In the year 1881, presented a French engineer named Jacques D'Arsonval Ocean Thermal Energy Conversion or OTEC. On the other hand, was the only known experimental OTEC central system operating at the Natural Energy Laboratory of Hawaii. Ocean Thermal Energy Conversion has the opportunity to become one of the sources of energy. To reach their goal OTEC that financial support and research much more than its current state. The biggest obstacle that hinders the implementation of OTEC is the cost.Reduce costs to a reasonable level is not so simple because the method used to drive OTEC. Thermal energy of the oceans is considered safe for the environment. It also prevents the air pollutant. However, ocean thermal energy conversion should be set in contact with our current technology, because otherwise, OTEC plants have the ability to disrupt or even damage the local environment. There are three types of OTEC and OTEC cycle management, closed-loopOTEC and hybrid-cycle OTEC.
Economic Cycle OTEC uses a low-boiling liquid. An example of this is the liquid propane. Propane works as an intermediate fluid. The Ocean Thermal Energy Conversion system pushes the sea water temperatures in the reaction chamber, then boil the liquid interlayer. The result of the intermediate fluid vapor to drive the turbine engine power. After the steam is from the cold in cold seawater.
Open Cycle OTEC is almostapproached cycling. But in open loop, do not use liquid intermediate. Open-cycle OTEC uses sea water to drive the engine. Use a vacuum to moderate sea water in a low-pressure steam to be converted. The low pressure vapor is released in a particular area and create enough energy to power the turbine. To cool the steam and desalinated water, an additional deep ocean waters are cold, the steam was placed after you have created enough power.
FinallyThe hybrid-cycle OTEC but right now it's just speculation. Cycle hybrid approach is being investigated is that it is possible to use extreme heat from the ocean to illustrate. In fact, among the speculations of Hybrid Cycling There are two sub-theories. First, it is combined with the use of closed cycling for generating electricity. The energy produced is then used to create the necessary vacuum environment for cycling open. Secondly, a combination of two openCycling, it is twice the amount of desalinated water or created only in an open circuit.
In addition, as a source of electricity, has a closed loop system OTEC, the potential for the treatment of chemicals. On the other hand, OTEC plants can be cycling open and close to the wheel to drive the cold deep sea water, which are then used for refrigeration and air conditioning systems. In addition, when the system is closed by sea water, the environment can also be used for mariculture andDevelopment of aquaculture, as fish farming. In fact, there are a number of finished products and services that can be developed from this alternative energy source.
