eli5: Why isn’t carbon capture used at emission sources?

1.27K views

I know that there is ‘legacy carbon’ in the atmosphere that needs to get removed but why aren’t we leveraging carbon capture as part of industrial processes (e.g. at the factory’s smoke stack, for example). Or maybe we are already?

It’s still uncertain whether carbon capture can actually work or not. At the moment we are pumping the captured carbon underground, but we have no real conception of if and for how long it actually stays there. It’s a sort of “good guess” that we are storing the carbon indefinitely. This is a big reason people argue against CCS in the first place.

The only legitimate way we would use CCS is on projects and industry that necessitate CO2 production. Perhaps concrete production or the like, although there are possible green alternatives. Besides that it is better for the environment and the bottom line to use that money for renewable development.
