Turning Captured CO2 into Carbon-Negative Nickel

Quick Summary

• Researchers propose injecting carbon dioxide deep underground to turn the gas into minerals, effectively removing it from the atmosphere.
• The process could also extract critical metals, such as nickel, which are essential for clean energy technologies like batteries.
• Quin Miller from Pacific Northwest national Laboratory (PNNL) stated this method allows for targeted mining while retaining unwanted materials underground and retrieving useful ones.
