Abstract[English]
Systems and methods for coproduction of hydrogen gas and a metal are provided. Systems include at least one injection well 102, at least one production well 104 in fluid communication with the at least one injection well 102, a source of an aqueous based solution 101 in fluid communication with the at least one injection well 102, an iron containing source rock formation 110 containing an additional metal, and a collection tank 105, fluidly connected to the at least one production well 104. Methods include identifying an iron containing source rock formation 110 including iron and an additional metal, heating an aqueous based solution 101 to a reaction temperature, injecting the heated aqueous based solution 101 into the iron containing source rock formation 110, reacting the iron containing source rock formation 110 and the heated aqueous based solution 101 in a water-rock reaction to produce a post-reaction fluid 123 including hydrogen and the additional metal, and producing the post-reaction fluid 123 with a production well 104.[French]
L'invention concerne des systèmes et des procédés de coproduction d'hydrogène gazeux et d'un métal. Les systèmes comprennent au moins un puits d'injection 102, au moins un puits de production 104 en communication fluidique avec le ou les puits d'injection 102, une source d'une solution aqueuse 101 en communication fluidique avec le ou les puits d'injection 102, une formation rocheuse source contenant du fer 110 contenant un métal supplémentaire, et un réservoir de collecte 105, en communication fluidique avec le ou les puits de production 104. Les procédés comprennent l'identification d'une formation rocheuse source contenant du fer 110 comprenant du fer et un métal supplémentaire, le chauffage d'une solution aqueuse 101 à une température de réaction, l'injection de la solution aqueuse chauffée 101 dans la formation rocheuse source contenant du fer 110, la réaction de la formation rocheuse source contenant du fer 110 et de la solution aqueuse chauffée 101 dans une réaction eau-roche pour produire un fluide de post-réaction 123 comprenant de l'hydrogène et le métal supplémentaire, et la production du fluide de post-réaction 123 avec un puits de production 104.
