Carbon Capture Utilization and Storage (CCUS) is considered an important technology that can abate and reduce the anthropogenic effects of CO2. The technology consists mainly in capturing the CO2 from high-intensity emissions sources and transporting it either to be utilized again as raw material or to be stored permanently in an adequate formation. The storing formations can be aquifers, oil and gas reservoirs, and coal mines. However, due to the abundant presence of aquifers, they are considered the main storage option for CO2. Once injected, the CO2 is trapped by a combination of several trapping mechanisms: the CO2 can be trapped structurally under the cap rock, residually due to the capillary forces acting on the plume, or it can be trapped in the aqueous or ionic phase due to its solubility in brine, which can eventually lead to the mineralization of the CO2.
