Washington D.C. – The farm lobby is actively advocating for significant tax credits to incentivize the production of renewable natural gas (RNG) derived from dairy and corn, a move that could reshape the clean energy landscape. This legislative push aims to bolster the use of biomethane, a pipeline-quality gas produced from organic waste, with California leading the nation in compressed natural gas (CNG) stations poised to utilize this fuel.
The initiative centers on securing tax credits, including the proposed $1.00 per gallon equivalent for RNG used as transportation fuel, as outlined in the bipartisan Renewable Natural Gas Incentive Act (S. 1252/H.R. 2596) introduced in April 2025. This legislation seeks to provide direct financial incentives, moving beyond the mandate-based system of the Renewable Fuel Standard. Renewable natural gas facilities are also eligible for investment tax credits (ITCs) and production tax credits (PTCs) under the Inflation Reduction Act of 2022, further supporting their development.
The agricultural sector, particularly dairy and corn producers, stands to benefit significantly. RNG is generated through anaerobic digestion, where organic materials like manure and agricultural residues break down to produce biogas. This biogas is then upgraded to pipeline-quality methane. Dairy farms, for instance, can capture methane from cow manure that would otherwise be released into the atmosphere, turning a potent greenhouse gas into a valuable energy source. This process offers farmers an additional revenue stream and contributes to sustainability efforts.
The tweet from Kumar🇺🇸, directed at @anasalhajji, highlighted this trend:
"@anasalhajji the metrics on CNG stations are getting steam from the farm lobby that's pushing tax credits for dairy and corn produced natural gas - referred to as renewable natural gas. California has the most CNG stations."
Organizations like the RNG Coalition actively lobby the Environmental Protection Agency (EPA), Department of Agriculture, and Congress to advance policies supporting RNG. They emphasize the environmental benefits, such as carbon-negative outcomes when RNG fuels on-road vehicles, as confirmed by California Air Resources Board data. This lobbying ensures that agricultural waste-to-energy projects receive the necessary policy and financial backing.
California, with its extensive network of CNG stations and progressive clean fuel programs like the Low Carbon Fuel Standard (LCFS), is a key market for RNG. The state's policies have already spurred investment in biomethane projects, particularly from dairy farms, and are expected to drive further adoption as federal incentives materialize. The increasing availability of these tax credits and the growing demand for cleaner transportation fuels are creating a robust market for agriculturally-sourced RNG.
