- •
Salt hydrates thermochemical storages reject ⅔ of the charging heat at the condenser.
- •
A cascade thermochemical storage with internal condensation heat recovery is proposed.
- •
This cascade design improves the energy and exergy efficiencies.
- •
In the case study, energy and exergy efficiencies were enhanced by a factor of 1.8.
- •
The process with heat recovery requires less heat input during the charging.
