Shell QUEST project captures and stores 4m tonnes of CO2

摘要

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 65-kilometre pipeline and injected more than two kilometres underground below multiple layers of impermeable rock formations.Since its start up in late 2015, the capture process at Quest has also worked better than anticipated, helping the facility exceed its target of capturing one million tonnes of CO2 per year.The facility is also safely storing the CO2 deep underground better than expected.The geological formation used for storage, which is prevalent across much of Western Canada, is demonstrating incredible capacity for CO2 injection.Quest has a robust measurement, monitoring and verification program verified by a third party(Det Norske Veritas(DNV))to ensure the CO2 is permanendy stored.”Quest continues to show the world that carbon capture and storage(CCS)is working, its costs are coming down and that Canadians are leaders in CCS,”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.With our know-how, strong regulatory frameworks and ideal geology, Canada is uniquely positioned to capitalize on CCS technology.”
