Approach shows promise as way to capture CO2 in a more energy efficient manner

Researchers have developed a method that doubles the amount of carbon dioxide that can be captured with a supercapacitor. The devices made from coconut shell-derived porous carbon, capture CO­2 as they charge, which can then be controllably released when discharging the capacitors for collection and storage. By altering the voltage applied to the supercapacitor device while it’s charging, the scientists are able to significantly increase the carbon capture performance.
