Ocean Thermal Energy ConversionThe large ocean surface acts as a reservoir of solar energy. The sun warms the surface water and wave motion mixes it to the downward from the deep cold water, formed at high latitudes, by a thermocline. The resulting vertical temperature distribution thus consists of two layers separated by an interface with temperature differences ranging from 10-30 degree Celsius. These two enormous reservoirs act as heat source and heat sink. Now, if a heat source is available at a higher temperature and heat sink at lower temperature, it is possible in principle to utilise this temperature difference to run a prime mover, i.e. turbine. The prime mover converts part of the heat taken up from the source into mechanical energy and hence into electrical energy. The engine working on this principle and utilises ocean energy is referred as OTEC.
