The world's largest ocean temperature difference power plant is made in China

Lockheed MartinCompanyRainwood GroupIn cooperation with China, the world's largestOcean temperature difference power generation (OTEC)Announced the construction of the plant. According to the plan, the power plant will be 10 MW in scale and this plant will supply energy to Hainan Island resort facilities developed by the Rainwood Group. Ocean temperature difference power generation has not yet reached the construction of a large-scale facility, but the possibility that OTEC's commercialization is realized by this has increased.

OTEC technology developed by Lockheed MartinYou can see the overview from the following movie.

Ocean Thermal Energy Conversion - YouTube


Ocean Temperature Differential Power Generation (OTEC) utilizes the difference in water temperature between the deep sea and the surface layer in the tropical zone up to latitudes of 20 degrees to drive the heat engine to generate electricity. The ocean is constantly heated by the sun, whereas the deep water is relatively cool, and this temperature difference has been enormous as solar energy has been developed since the late nineteenth century.


OTEC is an island- or coastal-oriented technology that is expensive when using existing energy resources, unlike other renewable energy technologiesBase operation, 24 hours a day, 365 days a year can be produced continuously. 100 MW OTEC can generate the same amount of energy as 1.3 million barrel of oil-fired thermal power generation, so if commercial scale OTEC were to be made it would be possible to cover all the power of a small city I will.


Despite the fact that OTEC is not a new technology, one of the reasons that large facilities are not present at the present time is that costs are required to build facilities at remote locations from the coast and maintain it . It is also said that it costs a lot of money to pump water for cooling from the deep ocean.

However, while the Rainwood Group is progressing on projects related to green energy, we are developing a low-carbon resort in China, and by using Lockheed Martin's OTEC technology, energy consumption is practically zero It will be the first time in the world to make a success example of the "net-zero energy" community to become


The facility will be like this.


Lockheed Martin says to build OTEC facilities in Hawaii in the pastplanThere was also, but the plan has flowed. In the facility, we first used working fluid (water) with warm seawaterHeat exchanger (evaporator)Steam, turn the turbine with steam to generate electricity. Steam after finishing work used cold seawater this timeCondenserIt is sent back to the water. This water is sent to the evaporator again by the pump ... It is the cycle of .......


The agreement between the two companies is the largest in OTEC facilities ever, and we intend to construct more than 10 - 100 MW facility in addition to China. It is expected that about 3,500 people will be hired at one OTEC facility, and the plan will progress over the next ten years.
