CO2 scrubbers have been developed but so far, all have been prohibitively expensive. The Journal of the American Chemical Society reports that researchers at the University of Southern California’s Loker Hydrocarbon Research Institute have developed an extraction method that has achieved some of the highest rates ever reported for removing carbon dioxide from the air. The method, which is low-cost and simple, involves use of a plastic-like substance dispersed in a sandy material called fumed silica. The technique allows the carbon dioxide to be used for recycling or to be isolated from the environment.
One the study’s researchers claims fumed silica is cheap to produce and can be used multiple times without losing efficiency. They claim the technique is more energy efficient and more chemically stable than existing extraction devices. The technique is expected to be released in the next 3 to 5 years.
