PHILADELPHIA (CBS) – A natural gas industry group has created what it calls a “roadmap” to putting Pennsylvania’s huge Marcellus Shale natural gas reserves to use in transportation.

This is a chicken and egg situation. Natural gas powered vehicles are available now, but filling stations are rare so the Marcellus Shale Coalition’s “Roadmap” lays out ways to encourage refueling infrastructure for commercial vehicles, which might entice consumers to buy a natural gas car.

Steve Forde, the Coalition’s Policy and Communications Director, says there’s a way to use either natural gas or gasoline, “There are a number of bi-fuel vehicles on the market right now and from the actual cost of the vehicles and the usability of those vehicles, bi-fuel vehicles have becomes quite prevalent not only in Pennsylvania but elsewhere as well.”

Advantages of natural gas as vehicle fuel include domestic production, cleaner operation and current cost equivalent of less than $2 a gallon.
