CCS-project Quest
Shell’s Athabasca Oil Sands Project (AOSP, Shell share 60%) is planning a carbon capture and storage (CCS) project, called Quest, near to its Scotford Upgrader. The total cost of the project is projected to be USD 1.35 billion. The province of Alberta (USD 745 million) and the government of Canada (USD 120 million) are willing to pay most of the costs. The plant is planned to be commissioned at the end of 2015.
The CO2 will be permanently put under the ground during an estimated 25 years at a depth of over 2,000 meters, in a saline formation, with a maximum of 1.2 millions tonnes of CO2 each year. In a recent report quantifying the GHG reduction benefits from the CCS-project, the facilities were assumed to operate with 90% availability, capturing 1.08 million tonnes of CO2 annually. The full lifecycle emissions of the CCS-project itself were estimated to be between 0.16 to 0.24 million tonnes of CO2, around 20% of the annual capture. Conclusively, the project is estimated to reduce 0.84 to 0.92 million tonnes of CO2 annually.109 AOSP emitted 3.7 million tonnes of CO2-equivalents in 2009110, while its production stood at 78,000 barrels per day. Considering an already planned 440,000 barrels per day tonnes of production by AOSP and in- situ by Shell before 2020, the CCS-project will only partly compensate for the increasing emissions due to deriving fuel from oil sands compared to fuels derived from conventional oil. read more
