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.
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.
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.
Marcelo A. Barone Solar thermal storage (STS) refers to the accumulation of energy collected by a given solar field for its later use.
But Zalba et al. and Sharma et al. reported that the thermal storage subsystems including the solar collector, most have a high thermal storage density, excellent heat transfer rate, low construction cost and long-term durability.
This would reduce the cost of thermal storage by requiring just the expense of drilling holes for injecting and withdrawing water. If water is utilized for higher temperature applications (temperatures over 100 °C), it must be pressured, which increases the expense; in this instance, the critical point, 374 °C, is the limit of water .
