What is thermochemical heat storage?
Thermochemical heat storage is a technology under development with potentially high-energy densities. The binding energy of a working pair, for example, a hydrating salt and water, is used for thermal energy storage in different variants (liquid/solid, open/closed) with strong technological links to adsorption and absorption chillers.
Why is thermal energy storage important?
For increasing the share of fluctuating renewable energy sources, thermal energy storages are undeniably important. Typical applications are heat and cold supply for buildings or in industries as well as in thermal power plants. Each application requires different storage temperatures.
