Thermochemical Storage: First Results of Pilot Storage System with Moist Air
Abstract
The laboratory of Thermal systems at CEA-INES works on seasonal storage of solar thermal energy for household applications. Thermochemical storage has been adopted and hydration/dehydration reactions of inorganic salts are being used. The objective of this work is to evaluate the feasibility of a significant scale thermochemical storage system operating under conditions as close as possible to reality. Complete hydration/dehydration cycles have been performed using moist air both as reactive and heat transfer vector. The present paper presents the experimental setup, an energy analysis, theoretical assumptions on thermochemical storage and the first results of storage.
