Shell marked the official opening of the Quest carbon capture and storage (CCS) project in Alberta, Canada, and the start of commercial operations there. Quest is designed to capture and safely store more than one million tonnes of CO2 each year—equal to the emissions from about 250,000 cars. Quest was made possible through strong collaboration between the public and private sectors aimed at advancing CCS globally.
Using activated amine (ADIP-X), Quest will capture one-third of the CO2 emissions from Shell’s Scotford Upgrader, which turns oil sands bitumen into synthetic crude that can be refined into fuel and other products. The CO2 is a byproduct of the production of hydrogen, which is used to upgrade the bitumen.
The CO2 is then transported through a 65-kilometer pipeline and injected more than two kilometers underground below multiple layers of impermeable rock formations. . . .
