Abstract

The methods disclosed herein relate to sequestering carbon dioxide in an aquifer by trapping the CO2 in interstitial pores of the aquifer. Trapping the CO2 in the interstitial pores of the aquifer prevents the sequestered CO2 from escaping back to the surface and allows a much larger percentage of a CO2 to be stably sequestered compared to techniques that rely on dissolving the CO2 to achieve stable sequestration.
