Interesting Facts about CNG for Cars and Trucks

For a while now, seeing the CNG sticker on a government vehicle was noticed but not given much thought. Then, seeing those space age stations that have begun to show up raised a bit more interest. Well, it was a rather interesting exploration and here are the findings in text and in image.

Natural gas is priced in a GGE unit. A unit is one gasoline gallon equivalent that

equals 5.660 lbs of natural gas. The fittings are rather straightforward; 3000psi (the blue habdle) or 3600psi (the orange handle) determines which side of the pump you use. And, if you should not know what psi stands for; well, that's straightforward too, pounds per square inch.

You can rest a bit in knowing that quantity of natural gas delivers approximately the same amount of energy to your vehicle as a typical gallon of gasoline. CNG is at a minumum 90% methane.

So, when you see the image of the pump registering 7.000 gge that means you just purchased about 35 lbs of natural gas for $19 and change. Convert that from the price of gasoline and that same amount of gasoline would have cost this past week at fill up time about $35.00.
