volume requirements may be reduced by sequestration protocols involving extraction of brine,
dissolution of CO2 into the extracted brine at the surface, followed by reinjection of the CO2-saturated brine into the formation.5,18 To fully
evaluate this alternative operational paradigm for geologic CO2
storage requires comprehensive reservoir simulations that
consider pressure evolution, fluid flow, and temporal changes
in CO2 trapping mechanisms. In addition, associated process requirements including characterization of life cycle energy,
emissions, and economic implications must be considered.
