Houben, J. (author), Sögütoglu, L.C. (author), Donkers, P. (author), Huinink, H. (author), Adan, O.C.G. (author)Potassium carbonate, K2CO3, has been identified as one of the most promising thermochemical storagematerials for the built environment. Where a lot of knowledge has been gained on hydration/dehydrationbehavior at atmospheric (open system) conditions, little is known of this process under pure water vaporconditions (closed vacuum system). In this...article 2020

Sogütoglu, L.C. (author), Steiger, M. (author), Houben, J. (author), Biemans, D. (author), Fischer, H.R. (author), Donkers, P.A.J. (author), Huinink, H. (author), Adan, O.C.G. (author)The solid-state hydration of salts has gained particular interest within the frame of thermochemical energy storage. In this work, the water vapor pressure-temperature (p-T) phase diagram of the following thermochemical salts was constructed by combining equilibrium and nonequilibrium hydration experiments: CuCl 2 , K 2 CO 3 , MgCl 2 ·4H 2 O,...article 2019

Sögütoglu, L.C. (author), Donkers, P.A.J. (author), Fischer, H.R. (author), Huinink, H.P. (author), Adan, O.C.G. (author)Thermochemical materials K2CO3, MgCl2 and Na2S have been investigated in depth on energy density, power output and chemical stability in view of domestic heat storage application, presenting a critical assessment of potential chemical side reactions in an open and closed reactor concept. These materials were selected based on a recent review on...article 2018

Donkers, P.A.J. (author), Sögütoglu, L.C. (author), Huinink, H.P. (author), Fischer, H.R. (author), Adan, O.C.G. (author)A literature review is performed in order to collect and analyse the thermodynamic data of an utmost number of salt hydrate reactions (i.e., 563 reactions are reviewed). These data allow us to evaluate the theoretical possibilities and limitations of salt hydrates as thermochemical materials (TCMs) for seasonal heat storage in the built...article 2017
