World's Largest Capacity CO2 Pipeline Operational

Written by Darrell Peterson, Thomas McInerney, Patrick Maguire and Keely Cameron

The Success

On June 2, 2020, the $1.2 billion Alberta Carbon Trunk Line (ACTL) became operational. The ACTL is part of an integrated system designed to capture and store CO₂ emissions, and further the development of a lower carbon economy in Alberta.

What It Means

The ACTL provides increased capacity for transporting CO₂ emissions for storage and is expected to serve as an example for similar projects in the future given the increased focus on addressing CO2 emissions across all sectors of the economy.

The ACTL

This 240 km pipeline will transport liquefied CO₂ from Alberta's industrial heartland area northeast of Edmonton, to an area near Red Deer in central Alberta. Enhance Energy will then sequester the CO₂ in depleted oil reservoirs, storing the CO₂ and enabling additional oil recovery from the reservoir. The ACTL, which is owned and operated by Wolf Midstream, has the capacity to transport 14.6 million tonnes of CO₂ per year and is currently the largest pipeline of its kind in the world. The North West Redwater refinery and the Nutrien Redwater Fertilizer facility, are the first to use the pipeline, transporting up to 1.8 million tonnes of CO₂ per year. The ability to capture and sequester CO₂ is a fundamental component of the North West Redwater refinery, allowing it to be one of the lowest CO₂ emissions refineries in the world. The ACTL's additional capacity will allow more producers and reservoirs to be added in the future.

This is not the first carbon capture and storage facility in Alberta. The first was Shell Canada's Energy Quest at the Scotford Upgrader, also located near Edmonton which commenced operations in 2015. In 2019, Shell announced that the project captured and stored four million tonnes of carbon dioxide ahead of schedule and at a lower cost than anticipated.

The path to ACTL becoming fully operational has been a long one, with the project originally conceived by Enhance Energy in 2009. Despite initial funding by the federal government and the province of Alberta, the ACTL was not fully financed until 2018, with construction commencing shortly thereafter. Additional projects linking the ACTL to the oilsands near Fort McMurray are now being considered.
