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.
The solar thermal storage unit can also improve the equipment performance in terms of a smooth supply of energy with fluctuated solar energy collection as solar radiation varies throughout a day.
2. The properties of solar thermal energy storage materials 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 .
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.
Seasonal solar thermal storage system store energy during the hot summer months and use it during colder winter weather. Solar thermal energy is captured by solar collectors and stored in different ways. The three above mentioned parameters used to calculate the TES potential are described with the following equations:
The performances of solar thermal energy storage systems A TES system consists of three parts: storage medium, heat exchanger and storage tank. Storage medium can be sensible, latent heat or thermochemical storage material . The purpose of the heat exchanger is to supply or extract heat from the storage medium.
