CNG Fueling

At CNG stations, the gas is typically taken from the local gas utility’s line at low pressure, compressed and dispensed into the vehicle's storage tanks at high pressure, typically to 3,600 psi. There are two basic types of fueling equipment: fast-fill and time-fill.

  • Fast-fill systems combine a compressor and a high-pressure storage system. The storage system, called a cascade, fills the vehicle's fuel tank in about the same time it takes to fuel a regular vehicle.
  • Time-fill systems do not have a storage system and typically compress the gas directly into the vehicle storage cylinders to refuel vehicles while they are parked overnight.

Public CNG stations are currently limited but the number of locations is expanding rapidly. Individual consumers or public/private fleet operators may also choose to install their own CNG fueling stations.
