Thermal Energy Storage (TES) captures heat or cold across three fundamental mechanisms — sensible storage in materials such as water, rock, or molten salt; latent storage through phase transitions in PCMs; and thermochemical storage via reversible reactions in metal hydrides, zeolites, or calcium looping systems. Storage capacity, charge-discharge cycling efficiency, exergy retention, and thermal loss management define system performance across timescales ranging from diurnal buffering to interseasonal storage.
Integration contexts span concentrated solar power with molten salt two-tank configurations, district heating networks, industrial waste heat recovery, and absorption cooling. Packed bed regenerators, thermocline tanks, aquifer and borehole systems extend the design space further.
