The number of OTEC related conferences is increasing, which confirms the recent gain in momentum for OTEC. We would like to highlight three upcoming conferences:
International OTEC symposium: 9 – 11 September 2013
In September the International OTEC symposium will be held as part of the 2013 Asia Pacific Clean Energy Summit and Expo. The symposium will provide a platform for information exchange and discussion, and will identify steps to OTEC commercialization for… Continue reading
Sarah Crawford, a Kona attorney and coffee farmer, has been selected as the new executive director of the Friends of NELHA. Crawford’s selection was announced by David Kaapu, chairman of the board of directors for Friends of NELHA.
Crawford is a graduate of Stanford University and the University of San Francisco School of Law. Her law practice has involved mediating disputes and counseling clients in the areas of technology and intellectual property licensing.
Prior to… 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
Thursday 17 January 2013, a seminar was given by Rémi Baillot in Paris, France about Georges Claude and his adventures as OTEC pioneer. The OTEC foundation attended the seminar and would like to share the unique material that was shown of Claude’s work.
Rémi Baillot reconstructed Georges Claude’s extraordinary journey filled with adventures, battles and conquests. Supported by numerous illustrations, he described the story of this fearless, brave, clever, but also imperious man in… 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
The OTEC foundation team was shocked and saddened to hear of the sudden passing of Guy Toyama, a renowned champion of renewable energy, a Blue Revolutionist, an accomplished entrepreneur, and Executive Director of the Friends of NELHA.
When we started building the OTEC foundation, Guy was the first to share with us that he loved our idea to start a collaborative initiative to raise global awareness for OTEC. A few months earlier he organized the… Continue reading
The conversion of ocean thermal energy into electricity (OTEC) relies on the availability of temperature differences of the order of 20°C in the upper water column. The area of interest covers about a third of all oceans. Intense solar radiation keeps the surface layer of most tropical seas warm, as large surface heat fluxes between the ocean and the atmosphere reach a subtle balance. The existence of a pool of deep cold seawater at low… Continue reading
