International Fuelcellbus Collaborative

NFCBP |: Nutmeg

This NFCBP project entails the demonstration of four Van Hool buses with UTC Power fuel cell systems and a Siemens hybrid drive integrated by the bus manufacturer. The first of four buses was delivered in May 2010 to CTTransit and NREL has been collecting and reporting data since then. These buses are the same configuration as the ZEBA program buses in San Francisco.  One or more of these buses will be demonstrated at other US transit agencies.  In May 2012 Mass Transportation Authority (MTA) in Flint, Michigan began operating one of the buses.   Cleveland, OH Regional Transit Authority (RTA) also took delivery of one of the buses in 2013.  NAVC manages the Nutmeg project.

H2 Fueling Infrastructure

CTTransit primarily fuels at an off-site UTC Power station.  In 2011, CTTransit added a small fueling facility that can dispense 30kg/day.

In Michigan, Air Products built an expandable fueling station in Grand Blanc township that utilizes an on-site electrolyzer to support the MTA operated bus.
