Researchers develop battery-based electrochemical method to capture carbon dioxide from the air
A research team led by James Buchen at the University of Delaware has demonstrated a new electrochemical technique for carbon capture. The method uses a battery-like system to pull carbon dioxide from the environment, potentially offering a more energy-efficient and cost-effective alternative to existing filtration technologies.
Traditional carbon capture methods typically rely on reversible filters, where air passes through liquids or granules that absorb CO2 before being heated to release the gas. According to Ars Technica, a new study from the University of Ser Delaware suggests a different approach using a battery-based system.
The process works by using a battery cathode to produce hydroxide, which reacts with CO2 to create carbonate or bicarbonate. This substance moves through a separator membrane to the anode, where a lower pH level reverses the reaction, releasing the CO2 as gas. The researchers claim this electrochemical technique could be more viable than current designs because it may require less energy, which could lead to lower operational costs.
