Process concepts and analysis for co-removing methane and carbon dioxide from the atmosphere.

ABSTRACT: Methane is the second largest contributor to global warming after CO₂, and it is hard to abate due to its low concentration in the emission sources and in the atmosphere. However, removing methane from the atmosphere will accelerate achieving net-zero targets, since its global warming potential is 28 over a 100-year period. This work presents first-of-its-kind process concepts for co-removal of methane and CO₂ that combines the catalytic conversion of methane step (thermal/photo-catalytic) with CO₂ capture. Proposed processes have been analyzed for streams with lean methane concentrations, which are non-fossil emissions originating in the agricultural sector or natural emissions from wetlands. If the proposed processes can overcome challenges in catalyst/ma
