Cowboy Clean Fuels (CCF), a Denver-based company specializing in renewable energy and CO2 technology, has released a new methodology that combines Biomass Carbon Removal and Storage (BiCRS) with Renewable Natural Gas (RNG).
The novel BiCRS+RNG methodology was developed in a collaborative effort with EcoEngineers, a clean energy consulting, auditing, and advisory company recently acquired by leading global assurance partner LRQA.
As part of the collaboration, Eco made sure that the BiCRS+RNG methodology follows the highest scientific rigor, sustainability, and transparency standards, assuring project developers that by adopting this methodology, they will be in compliance with ISO 14064-2:2019.
What the methodology specifically provides is an innovative, industry-first framework that outlines a strict approach for measuring and monitoring, reporting, and verifying (MRV) an innovative decarbonization technology that brings together biogenic methane production with permanent geologic carbon sequestration utilizing legacy energy infrastructure.
BiCRS represents a technology in which carbon-rich biomass is stored underground, keeping it from decomposing and releasing CO2 back into the atmosphere.
Springing from a proprietary CCF process, the BiCRS+RNG methodology lays out an approach for injecting biomass-derived feedstocks into geologic formations, where it triggers the microbial conversion to carbon and biomethane.
This process also enables the surface production of biomethane, which can then be delivered to end users as a low-carbon renewable natural gas (RNG).
Through a durable adsorption process, this approach offers a pathway for permanent geologic CO2 sequestration that presents a long-term, scalable carbon solution.
By aligning carbon removal projects with the highest industry standards, the BiCRS+RNG methodology developed by CCF provides a verifiable pathway for generating high-integrity carbon removal credits, presenting a market gateway for project developers.
Ryan Waddington, chairman and CEO of Cowboy Clean Fuels, said that the completion of the BiCRS+RNG methodology “represents a major milestone in the evolution of engineered carbon removal and renewable energy production.”
He added, “This methodology enables shovel-ready projects to move forward with confidence, allowing our capital partners to invest with certainty in the Powder River Basin and beyond.”
