A research team from the University of Toronto has developed a new electrochemical path to transform CO2 into valuable products such as jet fuel or plastics. The technology could significantly improve the economics of capturing and recycling carbon directly from the air.
“Today, it is technically possible to capture CO2 from air and, through a number of steps, convert it to commercial products,” says University Professor Ted Sargent, in the Edward S. Rogers department of electrical and computer engineering, who led the research team.
“The challenge is that it takes a lot of energy to do so, which raises the cost and lowers the incentive. Our strategy increases the overall energy efficiency by avoiding some of the more energy-intensive losses.”
Direct-air carbon capture is an emerging technology in which companies aim to produce fuels or plastics from carbon that is already in the atmosphere, rather than from fossil fuels. Canada’s Carbon Engineering, which has built a pilot plant in Squamish, B.C., captures CO2 by forcing air through an alkaline liquid solution. The CO2 dissolves in the liquid, forming a substance called carbonate.
