A Study of the Hydration and Dehydration Transitions of Srcl2 Hydrates for Use in Heat Storage [PDF]
SSRN Electronic Journal, 2022 We have experimentally determined the main thermodynamic properties of SrCl2, a potentially promising salt for thermochemical heat storage. We found a high energy density of 2.4 ± 0.1 GJ/m3 and proved full cyclability for at least 10 cycles going from the anhydrate to the hexahydrate without chemical degradation.
