Thermal energy storage (TES) systems can store heat or cold to be used later, at different conditions such as temperature, place, or power. TES systems are divided in three types: sensible heat, latent heat, and sorption and chemical energy storage (also known as thermochemical).
Thermal energy is stored solely through a change of temperature of the storage medium. The capacity of a storage system is defi ned by the specifi c heat capacity and the mass of the medium used. Latent heat storage is accomplished by using phase change materials (PCMs) as storage media.

Definition: The energy storage capacity of the system (ESCsys) calculates the total amount of heat that can be absorbed during charging under nominal conditions. The energy is mainly stored in the material; however, some set-ups may contain components in contact with the material, which inevitably heat up, hence storing sensible heat.
In most cases, storage is based on a solid/liquid phase change with energy densities on the order of 100 kWh/m3 (e.g. ice). Thermo-chemical storage (TCS) systems can reach storage capacities of up to 250 kWh/t, with operation temperatures of more than 300°C and efficiencies from 75% to nearly 100%.
The storage material energy storage capacity (ESCmat) is calculated according to the type of TES technology: i. ESCmat for sensible = heat · TES . . Eq. 4 cp.mat: Specific heat of the material [J·kg-1·K-1]. Mmaterial: mass of the storage material [kg]. ∆Tsys: Design temperature difference of the system [K].
in energy need to be balanced. One of the main functions of energy storage, to match the supply and demand of energy (called time shifting), is essential for large and small-scale applications. In the following, we show two cases classifi ed by their size: kWh class and MWh class.
