The XPRIZE for Carbon Removal Student Competition recently announced $5 million in awards for student teams. The Madison team is getting the largest possible award for the student competition for its work to pull carbon dioxide out of the air, reducing the environmental impact of this greenhouse gas.

Their system uses a “direct air capture” unit to trap C02 and a carbonization mechanism for converting the gas into solid particles that can be repurposed for other uses.

“We are really excited about our technology, and it’s cool to be working on something that has the potential of scaling up in a big way and actually have an impact,” says team leader Keerthana Sreenivasan, a graduate student in civil and environmental engineering.
