| Abstract | Hybrid solid oxide fuel cell-gas turbine (SOFC-GT) systems are among the most efficient and lowest emitting power generation systems conceived for use in locomotives. Their superiority was proven in stationary power applications with near-zero (natural gas operation) to zero (hydrogen operation) pollutant emissions. However, the feasibility and dynamic operation of these systems for use in locomotives has not been extensively investigated. In this report, a new system based on existing National Fuel Cell Research Center (NFCRC) control methods was developed by NFCRC at the University of California, Irvine (UCI) for these types of systems. These control strategies enable the hybrid SOFC-GT system for locomotive engines to follow dynamic power demands while keeping all of the components and system operating variables within acceptable limits of performance under fuel utilizations between 75 and 80 percent. A detailed economic analysis of potential SOFC-GT locomotive production and operation costs in comparison to other low pollutant emitting alternatives (e.g., diesel-electric, battery electric, catenary-electric) was accomplished. The economic analyses show that SOFC-GT systems are likely to cost more and lead to higher costs for delivering goods per ton-mile than the diesel-electric alternative which has higher emissions. SOFC-GT locomotives are likely to produce lower operating costs compared to the catenary-electric alternative, and significantly lower operating costs compared to the battery-electric alternative. |
