Low-Cost CO2 Mitigation in Electricity, Oil, and Cement Production

[altenergygeek]

[B]While most CO2 emitting companies would not mind shelling out a few dollars in order to capture and store the CO2 and in the process do the world a lot of good, very few of them can really afford to spend $30-40 per T of CO2 sequestered!

At the same time, several [URL="http://powerplantccs.com/blog/2010/03/low-cost-co2-mitigation-in-electricity-oil-and-cement-production.html"]low-cost opportunities exist for scrubbing CO2 from waste gas streams[/URL], utilizing spontaneous chemical reactions in the presence of water and inexpensive or waste alkaline compounds. These reactions convert CO2 to bicarbonate or carbonate in dissolved or solid form, thus providing CO2 capture and low-risk CO2 storage underground, in the ocean, or in some cases on land.

Well, while these are indeed very interesting areas quite in the realm of possibility, I am not sure if the entire techno-economic feasibility studies have been completed for these, in order to put up pilot plants.

Any information in this context of mineral carbonation method for CO2 sequestration will be most welcome.
