New device captures carbon dioxide by pumping it across a battery
Summary
Ars Technica covers a lab-scale battery-based approach to capturing CO2, demonstrated by a team led by James Buchen of the University of Delaware. The device uses nickel hydroxide electrodes and a reversible electrochemical cycle to move CO2 across a cell, potentially reducing energy use versus traditional sorption systems. The study also outlines economic feasibility and pilot-scale cost projections, with RepAir Carbon exploring commercialization and Nature Energy publishing the findings.
