As part of the USDOE's Carbon Sequestration Program, an integrated modeling framework was developed to evaluate the performance and cost of alternative carbon capture and storage (CCS) technologies for fossil-fueled power plants in the context of multi-pollutant control requirements. The model (called IECM, for Integrated Environmental Control Model) also allows for explicit characterization of the uncertainty or variability in any or all input parameters. Power plant options currently include pulverized coal (PC) combustion plants, natural gas combined cycle (NGCC) plants, and integrated gasification combined cycle (IGCC) plants. This paper uses the IECM to analyze the effects of adding CCS to an IGCC system employing a GE quench gasifier with a water gas shift reactor and Selexol system for CO2 capture. Parameters of interest include the effects of varying the CO2 removal efficiency, the quality and cost of coal, and selected other factors affecting overall plant performance and cost. The stochastic simulation capability of the model also is used to illustrate the effect of uncertainties or variability in key parameters. The potential for advanced oxygen production and gas turbine technologies to reduce the cost and environmental impacts of IGCC with CCS also is analyzed.
