Energy for a greener world

Here's how we clean up coal: we gasify it. Make it into clean-burning gas. That's what Dakota Gasification Company has been doing for nearly 30 years. Gas is a clean-burning fossil fuel. We don't say it's renewable, and we don't say it's green. We do say that gas is the cleanest fossil fuel, and more coal can be cleaned than ever before by gasifying it.

More than 40 years ago environmental groups called for everyone to quit polluting and clean up the environment. Our parent company, Basin Electric, listened. Scrubbing pollution from emissions is nothing new to Basin Electric or Dakota Gas -- we've been doing it for years. Some groups and individuals, however, believe that America's energy producers need to capture and store carbon dioxide (CO2) emissions. The issue is now under consideration before the U.S. Congress. Depending on the outcome, the work already done by Dakota Gas to capture and transport almost half of its plant CO2 emissions for permanent geologic sequestration in Canadian oil fields may become even more expensive. That concerns us and we hope it concerns you.

We believe that cleaning coal is necessary and attainable. Efforts to stop all coal-based energy production is not only unnecessary, it's impractical. Coal is an abundant American fuel source; it can help America achieve its goal of energy independence. Dakota Gas is something of an expert on this subject, and we have clean energy solutions for today and tomorrow.

Take some time to discover the benefits of gas made from coal. Talk with people in the energy industry. Learn more about how emissions are scrubbed from Basin Electric power plants, and book a tour at the Great Plains Synfuels Plant near Beulah, ND. We'll tell you more about how clean coal can be.

Coming clean

Dakota Gas has a strong commitment to the environment. We have improved our environmental footprint by achieving better reliabilities, improved efficiency, and meeting environmental goals. The Synfuels Plant meets or exceeds all state and federal laws. Based on stack emissions, it is the cleanest energy plant operating in North Dakota.

The Synfuels Plant features a unique flue gas desulphurization unit—or scrubber—that began operating in 1996. Installed to remove sulfur dioxide from the plant's flue gases, the scrubber is unusual because it uses anhydrous ammonia as the scrubbing reagent, producing a valuable fertilizer, ammonium sulfate marketed as DakSul 45®, instead of a waste product.

Dakota Gas is an international leader in the capture, compression, and sequestration of carbon dioxide. Since 2000, Synfuels Plant carbon dioxide that would otherwise be emitted into the atmosphere has been compressed and delivered through a 205-mile pipeline to Cenovus Energy oilfields near Weyburn, Saskatchewan, Canada, and more recently to nearby Apache Canada Ltd. oilfields for use in enhanced oil recovery.

As an environmental benefit, virtually all of the injected carbon dioxide will remain permanently sequestered in the depleted oil fields long after they have been abandoned. With three compressors in operation, Dakota Gas can now capture and deliver for sequestration 48.8 percent of carbon dioxide produced at the Synfuels Plant, which represents 16 percent of carbon dioxide produced from all the coal combusted from the nearby Freedom Mine—making it a proven technical and economic success for both Dakota Gas and its Canadian customers.
