Gaeini, M. (author), Rouws, A.L. (author), Salari, J.W.O. (author), Zondag, H.A. (author), Rindt, C.C.M. (author)Thermochemical heat storage in salt hydrates is a promising method to improve the solar fraction in the built environment. The major concern at this stage is liquefaction followed by washing out of active material and agglomeration into large chunks of salt, thus deteriorating the diffusive properties of the porous salt hydrate structure. In...article 2018
