– Methane mitigation from an underground coal mine with the VAMOX® technology for the generation of carbon credits.
Methane emitted through underground coal mine ventilation air, known as Ventilation Air Methane (VAM) is a potent greenhouse gas (GHG) having a global warming potential 25 times more powerful than CO2. Global VAM emissions are estimated to contribute close to 700 million tonnes of carbon dioxide equivalent (MtCO2e) annually. Based on the experience of its first VAM abatement project carried in Alabama from 2009 to 2013, Biothermica has completed the design of a Second-generation Vamox® Regenerative Thermal Oxidizer (RTO) system fully optimized to mitigate VAM emissions, and will be implementing its technology at one of the largest underground metallurgical coal mine in the United States in 2019. This $ 15-million project will be the largest of its kind in America and will lead to the mitigation of 530,000 tCO2e per year. It will be financed through the sale of carbon offsets on the Québec-California regulated market.
