Abstract:
Deep saline aquifers have greater potential for carbon dioxide (CO2) storage (around 12,000 Gt global capacity)
than alternative storage media and could be adopted anywhere in the world. It is important to understand
methodologies for the estimation of CO2 storage capacities in relation to different trapping mechanisms and the
extent to which critical parameters such as aquifer thickness, porosity, salinity and permeability are taken into
account. Storage security will improve over time, especially as a result of mineral trapping. This paper reviews
methods of estimating CO2 storage potential from earlier studies and numerically estimates the storage potential
in saline aquifers considering critical parameters such as saline aquifer and porosity.
