An ocean thermal energy conversion power plant built by Makai Ocean Engineering went operational in Hawaii in August 2015. The governor of Hawaii, David Ige, "flipped the switch" to activate the plant. This is the first true closed-cycle ocean Thermal Energy Conversion (OTEC) plant to be connected to a U.S. electrical grid.
The Ocean Thermal Energy Conversion Act of 1980 (OTECA) is an act authorized by Congress to address ocean thermal conversion. It is one of six acts enacted by the Energy Security Act of 1980. [1] Ocean thermal energy conversion is the extraction of energy from the thermal differentials of subsea and surface water in regions with tropical oceans ...
Ocean heat content (OHC) or ocean heat uptake (OHU) is the energy absorbed and stored by oceans. To calculate the ocean heat content, it is necessary to measure ocean temperature at many different locations and depths. Integrating the areal density of a change in enthalpic energy over an ocean basin or entire ocean gives the total ocean heat ...
A thermocline (also known as the thermal layer or the metalimnion in lakes) is a distinct layer based on temperature within a large body of fluid (e.g. water, as in an ocean or lake; or air, e.g. an atmosphere) with a high gradient of distinct temperature differences associated with depth.
Marine energy, also known as ocean energy, ocean power, or marine and hydrokinetic energy, refers to energy harnessed from waves, tides, salinity gradients, and temperature differences in the ocean. The movement of water in the world's oceans stores vast amounts of kinetic energy , which can be converted into electricity to power homes ...
The original mission was for research into the uses of deep ocean water in ocean thermal energy conversion (OTEC) renewable energy production and in aquaculture. It later added research into sustainable uses of natural energy sources such as solar energy. Its administration offices are located in the HOST Park Keahole Point in the North Kona ...
Graph showing ocean temperature versus depth on the vertical axis. The graph shows several thermoclines (or thermal layers) based on seasons and latitude. The temperature at zero depth is the sea surface temperature. The ocean temperature plays a crucial role in the global climate system, ocean currents and for marine habitats.
William Hinckley Avery (July 25, 1912 – June 26, 2004) was an influential aeronautical engineer.He designed the propulsion mechanism known as the ramjet, and was known for heading the Ocean Thermal Energy Conversion program which generates electricity from the temperature differential between shallow and deep ocean water.
