Selecting Geological Formations for CO2 Storage: A Comparative Rating System

Abstract: Underground storage of carbon dioxide (CO2) in geological formations plays a vital role in carbon capture and storage (CCS) technology. It involves capturing CO2 emissions from industrial processes and power generation and storing them underground, thereby reducing greenhouse gas emissions and curbing the impact of climate change. This review paper features a comparative analysis of CO2 storage in deep saline aquifers, depleted reservoirs, coal seams, basaltic formations and clastic formations. The comparison … Show more

“…The amount of pore space available for CO 2 to be stored is largely controlled by the porosity of the formation [31]. The base of the model shows the highly porous Lower Mount Simon Sandstone formation (Mount Simon A and B), which we identified as the target injection interval to utilize the large amount of pore space available for CO 2 storage.…”

“…Geological survey techniques play a crucial role in identifying and characterizing geological formations suitable for carbon storage, a key component of carbon sequestration strategies , Rasool, Ahmad & Ayoub, 2023. Carbon storage, also known as carbon capture and storage (CCS), involves capturing carbon dioxide (CO2) emissions from industrial processes and storing them underground to prevent their release into the atmosphere.…”

“…These reactive minerals, such as olivine, serpentine, or certain types of basalt, contain elements like magnesium, calcium, or iron, which readily react with CO 2 to form solid carbonate minerals [39]. The carbonation reaction involves the dissolution of CO 2 in water to form carbonic acid (H 2 CO 3 ), which then reacts with the mineral surface to release metal cations (e.g., Mg 2+ , Ca 2+ , Fe 2+ ) and form stable carbonate minerals (e.g., magnesium carbonate, calcium carbonate, iron carbonate) [40].…”
