In This Section  | NewsNREL UPDATE OF HYDROGEN BUSES AT AC TRANSIT
The National Renewable Energy Laboratory (NREL) has recently published a report on its evaluation of fuel cell buses in service at AC Transit in Oakland, California. This report provides an update to the previous report (Mar 2007) and includes results and experience through Aug 2007. The evaluation covers three fuel cell buses in comparison to new diesel baseline buses operating from the same bus depot.
The 40-ft Van Hool fuel cell bus features an electric hybrid drive system by ISE Corporation with UTC Power's PureMotion 120 Fuel Cell Power System and ZEBRA batteries for energy storage. During the data collection period (Apr 2006 - Aug 2007), the fuel cell buses achieved more than 54,000 miles in service with an overall fuel economy of 6.17 miles per kg which equates to 6.97 miles per diesel equivalent gallon. For comparison, AC Transit's diesel buses have an average fuel economy of 4.03 miles per gallon.
