Modeling of a thermochemical heat storage system for buildings
In this context, this paper aims at modeling a thermochemical heat storage system for buildings. The moist air operating model was chosen as the most suitable mode for seasonal thermochemical storage, for a reactor containing a fixed bed of SrBr 2 (strontium bromide) of high density, as well as a thermochemical storage model: Sharp Front
Thermochemical Energy Storage for High-Temperature
The energy storage density of such thermochemical pathway is usually 5 to 10-fold higher in comparison with sensible and latent energy storage systems. TCES systems based on reversible solid-gas reactions thus appear to be the most promising candidates for long-term stable storage of solar energy.
Comparison of closed and open thermochemical processes,
In a closed thermochemical system, the salt reacts with pure water vapor at vacuum pressure, while in an open system, the reactive solid bed is crossed by a moist air flow at atmospheric

Experimental study of a thermochemical energy storage system
The thermochemical heat storage (TCES) process materials have the advantage of high storage density compared to other thermal storage materials [9]. The TCES principle is to use a reversible chemical reaction between species to store heat: the reaction is endothermic in one sense and exothermic in the other, A solid + heat ↔ B solid + C gas .
