Ocean Thermal Energy Conversion plant

The Union Ministry of Earth Science’s (MoES) autonomous National Institute of Ocean Technology is building an ocean thermal energy conversion facility.

It is being established in Kavaratti, the capital of Lakshadweep.
It can produce 65 kilowatts (kW).
The project will run the low-temperature thermal desalination plant, which produces 1 lakh liters of drinkable water per day out of seawater.

About Ocean Thermal Energy Conversion

Ocean thermal energy conversion (OTEC) is a type of energy conversion that takes advantage of the temperature difference between the cooler, deeper ocean waters and the warm, surface waters that are heated by solar radiation.

An ordinary heat engine produces power using OTECs.
In addition to producing clean energy, the OTEC process yields several beneficial byproducts.
Air conditioning systems and chilled-soil farming both use the surface delivery of cool water (which allows for the cultivation of temperate-zone plants in tropical environments).
Waters desalination has utilized open-cycle and hybrid technologies, and OTEC infrastructure provides access to trace elements found in deep-ocean seawater.
In addition, water can be electrolyzed to produce hydrogen for use in fuel cells.

Potential: The possibilities for the commercial implementation of OTEC technology appear promising, especially on tropical islands and in underdeveloped nations where operating conditions for OTEC plants are most favourable.
