Redtail Renewables

What Redtail Renewables does

Redtail Renewables is a private renewable natural gas (RNG) developer and operator founded in May 2023 and headquartered in Indianapolis, Indiana. The company converts fugitive methane captured from municipal landfills into pipeline-quality renewable natural gas for sale to logistics, industrial, and utility customers under long-term commercial offtake agreements. Its core operating asset is the Owensboro RNG project at the West Daviess County Landfill in Kentucky, designed to produce up to 500,000 MMBtu annually and near completion at the time of the latest disclosures, with a second project at the Oneida-Herkimer Regional Landfill in Boonville, New York, acquired in September 2025 and still under development.

The company's technology stack is a conventional four-stage RNG value chain: gas collection from landfill wells, processing to pipeline-quality methane, transportation logistics, and downstream dispensing to end customers. No proprietary patents, software, or AI/ML components are disclosed; the company's stated differentiators are its end-to-end integration capability, faster construction timelines, and the development expertise of its leadership. The leadership team is drawn from the broader RNG and industrial gas sectors — most notably co-founder Casey Holsapple, who previously built Kinetrex Energy's RNG franchise prior to its acquisition by Kinder Morgan in 2021, and CEO Claus Nussgruber, appointed in May 2026 after 30+ years at Air Products, Linde Group, and Utility Global.

Redtail's business model is a project-developer model, generating revenue from RNG volume sales under long-term offtake agreements and from the sale of environmental attribute credits (notably D3 RINs). The company is privately backed by Inyarek Partners, a Boston-based private equity firm, which provided the founding equity commitment in May 2023. In September 2025, Redtail formed joint venture RPM Holdings with Pacolet Milliken, a private investment firm with an existing landfill gas portfolio, to acquire and develop RNG projects across North America — RPM Holdings is the vehicle through which the Owensboro and Oneida-Herkimer projects were acquired. The company does not disclose consumer pricing, production volumes, or revenue figures.

Direct peers

• Vanguard Renewables: Food waste and agricultural digester-to-RNG developer serving commercial and industrial decarbonization customers. Similar B2B offtake model and reliance on voluntary and compliance environmental attribute markets.
• Archaea Energy: Landfill gas-to-RNG developer acquired by bp in 2022. Archaea's focus on upgrading landfill gas into pipeline-quality RNG and selling environmental attributes directly mirrors Redtail's end-to-end value chain.
• Kinetrex Energy: Indianapolis-based RNG and LNG supplier acquired by Kinder Morgan in 2021. Redtail's co-founder Casey Holsapple previously led this platform, making it the closest operational and cultural comparable for Redtail's RNG business model.
• Montauk Renewables: Publicly traded RNG producer (NASDAQ: MNTK) developing biogas-to-RNG facilities from landfill and agricultural waste. Comparable end-to-end development model and reliance on RIN revenue.
• Aria Energy: Landfill gas-to-energy operator that historically focused on electricity and has expanded into RNG. Directly comparable landfill gas capture and upgrading infrastructure.

Emerging players

• Bioenergy DevCo: Anaerobic digestion developer producing biogas/RNG from food and organic waste. Comparable project-development model and offtake to logistics and industrial customers.
• Brightmark RNG Holdings: RNG developer building anaerobic digestion and landfill gas projects across the U.S. Comparable feedstock base and B2B RNG offtake strategy, though at a different scale and with mixed outcomes.
• Gas Recovery Services: Landfill gas collection and utilization operator focused on smaller and mid-sized landfills. Provides feedstock-side infrastructure relevant to Redtail's upstream gas collection operations.

Broad incumbents

• Kinder Morgan: Large midstream energy operator that owns the Kinetrex RNG platform (Redtail founder's prior company). Represents the strategic acquirer profile relevant to Redtail's eventual exit path.
• DTE Biomass Energy: Subsidiary of DTE Energy operating landfill gas-to-energy projects. Comparable landfill gas capture operations, though embedded within a larger regulated utility platform.
