A groundbreaking method developed as part of the AgriFoodTure project PERMA has successfully removed methane from the air.
The result gets us closer to being able to remove greenhouse gases from livestock housing, biogas production plants and wastewater treatment plants to benefit the climate.
“A large part of our methane emissions comes from millions of low-concentration point sources like cattle and pig barns. In practice, methane from these sources has been impossible to concentrate into higher levels or remove. But our new result proves that it is possible using the reaction chamber that we have built,” says Professor Matthew Stanley Johnson of Copenhagen University, who leads the research team.
To remove methane from air, the researchers built a reaction chamber that, to the uninitiated, looks like an elongated metal box with heaps of hoses and measuring instruments. Inside the box, a chain reaction of chemical compounds takes place, which ends up breaking down the methane and removing a large portion of the gas from air.
