater the temperature difference, the more efficient the conversion process will be.
- A temperature difference of 20°C or more provides the necessary energy to drive the turbines and produce electricity.
Importance of temperature gradient:
- The temperature gradient is a critical factor in determining the feasibility and efficiency of ocean thermal energy conversion plants.
- Without a significant temperature difference, the process will not be able to generate sufficient power to be economically viable.
Conclusion:
In conclusion, the key factor for the successful conversion of sea energy into electricity in ocean thermal energy conversion plants is the presence of a substantial temperature difference between surface water and deep water. This temperature gradient is essential for driving the process and ensuring the efficient generation of electricity.
