Renewable natural gas

Renewable natural gas (RNG), also known as biomethane, is a renewable fuel and biogas which has been upgraded to a quality similar to fossil natural gas. More than 300 RNG facilities are currently operational in North America, with more than 70% of supplies drawn from the MSW and landfill sectors. RNG can be used in existing appliances, including vehicles with natural gas burning engines. It can also be converted into liquefied natural gas or compressed natural gas for direct use as fuel in transport sector. The first commercial RNG facility was launched at the Fresh Kills landfill near New York City in 1982. A study commissioned by the American Gas Foundation and executed by ICF in 2019 projected that between 1.6-3.78 trillion cubic feet of RNG could be produced annually for pipeline injection in the U.S. by 2030. The Environmental and Energy Study Institute estimated that renewable natural gas could replace up to 10% of all natural gas used in the United States, and a study by the National Association of Clean Water Agencies and the Water Environment Federation found that the quantity of biosolids removed from wastewater could be turned into enoughBiogas to potentially meet up to 12% of America's national electricity demand.
