An at home CNG refueling station is prohibitively expensive. Both in purchasing cost and permitting fees. They are also extremely slow (about 8-12 hours to refuel). CNG tanks take up a good deal of space, especially when used as a duel fuel system. If you use the high speed fills on CNG, you lose about 50% of the tank capacity. The government grants (that you pay for btw with your tax dollars) apply only to new vehicles. Not for conversions to existing vehicles. The emissions laws regarding equipment does not change when you convert to CNG or LP. Ie, the cat must stay in the exhaust system, as must the carbon cannister, egr and such. Regardless of whether or not the vehicle even has a gas tank left after conversion. Only battery powered electric vehicle can legally remove things like the cat and carbon can. CNG systems are in use in the US, but almost exclusively in fleets that are driven locally, and have the refueling capability. Propane systems are in use, and tend to work well, if done well. Similar CNG or LNG (what a monster LNG is btw). CNG and LP are both common in Europe, with LP possibly being more common. It is far and away more common in the US then CNG, particularly if you include farm equipment. As for road tax, there's road tax on natural gas when it's used for on road vehicles.
