Abstract

Un système de stockage/conversion d'énergie géothermique utilise de l'eau chaude et une pression, telle que de la vapeur, générée par la chaleur géothermique/l'eau souterraine pour stocker de l'énergie et/ou générer de l'électricité. Le système utilise un mouvement d'un piston, entraîné par la vapeur générée par la chaleur géothermique, pour commander le mouvement d'une quantité d'eau, qui est utilisée pour stocker l'énergie par compression de gaz en tant que stockage d'énergie. Lorsque de l'électricité est nécessaire, le gaz comprimé fournit une force pour pousser l'eau stockée afin d'entraîner un hydrogénérateur pour générer de l'électricité. Dans un mode de réalisation de conversion d'énergie géothermique, le système utilise un mouvement d'un piston, entraîné par la vapeur générée par la chaleur géothermique, pour commander le mouvement d'une quantité d'eau afin d'entraîner un hydrogénérateur pour générer de l'électricité.
