SW: →Antelope Valley CO2 capture demonstration project: - add section
Some state representatives are seeking $100 million in state support to match the federal grant. The project's initial engineering and design work should be completed by the end of 2010, Basin spokesman Daryl Hill said. North Dakota's Industrial Commission, which oversees a state coal research fund, put up $2.7 million for the study, which equaled half its expected cost.<ref name="dw">Dale Wetzel, [http://www.businessweek.com/ap/financialnews/D9H9BVF00.htm "ND PSC candidate backing carbon dioxide project"] Bloomberg, July 30, 2010.</ref>
In August 2010, [[Basin Electric Power Cooperative]] said it was searching for customers to buy the carbon dioxide it plans to retain from the experimental Antelope Valley power plant. A potential buyer is the oil industry, which uses carbon dioxide for enhanced oil recovery in some geologic formations. Designers hope the project will be able to capture up to 1 million tons of the gas annually. The legislative committee's chairman, Sen. Rich Wardner, R-Dickinson, said he believed a surge in carbon dioxide demand was in the offing for western North Dakota's oil industry.<ref name="dw">Dale Wetzel, [http://www.businessweek.com/ap/financialnews/D9HMKHK84.htm "Basin Electric project still seeking CO2 customers"] Bloomberg, August 19, 2010.</ref>
Basin Electric Power Cooperative provides wholesale electric power to rural electric cooperatives in nine states. One of its subsidiaries, [[Dakota Gasification]], operates the [[Great Plains Synfuels Plant]] near Beulah, in west-central North Dakota. Great Plains processes lignite coal to make [[syngas]] and retains much of the carbon dioxide in the process. It ships the gas by pipeline to southern Saskatchewan, where oil producers pump it underground to increase oil production. The plant retains about 3 million metric tons of carbon dioxide annually. Basin believes the pipeline has additional capacity to ship carbon dioxide from the Antelope Valley project, and additions could be built to supply the gas to western North Dakota oil producers.<ref name="dw"/>
The carbon dioxide retention process to be used at Antelope Valley is being developed by HTC Purenergy Inc. of Regina, Saskatchewan and Doosan Babcock Energy, an English company that has its U.S. headquarters in Atlanta. Basin said the carbon dioxide that cannot be sold could be pumped underground into saltwater aquifers in western North Dakota for storage. One large aquifer is beneath the [[Freedom coal mine]], eight miles northwest of Beulah, which supplies coal to the [[synfuels]] plant and Antelope Valley station.<ref name="dw"/>
