The Renewable Fuels and Lubricants (ReFUEL) Laboratory is a world-class testing facility dedicated to advanced fuels and vehicles research. The lab features a chassis dynamometer for vehicle performance and emissions research, two engine dynamometer test cells for advanced fuels research, and precise emissions analysis equipment. As a complement to these capabilities, detailed studies of fuel properties, with a focus on ignition quality, are performed at NREL's Fuel Combustion Lab.

Because the ReFUEL Laboratory is located in Denver, Colorado, it offers the additional capability of testing emissions and vehicle performance at high altitude. It also features an altitude simulation system to mimic results found at lower altitudes, including sea level.
