IN JULY 2020, Shell Oil's Alberta-based Quest project announced that, in under five years since it had started operating, it had captured and safely stored five million tonnes of carbon dioxide - an amount equal to the annual emissions from 1.25 million cars. The federal government identifies carbon capture as being critical to six key pathways in its net-zero strategy: decarbonizing heavy industry, developing negative-emissions tech that can scrub CO2 from the atmosphere, producing on-demand low-carbon power, producing low-carbon hydrogen, promoting industries that use CO2 and, most critically, making cleaner oil and gas. CO2 is injected into the oil field, residual oil and gas is recovered at the surface, and then any extra CO2 is reinjected, permanently storing an average of 1.7 Mt per year - over 36 Mt since operations began in 2000. Mechanical carbon capture of any kind basically requires an absorber reactive with CO2 to capture it from air or exhaust, plus a stripper that removes pure CO2 and pipes it off.
