Demonstration of Fuel Cells to Recover Energy from Anaerobic Digester Gas. Phase1. A Conceptual Design, Preliminary Cost, and Evaluation Study

摘要

The report discusses Phase I (a conceptual design, preliminary cost, andevaluation study) of a program to demonstrate the recovery of energy from waste methane produced by anaerobic digestion of waste water treatment sludge. The fuel cell is being used for this application because it is potentially one of the cleanest energy technologies available. The program is focused on utilizing a commercial Phosphoric Acid Fuel Cell (PAFC) power plant because of its inherently high fuel efficiency, low emissions characteristics, and high state of development. The environmental impact of widespread use of this concept would be a significant reduction in global warming and acid rain air emissions.
