Abstract

An interesting thermochemical material for compact seasonal heat storage is magnesium sulfate heptahydrate MgSO4.7H2O. Previous studies in the field showed that this material presents a storage energy density of 1 GJ/m3 when the material is built in a TC storage system with a 50% porosity packed bed reactor. However, the material has slow reaction kinetics under the low vapor pressure typically occurring in a seasonal heat storage (13 mbar). The kinetic study presented in this paper shows that a higher water vapor pressure of 50 mbar increases the reaction kinetics of the dehydration process of MgSO4.7H2O, improving the performance of the material.
