Abstract

StoRRe proposal concerns the area of thermal energy storage by chemical reaction for concentrated solar power plants (CSP). The objective of the project is to develop a new and promising solution for the heat storage with the following characteristics: a) Mid-term (24h to few days) up to long-term (several months) heat storage b) High storage density (300-500 kWh∙m3), c) High temperatures (300-550°C), which are representative of the CSP plants with cylinder-parabolic or CLFR technologies. The objective of the StoRRe project is to develop and quantify, at a pilot scale, the interest of a thermochemical storage solution with the dehydration of Ca(OH)2, and to study the development opportunity at the pre-industrial scale. The consortium is composed of a major industrial manufacturer involved in the CSP business, a SME developping innovative solar and biomass technologies and three research centres.
