For example, if the aim of the thermal energy storage is to store solar energy, charging period will be the daytime for daily storage and the summer for seasonal storage. The solar energy is converted to the heat in solar collectors and charged into a storage medium like water, rock bed, phase change material, etc.
Component level – This level of design pertains to the selection of the basic components that are used for forming the thermal energy storage system, including storage material, type of contact and heat transfer between the storage material and the HTF, and any heat transfer enhancements to be incorporated. 3.
Active two-tank systems The principal elements for a two-tank thermal energy storage system are the material inventory, HTF, heat exchangers and the storage tanks, apart from the storage material circulation pumps. During charging, the amount of heat stored in the fluid depends on the heat supplied by the solar field.
The thermal storage system in the above references was a two-tank system designed to deliver thermal energy at full-rated duty of the steam generator for three hours at the defined hot and cold salt temperatures of 565 °C and 288 °C, respectively.
The operational principles of thermal energy storage systems are identical as other forms of energy storage methods, as mentioned earlier. A typical thermal energy storage system consists of three sequential processes: charging, storing, and discharging periods.
Depending on the storage material chosen, any configuration must be able to store the required amount of energy within the duration of application and should be economical. In terms of thermal performance, it is critical that the storage system has high energy density and has adequate charging and discharging rate capability.
