Density of pure CO2 as a function of increasing depth

Density of pure CO2 as a function of increasing depth
Density ("Dichte") of pure CO2 changing with depth ("Tiefe") (in pink) – at a depth of about 800 m CO2 density is high enough to enable efficient CO2 storage (green-couloured area), while at shallow depths CO2 density is too low (red-coloured area).
