Application scenarios of thermal energy storage

Why is thermal energy storage important?

Thermal energy storage (TES) is increasingly important due to the demand-supply challenge caused by the intermittency of renewable energy and waste heat dissipation to the environment. This paper discusses the fundamentals and novel applications of TES materials and identifies appropriate TES materials for particular applications.

What are the application scenarios for energy storage systems?

There is an extensive range of application scenarios for industrial and commercial energy storage systems, including industrial parks, data centers, communication base stations, government buildings, shopping malls and hospitals.

What are the different types of thermal energy storage systems?

Thermal energy storage (TES) systems store heat or cold for later use and are classified into sensible heat storage, latent heat storage, and thermochemical heat storage. Sensible heat storage systems raise the temperature of a material to store heat. Latent heat storage systems use PCMs to store heat through melting or solidifying.

What are the applications of thermochemical energy storage?

Numerous researchers published reviews and research studies on particular applications, including thermochemical energy storage for high temperature source and power generation [, , , ], battery thermal management , textiles [31, 32], food, buildings [, , , ], heating systems and solar power plants .

How is thermal energy storage classified?

Considering the application (residential, industrial, and thermal power generation) and temperature characters of heat storage materials (evaporating point, melting point, decomposing temperature, etc.), thermal energy storage can also be classified according to the temperature range. The criteria of the temperature range are non-uniform.

Which two technologies are used in heat storage?

We classify the two technologies as one method (TCES) in this paper. There are many chemical reaction materials used in heat storage, such as metal hydrides, metal hydroxides, metallic carbonates, metal oxides, etc. . The comparison of energy density of different energy storage mechanisms is shown in Fig. 1 [23, 25].
