Carbon capture and storage (CCS) is the separation and capture of carbon dioxide (CO2) from the emissions of industrial processes prior to release into the atmosphere and storage of the CO2 in deep underground geologic formations.
Carbon dioxide (CO2) can be stored underground as a supercritical fluid. Supercritical CO2 means that the CO2 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 CO2. At such high temperatures and pressures, the CO2 has some properties like a gas and some properties like a liquid. In particular, it is dense like a liquid but has viscosity like a gas. The main advantage of storing CO2 in the supercritical condition is that the required storage volume is substantially less than if the CO2 were at “standard” (room)-pressure conditions.
Trapping refers to the way in which the carbon dioxide (CO2) remains underground in the location where it is injected. There are four main mechanisms that trap the injected CO2 in the subsurface. Each of these mechanisms plays a role in how the CO2 remains trapped in the subsurface. The following provides a description of each type of trapping mechanism.
