Shell’s Quest CSS facility reaches CO2 capture milestone

Published by
Oilfield Technology,

The Quest carbon capture and storage (CCS) facility has captured and safely stored 4 million t of CO2, ahead of schedule and at a lower cost than anticipated.

Quest is world’s first commercial-scale CCS facility applied to oil sands operations and is operated by Shell on behalf of the Athabasca Oil Sands Project (AOSP).

The Quest CCS facility captures and stores about one third of the CO2 emissions from the Shell operated Scotford Upgrader near Fort Saskatchewan, Alberta, which turns oil sands bitumen into synthetic crude that can be refined into fuel and other products. The CO2 is transported through a 65km pipeline and injected more than two km underground below multiple layers of impermeable rock formations.

4 million t of CO2 is about equal to the annual emissions of one million cars. Quest has now stored underground the most CO2of any onshore CCS facility in the world with dedicated geological storage.

“Quest continues to show the world that carbon capture and storage (CCS) is working, its costs are coming down,” said Michael Crothers, Shell Canada President and Country Chair. “If Quest were to be built today, we estimate it would cost about 20-30% less to construct and operate.”
