Molten salts are used in solar power tower systems because they are liquid at atmospheric pressure, provide an efficient, low cost medium in which to store thermal energy, their operating temperatures are compatible with today''s high-pressure and high-temperature steam turbines, and they are non-flammable and non-toxic.
Applications like house space heating require low temperature TES below 50 °C, while applications like electrical power generation require high temperature TES systems above 175 °C [2].The performances of the TES systems depend on the properties of the thermal energy storage materials chosen.
The importance of high temperature thermal energy storage needs hardly any emphasis. The intermittent nature of sun''s energy, importance to the central receiver solar thermal power system programs, and growing needs of energy in industries have necessiated the development of high temperature thermal storage systems.
Molten salts (MSs) thermal energy storage (TES) enables dispatchable solar energy in concentrated solar power (CSP) solar tower plants. CSP plants with TES can store excess thermal energy during periods of high solar radiation and release it when sunlight is unavailable, such as during cloudy periods or at night.

Thermochemical energy storage (TCES) systems stand out from conventional thermal storage technologies because of their ability to channel solar energy using reversible gas–solid reactions. TCES relies on powder technology. As powders react absorbing the solar energy, byproducts can readily be stored in different silos.
CaL conditions for CSP storage involve calcination of CaCO 3 in the solar receiver at relatively low temperature whereas carbonation of CaO is carried out at high temperature and high CO 2 concentration to use the heat of reaction for power production by means of a CO 2 closed power cycle. Under these conditions, large CaO particles derived

Of all components, thermal storage is a key component. However, it is also one of the less developed. Only a few plants in the world have tested high temperature thermal energy storage systems. In this context, high temperature is considered when storage is performed between 120 and 600 °C.
The chemical storage technology is also promising, but is even less developed than the latent heat one for concentrated solar power heat storage. Some studies have claimed that ammonia and the SnO x /Sn reactions may be the most suitable ones, but much more investigation is still needed. 9.
Here a novel scheme of storing high temperature solar thermal energy into a shallow depth artificial reservoir (SDAR) is proposed.
Thermal energy storage (TES) systems have the potential of increasing the effective use of thermal energy equipment and of facilitating large-scale switching.
