Title
(EN) SYSTEM FOR GEOTHERMAL PRODUCTION OF ELECTRICITY
(FR) SYSTEME GEOTHERMIQUE DE PRODUCTION D'ELECTRICITE
Abstract
(EN)
A system (10) for the generation of electricity from geothermal energy relies on using endothermic reactions at the bottom of a well (12) to capture and store geothermal heat, and exothermic reactions at the top of the well (12) to release the heat stored within the products of the endothermic reactions. In one preferred embodiment, the endothermic reaction is the decomposition of water. To induce the endothermic reaction as well as to harvest and separate the resulting products, a catalytic device (22) is used where each type of product selectively diffuses into its individual conduit (24, 26). The endothermic products undergo the exothermic reaction in a combustion tubine (240), and the products of the exothermic reaction are immediately condensed in a condenser (242). In one preferred embodiment, the condenser (242) condenses steam into liquid water to be returned down the well (12), thus creating a closed system.

Ce système (10) de production d'électricité à partir de l'énergie géothermique repose sur l'utilisation de réactions endothermiques au fond d'un puits (12) pour capter et stocker la chaleur géothermique, ainsi que sur des réactions exothermiques au sommet de ce puits (12) pour libérer la chaleur stockée dans les produits des réactions endothermiques. Selon un mode de réalisation préféré, la décomposition de l'eau constitue la réaction endothermique. Pour induire cette réaction endothermique et récupérer et séparer les produits résultants, on utilise un dispositif catalytique (22) dans lequel chaque type de produit diffuse sélectivement dans sa propre conduite (24, 26). Les produits endothermiques subissent la réaction exothermique dans une turbine à combustion (240), et les produits de cette réaction exothermique sont immédiatement condensés dans un condenseur (242). Selon un mode de réalisation préféré, ce condenseur (242) condense la vapeur en eau, laquelle est renvoyée vers le bas du puits (12), ce qui crée un système fermé.
