METHOD FOR COPRODUCTION OF METALS AND HYDROGEN FROM GEOLOGICAL ROCK FORMATIONS BY INJECTING AQUEOUS SOLUTION

원문 (중국어)

Systems and methods for coproduction of hydrogen gas and a metal are provided. Systems include at least one injection well, at least one production well in fluid communication with the at least one injection well, a source of an aqueous based solution in fluid communication with the at least one injection well, an iron containing source rock formation containing an additional metal, and a collection tank, fluidly connected to the at least one production well. Methods include identifying an iron containing source rock formation including iron and an additional metal, heating an aqueous based solution to a reaction temperature, injecting the heated aqueous based solution into the iron containing source rock formation, reacting the iron containing source rock formation and the heated aqueous based solution in a water-rock reaction to produce a post-reaction fluid including hydrogen and the additional metal, and producing the post-reaction fluid with a production well.
