David Keith, a scientist at the University of Calgary, and his team have developed a technology to efficiently capture carbon dioxide directly from the air. This new technology could be very helpful in capturing emissions for automobiles and airplanes. Keith, who is also the Canada Research Chair in Energy and Environment, said, “At first thought, capturing CO2 from the air where it’s at a concentration of 0.04 per cent seems absurd, when we are just starting to do cost-effective capture at power plants where CO2 produced is at a concentration of more than 10 per cent.” The University of Calgary, though, reports that Keith and his team showed they could capture CO2 directly from the air with less than 100 kilowatt-hours of electricity per ton of carbon dioxide.
