Is Geologic CO Storage Safe?
The geological formations that would be used to store CO 2 are porous rock (not open underground caverns), making massive releases extremely unlikely. In fact, because the CO 2 becomes trapped in the tiny pores of rocks, any leakage through the geological layers would be extremely slow, allowing plenty of time for it to be detected and dealt with.

Which area is the best for geologic carbon sequestration?
It is difficult to characterize one area as "the best" for carbon sequestration because the answer depends on the question: best for what? However, the area of the assessment with the most storage potential for carbon dioxide is the Coastal Plains region, which includes coastal basins from Texas to Georgia. That region accounts for 2,000 metric gigatons, or

Sealing efficiency analysis for shallow-layer caprocks in CO2
The CO 2 migrated from deeper to shallower layers may change its phase state from supercritical state to gaseous state (called phase transition). This phase transition makes both viscosity and density of CO 2 experience a sharp variation, which may induce the CO 2 further penetration into shallow layers. This is a critical and dangerous situation
