CNG is stored at around 3,000 psi in a compressed gaseous form rather than liquid like LPG so the cost of a storage tank many thousands of dollars more expensive than those used for Propane. Also the amount of BTUs stored in the same sized tank would be much less with CNG as you would not have the advantage of a vaporizing liquid in the tank.
The CNG delivery truck would be ultra expensive and heavy as it would have to be a tube trailer with least a 3,000 pound rating. The only way to make CNG viable is to have a pump at the end of the Natural Gas pipe line to fill the very expensive DOT approved CNG tanks in vehicles. This is why it is seen mainly in city fleets. The tax payers can afford it and it makes the mayor feel like his city is working at being greener.
If you have the ability to fill CNG tanks, you probably already have natural gas at your residence.

Finally FACTS.
CNG works if you want a tank several times bigger than a propane tank, that costs several times MORE! In a couple decades, you will break even. This is assuming you have CNG available at all. MOST areas do NOT. Very limited availability.
