There are a lot of alternative fuel vehicle options competing for millions of dollars in VW funding. Twenty-nine state agencies are reviewing comments and are in the process of finalizing plans to allocate funds from the Volkswagen Mitigation Trust. Fleet managers, transportation directors, and propane retailers must respond during the comment period and encourage their state officials to include the alternative fuel that is proven to be an environmental and economic success: propane autogas. In fact, the versatile fuel can reduce NOx emissions in a variety of applications when compared with diesel vehicles.

For school buses in particular, those equipped with Roush CleanTech’s new .05 low-NOx engine reduces this targeted pollutant more than any fuel system, including new clean diesel and CNG. According to Roush, the Ford 6.8L engine is 99 percent cleaner than pre-2007 model year buses — many of which are still in operation — and 75 percent cleaner than recent “clean diesel” systems.

For state agencies considering new diesel systems, propane autogas engines do not require additional fluids or filters to reduce emissions. Propane is non-toxic and a non-contaminant of air, land, and water resources. And propane autogas is a proven technology with decades of successful deployment as a primary fuel source.

Other benefits that fleets are receiving from propane autogas include:

  • The lowest total cost-of-ownership over the vehicle’s lifecycle, which provides more savings to the owner for additional resources.
  • Significantly reduces the student and driver exposure to harmful pollutants and particulate matter or operators driving delivery vans, work trucks, transit buses or other diesel-powered vehicles.
  • The most affordable infrastructure with both private and public refueling options.
  • Propane autogas has a significant, positive impact on their state’s economy.
