Researchers from the National Renewable Energy Laboratory, commissioned by the California Air Resources Board (ARB), have issued their initial evaluation of the hydrogen fuel cell buses in operation at BC Transit. The report covers two years of revenue service data on the buses from April 2011 through March 2013.
In 2012, NREL developed a guideline for evaluating the technology readiness level (TRL) for fuel cell electric buses (FCEBs). TRLs range from concept design at TRL 1 up to full commercialization and deployment at TRL 9. Using this guide, the NREL team assessed the BC Transit buses to be at TRL 7: full-scale validation in a relevant environment. During the two-year data period analyzed for the report, the FCEB fleet accumulated more than 2.1 million kilometers (1.3 million miles) and more than 156,000 hours on the fuel cell power plants. Overall the FCEBs have an average fuel consumption of 15.48 kilograms of hydrogen per 100 kilometers. This equates to a fuel economy of 4.53 miles per diesel gallon equivalent (mi/DGE). The buses have an average availability of 69%.Click Here for more Information
