Natural Gas Refuelling Stations

Canada's Public Station

Enbridge_Refuelling1Canada has a network of approximately 80 public refuelling stations located in five provinces. All of these stations dispense natural gas in compressed form at 3,000 pounds per square inch (psi), the pressure which is allowed within the current Canadian codes and standards. The majority of natural gas refuelling is located at existing retail gasoline  that have a separate refuelling island for natural gas.

Public Station Pricing

Federal regulations require that natural gas be dispensed on a cents per kilogram basis. To convert the pump price in order to compare directly with gasoline pricing on an energy equivalent basis, divide the per kilogram pump price by 1.516. One kilogram of natural gas has the same amount of energy as 1.516 litres of gasoline.

Compressed Natural Gas (CNG) Stations


A compressed natural gas (CNG)  refuelling station can be installed wherever there is a natural gas pipe in the ground. Canada has an extensive network of  underground infrastructure that delivers natural gas within most communities. Stations may be publicly accessible at retail sites or installed at private sites to serve fleets whose vehicles return to the yard at night. Some of Canada's natural gas utilities work with fleets to install refuelling stations. There are also equipment and refuelling station providers who install refuelling stations and, in some cases, finance the capital cost of the stations.

There are two main types of CNG refuelling systems - fast fill and time fill. Fast fill stations dispense CNG at rates comparable to liquid fuels. These stations have large compressors as well has high pressure fuel storage tanks to support rapid vehicle refuelling. Time fill stations do not have storage tanks and they incorporate smaller  compressors. Vehicles are plugged in at filling posts for overnight refuelling at the fleet owner's site. No special training is required to refuel a vehicle at either a public or private CNG refuelling station.

Liquefied Natural Gas (LNG)

Liquefied natural gas (LNG) refuelling stations rely on bulk delivery of fuel via tanker trucks similar to the way in which gasoline and diesel are delivered to refuelling stations. As LNG needs to be stored at -160 Celsius in order to stay in a liquid state, the fuel is delivered to the station site and stored in a special insulated cryogenic tank. The fuel is pumped from the storage tank and dispensed in a way that is similar to liquid fuels. As LNG dispensers operate at cryogenic temperatures, training is needed in order to dispense the fuel safely. Protective gloves and face shields must also be worn by personnel.

Canada has two private LNG vehicle refuelling stations and one public station with GazMétro - one at Westport Innovations which is  used to refuel test vehicles and the other at Terasen Gas in Delta, BC. The lack of commercially-available LNG in Canada coupled with the existence of a very extensive underground natural gas distribution system have limited the development of LNG refuelling station infrastructure in Canada. This situation is expected to change within the next year or so as two of Canada's natural gas distribution companies begin to supply LNG for the  heavy truck market. GazMétro has an LNG public station in Cornwall, ON at 2550 Industrial Park Drive, H6H 7N1.
