19. A method of enhancing rates of in situ carbonation of peridotite, said method comprising:
-
fracturing a volume of peridotite in situ, said volume of peridotite being located beneath a volume of fluid, said volume of fluid having a top surface and said volume of fluid including dissolved carbon dioxide; heating a first amount of said volume of fluid adjacent said top surface and adjacent said volume of peridotite; after heating, injecting said first amount into said volume of peridotite; and forming carbonate in situ with a first amount of said volume of peridotite and said dissolved carbon dioxide in said first amount of said volume of fluid, wherein forming carbonate in situ generates a heat source. - View Dependent Claims (20, 21)
