Analysis of a thermoelectric generator (TEG) in an ocean thermal energy conversion (OTEC) application is presented. An analytic model is developed for describing the heat exchanger-TEG interactions. This model is used to illustrate limitations of applying conventional fixed junction temperature assumptions to systems experiencing significant temperature drops across the heat exchanger surfaces....

Ocean Thermal Energy Conversion (OTEC) is a promising renewable energy technology that the most economical at large scale. But contemporary literature does not address how OTEC could reach such scale with current technology, and what techno-economic impact of location-dependent factors technological learning are. This paper tackles these issues by simulating OTEC's upscaling model implements to...

Many Caribbean island nations have historically been heavily dependent on imported fossil fuels for both power and transportation, while at the same time being an enhanced risk from impacts of climate change, although their emissions represent a very tiny fraction global total responsible change. Small developing states (SIDSs) are among leaders in advocating ambitious 1.5 °C Paris Agreement ta...

The article proposes to using Ocean Thermal Energy Conversion (OTEC) increase the energy efficiency mining of methane from deposits subaquatic gas hydrates on hydrate cycle (GHET), that will allow not spend 10-15% extracted for power supply a gas-producing complex (GPC). circuit-technological solution GPC is described, according which carbon dioxide introduced into layer extract hydrates. To im...

Ocean Thermal Energy Conversion is an important renewable energy technology aimed at harvesting the large resources connected to temperature gradient between shallow and deep ocean waters, mainly in tropical region. After first small-size demonstrators, current focused on use of Organic Rankine Cycles, which are suitable for operating with very low temperatures resource. With respect other appl...
