“While not a silver bullet … if applied on a massive scale, it could offer the potential for significant removal of carbon dioxide from the air that was emitted in the past.” “Direct-air-capture technology has captured the attention of the public, scientists and engineers, and policy makers in the last year,” said Christopher Jones, a professor of chemical engineering at the Georgia Institute of Technology who is not affiliated with either of the Canadian teams. The new developments coincide with a growing enthusiasm for direct air capture as a viable route to reducing greenhouse gas emissions, in part because of the success of a small pilot plant in Squamish, B.C., operated by the Canadian company, Carbon Engineering Ltd. Results from a second team, based at the University of British Columbia, have been accepted for publication in the journal Joule next month. “The really cool point of this is that it combines existing technologies in a way that bypasses some energy-intensive steps,” said Yuguang Li, a post-doctoral researcher at the University of Toronto who co-led one of the efforts, which published its finding Wednesday in the journal American Chemical Society Letters. But if they can be scaled to commercial size they could significantly improve the efficiency and economics of the direct-air-capture process. While direct air capture has been shown to work at industrial scale, the new experiments featuring the shortcut have only been demonstrated in the laboratory. The shortcut applies to the process known as direct air capture, which aims to harvest and concentrate atmospheric carbon dioxide so that it can be used to generate renewable fuels, plastics or other products that would otherwise be derived from crude oil.
