Compressed natural gas (CNG) is dispensed slowly from a compressor to the vehicle’s onboard storage tank. This type of fueling station is best for fleets that return to a central location and sit idle overnight or for extended periods. Typical fueling time is 6-8 hours.

These stations are similar to a typical gas station. The vehicle receives natural gas directly from a storage system. This type of station is for public-access refueling and is also ideal for larger fleets where fueling turnaround time is short.

Nexus is a fast-fill, public fueling station that received funding from National Fuel and worked with seven businesses to bring CNG fueling to the Tonawanda, NY, area.

Tops Markets leases freightliner CNG tractors and operates a private fast-fill station to significantly reduce fuel costs for their delivery fleet.
