Energy Issue

I forget what the technical terms are, but CNG doesn't provide as much energy as gasoline when it burns. So you need to use more CNG to get the same amount of power as gasoline. The reason CNG isn't much more common as vehicle fuel is that you need a tank the size of the passenger compartment to hold enough of it to do the same work as a 20-gallon gas tank.

Also, natural gas is a fossil fuel with finite resources just like gasoline. Substituting it would just be a band-aid on a gaping flesh wound.
