The AlamedaContra Costa Transit District (AC Transit) has been operating three fuel cell buses in revenue service since March 20, 2006. This operation has been documented in previous evaluation reports from the U.S. Department of Energy (DOE), the U.S. Department of Transportation’s Federal Transit Administration (FTA), and DOE’s National Renewable Energy Laboratory (NREL). This report continues the evaluation at AC Transit; the funding for NREL’s data collection and analysis was transitioned from DOE to the FTA. Specifically, this report presents the results of AC Transit’s accelerated testing of its existing three fuel cell buses as part of the FTA’s National Fuel Cell Bus Program (NFCBP). ,992?26=:2F!&2B:>1C! The accelerated testing project at AC Transit includes preparation and support to maximize operation of the three fuel cell buses, and support of the transition to the next phase of the fuel cell bus program. The maximized operation will help the manufacturers further validate the propulsion system by identifying the weakest areas, analyzing the root causes of failure, and making modifications and upgrades to increase durability and reliability. The accelerated testing results in this report cover operation from NovemBer 2007 through February 2010 for the fuel cell buses, with a focus on fuel cell bus operations from the last installation of new fuel cell power systems (noted as the clean point). The diesel bus evaluation results are from January through December 2007. The evaluation results are summarized in TaBle ES1. This report also descriBes the achievements and challenges from nearly 4 years of revenue service. &=O?2!#Y\5R!Y0DD=6M!7X!#I=?0=:>71!"2B0?:B! '=:=!-:2D! @02?!(2??! '>2B2?!

AC Transit is moving into the next phase of fuel cell bus development, demonstrating 12 new and advanced fuel cell buses. This demonstration is in response to the California Air Resources Board (CARB) Transit rule that requires several California agencies (including AC Transit) to purchase new and advanced fuel cell buses as part of their zeroemission bus regulations. Developed by UTC Power and Van Hool, the new buses incorporate the lessons learned during the demonstration of the current fuel cell buses. AC Transit is the managing partner for a Zero Emission Bay Area (ZEBA) working group to respond to CARB’s advanced fuel cell bus demonstration. The ZEBA group includes several Bay Area transit agencies: !' AC Transit !' Santa Clara Valley Transportation Authority !' Golden Gate Transit (GGT) !' San Mateo County Transit District !' San Francisco Municipal Transportation Agency (SF MTA).1 AC Transit continues to work on developing hydrogen fueling infrastructure to support the new fuel cell buses. The Chevron station at the East Oakland Division that has been used for hydrogen fueling is scheduled for decommission in September 2010. AC Transit is working with Linde to construct new stations at East Oakland as well as its Emeryville depot (Division 2). The new Emeryville station will Be a convenient fueling location for future bus operations by ZEBA partner transit agencies like GGT and SF MTA. The current evaluation of accelerated testing at AC Transit was funded by FTA in conjunction with their NFCBP. With the completion of this report, the evaluation funding will be transitioned from FTA Back to DOE. The DOE evaluation plans include all 12 of the new fuel cell buses for the planned ZEBA/CARB demonstration. ! '''''''''''''''''''''''''''''''''''''''''''''''' 1 SF MTA is a voluntary participant. Its fleet of trolley Buses already meets CARB zeroemission Bus regulations. v &=O?2!7X!(71:21:B!
