This report presents the results of an updated Pathway Study for coal-based, integrated gasification fuel cell (IGFC) power systems with carbon capture and storage (CCS). The results quantify the performance and cost benefits for a series of projected gains made through the development of advanced technologies or improvements in plant operation and maintenance. The results represent the potential future benefits of IGFC technology development. They also provide DOE with a basis to select the most appropriate development path for IGFC, and to measure and prioritize the contribution of its R&D program to future power systems technology.
Performance and Cost of a Natural Gas Fuel Cell Plant with Complete Internal Reforming
The performance and cost of a natural gas fueled, fuel cell (NGFC) power system with complete internal reformation (IR) is presented in this report. The report presents an update to a previous NGFC Pathway Study that includes carbon capture and storage (2011). IR utilizes heat generated in the fuel cell stack directly for the endothermic reformation reaction, improving system efficiency. NGFC systems with complete IR form the ultimate embodiment of the current fuel cell technology development program at the National Energy Technology Laboratory, which is consistent with the commercialization strategies being pursued in the stationary power generation sector.

Contact: Katrina Krulla
NETL analyzed the strengths of the solid oxide fuel cell (SOFC) system in conjunction with distributed generation (DG) market segments in the U.S. and determined that natural gas compressor stations, grid strengthening, and data centers were potential early market-entry opportunities. These three DG market segments are projected to demand two gigawatts of additional power between now and 2018 and 25 GWs through 2040. This analysis showed that the DG SOFC system becomes cost competitive with other fossil-fuel based DG technologies after 25 MWe of installed capacity, around 2025. The SOFC DG application validates and enables utility scale fuel cell systems with carbon capture, and forms an essential first phase of the NETL technology development roadmap.

This document outlines the carbon capture goals set forth by DOE/NETL and provides a detailed breakdown and justification of their derivation.
QGESS: Process Modeling Design Parameters
The purpose of this section of the Quality Guidelines is to document the assumptions most commonly used in systems analysis studies and the basis for those assumptions. The large number of assumptions required for a thorough systems analysis make it impractical to document the entire set in each report. This document will serve as a comprehensive reference for these assumptions as well as their justification.
QGESS: Specifications for Selected Feedstocks
This document provides recommended specifications for various feedstocks that are commonly found in NETL-sponsored energy system studies. Adhering to these specifications should enhance the consistency of such studies. NETL recommends these guidelines be followed in the absence of any compelling market, project, or site-specific requirements in order to facilitate comparison of studies evaluating coal-based technologies.
Analysis of Natural Gas Fuel Cell Plant Configurations
Contact: Walter Shelton
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.

The IGFC plants in this study apply advanced, planar, solid oxide fuel cell (SOFC) technology with separate anode and cathode off-gas steams, and incorporate anode off-gas oxy-combustion for nearly complete carbon capture. The SOFC simulations utilize the expected operating conditions and performance capabilities of this solid oxide fuel cell technology, operating initially at atmospheric-pressure. The power plant cost and performance estimates reflect performance projections based on the current state of SOFC development, as well as projecting a pathway of SOFC technology development advances.

Current and Future Technologies for Gasification-Based Power Generation, Volume 2: Carbon Capture, Revision 1
Contact: Kristin J. Gerdes
The impact of a portfolio of advanced technologies in DOE's Clean Coal R&D Program were evaluated in gasification-based power plant configurations with carbon capture and sequestration (CCS) resulting in power plants that are significantly more efficient and affordable than today's fossil energy technologies. In the IGCC process, the study estimates that a 7 percentage point efficiency improvement over conventional gasification technology is possible. With fuel cell technology, process efficiency improvements of 24 percentage points are potentially achievable. Furthermore, successful R&D for the advanced technologies evaluated results in capital costs and cost of electricity that is more than 30% below that of conventional IGCC technology with CCS.

Contact: Chris Nichols
An analysis of the levelized cost of electricity (LCOE) from two integrated coal gasification fuel cell (IGFC) power plants that use solid oxide fuel cell (SOFC) technology to convert syngas to electricity. Results show that the fuel cell system is more expensive than a combustion turbine but that expense is counterbalanced by the decrease in the unit cost of upstream equipment due to the higher IGFC system efficiency. Furthermore, the fuel cell platform offers nearly 100% CO2 capture.
