Battery-like device pulls CO₂ from air using electricity and saltwater chemistry

Researchers have developed an electrochemical device that mimics a battery to extract carbon dioxide directly from ambient air. The system uses electricity and saltwater chemistry to convert CO₂ into stable carbonate minerals, offering a potential new method for direct air capture (DAC). Coverage highlights its novelty in combining energy storage principles with carbon removal, positioning it as a scalable alternative to existing DAC technologies.

Coverage from *Journal Gazette & Times-Courier*, *Bioengineer.org*, *Scientific Frontline*, and *Tech Xplore* emphasizes the device’s dual functionality—acting as both an energy storage system and a carbon capture mechanism. Early reports focus on its theoretical efficiency and the potential to integrate with renewable energy grids. No operational deployment or performance metrics have been released.

Next steps will likely involve lab-scale validation, energy efficiency assessments, and comparisons to existing DAC methods. If scaled, the technology could influence climate mitigation strategies by offering a more flexible, electricity-driven approach to carbon removal.
