Breakthrough Study Reveals Selective Carbon Capture Method Straight from the Air

Scientists at Northwestern University have developed a new carbon capture method called the "moisture-swing" technique, which captures CO2 from the air at low humidities and releases it at high humidities. This innovative approach utilizes a range of ions and offers a more energy-efficient solution compared to traditional carbon capture techniques. The research expands our understanding of direct air carbon capture (DAC) and provides insights into complex fluid-surface interactions. The study demonstrates the potential for carbon removal from virtually anywhere, contributing to the fight against climate change and the need to extract existing atmospheric carbon dioxide.
