1. A method of sequestering carbon in a target zone of a subterranean formation, the method comprising:
compressing a mixed component gas comprising a carbon dioxide gas and at least a second gas;
mixing the compressed mixed component gas with pressurized liquid;
dissolving at least a portion of the carbon dioxide gas into the pressurized liquid, creating a carbonated liquid;
separating at least some of the second gas from the carbonated liquid, the separated second gas at a pressure above atmospheric pressure;
flowing the separated second gas to a pressure recovery system;
using the separated second gas to pressurize a mixed component gas for mixing with pressurized water; and
injecting the carbonated liquid into a subterranean target zone.
