The world’s largest sand battery has started working in the southern Finnish town of Pornainen. Capable of storing 100 MWh of ...

A combination of thermal conversion and carbon capture is commercially ready and can offset some of the emissions from the process, but a new report from the U.S. Department of Energy (DOE ...

Known as ocean thermal energy conversion or ‘OTEC,’ the technology was first invented in 1881 by French physicist Jacques Arsene d’Arsonval. He discovered that the temperature difference ...

Called ocean thermal energy conversion (OTEC), the idea is to use surface water warmed by the sun to heat a fluid such as ammonia or water, which then spins a turbine as it evaporates, just like a ...

These energy conversions are done with thermodynamic cycles, the same physical principles used to run refrigerators, car engines or thermal power plants. The storage tanks can be filled with ...

Hawaii became the first state in the US to generate electricity from the thermal energy stored in ocean water using a new 105-kilowatt ocean thermal energy conversion (OTEC) plant on Big Island ...

A small but operational ocean thermal energy conversion (OTEC) plant was inaugurated in Hawaii last week, making it the first in the world. The opening of the 100-kilowatt facility marked the ...

An Ocean Thermal Energy Conversion (OTEC) pilot plant off the coast of Hawaii’s Big Island is now a step closer to reality. The U.S. Naval Facilities Engineering Command (NFEC) has just awarded ...

One project, Ocean Thermal Energy Conversion, or OTEC, leverages the temperature difference between surface water and deeper ocean troughs in tropical and sub-tropical oceans. Though the ...

Ocean thermal energy conversion, or OTEC, taps into this energy to produce electricity. Ocean thermal energy conversion relies on the fact that water near the surface is heated by sunlight while ...
