Question to those in the know about this tech: Once captured, what do we do with all that CO2 saturated limestone?

From an article in late 2022, I found “Heirloom removes that CO2 by heating the limestone into a powder and stores the extracted CO2 underground” which leads me to believe this isn’t actually solving the problem, only sweeping it under the rug.

Where do you think the carbon came from in the first place? Fossil fuels don't create carbon, they are carbon. It's not shoving it under the rug, it's putting it back where it came from.

I believe one thing they're planning on doing is selling the CO2 to certain concrete manufactures. Another thing is putting the CO2 back underground through certain processes!

If you put it “back underground”, wouldn’t it just get released again TBD?

Capture it, then use it for other purposes, but don’t release it again and don’t bury it hoping our grandchildren’s grandchildren will know not to go digging there.
