Dairy Barn Methane Levels and Feasibility of Thermal Catalytic Oxidation for Net Climate Benefit.

ABSTRACT: Thermal catalytic oxidation has emerged as a promising technique to destroy methane from dilute sources, such as agricultural emissions in engineered indoor environments. The concentration of methane and total volumetric treatment requirements must be understood to evaluate the feasibility of this approach, particularly with respect to economic and environmental viability. Here, dairy farm field sampling campaigns were conducted in New England dairies (free stalls with 600-1,200 head of cattle in both convection and tunnel ventilation) to establish a robust framework to evaluate the climate-benefits and cost-effectiveness associated with deployment of thermal catalytic methane oxidizers in these housing styles. Methane (CH₄) levels ranged from 2-70 ppm in summer and 2-102 ppm in
