What is thermal energy storage and heat transfer media?
What are Thermal Energy Storage and Heat Transfer Media? Thermal energy storage (TES) refers to heat that is stored for later use—either to generate electricity on demand or for use in industrial processes.
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.

How does thermal energy storage work?
Thermal energy storage can be obtained by cooling, heating, melting, solidifying, or vaporizing a material in which the energy becomes available as heat by reversing the process. Using this method provides the opportunity to mitigate environmental impacts and results in more efficient and clean energy systems.
What are some sources of thermal energy for storage?
Other sources of thermal energy for storage include heat or cold produced with heat pumps from off-peak, lower cost electric power, a practice called peak shaving; heat from combined heat and power (CHP) power plants; heat produced by renewable electrical energy that exceeds grid demand and waste heat from industrial processes.
How does heat transfer occur?
Heat transfer occurs when thermal energy moves from one place to another. Atoms and molecules inherently have kinetic and thermal energy, so all matter participates in heat transfer. There are three main types of heat transfer, plus other processes that move energy from high temperature to low temperature. What Is Heat Transfer?
