Just as with natural gas vehicles, natural gas station technologies have improved since first being introduced in Canada more than 30 years ago. Natural gas vehicles can be refueled in a similar length of time to diesel or gasoline vehicles. Natural gas refueling stations can be sized according to fleet refueling time needs. There are a range of station options including public, cardlock, private, and private with a public access dispenser.
A typical compressed natural gas (CNG) refueling station will dispense fuel at a rate of 18 to 35 litres per minute. A typical liquefied natural gas (LNG) refueling station dispenses fuel at an even higher rate. With CNG vehicles, fleets also have an option of refueling vehicles overnight using a time fill system that fills all vehicles within an 8 to 12 hour window.
Natural gas fueling stations are subject to strict regulatory requirements similar to what is required for gasoline and diesel fuel stations. There are codes and standards that define both equipment and installation requirements to ensure public and worker safety and to limit noise and protect the environment. Provincial authorities review and approve all new natural gas station installations. Fleets can work with their station equipment or natural gas fuel supplier in order to determine what the local requirements are for station installation and approval.
