Questar Fueling Company, a subsidiary of Questar Corporation, opened the nation's largest compressed natural gas (CNG) fueling facility in Houston, Texas. It will serve up to 200 class-8 natural gas-powered trucks operated by Central Freight Lines and Swift Transportation. It will also be open to other fleets and the general public who drive natural gas vehicles (NGVs).
Central Freight Lines and Swift Transportation are projected to use about 5 million diesel-gallon equivalents of natural gas per year. The majority of the trucks will use a private time-fill facility in which the trucks fill when parked. The remainder will use a five-lane, high-speed-fueling facility with public access for anyone driving an NGV.
