Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling applications and power generation. TES systems are used particularly in buildings and in industrial processes.
During the charging process of the heat storage system, solar energy is stored in the form of sensible heat, latent heat, and chemical energy through the calcination and melting of CaCO 3 /CaO-CaCl 2 solid solution and during the discharge process, CaCO 3 /CaO-CaCl 2 undergoes carbonation and solidification, releasing heat for power generation.
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.
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.
Sensible heat storage stores the thermal energy by varying the temperature of storage materials, without undergoing any form of phase change within the working temperature range. The amount of thermal energy stored or released is proportional to the density ρ ρ, volume V V, specific heat cp c p, and temperature variation of the storage materials:
According to Kuravi et al. , for a sustainable and practical solar thermal storage system design, considerations come first, followed by the selection of storage material, designing of components incorporating the storage material and the system consisting of storage tanks, heat exchangers and piping, respectively.
The simulation analyzes heat distribution and temperature changes from the heat storage system to the heating terminal. The results indicate that although the solar collectors operate for 26.3% of the total heat storage and heating period, the cumulative heat stored is 45.4% higher than the total heating load.
