Scientists invent "methane cleaner" to tackle harmful livestock emissions

Researchers at the University of Copenhagen have made a breakthrough in tackling methane emissions from cattle and other sources. They've developed a unique method, dubbed the "methane cleaner," that uses light and chlorine to remove this potent greenhouse gas from air.
Why is this important? Methane is a major contributor to climate change, up to 85 times more powerful than CO2. Over half of human-caused methane comes from sources like cattle and pig farms, biogas plants, and wastewater treatment facilities. Traditionally, these low-concentration emissions are difficult to handle.
How does the cleaner work? The researchers built a reaction chamber that resembles a metal box with hoses and instruments. Inside, a chain reaction triggered by light and chlorine breaks down methane molecules, removing a significant portion from the air. They've achieved an impressive 88% removal rate in the lab so far.
Benefits beyond the lab:
Livestock farms: The researchers envision connecting the methane cleaner to existing air purification systems in cattle stalls, similar to how ammonia is already removed.
Biogas and wastewater plants: These facilities also leak substantial methane, and the cleaner could capture these emissions, improving Denmark's biogas production efficiency.
Faster than nature: The reaction in the chamber happens 100 million times faster than the natural breakdown process, making it a powerful tool for reducing methane pollution.
Next steps: A larger prototype of the chamber is arriving soon, paving the way for real-world applications. The researchers are optimistic that their invention can significantly contribute to climate change mitigation efforts.

This research holds exciting potential for reducing harmful methane emissions from various sources. By bringing the "methane cleaner" to farms, treatment plants, and beyond, we can take a big step towards a cleaner and greener future.

        Very interesting innovation. But chlorine is harmful to human health. How do you resolve this problem producing these reactors on a bigger scale?

          Thank you so much for the climate love! It is great to see our work on We Don't Have Time and to read the positive feedback. We are working hard in the laboratory to further improve MEPS. We're looking forward to doing a trial at the Doerr School of Sustainability at Stanford in March in order to test a wide range of pollution conditions. We are also making our system portable so we can take it into the field and remove methane from an agricultural research station. And we received the largest Christmas package ever -- a full sized shipping container! We're putting MEPS into the container and will be taking it to wastewater treatment plants, farms and biogas facilities later in 2024.
