Researchers at the University of Cambridge developed a method to charge activated charcoal, used in water filters, with ions to capture carbon dioxide directly from the air. This charged material requires lower temperatures to remove the captured CO2 so it can be stored, making it potentially more energy efficient than current carbon capture methods.
