The dream of carbon air capture edges toward reality

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.

I know this is annoying, but why % first, and why 2 leading zeroes. It just looks odd. :D

Cultural habits?

Most likely, but what culture?

It makes numbers easy to compare visually - one doesn’t need to analyse them positionally.

Only when justified ;-)

Oh man, I didn't expect seeing it written "C-zero-two" to bug me that much :P

(I'm sorry - I have long since given in to this strange urge to type short alpha-numerics as hex. I can't justify it; it's habitual; and when I catch it, I always hope no-one is using a font that highlights it.)

Haha, no worries, it was just odd to see.

Could 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.

My understanding is that this is the central idea behind BECCS (mentioned briefly in the article)

I believe making charcoal out of the biomass would be much more energy efficient, no?
