About the project

Cowboy Clean Fuels (CCF) utilizes a proprietary and patented process to generate carbon-negative renewable natural gas (RNG) in commercial quantities. The CCF methodology generates RNG through anaerobic digestion of 100% renewable feedstock (agricultural byproduct) using an in-situ coal seam as a naturally occurring bioreactor with a capacity of ~8 billion cubic feet. Operational infrastructure is repurposed from end-of-life coal bed methane fields. Anaerobic digestion of feedstock produces approximately equal parts CH4 and CO2. Gases generated within the coal are naturally separated and CO2 is adsorbed to the coal and permanently sequestered, making this process more durable than geologic sequestration alone. Methane remains mobile and enters the production stream while CO2 becomes sequestered within the formation due to the adsorption uptake affinity of the target coal seam being 3-5 times greater for CO2 than CH4. RNG is pipeline ready, and distinguishable from fossil CBM through standard test methodology. CCF plans to sequester ~100,000 tons of CO2 annually within the ~12,500-acre CCF operational unit. The vastness of suitable coal seams and available feedstock make this methodology scalable and sustainable. Simultaneous generation of carbon-negative RNG makes it economically and environmentally advantageous.

    CCF methodology produces sustainable renewable natural gas along with the carbon sequestration. The implementation of this technological process has the ability to produce measurable quantities of RNG for the foreseeable future. The size of the reservoir and the potential applications of the technology have the ability to generate substantive volumes of carbon negative RNG to bolster our energy production in a clean and responsible manner. In addition to generation of RNG, the CCF process addresses several key goals outlined by the US Department of Energy:

    • Decreased Environmental Exposure and Burdens: The CCF project repurposes existing fossil infrastructure in the use of shut-in/orphaned CBM wells and infrastructure to inject a food biproduct to feed the archaea existing withing the coal seam to produce biogenic gas. In the process of breaking down the feedstock, equal parts methane and carbon dioxide are created. The coal’s affinity for carbon ensures that the carbon binds to the coal and is sequestered within the coal seam. This project not only repurposes fossil infrastructure but also sequesters carbon.
    • Increased Parity in Clean Energy Technology Access and Adoption: The project is unique in its ability to bridge the gap between traditional natural gas development and renewable natural gas. This project uses traditional CBM infrastructure but with a technological process that creates RNG in the form of pure biogenic methane. The bridge that this creates is unique in its ability to garner support of clean energy because of the technology’s similarities to traditional natural gas production but with a carbon negative footprint.
    • Increased Clean Energy Jobs: The CCF project will result in carbon negative gas but employ workers similar to traditional natural gas producers. Currently there are 11 full time employees at CCF and as this project develops additional jobs will be added both as direct hires and through support functions.
    • Increased Energy Resiliency: The implementation of this technological process has the ability to produce measurable quantities of RNG for the foreseeable future. The size of the reservior and the potential applications of the technology have the ability to generate substantive volumes of carbon negative RNG to bolster our energy production in a clean and responsible manner.

    To date, Cowboy Clean Fuels has received assessments by the following agencies:

    Wyoming Oil and Gas Conservation Commission: The WOGCC has provided CCF with an operator number and the company is in good standing with the agency.

    Wyoming Department of Environmental Quality: The WYDEQ has reviewed CCFs Underground Injection Control (UIC) permit application. The agency has issued a draft permit based on information received.

    United States Environmental Protection Agency: The US EPA is currently evaluating the CCF methodology as it related to the generation of RNG. The US EPA will be conducting a Lice Cycle Assessment of the full process and will be generating a pathway for CCF to obtain a renewable identification number.

    United States Department of the Interior: CCF is engaged with the DOI through the Bureau of Land Management (BLM). The BLM acts as the regulating body for activity related to operations on federal land and with federal minerals. The BLM has provided input to CCF and the company is in good standing with the BLM.

    Puro.Earth: Puro.Earth has reviewed and assessed the entire CCF process and has certified the company as a carbon removal supplier with geologic sequestration.

    Modern West Advisory: ModWest is an environmental and engineering consulting firm based in Calgary, Alberta, Canada. They have produced an initial Life Cycle Assessment of the CCF methodology in its entirety. Their assessment of the process results in a negative carbon intensity score.
