UNSPSC 15111512: Compressed natural gas CNG

A gaseous by-product of oil used as fuel. CNG is composed of methane gas in a compressed form generally at 3,000 PSI to store as many cubic meters in the cylinders in order to provide greater autonomy to the vehicle.

UNSPSC 15111512 Compressed natural gas (CNG) Commodity code identifies products and services that state and local governments buy for vehicle fueling infrastructure, system maintenance, natural gas pipeline construction and installation, utility natural gas supply, and landfill gas upgrading.
