Renewable Natural Gas Production (RNG)

« Back to Glossary Index« Back to Previous Page

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:
Biogas Upgrading, Sustainable Gas, Net-Zero Energy

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