Carbon Removal

[Joel Weber]

If we end up making an effort to remove carbon from the atmosphere, are we ultimately going to end up with giant piles of graphite?

We could remove some carbon with Ferrock and/or Novacem, or perhaps manufacturing bioplastic, using it once, and landfilling it, but it seems like graphite would be most efficient in that it doesn't require other materials as inputs to the process.

Graphite is a crystalline structure made of repeating units of carbon.

Carbon dioxide has oxygen so in order to get to graphite you would strip the oxygen and form C-C bonds. Not terribly efficient.

No, my guess is that we will end up with compressed CO2, not graphite.

Aren't they experimenting with a plant that takes carbon dioxide and turns it into oxygen and sugar? I think it's solar powered, too.
