Intégration d'un procédé de stockage thermochimique à une centrale solaire thermodynamique : de l'expérimentation à l'échelle matériau aux performances énergétiques à l'échelle système

Abstract : High-temperature heat storage processes using thermochemical solid/gas reaction exhibit great interest for applications in solar thermodynamic power plants. The reactive pair CaO/Ca(OH)2 is suitable for this recovery step application ranging from 350 to 550°C within steam pressures from 0.2 to 2 bar. Heat and mass transfer Ca(OH)2+GNE beds parameters were evaluated through correlations and experimentations. Experiments achieved recovery reaction powers above 200kW.m-3 for compatible durations with solar power plants (1 to 15 hours). A 2D model was developed, validated and exploited to study the coupled influences of different parameters on the performance of TCS. Finally, the benefit of different configurations of TCS integration within the solar power plant have been highlighted in terms of thermal performances and sources and sinks power exchanges.
