Indiana-based Green Alternative Systems (GAS) is using Luxfer Gas Cylinders' G-Stor Pro Type 3 fuel tanks to convert a fleet of Freightliner work trucks to run on compressed natural gas (CNG). According to Luxfer, the vehicles will become part of the growing fleet of CNG-powered package delivery trucks deployed by a ‘major transportation company.’
Approximately 200 of the CNG trucks were put into service in 2014, with additional conversions scheduled this year. Every truck uses two high-pressure Luxfer cylinders, each with a capacity of 1,976.8 cubic feet of natural gas compressed to 3,600 psi (248 bar).
Consisting of a proprietary aluminum liner fully over-wrapped with carbon fiber, each cylinder is 16 inches in diameter and 78 inches long. Luxfer is manufacturing the cylinders at its facility in Riverside, Calif.
“A primary reason we chose these Luxfer cylinders is that they're the lightest-weight Type 3 cylinders on the market – 16 percent lighter than other cylinders we considered,” says Mark Matijevich, GAS general manager. “Luxfer was also the only company that offered cylinders with a 25-year service life, which was another factor in our decision.”
