The OTEC association, standing for the conversion of ocean thermal energy, was founded by French engineer called Jacques D'Arsonval back in 1881. The only remaining plant that is still a member of the OTEC is based in Hawaii and represented a natural energy laboratory. OTEC represents a source that can produce alternative energy which is currently, however, underrated and unexploited.
The thing that stands in the way of the popularization of the OTEC is that it costs too much at this point for many to afford it. It is thus difficult, to keep costs down to some level because processes affected the OTEC, rendering inefficient. Thermal energy derived from the ocean needs to be cleansed and treated of any remains and then it can be utilized in the air. It is also fairly important that the water coming from the oceans is not polluted, since otherwise, you would risk to fail completely in the transformation. Therefore, one needs to pay careful attention when utilizing the OTEC at any point.
To begin with, you should know that there are three types of OTEC.
The first one is Closed Cycle OTEC which uses a liquid with low boiling points; one such liquid is propane which is an intermediate fluid. OTEC plants pump water which is warm into reaction chambers which boil the water and use the intermediate fluid you have already chosen. This means that the vapor pushes the turbine into the engine and generates electricity. As a consequence, the vapor is cooled and then is used into cold water coming from the sea.
The second types is the Open Cycle OTEC, which does not differ from the closed method to a large extent. In here, you use no intermediate fluid and you use the sea water to drive the engine across. In this format, the sea water that is located on the surface ocean becomes transformed in low pressure vapors, under the action of a vacuum. Then, the vapor that was produced, which is , keep in mind, low pressure, is released in another container and it thus located in that it is capable to power the turbine. Then, you need to cool the vapor and also, to produce water with no remnants of salt from the ocean in it. After you do that, the water coming from the deeper parts of the ocean will be added to vapors, and then it becomes capable to generate electricity.
The last technique is called "Hybrid Cycle", but this technique is for the moment, not implemented. It describes an optimal approach you could use thermal energy at the maximum from the waters of the ocean. There exist two theories concerning the hybrid cycling. As a consequence, the first means using the closed cycling operation to generate electricity. Thus, the amount of electricity is then used to establish the cleaning environment that you will need for open cycling. Therefore, the electricity that you produce this way will be used to integrate the open cycling together. You then produce double the amount of water that was desalinated.
Besides the fact of using OTEC to produce electricity, the plant with OTEC has a closed cycle, which can be utilized to treat chemicals. The OTEC plants, are capable of pumping cold water coming from the sea and then use it for further purposes : refrigeration or air conditioning. While under moderation in which the sea water surrounds the plant, what you obtain from the process can be reused in aquaculture crops, for instance in fish farming.
If you know how to exploit the opportunities you have, you will find that there are numerous uses to the services and the products derived from this alternative to energy production.
