Quest Carbon Capture And Storage

The Quest carbon capture and storage (CCS) facility, near Edmonton, Alberta, shows that large-scale CO2 capture is a safe and effective measure to reduce CO2 emissions from industrial sources. Quest was built ahead of schedule and under budget. Since opening in late 2015, the facility has captured more CO2 than expected and stored it safely 2 km underground. Learn more about how CO2 is captured and stored safely.

To date, Quest has captured and stored over 5 million tonnes of CO2. See more here: Quest Reaches Major Milestone.

Shell is sharing the knowledge and lessons learned from building Quest to encourage more widespread implementation of CCS. Detailed information about Quest CCS design and operation can be found on the Government of Alberta website. We are helping to develop other large-scale commercial CCS projects globally and have research partnerships with industry and leading academic institutes.

The Quest facility is operated by Shell on behalf of the Athabasca Oil Sands Project.

Global demand for energy is increasing and the challenge is to meet this demand

0:04

while reducing our carbon footprint. Part of Shell’s solution involves carbon

0:08

capture and storage and that's why we built and operate Quest at the Scotford upgrader. The

0:13

upgrader turns thick heavy oil from the oil sands called bitumen into synthetic crude

0:17

that can then be refined into everyday products like gasoline and jet fuel. Shell

0:22

uses hydrogen to upgrade the bitumen to a lighter oil but making hydrogen

0:25

creates carbon dioxide or CO2 Quest captures the CO2 from the upgrader’s

0:31

hydrogen manufacturing plants with a product called Amine that absorbs CO2. The CO2

0:37

is then separated from the Amine and pressurized to turn the CO2 gas into a

0:41

liquid that can be transported by pipeline 65 kilometers north through well sites.

0:46

At the wells the liquid CO2 is injected more than two kilometres

0:50

underground into a layer of rock filled with interconnected pores. The CO2

0:55

becomes trapped within the pores and locked in under many layers of solid

0:59

watertight rock. Constant monitoring both above and below ground makes sure the CO2

1:04

stays safely and permanently in place. Quest is on track to capture and store

1:09

over one million tonnes of CO2 every year. That's equivalent to the emissions

1:13

from about two hundred and fifty thousand cars. We know that up here

1:18

carbon dioxide is a big problem but we believe deep down there lies an

1:22

important part of the solution.

CCS Facility Exceeding Expectations

In its first operating year, Quest has captured and safely stored one million tonnes of CO2, and has achieved this milestone ahead of schedule.
