BISMARCK, N.D. (AP) _ The Great Plains Synfuels Plant in central North Dakota has reached a milestone of shipping carbon dioxide to Canada, where it's used for enhanced oil recovery.
Bismarck-based Basin Electric Cooperative owns the Great Plains plant near Beulah. The company says the 25 millionth metric ton of carbon dioxide arrived in Canada on Sunday.
The factory makes natural gas from coal and has been capturing CO2 since 2000. The carbon dioxide is piped 205 miles to oil fields in southern Saskatchewan, where it's pumped underground to force oil to the surface.
Carbon dioxide emissions are widely blamed for global warming.
