Cowboy Clean Fuels

Cowboy Clean Fuels (CCF) is a Denver, Colorado climate-technology company, founded in 2020 and operating in Gillette, Wyoming, that produces carbon-negative renewable natural gas (RNG) while permanently sequestering atmospheric carbon dioxide. CCF injects non-food-grade organic biomass — residue products of sugar-beet refining such as molasses — into depleted coal bed methane (CBM) wells in the Powder River Basin, where naturally occurring methanogenic microorganisms convert the feedstock into methane and carbon dioxide; the coal seam then selectively adsorbs and permanently stores the CO2. Its lead development is the Triangle Unit Renewable Energy and Carbon Capture and Storage Project (TRECCS) near Gillette, Wyoming, and in May 2025 it signed an offtake agreement with Mercuria for RNG produced under its BiCRS+RNG methodology. Cowboy Clean Fuels is an energy and carbon-dioxide-removal operator, not a software vendor: it sells molecules and carbon removal credits, and publishes no developer program, public API, SDK or machine-readable specification.

Cowboy Clean Fuels is profiled on the APIs.io network. Tagged areas include Company, Energy, Renewable Natural Gas, Carbon Removal, and Carbon Sequestration.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.

  detail: Every path on cowboycleanfuels.com — homepage, /llms.txt, /robots.txt, /sitemap.xml and all nine /.well-known/ probes
    — answered HTTP 202 with a SiteGround "sgcaptcha" meta-refresh interstitial instead of a document, and the www vhost is
    a legacy Squarespace host that 301s everything back to that apex, so not one page of the provider's own site could be
    read without evading the challenge.
