Sensible (packed bed) heat storages
Sensible heat storages store heat by changing the temperature of a material or a mixture of materials. Beside simple (hot) water storages, usually used in domestic heating systems, liquids, gases but also solids are used as a storage medium. For packed bed heat storages, solids in the form of mineral and ceramic bulk material are used as heat storage medium. The direct contact with corrosive flue gases results in high efficiencies. The use of high-level temperature waste heat in industrial processes is a typical application, whereby the energy efficiency of factories can be increased. Just as the power and heat production of power plants can be decoupled.
