A system is provided for separating carbon dioxide emitted in exhaust gas from nitrogen gas. A compressor may be used for compressing the emitted exhaust gas and a heat exchanger may be used for cooling the compressed exhaust gas to liquid carbon dioxide temperatures. The liquid carbon dioxide may be separated from the compressed nitrogen gas and stored. A turbine may use the compressed nitrogen gas to drive the compressor, while further cooling the compressed nitrogen to cryo-temperatures. Heat exchangers may be used for transferring heat energy from emitted exhaust and the compressed exhaust to the cold compressed nitrogen, thus, conserving energy of the system.
