I am currently in the process of getting my own CNG station up and running. The last numbers I saw on natural gas prices was something around $3.00/M . According to this chart, the current price is something in that vicinity.
Given that the "M" refers to a thousand cubic feet of gas, and since a "gallon" equivalent of natural gas is about 120 cubic feet, then the price per gallon of natural gas out of the pipeline ought to be about $0.36/gallon.
Add on to that a nominal pumping cost and you are probably looking at 40 cents per gallon.
Multiply times 10, and you get $4.00/ gallon, which is what Diesel is selling for in a lot of places right now.
