Renewable ocean thermal energy

Wave power, tidal power, municipal solid waste, gas from animal wastes (biogas), landfill, peat energy and ocean thermal energy conversion (OTEC) are the other renewable energy sources (RES). Water energy sources are hydropower, tidal and wave technologies. 

The ocean thermal energy conversion (OTEC) is an energy technology that converts solar radiation to electric power. OTEC systems use the ocean s natural thermal gradient to drive a power-prodncing cycle. As long as the temperature between the warm strrface water and the cold deep water differs by about 20 K, an OTEC system can produce a significant amormt of power. The oceans are thus a vast renewable resomce, with the potential to help tts produce billions of watts of electric power.

It is used as a cooling liquid in the large refrigerators of warehouses and ships. It has even been considered for use in heat exchangers for the recovery of renewable energy, especially for Ocean Thermal Energy Conversion OTEC (see Section D.3.4). 

All these circumstances have lead the industry to begin searching for a new source of energy an alternative and completely petroleum-independent power source. Several technologies are being researched, such as biomass (bio-diesel, ethanol), renewable ocean sources (wave, tidal, and thermal), hydrogen, and many more. 

Renewable Energy Resources Energy resources that are naturally replenishing but flow-limited. They are virtually inexhaustible in duration but limited in the amount of energy that is available per unit of time. Renewable energy resources include biomass, hydro, geothermal, solar, wind, ocean thermal, wave action and tidal action. 

Development of other non-fossil fuel energy sources, such as geothermal, solar, wind and ocean thermal systems will undoubtedly broaden the scope of application for electrolytic hydrogen — perhaps not because they represent a source of low cost electrical power, but because it represents the most attractive means for providing a transportable fuel from these renewable resources. 

In the next 20 years, hydrokinetic power drawn from the earth s oceans and rivers could account for more than 10% of the world s global electricity market (Wood, 2010). The renewable energy resources from ocean wave, tidal stream, ocean and river current and ocean thermal resources are expected to be the major growth area over the next decade (Marsh, 2009). 

Renewable energy is energy generated from natural resources—such as sunlight, wind, water (hydro), ocean thermal, wave and tide action, biomass and geothermal heat—that are naturally replenished and thus renewable. Renewable energy resources are virtually inexhaustible— they are...
