HYSTORE project aims at developing different thermal energy storage solutions that would not only serve as a means for improving the energy efficiency of the buildings where they will be installed, but also as an asset to the electric grid. One of the solutions for storing heat for a period of up to 4 weeks is the use of a thermochemical energy storage. The goal of this report is to present the selection of the material to be used within the thermochemical HYSTORE solution. To this aim, a decision process based on a weighted scoring system was used, which takes into account both technical and economic constraints. The methodology consists of 5 steps: 1. Literature Review 2. Criteria Selection 3. Weighting of Criteria 4. Scoring System 5. Evaluation and Ranking Out of this process, the zeolite 13X produced in Italy by UOP was selected and a characterization campaign was carried out. This consisted of both thermo-physical characterization (adsorption capacity, specific heat) and thermo-electrical characterization (i.e. measurement on the impedance of the material and drying time under RF heating). The latter, takes into account the operating conditions of HYSTORE, which consist of charging using radio-frequency. Finally, the discharging behaviour was addressed by means of a validated model developed in COMSOL Multiphysics.

Abstract
HYSTORE project aims at developing different thermal energy storage solutions that would not only serve as a means for improving the energy efficiency of the buildings where they will be installed, but also as an asset to the electric grid. One of the solutions for storing heat for a period of up to 4 weeks is the use of a thermochemical energy storage. The goal of this report is to present the selection of the material to be used within the thermochemical HYSTORE solution. To this aim, a decision process based on a weighted scoring system was used, which takes into account both technical and economic constraints. The methodology consists of 5 steps: 1. Literature Review 2. Criteria Selection 3. Weighting of Criteria 4. Scoring System 5. Evaluation and Ranking Out of this process, the zeolite 13X produced in Italy by UOP was selected and a characterization campaign was carried out. This consisted of both thermo-physical characterization (adsorption capacity, specific heat) and thermo-electrical characterization (i.e. measurement on the impedance of the material and drying time under RF heating). The latter, takes into account the operating conditions of HYSTORE, which consist of charging using radio-frequency. Finally, the discharging behaviour was addressed by means of a validated model developed in COMSOL Multiphysics.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
