Cowboy Clean Fuels, a Wyoming-based climate-tech company, has completed its first sale of durable carbon removal credits through Milkywire, with support from Salesforce's commitment to purchase $100 million in durable carbon removal by 2030. The credits come from the company's biomass carbon removal and storage (BiCRS) pathway in the Powder River Basin, where agricultural residues are injected into depleted coalbed methane reservoirs, generating renewable natural gas and permanently storing CO2 on coal surfaces. The project is certified under the Absolute Carbon Standard and listed on the C-Capsule registry, with independent assessment by Climate Vault Solutions. The sale marks Cowboy Clean Fuels' entry into the CDR market, alongside its existing RNG business. The company says the pathway offers durable geologic storage, renewable gas production, and a large resource base. Buyers can purchase verified credits on-registry, and the company is developing additional projects in the region. This deal highlights the growing demand for durable carbon removal from corporate buyers and the role of legacy energy infrastructure in enabling low-carbon solutions.

Interesting to see a BiCRS project get its first CDR sale. Combining RNG production with permanent storage on coal is a neat way to use legacy infrastructure. Question is how the carbon accounting holds up over time. Worth reading for anyone tracking durable removal deals.

The claim about permanence over 100 years needs scrutiny. Coal seams can have fractures and microbial activity is hard to model. I'd want to see independent monitoring data before treating these credits as permanent. Also, how does the RNG sale affect the net removal math?

Salesforce's $100M pledge is driving early demand. But the real test is whether these credits pass integrity standards like the Integrity Council's or CORSIA. The fact they use Absolute Carbon Standard and C-Capsule registry is a start, but third-party validation is key. Also, the biomass source matters for additionality.

Using coalbed methane wells for storage is clever, but what about the well integrity over decades? And the biomass supply chain from agricultural residues might have emissions from transport. Also, the economic diversification angle for Campbell County is good, but job numbers are vague.

This is a reminder that carbon removal isn't just direct air capture. BiCRS could be a cheaper path if it works at scale. The fact they're using existing infrastructure helps. But the market is young, and the volume is small. Watch for how they scale and if the verification holds.
