The Digest’s 2025 Multi-Slide Guide to Biogas Upgrading to Renewable Natural Gas

Explore biomethanation as a cost-effective method to upgrade biogas to pipeline quality renewable natural gas (RNG). This process uses naturally occurring organisms and hydrogen to convert CO2 in biogas to methane, potentially increasing production by 60-70%. NREL’s mobile RD&D platform aims to advance this technology for decarbonizing transportation and enabling long-duration energy storage. LCA shows biomethanation can significantly reduce carbon intensity compared to gas separation.
