Powerspan Setup Post Combustion CO2 Capture Demonstration Project In N Dakota
Basin Electric Power Cooperative and Powerspan have announced the selection of Powerspan's carbon dioxide (CO2) capture technology for a commercial demonstration at Basin Electric's coal-based electrical generation facility, the Antelope Valley Station located near Beulah, North Dakota. Approximately one million tons of CO2 will be captured annually from the 120 megawatt slipstream project, making this 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 Company.
"The greatest reductions in CO2 emissions from the power sector can be achieved by developing and proving a technology that can be retrofitted to the hundreds of existing coal-based power plants in the U.S. This is an important first step to achieving that goal."
Basin Electric's wholly owned subsidiary, Dakota Gasification Company, is the only company in the U.S. that captures CO2 from coal and delivers it for enhanced oil recovery operations. In 2000 Dakota Gasification began delivering carbon dioxide from its coal gasification facility, the Great Plains Synfuels Plant, to oil producers in Saskatchewan, Canada. With over seven years experience in capturing and sequestering CO2, Basin Electric is well prepared to move this demonstration project forward.

Swedish Firm Set Up Pilot CCS Project In Germany - CNN
Located at Vattenfall's Schwarze Pumpe power station in Brandenburg, the pilot project will utilize oxyfuel combustion technology.
The Oxyfuel combustion process first separates nitrogen -- which makes up about 78 percent of air -- from the atmosphere allowing coal to be burnt with pure oxygen in a boiler. The steam powered turbines provide power in the usual way, but separating the CO2 from the flue gases is far easier.
Once small particles and sulphur have been removed the flue gas is then cooled allowing the water to condense leaving near pure CO2, which is then compressed into a liquid state and readied for transportation to a storage facility underground.
The various components of the process are not new -- the chemical industry has been using the technology for some time.
Damian Muller, Vattenfall's Head of Communications for the CCS project, told CNN: "The pilot stage is going to last five years and will deliver 100,000 tons of CO2. We have a signed agreement with Gaz de France [a French state-owned utility], which starts in 2009 which will allow us to test the storing of CO2 in a depleted natural gas field in Altmark, [Germany]."

CO2 injection begins in Virginia project, Sequestrating CO2 & Boost CBM Production - Carbon Capture Journal
Storage, Feb 20 2009 (Carbon Capture Journal)
- DOE's Southeast Regional Carbon Sequestration Partnership (SECARB) began injecting CO2 at the test site in Russell County, Virginia, in mid January 2009.
An existing coalbed methane well has already been converted for CO2 injection, and two wells have been drilled to monitor reservoir pressure, gas composition, and the CO2 plume.
The targeted coal seams are in the Pocahontas and Lee formations and range from 1,400 to 2,200 feet in depth and from 0.7 to 3.0 feet in thickness. One thousand tons of CO2 will be injected over a 45-day period.
The site was selected because it is representative of the Central Appalachian Basin, an area of about 10,000 square miles located in southern West Virginia and southwestern Virginia. This area has been assessed by researchers to have the capacity to store 1.3 billion tons of CO2 in the coal seams while increasing natural gas production up to 2.5 trillion cubic feet.
The Central Appalachian Basin CO2 Storage Project will explore the concept of multiple use of subsurface storage volume. Injecting CO2 into coal seams boosts coalbed methane recovery, which provides an immediate commercial benefit and offsets infrastructure development costs, while providing long-term storage of CO2 in the formation—a win-win situation.
