Natural gas vehicles can be refuelled at dispensers, similar to those designed for diesel or gasoline vehicles. There are more than 1,200 CNG refuelling stations in the U.S. including public service stations and private depot-based refuelling stations for fleets. Several companies provide CNG/LNG refuelling infrastructure to fleets on a component or turnkey basis.
A typical CNG station includes a compressor, a gas dryer, storage vessels, dispensers and underground piping. In most cases, a CNG station is created by connecting a fuel compressor to the nearest underground natural gas pipeline distribution system.
There are two types of CNG fueling stations: fast-fill and time-fill. Fast-fill stations
operate at higher pressures and take a similar amount of time as a diesel to fill. The
amount of gas flowing through the filling lines creates some heat, which can reduce
total fuel capacity. Time-fill stations can refuel a fleet of vehicles at a single location over a longer time period. These filling stations use lower fuel pressures, with multiple vehicles being plugged in for several hours, similar to a battery on a trickle charger. This eliminates the problem of drivers waiting in line for a limited number of fuel pumps, minimizes labor and ensures a full fill at up to 3600 psi.
A typical LNG station includes LNG storage, a pump/dispenser, and underground piping. The fuel is dispensed as a liquid into vehicle storage tanks similar to conventional liquid fuels. Because LNG is stored at extremely cold temperatures, when fueling an LNG-powered vehicle, operators must wear protective gloves and clothing to avoid freezing burns. Fueling is done through a top-mount cap, and takes a similar amount of time to fill as a diesel tank.
