The sensitivity analysis of the multi-functional energy system fueled by coal and natural gas with both production of hydrogen and power was performed, The impacts of the reforming process and the separation ratio of hydrogen on the system performance were investigated from points of view of cascading utilization of energy and integrated utilization of different fuels. And the variations of the system special parameters of the reforming process and the separation ratio of hydrogen were obtained. From the analysis, it is concluded that this multi-functional energy system makes the utilization of chemical energy more efficiently and simultaneously decreases the CO2 separation energy penalty. The advantages of this multi-functional energy system make it possible to separation CO2 with very low or even zero energy penalty compared with the reference systems.
