This report is the sixth in a series of annual status reports from the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory (NREL).It summarizes status and progress from demonstrations of fuel cell transit buses in the United States. Since 2000, NREL has evaluated fuel cell electric bus (FCEB) demonstrations at transit agencies, including the buses, infrastructure, and each transit agency’s implementation experience. These evaluations were funded by both DOE and the U.S. Department of Transportation’s (DOT) Federal Transit Administration (FTA). This work is described in a joint evaluation plan.

This annual status report discusses the achievements and challenges of fuel cell propulsion for transit and summarizes the introduction of fuel cell transit buses in the United States. It provides an analysis of the combined results from fuel cell transit bus demonstrations evaluated by NREL with a focus on the most recent data (through July 2012).
