Scientists in Spain have simulated a system that uses both power-to-heat-to-power thermal batteries and lithium-ion batteries for energy storage. The hybrid system reportedly achieved a 7% lower LCOE ...

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 ...

Heat is a valuable resource, regardless of the season, and researchers at Kaunas University of Technology (KTU) have found that the soil under our feet can serve as an efficient thermal energy storage ...

Researchers have developed a heat storage unit that takes up less space than a regular hot water tank. It charges when electricity is cheap and releases heat when needed. Subscribe to our newsletter ...

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 ...

As renewable energy expands worldwide, one challenge remains stubbornly unresolved: how to store heat efficiently and sustainably when the sun is not shining or demand fluctuates. A new study shows ...
