For PCM-based energy storage systems, latent heat is a crucial factor in determining the effectiveness of storage capabilities. The latent heat thermal energy is acquired by PCMs through the solid–liquid melting process as the binding forces that hold the solid structure are broken and eventually released during the liquid–solid

Thermal energy storage (TES) is a technology that reserves thermal energy by heating or cooling a storage medium and then uses the stored energy later for electricity generation using a heat engine cycle (Sarbu and Sebarchievici, 2018 ). It can shift the electrical loads, which indicates its ability to operate in demand-side management
CO2 mitigation potential. 1.1. Introduction. Thermal energy storage (TES) systems can store heat or cold to be used later, at different temperature, place, or power.
