The Storage Potential of CO2 in Various Geological Formations

The storage potential of CO2 in geological formations refers to how much carbon dioxide can be safely stored underground. Potential formations include depleted oil and gas fields, deep saline aquifers, and unmineable coal seams. These layers are porous rocks that can hold CO2 like a sponge, while being capped by non-porous rocks that prevent leakage. The capacity varies depending on the size, porosity, and seal integrity of each formation. Overall, many of these formations could store hundreds to thousands of years' worth of CO2 emissions, making them crucial for reducing greenhouse gases and combating climate change.
