In a study published in the Environmental Research Letters and presented at the United Nations Climate Change Conference (COP28), a photolytic system called Methane Elimination Photolytic System (MEPS) has been developed to eliminate low-concentration methane in the air using light and chlorine. This system boasts a 58% removal efficiency and a flow capacity of 30 L/min, capable of mitigating greenhouse gases from animal shelters, biogas production, and wastewater treatment facilities.

Resembling a metallic box, this reaction chamber facilitates a series of chain reactions utilizing light and chlorine, enabling methane to be broken down approximately 100 million times faster than its natural degradation in the environment.
