Shellhas begun carbon capture and storage (CCS) operations at its Scotford Upgrader,in Alberta, Canada. The project is intended totrap and store over one million metric tons of carbon dioxide (CO2) annually.

Theproject, dubbed "Quest," is one of the world's first large-scale CCSprojects to reduce emissions from oil sands processing. The launch followssuccessful testing earlier this year at the site, during which the processcaptured and stored more than 200,000 tons of CO2.

Questis designed to capture one-third of the emissions from the site, which turnsoil sands bitumen into synthetic crude. The CO2 is then transported through a65-kilometer-long pipeline and injected more than 2 km underground (see videohere).

TheAthabasca Oil Sands Project joint-venture owners—Shell Canada Energy (60%),Chevron Canada Limited (20%) and Marathon Oil Canada Corp. (20%)—received C$865million ($651 million) in funding for Quest from the governments of Alberta and Canada. As part of the fundingarrangements, Shell is publicly sharing information on Quest's design andprocesses to help advance global adoption of CCS.

Shelland the U.S. Department of Energy also plan to collaborate on field tests tovalidate advanced monitoring technologies for underground storage of CO2. Thetechnologies under consideration will be tested alongside the monitoringprogram already in place for Quest.

TheInternational Energy Agency (IEA) says that CCS will play a key role inminimizing climate change and can account for one-sixth of required emissionsreductions by 2050. According to IEA analysis, without significant deploymentof CCS, more than two-thirds of current proven fossil-fuel reserves cannot becommercialized before 2050 if the increase in global temperatures is to remainbelow 2 degrees Celsius.
