AC Transit's Fuel Cell Program Breaks 25,000 Hour Operating Record


Fuel Cell Electric Bus #7 has exceeded federal targets – achieving 25,000+ hours of operation


OAKLAND - The Alameda-Contra Costa Transit District (AC Transit) recently recorded a second history making event – 25,000 hours of continuous operation of a Fuel Cell Electric Bus or FCEB #7. Just two years ago, the FCEB power plant set an international record for 20,000 hours of continuous operation. With each record setting accomplishment, AC Transit has dramatically advanced alternative fuel vehicles by both proving the durability of hydrogen fuel cell in daily revenue service and remaining at least one year ahead of federal recommendations.

“The fuel cell manufacturer expected the onboard power plant to operate just 4,000 hours,” says AC Transit Board Director Chris Peeples. “But we’ve created a team of maintenance professionals who have been industry leaders in FCEB and Zero Emission Bus (ZEB) technology; proving FCEB’s are a dramatic leap forward in meeting the Advanced Clean Transit Regulations target of operating all zero-emission buses by the year 2040.”
 
The U.S. Department of Energy and Federal Transit Administration established performance metrics and life expectancy for FCEB’s. Traditionally, a public transit buses life expectancy is measured in terms of the number of miles on its diesel engine. A diesel engine’s life expectancy is 6 years or 250,000 miles before overhaul. However, the Fuel Cell Electric Bus (FCEB) reinvented the heavy duty transit model. FCEB’s eliminated the harmful CO2 emissions of diesel engines with its zero-emission onboard power plant. Now, the life expectancy of the fuel cell power plant is measured in terms of hours. Once AC Transit’s FCEB#7 recorded its 25,000-hour milestone, it demonstrated the potential for fuel cells to meet the equivalent life cycle expectancy similar to a diesel engine.

“Since 2001, AC Transit’s FCEB’s continue to prove that there is a zero-emission alternative to diesel engines with near identical durability,” said California Air Resources Board Chair Mary D. Nichols. “The 25,000 hours of AC Transit’s FCEB says to public transit agencies around the state, alternative fuel vehicles can and will accomplish the heavy demands of daily service while meeting CARB’s efforts to curtail air pollution statewide.”
 
FCEB #7 is one of thirteen zero-emission buses operated by AC Transit. The National Renewable Energy Laboratory (a national laboratory of the U.S. Department of Energy Office of Energy Efficiency & Renewable Energy) documents a series of successes of the AC Transit FCEB fleet including:

“The record breaking success of FCEB #7 underscores the importance of the recently announced Fuel Cell Electric Bus Commercialization Consortium (FCEBCC),” says Dan Raudebaugh, Executive Director of the Center for Transportation and the Environment (CTE). “The FCEBCC will deploy 20 zero-emission fuel cell electric buses between northern and southern California.  CTE is excited to provide project management oversight for this important project that demonstrates there is a clear business case for industry to invest in clean innovative technologies.”

To better demonstrate AC Transit’s trailblazing work in the proactive use of zero-emission buses for daily revenue service, a FCEB traveled to Reno, Nevada in support of the APTA 2017 Bus & Paratransit Conference. While the Bay area has a variety of microclimates and terrains, generally the weather is mild and hilly topography is gradual. So after 16 years of continuous operation in these conditions, Reno was an opportunity for our maintenance professionals to test the FCEB’s durability in inclement weather and steeper terrain. As a result, one of our 13 fuel cell buses drove 224 consecutive miles. The FCEB traveled, virtually nonstop, in rain and snow flurries. Perhaps the FCEB’s most impressive accomplishment was its ability to climb the 7057 foot Donner Pass. In fact, the FCEB beat all the odds: averaging 10.91 miles per gallon and completing the Reno drive in just over five hours. This trip helped demonstrate how zero-emission hydrogen fuel cell buses can be a one-for-one replacement for diesel or CNG coaches.
