Hydrogen Fuel Cell Transit Bus Demonstration Project

Fuel cells offer near-zero emissions and significant reductions in greenhouse gas emissions, as well as more efficient power generation and improved reliability and lower maintenance costs. The objective of this cooperative agreement is to enable SunLine Transit Agency to procure and road test a 40-foot transit bus powered by a direct hydrogen fuel cell propulsion system. SunLine Transit will demonstrate and test a fuel cell transit bus with a new dbb P4 proton exchange membrane (PEM) fuel cell propulsion system. Almost 4,000 pounds lighter than its predecessor, the Phase 4 (P4) engine was designed on knowledge gained during in-service testing of buses using P3 fuel cell engines in Chicago and Vancouver, B.C. The test period for the new P4 fuel cell transit bus includes 2 months of factory testing in Vancouver followed by 13 months of on road testing at SunLine Transit.
