A new carbon capture and storage project capable of removing emissions equal to those of 250,000 cars has been opened in Canada by energy firm Shell.
The Quest CCS project in Alberta will capture about one third of 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 will subsequently be transported through a 65-kilometre pipeline and injected more than two km underground below multiple layers of impermeable rock formations.
The project, capable of storing more than 200,000 tonnes of CO2, has been extensively tested earlier this year and has now started commercial scale operations.
"Quest represents a significant milestone in the successful design, construction and use of carbon capture and storage (CCS) technology on a commercial scale,” said Shell's Chief Executive Officer Ben van Beurden.
“Quest is a blueprint for future CCS projects globally. Together with government and joint-venture partners, we are sharing the know-how to help make CCS technologies more accessible and cost-effective for the energy industry and other key industrial sectors of the economy."
Built jointly by Shell Canada Energy, Chevron Canada Limited and Marathon Oil Canada Corporation, the Quest project relies on techniques used by the energy industry for decades and integrates the components of CCS for the large-scale capture, transport and storage.
CCS is one of the only technologies that can significantly reduce carbon emissions from industry sources. The technology can be applied to reduce CO2 emissions across a wide range of sectors including power generation, cement, chemicals and refining, iron and steel and upgraders.
