Methods and systems for causing reaction driven cracking in subsurface rock formations are disclosed. In some embodiments, the methods include the following: drilling one or more holes in a substantially porous subsurface rock formation, the one or more holes in fluid communication with pores in the subsurface rock formation; injecting in the pores via at least one of the holes one or more fluids, wherein the one or more fluids include a gas; and chemically reacting the one or more fluids within the pores thereby causing cracking in the substantially porous subsurface rock formation.

Methods and systems for enhancing rates of carbonation of peridotite both in situ and ex situ are disclosed. In some embodiments, the methods and systems include the following: fracturing a volume of peridotite; heating the volume of peridotite; injecting an adjustable flow of carbon dioxide into the volume of peridotite; injecting bicarbonate materials into the volume of peridotite; and forming carbonate with the volume of peridotite and the carbon dioxide in an exothermic reaction thereby generating a self-sustaining heat source, the heat source heating the volume of peridotite.
