Gaseous Fuels

Current applications of gaseous fuels in vehicles

Propane: In current vehicle applications, there are many recreational vehicles with propane powered appliances and a modest number of vehicles that have been converted to run on propane to power the vehicle.

Hydrogen and Methane: Manufacturers are currently exploring the use of hydrogen and methane (natural gas) as fuels to power general production vehicles. There are some vehicles and fleets on the road that have been converted to methane power.

Standards

Vehicle manufacturers must comply with federal standards for crash integrity of compressed natural gas systems. FMVSS 303 regulates fuel system leakage in crashes of compressed natural gas vehicles and FMVSS 304 regulates compressed natural gas fuel container integrity when subject to over-pressurization, pressure cycling and bonfire testing.
