The problem of energy storage is especially actual in respect to renewable sources of energy, such as sun, wind, tides, which have seasonal or diurnal variations and which therefore are not available at any moment of time. This article overviews the main principles of storage of solar energy for its subsequent long-term consumption.
Thermal energy storage (TES) refers to a collection of technologies that store excessive energy in thermal forms (hot and/or cold) and use the stored thermal energy either directly or indirectly through energy conversion processes when needed.
