Definition:
A process that converts organic waste (biogas) into pipeline-quality natural gas through purification and upgrading.
Key Components:
- Anaerobic Digestion: Uses bacteria to break down organic waste and produce biogas.
- Gas Upgrading: Removes CO₂, water, and contaminants to meet pipeline specifications.
- Injection & Distribution: Blends RNG with conventional natural gas for transport.
Use Cases/Industries:
- Sustainable Energy: Provides a renewable alternative to fossil natural gas.
- Waste Management: Converts landfill gas and agricultural waste into energy.
- Transportation: Used as compressed natural gas (CNG) for low-carbon vehicles.
Advantages:
- Carbon Neutral: Captures methane from waste sources.
- Distributed Production: Can be generated near consumption points.
- Government Incentives: Qualifies for renewable energy subsidies.
Challenges:
- High Processing Costs: Requires advanced gas upgrading technology.
- Feedstock Limitations: Availability of organic waste affects production scale.
- Infrastructure Needs: RNG injection points must connect to natural gas networks.
Related Terms:

Example:
A dairy farm installs an anaerobic digester to produce RNG from manure, selling it as a renewable transportation fuel.
