Propane Vehicle Conversions

Related Information

Vehicle conversions help expand the alternative fuel options for fleets. Certain light-duty propane vehicles can be ordered from a dealer. A qualified system retrofitter (QSR) can also reliably convert certain in-service light-, medium-, or heavy-duty vehicles for propane operation. Ford’s Qualified Vehicle Modifier program is an example of this. Conversion systems must be certified as compliant in accordance with U.S. Environmental Protection Agency (EPA) regulations. EPA lists these systems as Certified Clean Alternative Fuel Conversion Systems.

Propane vehicle conversions in the United States require EPA certification, and a QSR should perform the installation. For more information about regulations, codes, and standards, see the Vehicle Conversions page.

The National Renewable Energy Laboratory recently produced What Fleets Need to Know About Alternative Fuel Vehicle Conversions, Retrofits, and Repowers. The report discusses important considerations, “Pro Tips,” and best practices for converting vehicles to run on alternative fuels, including propane.

The upfront costs to convert fleet vehicles to propane can be offset by lower operating and maintenance costs over the lifespan of the vehicles and, in some states, by tax credits or grants. Propane can be a cost-effective option when considering the overall cost per mile to operate a propane vehicle.
