Cowboy Carbon Dioxide Removal (Cowboy CDR) results from Cowboy Clean Fuels’ innovative and patented process defined as Biomass Carbon Removal and Storage plus Renewable Natural Gas (BiCRS+RNG). It works by storing CO2 removed from the atmosphere permanently in geologic formations, while simultaneously producing Renewable Natural Gas. Cowboy Clean Fuels has pioneered this process in the Powder River Basin (PRB) of Wyoming and is commercializing it there and elsewhere around the globe.
Unlike other emerging and conventional Carbon Capture and Storage (CCS) and CDR methods, Cowboy’s BiCRS+RNG process involves the injection of carbon – in the form of solubilized renewable organic materials, such as agricultural processing residues – directly into subsurface, unmineable coal formations, which are home to native microorganisms. These microbes readily digest the carbon-rich materials, producing CO2 and methane in the process. In this way, the coal seams act as “geo-bioreactors,” enabling rapid conversion of the organic feedstock and – due to coal’s strong natural affinity to adsorb CO2 – ensuring the durable and permanent sequestration of carbon deep underground.
