An MIT spinout has been developing thermal batteries to efficiently store excess electricity from ...

The novel heat pump concept combines solar energy with chemical storage and reportedly consume 75% less electricity than conventional heat pumps. The system relies on a battery and a heat storage tank ...

An energy supplier in Finland has announced the upcoming construction of an underground seasonal thermal energy storage facility about the size of two Madison Square Gardens that could meet the ...

Heat batteries quietly solve a major transition gap, storing surplus renewable electricity as heat. Half of global energy demand is for heating, not power. They are simple, scalable, and far cheaper ...

Industrial heat consumes a huge proportion of global energy. Rondo Energy says its brick-toasting heat storage device is so cheap and efficient that it makes decarbonization an instant no-brainer ...

As Europe braces for a difficult winter, with energy prices still high and energy supplies at risk, the energy efficiency challenge feels more urgent than ever. One European company that has been ...

Researchers reviewed 110 studies on cold thermal energy storage in liquid-air energy storage, finding that cold storage performance has a far greater impact on system efficiency than previously ...

When spring arrives and the heating season comes to an end, keeping warm becomes less of an issue. However, scientists remind us that it is not just a seasonal necessity – heat is also a valuable ...

Salt batteries can store summer heat to be used in winter, but which salt works best for the purpose? On 19 December, Lian Blijlevens will defend her PhD thesis on her research into salt for heat ...
