Could something like this be used to make cement?
Imagine capturing CO2 to turn it into cement, used for constructions.
Pardon my ignorance, though.

We don't use CO2 to make cement, we use limestone, and CO2 is the byproduct of heating the limestone to make reactive calcium.
Do you know ferrock?
It is a kind of cement that uses CO2 to cure.
You can store CO2 and sell it to construction companies (to cure ferrock), to energy storage companies (who like to put the CO2 in huge bubbles nowadays, go figure), or to agricultural corporations (who enrich greenhouses air in CO2 to accelerate growth).
