What is thermal energy storage?

Author to whom correspondence should be addressed. Thermal energy storage (TES) is a technology that stocks thermal energy by heating or cooling a storage medium so that the stored energy can be used at a later time for heating and cooling applications and power generation. TES systems are used particularly in buildings and in industrial processes.

Are thermal energy storage systems insulated?

Conclusions Today, thermal energy storage systems are typically insulated using conventional materials such as mineral wools due to their reliability, ease of installation, and low cost. The main drawback of these materials is their relatively high thermal conductivity, which results in a large insulation thickness.

What is thermal insulation?

Thermal insulation is aspect in the optimization of thermal energy storage (TES) systems integrated inside buildings. Properties, characteristics, and reference costs are presented for insulation materials suitable for TES up to 90 °C.

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.

Can thermal energy be stored in a heat storage media?

Thermal energy (i.e. heat and cold) can be stored as sensible heat in heat stor-age media, as latent heat associated with phase change materials (PCMs) or as thermo-chemical energy associated with chemical reactions (i.e. thermo-chemical storage) at operation temperatures ranging from -40°C to above 400°C.

What is sensible heat storage?

Sensible heat storage is relatively inexpensive compared to PCM and TCS systems, and is applicable to domestic systems, district heating and industrial needs. However, sensible heat storage requires in general large volumes because of its low energy density, which is 3 and 5 times lower than that of PCM and TCS systems, respectively.
