Selecting Geological Formations for CO2 Storage: A Comparative Rating System

Underground storage of carbon dioxide (CO2) in geological formations plays a vital role capture and (CCS) technology. It involves capturing CO2 emissions from industrial processes power generation storing them underground, thereby reducing greenhouse gas curbing the impact climate change. This review paper features comparative analysis deep saline aquifers, depleted reservoirs, coal seams, basaltic clastic formations. The comparison has been drawn based upon seven factors carefully selected literature, i.e., safety, capacity, injection rates, efficiency, residual trapping, containment integrity potential to improve, all these have rated low (1) high (5) their individual traits. Based factors, an overall M.H. rating system developed categorize for it is observed that water aquifers are most effective options storage. Lastly, detailed way forward suggested, which can help researchers policymakers find more viable ways enhance efficiency various
