Typically, RNG injected into a natural gas pipeline has a methane content between 96 and 98 percent. Once upgraded, the gas has a methane content of 90 percent or greater. Treatment includes removing moisture, carbon dioxide (CO 2) and trace level contaminants (including siloxanes, volatile organic compounds, or VOCs, and hydrogen sulfide), as well as reducing the nitrogen and oxygen content. ![]() Raw biogas has a methane content between 45 and 65 percent, depending on the source of the feedstock, and must go through a series of steps to be converted into RNG. RNG can be used locally at the site where the gas is created or it can be injected into natural gas transmission or distribution pipelines. Show/Hide Data RNG Projects Operating by Year Year Landfill and Agriculture RNG Projects in the United States (2005-2021) The biogas used to produce RNG comes from a variety of sources, including municipal solid waste landfills, digesters at water resource recovery facilities (wastewater treatment plants), livestock farms, food production facilities and organic waste management operations.Īs a substitute for natural gas, RNG has many end uses: that has been upgraded for use in place of fossil natural gas. The principal constituents are methane and carbon dioxide. ![]() Renewable natural gas (RNG)* is a term used to describe biogas biogasGas resulting from the decomposition of organic matter under anaerobic conditions. ![]()
