Renewable natural gas (RNG) is a pipeline-quality gas that can be used in place of conventional natural gas. It's produced from organic waste through a biochemical process, such as anaerobic digestion, or through thermochemical means, such as gasification.
Here are some things to know about RNG:
Sources
RNG can come from a variety of sources, including landfills, livestock waste, wastewater treatment plants, and food waste. Landfills are the largest source of RNG, accounting for over 90% of production.
Process
RNG is produced by breaking down organic matter in an oxygen-free environment to produce biogas, which is then processed to remove impurities. The resulting gas is nearly pure methane.
Uses
RNG can be used for a variety of purposes, including electricity generation, heating, cooking, bioplastics, and vehicle fuel.
Benefits
RNG projects can reduce carbon emissions by offsetting the use of geological natural gas and preventing methane from entering the atmosphere.
Status
RNG is an advanced biofuel under the Renewable Fuel Standard. In North America, there are currently more than 300 RNG facilities in operation.
