What you are looking at
CNG is natural gas compressed to around 200 bar, almost pure methane, dispensed and billed by the kilogram rather than by the litre. You pay per kilogram, and a kilo goes roughly as far as a litre and a half of petrol, so the price per kilo means nothing until you do that sum.
It is fitted to factory bi-fuel cars and vans and to a large share of city buses; converting a car afterwards is rare, because the tank is a pressure cylinder. The network is concentrated around the big cities and the freight corridors, and several provinces have no public refuelling point at all.
