Solar thermal energy storage is used in many applications: buildings, concentrating solar power plants and industrial processes. Solar thermal water heaters capable of heating water during the day and storing the heated water for evening use are common. TES improves system performance by smoothing supply and demand and temperature fluctuations.
Thermal energy storage for CSP plants. Sensible heat storage: defined as storage that exploits the physical properties of a material to store thermal energy at the expense of a temperature rise of the material itself, due to the temperature variation fluid used.
In solar thermal applications, the solar collector plays a crucial role in absorbing solar radiation and converting it into heat, which is then transferred to the working fluid [ 10, 11 ]. The thermal energy collected can be utilized directly for supplying hot water or for heating and cooling systems in buildings.
Thermal storage plays a crucial role in solar systems as it bridges the gap between resource availability and energy demand, thereby enhancing the economic viability of the system and ensuring energy continuity during periods of usage.
Seasonal storage is defined as the ability to store energy for days, weeks or months to compensate for a longer term supply disruption or seasonal variability on the supply and demand sides of the energy system (e.g., storing heat in the summer for use in the winter via underground thermal energy storage systems) [ 12 ].
After the receiver captures the heat on the HTF, the thermal energy is transported either for conversion or for storage. 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).
