Carbon Storage FAQs | netl.doe.gov

Carbon dioxide (CO 2) can be stored underground as a supercritical fluid. Supercritical CO 2 means that the CO 2 is at a temperature in excess of 31.1°C (88ºF) and a pressure in excess of 72.9 atm (about 1,057 psi); this temperature and pressure defines the critical point for CO 2.
