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.

About Hot energy storage medium

The different kinds of thermal energy storage can be divided into three separate categories: sensible heat, latent heat, and thermo-chemical heat storage. Each of these has different advantages and disadvantages that determine their applications. Sensible heat storage (SHS) is the most straightforward method. It simply means the temperature of some medium is either increased or decreased. This type of storage is the most commerciall. Storage media include water or ice-slush tanks, masses of native earth or bedrock accessed with heat exchangers by means of boreholes, deep aquifers contained between impermeable strata; shallow, lined pits filled with gravel and water and insulated at the top, as well as eutectic solutions and phase-change materials.
