Thermal energy storage is an effective technology to solve these problems, which can be mainly divided into three types: sensible heat storage, latent heat storage and thermochemical energy storage. Sensible heat is stored through the temperature difference of storage medium, which is simple but faces problems like low thermal storage density …
