That would work for CO2 capture, if you could make the containers thick enough to withstand the pressure from the CO2.
Of course, the inherent problem in doing this is that you have to cool the chimney outlet. This could potentially take a tremendous amount of energy and be counter productive. Plus you have the collection of the dry ice which would seem to have the effect of blocking the output.
Simple methods of CO2 sequestration have been posited. For example, find plants that tend to take in the most CO2. Grow them and bury them.
As for finding dry ice, google it. Many locations sell blocks of dry ice. It is used frequently in parties to make the punch carbonated. There are at least 5 locations in my area.
It would make Power station very inefficient and electricity very costly, and then what are you going to do with all that dry ice.
Anyway CO2 is a great gas, it is essential to all life, without it plants cant grow, people can't eat.
Because it would require more energy than the power station could produce. You'd also be freezing other volatiles and water of the smoke. And just what do you do with all that bottled CO2 (very impure)?
It would be easier to absorb carbon dioxide with an alkaline solution than to build the refrigeration system to -100C.
They already do that with dry ice. Over in the US all you have to do is look in the Yellow Pages and you will see suppliers.
The freezing temp of carbon dioxide is no colder than -60C
so why can't power station not freeze the chimney outlet to about -100C and let all the Co2 turn into dry ice and fall from the air onto a plate which collects it all? Then simply bottle it and it will turn back into liquid or gas but it will be compressed because the ice is already much more dense than the gas so it would fill up the bottles with compression without the need for electric compression....
I think this is a solution to carbon capture why is this not possible, or is it?
Many thanks!
PS: If anyone knows where to get hold of some dry ice for experimenting please say.
