The Digest’s 2024 Multi-Slide Guide to Biomethanation to Upgrade Biogas to Pipeline Grade Methane

Renewable natural gas (RNG) is typically produced from biogas using gas separation technology – keeping the CH4 – venting the CO2. Upgrading CO2 present in biogas using naturally-occurring organisms can  increase production 60 – 70%. In this project, researchers aimed to develop, innovate, reduce costs and de-risk the biomethanation process to upgrade biogas sources to pipeline quality natural gas for long-duration energy storage and decarbonization of the transportation sector. Kevin Harrison and Nancy Dowe of NREL gave this presentation on the project at DOE Project Peer Review.
