Renewable Natural Gas as an Emerging Industry
Renewable natural gas (RNG), also called biomethane, is pipeline-quality methane gas produced from organic waste sources through anaerobic digestion or thermal gasification, then upgraded, conditioned, and injected into the natural gas pipeline system or used as a transportation fuel. RNG is chemically identical to conventional natural gas and can be used interchangeably in any application that burns natural gas, including power generation, industrial heating, commercial and residential heating, and as a vehicle fuel in compressed natural gas (CNG) and liquefied natural gas (LNG) vehicles. What distinguishes RNG from conventional natural gas is its origin: RNG is produced from organic waste that would otherwise decompose and release methane (a potent greenhouse gas) into the atmosphere, making RNG a carbon-negative fuel in many lifecycle analyses because it captures methane emissions that would have occurred regardless.
The US RNG industry has grown rapidly in recent years, driven by federal and state policy incentives that make RNG production economically attractive. At the federal level, the Renewable Fuel Standard (RFS) program requires petroleum refiners and importers to blend increasing volumes of renewable fuels (including RNG used as a transportation fuel) into the US fuel supply, and RNG producers generate Renewable Identification Numbers (RINs) that can be sold to obligated parties for $1-3+ per gallon equivalent. At the state level, California's Low Carbon Fuel Standard (LCFS) program provides additional credits for low-carbon transportation fuels, and RNG from dairy manure (which has a very negative carbon intensity score due to the methane emission avoidance) can generate LCFS credits worth $100-200+ per metric ton of CO2 equivalent avoided, making dairy RNG projects extraordinarily profitable. Oregon, Washington, and several other states have adopted or are developing similar low carbon fuel standard programs.
The combination of RFS RINs and LCFS credits can make RNG worth $20-40+ per MMBtu to producers, compared to conventional natural gas prices of approximately $2-5 per MMBtu, creating enormous economic incentives for RNG project development. This value premium has attracted billions of dollars in investment from energy companies (BP, Shell, TotalEnergies, Chevron, and others have all made significant RNG investments), waste management companies (Waste Management/WM, Republic Services, and others are developing RNG projects at their landfill gas facilities), agricultural companies, and dedicated RNG developers.
EPA AgSTAR and LMOP Databases
The EPA operates two programs that maintain the most comprehensive publicly available databases of biogas and RNG projects in the United States. The AgSTAR program (a voluntary outreach program promoting biogas recovery and use at livestock operations) maintains a database of approximately 300+ operational agricultural anaerobic digester projects, along with information about digester technology type, feedstock (dairy manure, swine manure, poultry litter, food waste co-digestion), biogas utilization (electricity generation, RNG upgrade, direct use for heating), and project developer and operator contacts. The database also identifies approximately 8,000+ additional farms that are candidates for anaerobic digester projects based on herd size, location, and other factors, providing a prospecting database for companies that develop, engineer, or supply equipment for new agricultural digester projects.
The Landfill Methane Outreach Program (LMOP) maintains a database of approximately 2,500+ operational landfill gas-to-energy projects (including both electricity generation and RNG upgrade projects) and identifies approximately 500+ additional landfills that are candidates for landfill gas energy projects. The LMOP database includes information about landfill size, waste-in-place tonnage, estimated gas generation, current gas utilization, project developer, and contact information. Many existing landfill gas-to-electricity projects are being converted to RNG production because the economics of RNG (driven by RINs and LCFS credits) have become significantly more favorable than the economics of landfill gas electricity generation.
Navigate to EPA AgSTAR livestock anaerobic digestion database, EPA LMOP landfill gas energy project database, and the American Biogas Council (ABC) member directory and project database. Save AgSTAR and LMOP project database entries, including project profiles and contact information, as HTML or download as available data files. Upload to Email Extractor to extract project developer, farm operations manager, landfill gas director, and environmental compliance manager email addresses from EPA biogas project databases for anaerobic digestion equipment, gas upgrading systems, and RNG project development services outreach.
Dairy and Livestock Manure-to-Energy Projects
Dairy and livestock manure anaerobic digestion represents the highest-value segment of the RNG market because of the extremely negative carbon intensity scores assigned to dairy manure RNG under the California LCFS program. Dairy manure that decomposes in open lagoons or storage structures releases methane directly into the atmosphere, and by capturing this methane through anaerobic digestion and upgrading it to RNG, producers generate carbon credits based on the methane emissions avoided. The carbon intensity score for dairy manure RNG can be as negative as -300 to -500+ grams of CO2 equivalent per megajoule, compared to conventional natural gas at approximately +80 gCO2e/MJ, making dairy RNG one of the most carbon-beneficial fuels available under any carbon accounting framework.
This extraordinary carbon credit value has made dairy RNG projects the most profitable renewable energy projects available to dairy farmers, with large dairy operations (1,000+ cows) potentially generating $1-5+ million or more in annual revenue from a combination of RNG sales, RIN credits, and LCFS credits. Major dairy RNG developers include Montauk Renewables (one of the largest RNG producers from agricultural sources, operating multiple dairy digester projects), Vanguard Renewables (a dairy RNG developer operating projects across the eastern US), Brightmark (which develops large-scale dairy digester projects in partnership with major dairies), California Bioenergy (CalBio, a developer focused on California dairy digesters), and numerous smaller developers.
Navigate to California Air Resources Board (CARB) LCFS pathway application database (which identifies all RNG projects that have applied for or received LCFS pathway certification, including detailed project descriptions and developer information), EPA RFS RIN generation data (which tracks RNG production volumes by facility), and state agricultural department and environmental agency databases listing permitted or operating anaerobic digesters. Save LCFS pathway applications and RIN generation reports as HTML or PDF. Upload to Email Extractor to extract dairy operations manager, RNG project developer, environmental engineer, and business development director email addresses from dairy RNG project databases for digester equipment, gas upgrading systems, and carbon credit brokerage services outreach.
