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

1.29K 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?

Carbon capture uses so much energy and is so expensive that it’s easier, cheaper, and cleaner to just use clean/renewable energy in the first place instead of burning things to generate energy and having to add carbon capture to it. Carbon capture at emission sources also hasn’t lived up to the efficiency standards that it’s been advertised at. The tech just isn’t there, but the tech *is* there for renewables. The biggest source of emissions for most industrial processes is the energy use, which we can mitigate by electrifying processes and continuing to build out more renewable generation to provide that electricity.
