6 FAQs about [The economics 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 is a thermal energy storage system?

By heating (or cooling) a storage medium, thermal energy storage systems (TES) store heat (or cold). As a result, further energy supply is not required, and the overall energy efficiency is increased. In most cases, the stored heat is a by-product or waste heat from an industrial process, or a primary source of renewable heat from the sun.

Why are thermal energy storage systems still in the development phase?
