Carbon capture

Basin Electric Power Cooperative is to use Powerspan’s carbon dioxide (CO₂) capture technology to demonstrate its viability at the Antelope Valley Station, a coal-based electric power station located near Beulah, North Dakota.

Approximately one million tons of CO₂ will be captured annually from the 120MW slipstream project, making the demonstration among the largest in the world.

The captured CO₂ will be fed into an existing CO₂ compression and pipeline system owned by Basin Electric’s wholly owned subsidiary, Dakota Gasification.

The project is scheduled to move forward in 2009, subject to the successful completion of engineering studies and obtaining of necessary permits and US government incentives.The facility itself is expected to be operational in 2012.

Powerspan’s CO₂ capture process, called "ECO₂" is a post-combustion, regenerative process which uses an ammonia-based solution that captures CO₂ from the flue gas of a power plant and releases it in a form that is ready for further compression, safe transportation, and geological storage.
