  "account": "A new study led by James Buchen of the University of Delaware introduces an electrochemical carbon-capture technique that operates within a battery. Unlike previous methods that utilize filters, this innovative approach may prove to be more energy-efficient and cost-effective. The core concept behind this device involves the reaction of hydroxide at the battery's cathode with carbon dioxide, transforming it into carbonate or bicarbonate. This compound then travels through a separator membrane to the battery's anode, where a decrease in pH triggers the reverse reaction, converting the carbonate back into carbon dioxide gas. At the anode, the hydroxide ions are consumed, completing the cycle.",
  "summary": "The design requires less energy to capture CO 2 than current systems.",
