Deep Ocean Water Application Research Center (DOWARC) of the Maritime and Ocean Engineering Research Institute (MOERI) and Korea Institute of Ocean Science and Technology (KIOST) have completed to install a 20kW OTEC pilot plant in October 2013 and are going to have a public demonstration in November 2013 after trial run and basic performance test.
DOWARC, MOERI has been working on a national project called ‘Development of utilization technology of deep… Continue reading
With the increasing number of OTEC projects around the globe, more and more industrial companies increase their focus and product range towards OTEC. An example for this is the recent product update by Kobe Steel, Ltd and its announcement to provide high heat transfer titanium sheet specifically designed for OTEC plants.
Kobe Steel, Ltd. has developed a high heat transfer titanium sheet called HEET™ for use in plate heat exchangers, one of the important applications… Continue reading
Looking at the latest developments in the OTEC world, much has been going on with regard to research and testing, but also policy developments in Europe and Northern America. Yet with the latest announcement of Lockheed Martin and Reignwood Group to install a 10 MW power plant in China, more and more attention is payed to South East Asia with a great potential for OTEC.
OTEC will also be addressed at the upcoming Offshore Renewable… Continue reading
Okinawa Prefecture has announced the start of the OTEC operation test at Kume Island on April 15th. The main aim is to examine the expected fluctuation of electricity supply caused by changes in weather, season, and sea temperature. The testing and research will be conducted with the support of Saga University until the end of 2014.
IHI Plant Construction Co. Ltd, Yokogawa Electric Corporation, and Xenesys Inc were entrusted to construct the 50 kilowatt plant… Continue reading
Today, Lockheed Martin has announced that it is working with Reignwood Group to develop an Ocean Thermal Energy Conversion (OTEC) pilot power plant off the coast of southern China. A memorandum of agreement between the two companies was signed in Beijing on Saturday. Following the ceremony, both companies met with United States Secretary of State John Kerry during his first official state visit to the People’s Republic of China.
The 10-megawatt offshore plant, to be… Continue reading
Various attempts have been made in the past to estimate the global ocean thermal energy potential with also a significant span in ranges. The last IPCC reports states a recoverable OTEC potential of 108-324 EJ per year while the IIASA ended up with a value of 30,000 EJ per year [Avery, W. H., and G. L. Dugger. "Contribution of ocean thermal energy conversion to world energy needs." International Journal of Ambient Energy 1.3 (1980): 177-190.].… Continue reading
Ocean Thermal Energy Conversion (OTEC) uses large flows of warm surface seawater and cold deep seawater to generate clean electricity. The tropical ocean at a typical OTEC site has two distinct layers: a warm surface layer with low nutrient levels, and a cold deep layer that is nutrient-rich. Introducing deep nutrients into the ocean’s sun-lit upper layers could potentially increase plankton growth or cause algal blooms. Thus, seawater discharged from an OTEC plant should be… Continue reading
