It's easy to forget why there is a bit of a challenge to getting C02 out of the air: there's so little of it, comparatively.
In order, air is, broadly, made up of the following:
Nitrogen: %78.084
Oxygen: %20.946
Argon: %00.934
C02: %00.042
The stuff is essentially beyond a rounding error - it really gives one an appreciation of the "either don't release it, or capture it at the point of release" sentiment, and for the difficulties in making carbon capture outside of these scenarios be even slightly cost-effective. It's great to see progress on this front.

- stavros 5y agoHaha, no worries, it was just odd to see.

- this_was_posted 5y agoCould burning biofuel to generate highly concentrated co2 cheapen the process? This way there would also always be energy available for the capturing process and the capturing plants would be mostly just plots of land with plants on them.
- iSnow 5y agoI believe making charcoal out of the biomass would be much more energy efficient, no?

- GOONIMMUNE 5y agoMy understanding is that this is the central idea behind BECCS (mentioned briefly in the article) https://en.wikipedia.org/wiki/Bioenergy_with_carbon_capture_and_storage https://en.wikipedia.org/wiki/Bioenergy_with_carbon_capture_...
- nxpnsv 5y agoI know this is annoying, but why % first, and why 2 leading zeroes. It just looks odd. :D
- akie 5y agoCultural habits?
- nxpnsv 5y agoMost likely, but what culture?
- heavenlyblue 5y agoIt makes numbers easy to compare visually - one doesn’t need to analyse them positionally.
- stronglikedan 5y agoOnly when justified ;-)
