Thermal energy storage provides a workable solution to the reduced or curtailed production when sun sets or is blocked by clouds (as in PV systems). The solar energy can be stored for hours or even days and the heat exchanged before being used to generate electricity .
Solar tower thermal power generation technology, which is also referred to as central receiver technology, uses a large number of heliostats having a dual axis control system (one about the elevation axis and the other about the azimuthal axis). These heliostats reflect direct beam solar radiation to a receiver located at the top of a tower.
Solar tower thermal power generation system is composed of three parts, which are the concentrating heat system, the thermal storage system and the power block. Concentrating heat system is made up of concentrating subsystem and absorber subsystem.
The first three units of Solnova in the foreground, with the two towers of the PS10 and PS20 solar power stations in the background. Solar thermal energy (STE) is a form of energy and a technology for harnessing solar energy to generate thermal energy for use in industry, and in the residential and commercial sectors.
Solar energy has a one-day period, meaning that the ‘long term’ storage requirements is based on hours. In that context, thermal energy storage technology has become an essential part of CSP systems, as it can be seen in Fig. 13, and has been highlighted over this review.
However, one of the key factors that determine the development of this technology is the integration of efficient and cost effective thermal energy storage (TES) systems, so as to overcome CSP's intermittent character and to be more economically competitive. This paper presents a review on thermal energy storage systems installed in CSP plants.
