Abstract. We optimize the design and time-varying operation of a CO 2-capture-enabled power station burning coal and natural gas, subject to a CO 2 emission intensity constraint. The facility consists of a coal-fired power plant and an amine CO 2 capture system, which is powered by a combined-heat-and-power auxiliary gas-fired subsystem. The detailed design of the CO 2 capture system, the ...
