Denmark-based Ambient Carbon is partnering with Benton Group Dairies to test its new methane-eradicating system for cow barns, which it says is a “first-of-a-kind” non-invasive technology to remove methane from dairy barn exhaust. The company will install its Methane Eradication Photochemical System (MEPS) at Benton’s dairy farm in Ambia, Indiana in the US this month in preparation for installing and testing a MEPS field prototype in early 2025.
