Way above the ~$18 price tag California puts on a ton of carbon. But this method has the benefit that it returns oxygen to the atmosphere instead of locking it away, bonded to carbon, for eons.
Perhaps added incentives can be made to methods that not only sequester carbon, but also return oxygen back to the the atmosphere.
- pengaru 5y agoIt also has the benefit of apparently producing a high purity carbon sheet having existing industrial applications. The cost could be offset substantially if they're producing inputs for high margin industries like carbon fiber products...

- unmole 5y ago> Breathing and aerobic bacteria and oxidizing reactions all throughout the chemistry of life. None of these are in any way constrained by the concentration of oxygen. The carbon dioxide in the atmosphere is 0.04%. The amount of captured carbon that will be broken down through technology will be a fraction of this. It is unlikely to change the concentration of oxygen in anyway.
- robbedpeter 5y agoJust to clarify, it's about $100 for 500 lbs of carbon, so $400 per ton of carbon flakes.
