  "account": "A team led by James Buchen at the University of Delaware has developed a novel carbon capture device that operates by pumping carbon dioxide across a battery. Unlike traditional methods that use granules or liquids to absorb CO2 and then heat it to release the gas, this electrochemical approach relies on chemical reactions within a battery. The design involves producing hydroxide ions at the battery cathode, which react with CO2 to form carbonate or bicarbonate. These compounds then pass through a separator membrane to the anode, where the lower pH causes the reaction to reverse, releasing CO2 gas. The innovation of this battery-based technique is its potential for lower energy consumption, making it a more cost-effective solution compared to existing reversible-filter designs.",
  "summary": "The design requires less energy to capture CO 2 than current systems.",
