An LNG refueling station must have a local supply of fuel. Given that LNG is delivered by tanker truck, delivery cost and proximity of the LNG production facility are important considerations. At present, there are four LNG production facilities in Canada that can supply LNG for fleets. These facilities are located in Montréal (QC), Calgary (AB), Delta (BC), and Ladysmith (BC). A Canadian code for LNG refueling stations is currently being developed. While this work is underway, new LNG stations in Canada are being reviewed and approved based on the American LNG station code (NFPA 52).
Tanker trucks that deliver LNG must keep the fuel at -162 degrees Celsius so that it stays in a liquid state. LNG is transferred to a large, above-ground, insulated storage vessel at the refueling station. For use in a vehicle, LNG is pumped from the storage vessel, through a dispenser, into the vehicle.
- Storage vessel – tanker truck delivers LNG to storage vessel
- Cryogenic pump – moves LNG from storage to dispenser
- Dispenser – 1 or more hoses to dispense fuel to vehicles
Given that LNG is an ultra-cold fuel, there is a need to wear protective gloves and a face shield when fueling a vehicle. Basic training is required to safely dispense LNG into a vehicle.
There are three public LNG refueling stations that are soon to be open in Canada. These stations are all located in Alberta and are at truck stops operated by Shell Flying J. The stations are located in Calgary, Edmonton, and Red Deer.
There are three private fleet LNG refueling stations in Canada. One of these stations is located in Abbotsford (BC) at Vedder Transport. The other two private LNG stations support the Robert Transport fleet at their locations in Boucherville (QC) and Mississauga (ON).
