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

1.28K 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?

Before anything else, consider that carbon capture is bullshit. While it works, the energy required to capture carbon is the same amount of energy obtained from breaking carbon, so even if you had 100% efficiency, which is not even possible as far as we know, carbon capture is useless if it is powered by carbon fuel, and redundant if you are using renewable energy (Instead of using the renewable energy to capture the carbon, you just use it instead of the fossil fuel energy source).

With that in mind, understand that carbon capture is a public relations thing. The only reason anyone does it is to look good, they don’t care about actually helping. They won’t bother making the process efficient then, as long as it gives them a good image.
