Thermal power does not need energy storage why does new energy require 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 is a sensible heat thermal energy storage material?

A sensible heat thermal energy storage material is one that stores heat energy in its specific heat capacity (C p). The thermal energy stored by sensible heat can be expressed as Q = m · C p · ΔT, where m is the mass, C p is the specific heat capacity, and ΔT is the raise in temperature during charging process.

What are thermal energy storage materials for chemical heat storage?

Chemical heat storage systems use reversible reactions which involve absorption and release of heat for thermal energy storage. These systems typically operate within a middle range temperature between 200 °C and 400 °C.

How can Thermal Energy Storage (TES) reduce costs?

Continued research effort is needed to reduce cost through the use of alternative cheap TES materials from renewable biosources, naturally occurring earth materials, industrial waste materials, etc.

How TES is compared with battery based electricity storage technology?

When the source energy form to be stored is low grade thermal energy, TES has round–trip efficiency in the range 50%–100%.

What are the different types of thermal energy storage?

Thermal energy storage can be classified according to the heat storage mechanism in sensible heat storage, latent heat storage, and thermochemical heat storage. For the different storage mechanisms, Fig. 1 shows the working temperature and the relation between energy density and maturity.
