Basin Electric Selects Powerspan's ECO2 Carbon Capture Process for Commercial Demonstration Project

Basin Electric Power Cooperative and Powerspan Corp. today announced the selection of Powerspan's carbon dioxide (CO2) capture technology, called "ECO2(TM)," for a commercial demonstration at Basin Electric's Antelope Valley Station, a coal-based electrical generation facility 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.

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

The demonstration will draw the equivalent of a 120 megawatt slipstream and will be designed to capture 90 percent of the incoming CO2. The captured CO2 would then be delivered by pipe to the existing compressor station at Dakota Gasification's adjacent Synfuels Plant and injected into Dakota Gasification's 205-mile pipeline system for delivery to Canada where it will be used in an EOR project.

The ECO2 process is a post-combustion CO2 capture process for conventional power plants that is differentiated from other approaches by its simpler capital equipment design and significantly lower energy consumption. The technology is suitable for retrofit to the existing coal-based, electric generating fleet as well as for new coal-based plants. The CO2 capture takes place after the nitrogen oxides (NOx), sulfur dioxide (SO2), mercury and fine particulate matter are captured. Once the CO2 is captured, the ammonia-based solution is regenerated to release CO2 and ammonia. The ammonia is recovered and sent back to the scrubbing process, and the CO2 is in a form that is ready for geological storage. Ammonia is not consumed in the scrubbing process, and no separate by-product is created.

Today's announcement is the result of the first competitive solicitation process for a CO2 capture demonstration at a coal-based power plant in the U.S.  Six companies responded to the request for proposal.  Powerspan's CO2 capture process was selected as the most promising low cost option for commercial deployment and for its ability to best integrate with Basin Electric's operations. The project is scheduled to move forward in 2009. The facility is expected to be operational in 2012.

This is a milestone in carbon capture technology, being the first demonstration of carbon capture on such a large scale in the U.S.  Some utility companies are ahead of the curve on these tecnologies, seeing the writing on the wall, seeing regulations requiring carbon capture in the future. Only time will tell whether this is the best technology, but is much further advanced in devopment than some of the more recently announced technologies and thus fits in with power generation companies more conservative nature.

Does anyone know how this project is being paid for? Is it DOE-funded, or is it entirely private funding?

Because it is being put into an existing CO2 pipeline for use in enhanced oil recovery, the CO2 actually has a market value. I don't know if the "value" is greater than the cost of separation, but at a minimum it should offset at least some of the project costs.

Dear Sirs, This CO2 capture technology is a great breakthrough! Anyway, please google "A New CO2 Elimination Tactic" and scan that idea in the Techrex (me) blog, on the 11thHourAction website, since it's a possible option for disposing of this carbon dioxide taken from the coal burning electric power plants in this way.

Hi
It's to see the coverage on this new plant proposed by Basic Electric. I do not know if this is the *first*, nor do I care about the title first, as long as they do the job correctly. I bring this up because recently ALSTOM and another company in Wisconsin announced a pilot scale project of CO2 capture from a 610 MW plant, but they are testing it only on portion of the plant and the details of the scale were not too clear from the press releases (Link: http://www.alstom.com/pr_corp_v2/2008/corp/49200.EN.php?languageId=EN&dir=/pr_corp_v2/2008/corp/&idRubriqueCourante=23132)

Will USA export the CO2 from their dirty Coal fired power plants to Canada?

We do have very neighbours, don't we?

[poetryman69]

we need to keep pushing energy independence. Every other political concern is secondary. If we want peace and a greener world we need to stop paying for oil wars and stop paying dictators for oil. If we want to revive the economy we need to stop giving our money away to oil tycoons in foreign lands. We need to spend that cash on domestic sources.

Capture of CO2 is very good, as a temporary solution, once you've captured it, you have the time to develop the technology to desintegrate the CO2, to C- carbon, and O oxygene, it is quite difficult now, but once it will be possible.
What plants do, they use CO2 and H2O, and green light (that specific vawelenght of light) to produce sugar, maybe we can do similar and produce food out of CO2, (soylent green) or if you reduce the CO2 in some way, you get a pure C which is a fuel, you can make coal out of it again.
Anyway, I think that it must be a way to destroy very hard covalent bonds in CO2, with use of solar energy of specific vawe lenght (green). CO2 is a fertile gas, it is only that we dont know yet how to use it properly.

Hi,

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.Salt Lake City electrician

i would have loved to see this demonstration. I think this is such a great concept. this is our future.

I like this post information very much.This is great electric informative post.

This Project is nice....Thanks for sharing....

this part of blog "The measure, opposed by private lenders and critics of an expanding federal government, was included in a package of proposed changes to an overhaul of the U.S. healthcare system." was very interesting, thank you!

This is good concept. In fact I say this is out future. I really love to see working of it. ECO2 is a post-combustion and regenerative process which uses ammonia-based solution to capture carbon-dio oxide.

[Electrician]

This is a big deal when it comes to carbon capture technology. I am proud that we have come this far. My dad is an electrician and has had some problems with this stuff at the plant he works at.

[Filipino Car Lease Broker Los Angeles]

Hopefully this is the best technology, like you said time will tell.

[Dentist Hollywood]

Interesting that the ammonia-based solution can be regenerated to release the CO2 and ammonia without an after-effect of an ammonia by-product.

Neat information, thanks for posting it!

[fish tv]

I thought Antelope Valley was in California? I suppose there can be more than one, one million tons of CO2 is a lot!

[Furniture Stores in Los Angeles]

Never heard of this but glad that it consumes less energy.
