Researchers at UW-Madison have developed a way to pull carbon dioxide from the air and store the heat-trapping gas in solid particles that can be turned into building materials.
Now they are looking to scale their laboratory experiment into a business that can solve two of the biggest challenges to fighting climate change.
Known as Earth RepAIR, the project is built on concepts developed by Bu Wang, an assistant professor of civil and environmental engineering, and Rob Anex, a professor of biological systems.
The student-led team is among the finalists in a four-year, $100 million XPRIZE competition designed to spur development of carbon removal technologies. To be eligible for the grand prize the team must build a working plant that can capture 1,000 tons of carbon dioxide per year as well as model the costs at a scale of 1 million tons a year.
