The limestone-derived derived material is simply lime (CaO). Where does this lime come from? Why, from driving carbon dioxide out of limestone. This has already been done for a number of centuries. Of course, it releases carbon dioxide. So, it seems that to get the lime to capture CO2 from combustion, one must first realease CO2 in making the lime. One of the commenters points this out. The article does not explain how the captured CO2 is to be stored. This is one of several articles in MIT Technology Today which feature new processes with seemingly miraculous environmental possibilities. The theory is never quite explained, and the practicality of these processes is very dubious. Just a warning!

If the U.S. federal government can’t extort fines from utilities in a carbon tax in order for Democrats to buy votes from its Free Stuff constituency, it is not interested. It never has been about the environment. It’s about the control of business for the purpose of buying elections.

Capture of CO2 is insanity. It is a trace gas. It always has been a trace gas. It always will be a trace gas.

Without CO2, plants die. With CO2, plants flourish.

Without plants, we die. With plants, we flourish.

If power plants pump out CO2, that is a GOOD thing.

The easiest way to capture Co2 is to grow plants and trees. It takes an Engineer to dream up an expensive system like this.

MIT had a group of guys create an alge that was put on top of coal smoke stacks, it ate the materials released AND it produced some coal oil to run a portion of the plant. That idea never seemed to make it to the level of roll out one would expect. There must be dozens of these great ideas, that never get farther than a test or two.

I wonder if the researchers at MIT consider the possibility that this is a wasted effort:

A problem: nearly one third of CO2 emissions occured since 1998, and it hasn’t warmed (http://wattsupwiththat.com/2012/12/06/a-problem-nearly-one-third-of-co2-emissions-occured-since-1998-and-it-hasnt-warmed/)

to get the lime to capture CO2 from combustion, one must first realease CO2 in making the lime.

Not only that, burning the coal or the oil to generate the heat to release the CO2 from limestone also releases CO2. The whole thing is nonsense.
