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),
PCMs play a decisive role in the process and efficiency of energy storage. An ideal PCM should be featured by high latent heat and thermal conductivity, a suitable phase change temperature, cyclic stability, etc. [33] As the field now stands, PCMs can be classified into organic, inorganic, and eutectic types shown in Fig. 1.

By integrating phase change energy storage, specifically a box-type heat bank, the system effectively addresses load imbalance issues by aligning building thermoelectric demand with system output. This approach increases energy storage density, improves space utilization efficiency, and streamlines maintenance.
Energy intensity measures the amount of energy consumed per unit of gross domestic product. It effectively measures how efficiently a country uses energy to produce a given amount of economic output. A lower energy intensity means it needs less energy per unit of GDP. This interactive chart shows energy intensity.

LHESS uses phase change materials (PCMs) as energy storage mediums: energy is stored during melting and released during solidification. Various applications are found in the open literature including space heating and cooling [2], [3], solar domestic hot water systems [4], incorporating PCMs into building elements [5], [6]
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] .
