DOE Report Analyzes Fuel Cell, Diesel and CNG Fuel Economy
by Lauren Tyler (NGT News) The U.S. Department of Energy’s (DOE) Fuel Cell Technology Office recently released a report showing that the average fuel economy of fuel cell electric buses from three fleets is approximately 6 miles per diesel gallon equivalent (DGE), 1.4 times higher than conventional diesel buses (approximately 4.2 miles per DGE) from one fleet and up to 1.9 times higher than compressed natural gas (CNG) buses (approximately 3.3 miles per DGE) in another fleet.
According to the DOE, this finding demonstrates significant fuel economy improvement toward the department and the Federal Transit Administration’s target of 8 miles per DGE.
The report notes that fuel cell electric bus durability has reached 23,000 hours, surpassing the technology office’s 2016 target of 18,000 hours, and range has reached up to 340 miles, more than 13% above our 2016 target of 300 miles.
The report, entitled Fuel Cell Buses in U.S. Transit Fleets: Current Status 2016, published annually by the National Renewable Energy Laboratory, summarizes the progress of fuel cell electric bus development in the U.S. and discusses the achievements and challenges of introducing fuel cell propulsion in transit.
