The main driving force for the sequestered carbon dioxide to escape from the injection point is the buoyancy in both concepts The striking difference in the CO2 behaviors between the cases of aquifer and ocean sequestration is the free water body availability, which explains well the timescale of CO2's returning to the atmosphere. For the leakage concerns, the carbon cycle consideration will give clues on the ocean sequestration case, while a possible self-sealing mechanism will play an important role in the risk assessment of the aquifer sequestration.
