How can CO2 injected underground stay securely stored there?
Structural trapping is one of the natural trapping processes that ensures injected CO2 stays securely underground and will not leak to the surface or into ground water. Injected fluid CO2 tends to rise via buoyancy through the storage formation until it reaches a natural impediment such as one of the impermeable layers of caprock. This is known as structural trapping.

The microscopic pore spaces shown in the animation have been magnified many hundreds of times and normally would be invisible to the human eye. The animation above represents a space smaller than a millimeter (or less than 1/16 of an inch).
