NFCBP III: AC Transit Extended Operations & ZEBA

AC Transit is managing a partnership of San Francisco bay area transit operators interested in deploying zero emission fuel cell buses in their areas.  These partners include Santa Clara Valley Transportation Authority (VTA), Golden Gate Transit (GGT), San Mateo County Transit District (SamTrans), and San Francisco Municipal Railway (Muni).  Under the ZEBA program, 12 Van Hool buses powered by UTC fuel cells will be operated by AC Transit and neighboring transit groups.  GGT began operating buses after the opening of the Emeryville station, and VTA and SamTrans began operations when the second station opened in 2013.  Three of these buses utilize fuel cell power systems from AC Transit's original Van Hool buses, the remaining nine have new fuel cell systems.  NREL recently released performance results for these buses. In 2013, this project was extended to fund continued operation of the AC Transit buses. The fleet is now the largest and most successful collection of fuel cell buses in the United States.
