In the passive type TES systems, thermal storage material is fixed and it does not flow, which is in contrast to the active system. The thermal storage material is used only to store thermal energy which can be transferred to and from the heat transfer fluid via thermal charging and discharging. A passive-type thermal storage system can be a solid material (example: concrete), fluid (example: water) or phase change material (example: PCM). In such systems, the heat transfer fluid transfer energy to the thermal storage material where the material stores energy which can be further transferred to the heat transfer fluid. Such systems have not been integrated in solar thermal power plants till date. The works on passive thermal energy storage system are on the laboratory and fundamental level. A good number of research works can be found in literature on the passive thermal energy storage system.
