Pipeline Information

Capture and transport

Nearly 12,000 feet of the 205-mile CO2
pipeline was replaced in 2007.The new
section runs beneath Lake Sakakawea.

Transporting carbon dioxide (CO2) from a capture facility to a sequestration site is the easiest part of the CO2 emissions mitigation challenge.

In 1997 Dakota Gas agreed to send 96 percent CO2 from the Synfuels Plant through a 205-mile pipeline to an oilfield near Weyburn, Saskatchewan, Canada. The CO2 is used for enhanced oil recovery.

Groundbreaking for the CO2 pipeline was held in May 1999. 14-inch and 12-inch carbon steel pipe was laid through western North Dakota and southern Saskatchewan.

Since September 2000, Dakota Gas has been successfully capturing a portion of its CO2 emissions and transporting the gas to Canada.

Today, Dakota Gas provides CO2 to one of the largest carbon sequestration projects in the world. With the addition of another CO2 compressor in 2006, pipeline capacity ;increased to 160 MMSCF (8,000 metric tons) each day. Approximately 17 million metric tons of CO2 has been captured since the project began October 2000. The CO2 is expected to be permanently sequestered in the oil reservoir, which is monitored by the International Energy Agency (IEA) Weyburn CO2 Monitoring and Storage Project.
