    Absolutely, I also think Biochar is very promising as one way to recapture atmospheric CO2 and to compensate further emissions.

    While I understood the production process to be a little different, the benefits of Biochar can’t be ignored.

    • low in energy consumption
    • low in recourse cost
    • very good scalable
    • no hidden science or process
    • the stored carbon can be used as a soil amendment

      The process may be a bit more complex than I understood, but my understanding is that the gist of it is to “burn” plant stuff in a way that doesn’t create carbon dioxide or other greenhouse gases. One way of doing that is to use a chamber flooded with nitrogen or similar inert gas. No oxygen means carbon can’t bind to two oxygen atoms to create carbon dioxide.

        I’m confused, how can you ‘burn’ anything without oxygen? Burn literally means to oxidize

          That’s why it’s in quotes. You’re subjecting it to high heat, which would normally cause it to burn, but because there’s no oxygen it chars instead.
