On The Potential For Co2 Mineral Storage In Continental Floodbasalts—phreeqc Batch And 1d Diffusion-reaction Simulations

Underground sequestration of carbon dioxide is a potentially viable greenhouse gas mitigation option as it reduces the release rate of CO2 to the atmosphere [1]. CO2 can be trapped subsurface by four storage mechanisms: (1) structural and stratigraphic trapping; (2) residual CO2 trapping; (3) solubility trapping; and (4) mineral trapping [2]. Mineral trapping has been considered as the safest mechanism in long-term storage of CO2[3].
