Performance of a micro gas turbine using exhaust gas recirculation for CO2 capture decreases due to the rise in compressor inlet temperature. In this work, we devised a novel micro gas turbine system combined with liquid air energy storage (LAES) to prevent the MGT performance reduction. LAES, one of energy storage systems, stores electricity in the form of cryogenic liquid air. The cryogenic air was injected into compressor inlet of the MGT to decrease the inlet temperature. The system configuration is proposed and the performance improvement of the MGT according to the injection air amount is presented in this paper.
