Solar thermal plant is one of the most interesting applications of solar energy for power generation. The plant is composed mainly of a solar collector field and a power conversion system to convert thermal energy into electricity.
Solar thermal power plants benefit from free solar energy for clean electricity production with low operational cost and greenhouse gases emissions. However, the major hurdle for developing these plants is the intermittence of solar energy leading to a mismatch of energy production with the energy demand.
Thermal energy storage provides a workable solution to this challenge. In a concentrating solar power (CSP) system, the sun's rays are reflected onto a receiver, which creates heat that is used to generate electricity that can be used immediately or stored for later use.
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.
A solar thermal plant can utilise the infrared and a small part of the visible spectrum. This energy is absorbed and used to raise the temperature of a heat transfer fluid. However, most of the visible light energy is rejected in a solar thermal plant.
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.
