This report provides an overview of the current status of electric drive technologies for transit applications, covering battery-electric, hybrid-electric and fuel cell buses. Based on input from the transit and electric drive industries, the analysis examines the state of electric drive technology for transit buses, including a list of current deployments; the benefits of major market penetration of electric drive buses to both transit and the broader community; the barriers that remain to achieving this goal; and potential steps the transit industry believes the Federal Transit Administration (FTA) could take to alleviate some of these barriers. The report focuses on hybrid-electric technology as the most commercially-viable technology for fullsize transit buses today. There is a review of technical aspects of hybrid systems; emissions and fuel economy results to date; capital and operating costs; reliability, performance and durability issues; and regulatory status. . |
