Sandip S. Deshmukh, in Journal of Energy Storage, 2022 Sensible heat storage is the process of storing energy by increasing the temperature of a medium having a high heat capacity, such as water or rock [66,67]. Sensible heat storage materials can be classified into two main types, as shown in Fig. 8. Fig. 8.
The amount of stored heat is proportional to the density, specific heat, volume, and temperature variation of the storage materials. Basically, specific heat, density and thermal conductivity are the main thermal properties of sensible heat storage materials. Fig. 1 shows the main thermal properties of sensible heat materials.

Among the existing TES class, latent heat storage (LHS) is quite good as compared to a sensible heat storage system (SHS) due to its high energy storage density (Sari and Karaipekli 2007).The phase change process of LHS permits 5–14 times additional thermal energy per unit volume to be stored with the SHS material (Lamberg 2004; Sharma et al. 2009).
It is a relatively straightforward process for sensible heat storage, given the dependence of enthalpy on temperature for the bulk of accumulation media, such as water, is well understood.
