Abstract
A method for the subterranean regeneration of CO-philic solvents and the sequestration of carbon dioxide may include exposing the CO-philic solvent to a carbon dioxide-containing gas in an absorber to allow the CO-philic solvent to absorb at least a portion of the carbon dioxide in the carbon dioxide-containing gas, thereby producing a CO-containing solution. The CO-containing solution may be supplied to one or more porous rock fractures via one or more injection conduits in fluid communication with the one or more porous rock fractures. The CO-containing solution may be heated via heat provided by one or more rock fractures in order to release at least a portion of the absorbed carbon dioxide into the one or more rock fractures and thereby regenerate the CO-philic solvent. At least a portion of the released carbon dioxide may be sequestered by adsorbing the carbon dioxide within the porous rock fractures or by reacting the released carbon dioxide with the porous rock fractures to form stable carbonates. The regenerated CO-philic solvent may be transported from the one or more porous rock fractures via one or more production conduits.
