Fischer-Tropsch Diesel

In association with NREL's Nonpetroleum Based Fuels team, the Fleet Test and Evaluation team worked with bottled-water distributor Yosemite Waters to determine the impact of Fischer-Tropsch diesel on the emissions and operations of six 2001 International Class 6 trucks.

Also known as a gas-to-liquid fuel, Fischer-Tropsch diesel is created when a gaseous fuel is converted into a liquid and refined to make diesel or gasoline. Interest in this fuel growing due to its ability to reduce emissions and its compatibility with advanced emission control devices.
