Heat batteries quietly solve a major transition gap, storing surplus renewable electricity as heat.

The Finnish start-up says its sand battery technology is scalable from 20 to 500 MWh with charging power from 1 to 20 MW, depending on industrial needs.

These nanosheets operate using a dual-mode heat storage mechanism, where water molecules are simultaneously absorbed (intercalated) and adsorbed from the atmosphere. (Nanowerk News) Efficiently ...

Engineered “biochar” made from waste wood and natural clay minerals could help buildings stay comfortable while cutting ...

Texas has nearly 7.5GW of storage capacity in operation, which Solargis suggested is a key reason for the resilience of the state’s electricity grids. Image: SB Energy. Fluctuations in solar power ...

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 ...

As global energy demand accelerates, one truth remains underappreciated: heat is the largest end use of energy. Today, more than 50 percent of global final energy consumption is dedicated to ...

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 ...

A worker loads a portable thermal battery onto a truck. The battery is charged using the waste heat from a biofuel plant and transported to an apartment block, where it provides heating for water.

Lithium-ion batteries dominate headlines, but most global energy storage relies on simpler methods. These methods include pumped hydro, compressed air, gravity, and thermal storage using sand or rock.
