dc.description.abstractThe continuously increasing CO2 concentration in the atmosphere has been a major global concern over the past few decades. Subsurface CO2 storage in various geological media has been proven to be one of the large-scale options to mitigate emissions, and provide a secure way to sequester CO2 for long time periods. The sequestration of CO2 in the subsurface depends on different trapping mechanisms which must be carefully evaluated in order to ensure safe storage and accurate predictions of storage potential. One of these trapping mechanisms, mineralization, has been shown to be one of the most secure over geologic time scales. Mineralization of CO2 is directly dependent on the interaction between CO2, in-situ brine, and the rock. In this study, we use reactive transport modeling to study the CO2-water-rock interactions and also investigate the mineralization potential of CO2 in reactive volcanic rocks such as basalts.
