Abstract
A gas turbine system is configured to inhibit release of carbon dioxide to the atmosphere in such a manner that methane is combusted with oxygen that has been separated from air by an oxygen generator to allow an oxygen combustion type gas turbine to be driven. Carbon dioxide emitted from the turbine is fed under pressure into an underground coal bed along with an air component after separating the oxygen from the air and fixed into the coal bed, and the coal bed methane is collected above the ground by a gas drive action of the gas and supplied to the gas turbine as fuel.
