Abstract
A method and apparatus for sequestering carbon dioxide (CO) gas and releasing natural gas from underground coal and/or gas shale formations using COgas captured from the flue gas of a coal burning power plant, and processing it to produce cold liquid pressurized CO, and injecting the cold liquid COunder pressure to create fractures within the formation and causing the COto be adsorbed into the coal or gas shale and natural gas (CH) to be desorbed, released and recovered. A special pressure cycling process is used to enable the pressure within the formation to be increased and decreased, including allowing the liquid COto change phase to a gaseous CO, and injecting the liquid COunder pressure repeatedly, which causes greater expansion of the proliferation zone within the formation, and more efficiently releases CH.
