In This Section  | NewsPRELIMINARY EVALUATION OF HYDROGEN BUSES IN SUNLINE TRANSIT, USAThe National Renewable Laboratory (NREL) has recently published a preliminary report on its evaluation of hydrogen and fuel cell buses in service at SunLine Transit Agency in Thousand Palms, California. The report includes 11 months of performance data on two hydrogen fueled buses: one fuel cell bus and one hybrid hydrogen fueled internal combustion engine bus (HHICE). Data on 5 new CNG buses are provided as a baseline.
The 40-ft Van Hool fuel cell bus features an electric hybrid drive system by ISE Corporation with UTC Power's PureMotionTM 120 Fuel Cell Power System and ZEBRA batteries for energy storage.
The HHICE bus from New Flyer has essentially the same electric hybrid drive system from ISE Corp., but with ultracapacitors for energy storage and a Ford V10 Triton engine customized to operate on hydrogen fuel.
The report also outlines the overall experience for the transit agency and it's project partners in demonstrating these buses. The report can be dowloaded here.
