||This report presents the results of a Pathway Study for natural gas fueled, fuel cell (NGFC) power systems with carbon capture and sequestration (CCS). The results quantify the performance and cost benefits for a series of projected gains made through the development of advances in the component technologies or improvements in plant operation and maintenance. The design and cost bases for this pathway study closely follows the bases applied in the NETL, 2010, Bituminous Baseline report so that direct performance and cost comparisons can be made with the conventional fossil-fuel power plant results estimated in that report. Performance and cost projections for a baseline integrated gasification combined cycle (IGCC) power plant, a baseline natural gas combined cycle (NGCC) power plant, and prior coal-based integrated gasification fuel cell (IGFC) pathways, are compared with the results for the NGFC pathways. The results represent the potential future benefits of NGFC technology development. They also provide DOE with a basis to select the most appropriate development path for NGFC, and to measure and prioritize the contribution of its R&D program to future power systems technology.
