PERMA Full-Scale Methane Eradication Photochemical System (MEPS)
The Department of Chemistry, University of Copenhagen is pleased to announce the start of the PERMA Full-Scale Methane Eradication Photochemical System (MEPS) project.
The Department of Chemistry, University of Copenhagen is pleased to announce the start of the PERMA Full-Scale Methane Eradication Photochemical System (MEPS) project.
PERMA is a collaborative research and innovation project involving the University of Copenhagen, Aarhus University, Ambient Carbon, and Arla Foods, with a total project budget of 21 million DKK. The project is led by Matthew S. Johnson, Professor of Atmospheric Chemistry at the Department of Chemistry.
The project builds on a photochemical methane-removal technology invented at the Department of Chemistry and is being further developed and implemented by the University of Copenhagen spin-out company Ambient Carbon, which serves as the technology provider for the project.
The PERMA Full-Scale MEPS project will:
Design, build, and operate a full-scale MEPS unit integrated with barn air extraction and control systems at a 100-cow dairy barn.
Demonstrate 75–90% removal of methane, ammonia, and odor, with low energy consumption and fully auditable measurement, reporting, and verification (MRV) data.
Deliver a certified, scalable Danish mitigation solution enabling low-methane milk production by 2028, targeting Technology Readiness Level (TRL) 8–9, with clear pathways to deployment in Europe and North America.
The project represents a significant step toward practical, verifiable mitigation of agricultural methane emissions using advanced photochemical technologies developed in Denmark.
