Phase change materials (PCMs), a key component of LHS systems, store and release thermal energy through their phase transitions. Paraffin, a widely used organic PCM, is a promising candidate for thermal energy storage because of its high latent heat, good thermal stability, and negligible supercooling ( Zhao et al., 2020 ).
It restricts the application potential of energy storage systems due to the higher heat conductivity and density of typical PCMs and their low phase change rates. Thus, increased thermal conductivity can be achieved by adding highly conductive materials in various methods [225] .

1. Introduction. Phase change materials (PCMs) have attracted tremendous attention in the field of thermal energy storage owing to the large energy storage density when going through the isothermal phase transition process, and the functional PCMs have been deeply explored for the applications of solar/electro-thermal …
Among the many energy storage technology options, thermal energy storage (TES) is very promising as more than 90% of the world''s primary energy generation is consumed or wasted as heat. 2 TES entails storing energy as either sensible heat through heating of a suitable material, as latent heat in a phase change material (PCM), …
Solar energy is a renewable energy source that can be utilized for different applications in today''s world. The effective use of solar energy requires a storage medium that can facilitate the storage of excess energy, and then supply this stored energy when it is needed. An effective method of storing thermal energy from solar is through the use of …

The solar energy was accumulated using 18 solar collectors made of thin gauge galvanised absorber plates, black painted and covered by double 1.2×3.0 m glazing panels. The heat generated from these panels was passed through a duct via a fan to three heat storage bins situated on either side of the rooms.
The energy storage characteristic of PCMs can also improve the contradiction between supply and demand of electricity, to enhance the stability of the power grid [9]. Traditionally, water-ice phase change is commonly used for cold energy storage, which has the advantage of high energy storage density and low price [10].
A few points to note about this data: Renewable energy here is the sum of hydropower, wind, solar, geothermal, modern biomass and wave and tidal energy. Traditional biomass – the burning of charcoal, crop waste, and other organic matter – is not included. This can be an important energy source in lower-income settings.

As shown in Figure 6, with the increase in heat storage temperature, the temperature hysteresis of phase change materials gradually decreases, and the phase change hysteresis degree declines. The phase change hysteresis decreases from 4.25 °C at 50 °C to 1.52 °C at. 80 °C.
A shape-stabilized phase change material (SSPCM) is composed of working substance and supporting material. The working substance stores or releases latent heat during the melting or solidifying processes, whereas the supporting material prevents the melted phase from leaking so the whole system remains in solid state [16].There is a …
