Geologic Carbon Storage
"CO2 is stored through four trapping mechanisms. These mechanisms occur simultaneously on injection within the pore space of a storage reservoir; however, the importance of each trapping mechanism – physical, residual, dissolution, mineralisation – changes with time and with the CO2 plume's evolution. Trapping of CO2 is strongly dependent on a site’s geology and local formation conditions (fluids, pressure, temperature)."
