Analysis Indicates Fuel Economy of Fuel Cell Buses About Twice as High as Diesel Buses

January 1, 2013

A recently published NREL report—Fuel Cell Buses in U.S. Transit Fleets: Current Status 2012—indicates that the fuel economy of fuel cell buses is 1.8 to 2 times higher than conventional diesel buses (4 mpg) and compressed natural gas buses (3 mpg). This shows significant fuel economy improvement toward the U.S. Department of Energy’s and Federal Transit Administration’s target of 8 mpg (diesel equivalent).

The report is the sixth in an annual series of reports summarizing the progress of fuel cell bus development in the United States and discussing the achievements and challenges of introducing fuel cell propulsion systems in transit applications.
