Fuel-Cell Power-System Configurations Utilizing Waste-Derived Fuels. Summary of Final Technical Report for the Period September 1977-August 1978

摘要

The objectives of this study are to recommend a technology development and demonstration program, achievable in the mid-1980's, for one or more fuel cell power system configurations which utilize fuels derived from wastes, and which when commercialized result in significant energy savings at the national level. To meet the objectives of the study, data on the sources, composition and quantities of wastes in the United States was compiled and energy potential determined. Various process alternatives of fuel-cell power systems utilizing waste derived fuels were developed. Various waste-gasification (liquid and gases) systems and fuel-cell systems were identified and an evaluation criteria developed. Initial screening of the systems was performed by applying these criteria to the identified systems. Conceptual designs were performed for the selected systems to determine the overall efficiencies, environmental impacts, and the electricity-production cost. The conceptual design led to the identification of technology gaps, process uncertainties, and the associated technical risks. Again applying the developed evaluation criteria to the designed systems, final selection of systems for demonstration was made. The size of the facilities for conceptual design was determined from economic viability and practicality points of view. However, the size of demonstration units was determined from the technical and economic scale-up points of view. The technological problems expected to be encountered are clearly defined. Technology development and demonstration program is developed, schedules made and funding requirements are estimated. (ERA citation 08:012525)
