Partnership to build world's largest OTEC plant off China coast  

Posted by Big Gav in ,

PhysOrg has an article about a planned resort development powered by OTEC technology (a type of ocean energy) in China - Partnership to build world's largest OTEC plant off China coast.

Hong Kong based Reignwood Group and U.S. aerospace company Lockheed Martin have announced plans to build an Ocean Thermal Energy Conversion (OTEC) electricity generating plant off the coast of China to power a planned resort community. Lockheed Martin is to build the facility and run it, while the Reignwood Group will be building the resort community that is to use the power generated. The new plant is expected to produce 100 percent of the power needs of the community.

OTEC plants generate electricity by taking advantage of the difference in water temperature at different ocean depths—warm surface water is used to boil a fluid (one that has a low boiling temperature such as ammonia) that in turn drives a turbine. Cold water brought up from below cools the liquid causing it to once again liquefy allowing the process to repeat over and over. To date, few such plants have been built due to the large expense involved in transporting cold water up from below. The new plant to be built off the coast of southern China will be a pilot project designed to not only supply electricity to the new resort community, but also to serve as a learning environment, helping lead the way to more efficient, and hopefully cheaper plant designs.
