Ocean thermal energy conversion is a marine based process which generates electrical energy by exploiting the temperature difference between the warmer surface water of the seas or oceans and the colder temperaturers of deeper waters. Ocean thermal energy conversion is a potential source of reliable renewable energy as its sunlight which heats the oceans water with many benefits to the environment creating no harmful emissions. OTEC heat recovert systems operate as cyclic heat engines which uses a working fluid warmed by the seawater to produce a vapour and the cold water to condense the vapour
