Optimization of the Coating Process of a Ca(OH)2‐Based Thermochemical Energy Storage Material

“…In latent heat storages (LHS), which are also known as phase change materials (PCM), the storage medium undergoes a phase transition as melting and solidification within a specific temperature range during charging and discharging [4,5]. The major amount of heat is stored within this phase change during which the temperature of the storage medium does not change [7]. The storage density of LHS materials is related to their specific heat of fusion and storage periods are limited by the efficiency of thermal insulation.…”

“…A big advantage of TCES is, that the energy can be stored cold and loss free within a nearly unlimited storage period 5, 6, 8. This characteristic allows a local decoupling of charging and discharging 7. Examples for common TCES materials are zeolites or silica gel (physisorption and desorption of water) as well as hydroxides, hydrates and carbonates (chemisorption and desorption of H 2 O or CO 2 ) 4.…”
