Precision Combustion, Inc. (PCI) is developing a modular catalytic system for methane mitigation from ventilation air methane (VAM) from underground coal mines. It is based on an advanced contaminant-tolerant catalyst design that enables high methane destruction and removal efficiency (DRE) at lower operating temperature. Long term durability and contaminant tolerance were demonstrated at the lab-scale for 1000’s of hours for methane concentrations ranging from <100 ppmv to 1% (by vol.) in air. Performance data from operation with high humidity VAM streams, levelized cost of carbon abatement (LCCA), and life cycle impact findings for methane mitigation from mining operations will be discussed. LCCA analysis showed potential revenue generation via carbon credits. A pilot unit was fabricated and is being tested at a mine site. Initial data will be shared.
