The big problem with CNG is that the energy density of the stored fuel
is small compared with gasoline and diesel. So you might need a 100
gallon high pressure tank to equal a 35 gallon diesel tank. That can be
a big problem for a car, not so big for a duece or 5 ton. A lot of
cities are going to CNG use in government vehicles. Propane conversions
are a lot cheaper since the pressures are a lot lower. Also filling up
a CNG vehicle can be tough on the open road, although there are a few
filling locations that I have seen at truck stops.
