  • It’s also kind of obvious by accounting for concentrations why this kind of carbon capture is a fairytale, isn’t it. Trying to capture from a carbon source like an exhaust, you’ll see a gas that’s easily 80% CO₂, compared to the meager 0,04% (400ppm) concentration in regular air. My guesstimate is that you’ll easily produce more CO₂ than you’re able to capture just trying to move enough CO₂ molecules through the capture device, even if you’re 100% efficient in capture.

    Also a sidenote: I think carbon capture at the source has its use in combatting climate change, but we must not forget reduce > reuse > recycle. Carbon capture is very much recycling, so we should be careful to only do it for situations where it’s very hard to decarbonize.
