Beef Feedlots Join the Digester Ownership Map

Manure at a large cattle yard is usually a disposal problem with a smell budget attached. Energy developers have spent a decade proving the opposite model on dairies: capture methane, upgrade it to pipeline gas, and sell into transport fuel credit markets.

Last week that template showed up on a Nebraska beef feedlot at a different scale of capital. Neogenyx Fuels, the Ameresco-majority joint venture with HASI, broke ground on its first agricultural renewable natural gas plant at Adams Land & Cattle in Broken Bow. The thesis is not that digesters are new. It is that listed energy infrastructure capital will own the conversion layer at a single large cattle yard while the feedlot rebuilds pens to feed it.

Ameresco's August 31 release marks an August 26 ceremony at Adams' south lot. Neogenyx owns the facility. Adams supplies manure and keeps digestate products on site as bedding and fertilizer. The design calls for eight anaerobic digesters producing more than 4,400 standard cubic feet per minute of biogas, upgraded to about 1.2 million MMBtu of pipeline RNG a year, with a claimed annual greenhouse-gas reduction near 63,700 metric tons.

Those capacity and climate figures are company claims in the primary release. Capex is not in the Ameresco notice. Local reporting quoted Neogenyx CEO Michael Bakas saying the combined investment approaches $300 million. Treat that as a secondary figure until a filing or offtake package makes it hard.

Timing needs a clean date read. Neogenyx already said on May 19 that construction was commencing, using the same digester and MMBtu numbers. The late-August event is the public groundbreaking and political ribbon for a project that had been in development since Adams and Neogenyx first met in January 2024. For this issue, the news is that the first agricultural asset is visibly under construction, not that the molecule was invented last week.

Neogenyx is not a ranch cooperative bolting a digester onto its own books. Ameresco owns 70 percent and HASI 30 percent after a May 2026 joint-venture close that framed a $1.8 billion post-money enterprise value and a $400 million HASI growth commitment. Ameresco consolidates the vehicle. The Adams plant sits inside a balance sheet built to own and operate biofuels assets, including landfill gas projects already in the Neogenyx portfolio.

Adams is doing parallel work that makes collection possible. Local coverage describes a multi-year roller-compacted concrete rebuild of the south feedlot pens, aimed at higher capacity, less dust, and a surface that can feed digesters. When complete, that lot is expected to hold on the order of 150,000 head. The digester is the energy asset. The pen rebuild is the agricultural enabling project. Confusing the two misses where the host's capital actually goes.

The leverage point is ownership of the conversion step.

If Adams only sells manure into someone else's plant, the feedlot captures a disposal solution and nutrient products. Neogenyx captures the RNG cash flows and any credit stack attached to transportation fuel. That split is familiar from dairy digester deals. It is less common as a publicized, single-site beef feedlot flagship for a listed JV.

Most U.S. manure-to-RNG buildout still skews dairy, shaped by California LCFS economics and multi-farm clusters. EPA AgSTAR counted 191 manure-based systems already producing RNG as of mid-2024, with dozens more under construction. American Biogas Council remarks at the ceremony underscored how few Nebraska projects sit on farms today. Adams is a proof that Midwest cattle density can look like baseload feedstock to energy sponsors, not only to dairy credit aggregators.

Competitors for the host decision are other third-party developers willing to own digesters, plus the feedlot's option to self-develop or leave manure as a cost center. Competitors for the molecule buyer are dairy RNG fleets, landfill gas, and packer or brand programs that purchase methane attributes without funding a Broken Bow plant. Those are different contests. Only the first decides whether the next large yard copies Adams.

Pressure is not a cartoon fight between "agriculture" and "energy."

It is credit and contract risk. The Ameresco release points RNG at transportation and other energy uses and waves at bio-LNG for maritime markets. No offtake counterparty, tenor, or credit pathway is disclosed for this site. Without that, the plant is an engineering story with a marketing option on global shipping fuels.

It is also execution risk. Commercial operation date is absent from the Ameresco notice. The wider digester sector is not frictionless: USDA has kept a pause on anaerobic digester loan guarantees into 2026 after delinquencies elsewhere. Private HASI and Ameresco capital is not the same as a USDA guarantee, but the pause is a reminder that AD projects fail in public when feedstock, interconnect, or credit assumptions slip.

And it is replication risk. One ceremony at a sophisticated family feedlot does not prove a product. Other yards must accept multi-year pen engineering and a long-term host relationship before Neogenyx's agricultural pipeline looks like a portfolio, not a pilot.

Over the next 12 to 36 months, three tells matter more than another groundbreaking photo.

First, whether Ameresco or Neogenyx discloses COD, injected volumes, and an offtake or credit path solid enough to underwrite the 1.2 million MMBtu claim.

Second, whether a second large beef or cattle-feeding host signs a similar Neogenyx-owned digester, which would mean Adams was a template rather than a one-off.

Third, whether dairy-cluster developers or packer attribute programs absorb Midwest cattle methane without third-party digester ownership, which would shrink the host decision Neogenyx is selling.

If those break Neogenyx's way, manure at scale beef becomes contracted energy infrastructure and HASI's biofuels vehicle looks early on a new feedstock class. If credits, interconnect, or host reluctance stall after the ribbon cutting, Broken Bow remains a well-staged first agricultural asset inside a landfill-and-waste gas company that tried cattle.
