RENEWABLE NATURAL GAS
Renewable natural gas (RNG), or biomethane, is a pipeline-quality gas that is fully interchangeable with conventional natural gas and can be used in natural gas vehicles. RNG is essentially biogas (the gaseous product of the decomposition of organic matter) made by capturing and extracting methane emissions from our waste in landfills, large animal agricultural operations, and wastewater treatment plants. RNG can be used as a transportation fuel in the form of compressed natural gas (CNG) or liquefied natural gas (LNG).
In July 2019, Clean Energy Fuels opened the first RNG fueling station in New York City in the heart of the Hunt's Point Food Distribution Center in the Bronx. Read more here.

COMPRESSED & LIQUEFIED NATURAL GAS
Compressed natural gas (CNG) is created through the process of purifying and then pressurizing natural gas to approximately 3,600 pounds per square inch. CNG can be stored on-board a vehicle in large cylinders, and can be utilized in both dedicated fuel and bi-fuel (gasoline/CNG) vehicles. CNG is used as a fuel in vehicles ranging in size from passenger cars to municipal buses.
CNG tends to be a less corrosive fuel and, therefore, reduces maintenance costs and increases the lifespan of an engine. The advantages of natural gas as an alternative fuel include its domestic availability, established distribution network, relatively low cost, and emissions benefits.
Two forms of natural gas are currently used in vehicles: compressed natural gas (CNG) and liquefied natural gas (LNG). LNG is natural gas in its liquid form. Learn more about how compressed natural gas vehicles may benefit your fleet.
