What is renewable natural gas and how can it be used to fuel vehicles?
Renewable natural gas (RNG) is pipeline-quality natural gas made by collecting and purifying biogas, the methane produced from decomposing organic matter. Biogas can be collected from sources such as landfills, livestock operations, wastewater treatment plants, food manufacturing and wholesalers, supermarkets, restaurants, and hospitals. Once purified to remove contaminants and increase its heat content, the gas is called RNG and is a “drop-in” fuel that can be transported with conventional natural gas in pipelines, dispensed at the same fueling stations, stored in the same storage tanks, and used in natural gas vehicles without any engine modifications.
Despite its advantages, there are only 60 operational
