Solar thermal storage (STS) refers to the accumulation of energy collected by a given solar field for its later use. In the context of this chapter, STS technologies are installed to provide the solar plant with partial or full dispatchability, so that the plant output does not depend strictly in time on the input, i.e., the solar irradiation.
Reviewed different types of solar thermal energy storage (sensible heat, latent heat, and thermochemical storage) for low- (40–120 °C) and medium-to-high temperature (120–1000 °C) applications.
In order to solve the problem of the time-space mismatch of solar energy and further increase the solar fraction, solar-driven short-term low temperature (<150 °C) heat storage (SSLTHS) systems have received extensive attention.
Packed bed storage system is one of the feasible techniques to store the solar thermal energy which can be assembled with various solar thermal applications of low temperature as well as high temperature. The present review covers the sensible heat based packed bed solar thermal energy storage systems for low temperature applications.
Solar thermal energy is usually stored in the form of heated water, also termed as sensible heat. The efficiency of solar thermal energy mainly depends upon the efficiency of storage technology due to the: (1) unpredictable characteristics and (2) time dependent properties, of the exposure of solar radiations.
If we want to reduce our dependence on fossil fuels and also to mitigate greenhouse gas emissions, the roles of solar thermal energy storage systems are critical. In industrial and domestic applications, various types of solar thermal storage are used.
