As the photovoltaic (PV) industry continues to evolve, advancements in Energy storage density and latent heat have become critical to optimizing the utilization of renewable energy sources. From innovative battery technologies to intelligent energy management systems, these solutions are transforming the way we store and distribute solar-generated electricity.
Latent heat thermal energy storage systems (LHTESS) are versatile due to their heat source at constant temperature and heat recovery with small temperature drop. In this context, latent heat thermal energy storage system employing phase change material (PCM) is the attractive one due to high-energy storage density with smaller temperature difference
Latent heat thermal energy storage (LHS) involves heating a material until it experiences a phase change, which can be from solid to liquid or from liquid to gas; when the material reaches its phase change temperature it absorbs a large amount of heat in order to carry out the transformation, known as the latent heat of fusion or vaporization depending on the
Latent heat thermal energy storage (LHETS) has been widely used in solar thermal utilization and waste heat recovery on account of advantages of high-energy storage density and stable temperature as heat charging and discharging.

7.3.2 Latent Heat Thermal Energy Storage. LHS materials are known as PCMs because of their property of releasing or absorbing energy with a change in physical state. The energy storage density increases and hence, the volume is reduced in the case of LHS. The main advantage of LHS over SHS is the high storage density within a small temperature
Latent heat thermal energy storage is an attractive technique as it can provide higher energy storage density than conventional heat energy storage systems and has the capability to store heat of fusion at a constant (or a near constant) temperature corresponding to the phase transition temperature of the phase change material (PCM).

Latent heat storage (LHS) is mainly divided into three types: solid-solid, solid-liquid, and liquid-vapor phase change. The essence of sensible heat storage is to trade energy density by sacrificing exergy. Therefore, the storage temperature and the load-side demand temperature are two influential design parameters. The storage temperature
