Geological sequestration involves injecting CO2 into deep underground geological formations. All three mentioned sites are considered potential locations for this process.<br \/>\nStatement 1 is correct. Abandoned and uneconomic coal seams have pore spaces within the coal matrix where CO2 can be stored. Injecting CO2 can displace adsorbed methane, potentially offering enhanced coal bed methane recovery while sequestering CO2.<br \/>\nStatement 2 is correct. Depleted oil and gas reservoirs are geological formations that previously held hydrocarbons for millions of years, indicating they are well-sealed and suitable for trapping fluids. They are prime candidates for CO2 injection for storage, often combined with Enhanced Oil Recovery (EOR) or Enhanced Gas Recovery (EGR) techniques.<br \/>\nStatement 3 is correct. Subterranean deep saline formations are porous rock layers saturated with highly saline water. These formations are vast and globally abundant, offering the largest potential storage capacity for CO2 compared to coal seams or depleted reservoirs.
