Aquistore Project

Diagram of geology present at the Aquistore Project.

The Aquistore Project, managed by the Petroleum Technology Research Centre (PTRC), is designed to inject CO2 from human activity into a sandstone layer
3400 meters (11,000 feet) below ground. The source for the CO2 is the SaskPower Boundary Dam Carbon Capture Project—the first-ever commercial-scale capture of CO2 from a coal-fired power plant. Aquistore receives a portion of the CO2 captured by the Boundary Dam Project, but a larger percentage is sent to the nearby Weyburn oil field for enhanced oil recovery. Boundary Dam’s incorporation of Aquistore, however, represents the first project in Canada to demonstrate a complete system for the capture, transportation, injection, and storage of human-derived CO2 into a formation not associated with oil and gas recovery.

Industrial CO2 is injected and securely stored in a deep saline formation.

Project Objectives

  • Demonstrate that carbon capture and storage (CCS) methods involving CO2 storage in a deep saline water-bearing geologic formation are safe, workable solutions for reducing greenhouse gas emissions.
  • Demonstrate and validate effective technologies for characterizing and monitoring carbon storage in deep saline formations that may be widely applicable.
  • Assist in the development of essential connections
    among industries implementing or considering this technology, policy makers drafting regulations around CCS, financial institutions trying to understand the economic implications of business within a carbon-managed environment, and the public learning about, and living with, the technology.

The Aquistore Project is evaluating monitoring, verifying, and accounting technologies; adapting existing technologies; and pioneering new ones to suit geologic storage of CO2 in deep saltwater-filled rock layers. Along the way, the project has continued to provide data and information critical to assessing the feasibility of long-term CO2 storage in these deep saline formations. As the project matures, it will serve to verify technical and economic components required for commercialization and widespread industry acceptance of CCS.

More than 100,000 tonnes CO2 stored.
In February 2017, the Aquistore project reached a milestone of 100,000 tonnes of CO2 injected into the deep sandstone layer.
