Fleets that choose natural gas have a range of refueling station options and a choice of service providers for vehicle refueling. Stations dispensing compressed natural gas (CNG) can be designed as fast fill stations capable of matching the filling times of liquid fuels or time fill stations that refuel all vehicles simultaneously with refueling typically taking place overnight in the fleet yard. Liquefied natural gas (LNG) stations refuel vehicles in times similar to diesel station refueling.
Refueling at an existing public CNG refueling station may be an option at the early stage of switching to natural gas. If a public station is to be used, fill time and site access are important considerations.
Private onsite CNG or LNG refueling stations may be suitable if the fleet’s total natural gas fuel volume is sufficient. A simple rule of thumb is that typically 20 medium or heavy vehicles are needed in order to consider a private onsite station.
Another refueling option may involve accessing a nearby private station owned by another fleet.
