U of A researchers are helping make carbon capture more efficient, screening 120,000 carbon capturing solids in hours—instead of thousands of years.
University of Alberta researchers have developed techniques that save a significant amount of time in developing more efficient carbon capture technologies, which may help lower the costs to use the technologies and increase their adoption as a way to mitigate carbon dioxide emissions.
U of A engineering professor Arvind Rajendran and his team developed a two-step screening process that assesses carbon capture materials called zeolites in seconds rather than a day.
Zeolites work by adsorbing—basically sticking to—carbon dioxide molecules, similar to the way odours can be captured by charcoal filters in our refrigerators. In carbon capture systems, the “flue-gas” exhaust emitted from a power plant can be passed through the zeolites, trapping the CO2 before it enters the atmosphere. Theoretically, millions of different types o...
