The Quest CCS Project, operated by Shell Canada in partnership with Chevron Canada and Canadian Natural Resources Limited, is located near Fort Saskatchewan, Alberta. Commissioned in 2015, Quest captures about 1 million tonnes of CO₂ per year from the Scotford Upgrader’s hydrogen production units, where CO₂ is separated during steam methane reforming. The captured CO₂ is compressed and transported through a 65-kilometer pipeline to an injection site north of Edmonton, where it is stored in the Basal Cambrian Sandstone, a deep saline aquifer more than 2 kilometers underground. Quest has safely stored over 7 million tonnes of CO₂ to date, with extensive monitoring and verification using seismic imaging, pressure monitoring, soil gas surveys, and groundwater sampling. The project was the first commercial-scale CCS facility for oil sands operations, and it continues to serve as a global reference for integrated CCS design and regulatory transparency. Performance data and lessons learned from Quest are publicly shared, contributing to the advancement of future large-scale CCS projects in Canada and worldwide. Vault has withdrawn this project to the EPA in late 2025.
