The Blue Revolution – ocean of energy in ‘Ocean’ (A review)
Permanent URI for this collection
Ocean thermal energy conversion (OTEC) is a renewable energy technology that is applicable to most parts of the world’s deep oceans between 20⁰ North and 20⁰ South latitude including the Caribbean and Gulf of Mexico, the Pacific, Atlantic and Indian Oceans, and the Arabian Sea, where the temperature difference between the warm surface ocean water and the cold deep ocean water is equal or greater than 20⁰C. In essence, OTEC basically recovers part of the solar energy absorbed by the ocean. Its main application is in tropical zones where deep ocean water is available at short distance from the shore (less than 6 miles or 10 km). In addition, the potential site must have a marine environment that allows the operation of a stable system.
