But there are two problems... 1) The gas filling station is not open to the public 2) The EPA has made it practically impossible to convert an existing vehicle to natural gas (or propane, for that matter) legally. Conversions have to be “certified” and tested, meaning they are very expensive and only available for a limited number of vehicles. In the current environment, it’s only practical for fleet usage.

Where I live in Pennsylvania that is changing. There are a few small companies that will convert a gasoline only engine to dual use for about $4,000. The vehicle will switch from one to another automatically and is EPA OK. A company called Sheetz has many filling stations throughout the region and they are in the process of adding CNG to their choice of fuels. Not a big jump, since they also sell propane gas for grills and such.

Any talk of required road taxes need to be paid?

Some folks that went to their own bio-diesel have been burned this way before.
