Abstract

L'invention concerne des systèmes et procédés servant à retirer l'énergie thermique de moteur thermique de centrale électrique, à stocker puis à récupérer l'énergie stockée. L'énergie thermique retirée ou stockée permet d'élever l'enthalpie de sources de chaleur de température inférieure pour une utilisation dans les centrales génératrices de puissance électrique. L'invention concerne aussi des systèmes et procédés servant à intégrer et à installer en cascade un stockage d'énergie thermique multi-étage pour alimenter plusieurs utilisateurs de chaleur à des températures différentes. Les procédés s'appliquent aux centrales électriques utilisant l'énergie thermique à partir de collecteurs d'énergie thermique solaire concentrés, de réchauffeurs chauffés au combustible ou d'unités de récupération de chaleur de générateurs à turbine à gaz. Plusieurs modes de réalisation utilisent l'énergie stockée pour étendre le fonctionnement des centrales électriques thermiques solaires, en particulier dans l'impulsion motrice inférieure. D'autres modes de réalisation extraient l'énergie thermique d'une centrale électrique thermique solaire, stockant une partie de l'énergie extraite et récupérant cette énergie thermique pour chauffer en continu des fluides géothermiques utilisés dans une centrale électrique géothermique, et chauffer les fluides de travail de la centrale électrique géothermique.
