    I don’t understand. Biomass already isnt CO2. Why do we take an extra step?

      Because when biomass rots, it creates CO2. By charring it you’re making the carbon more stable and less likely to become CO2 in the future. It also won’t rot when charred.

        So how do we produce biomass? Plant more trees? Which we already do. Then in how many year we cut it down and biochar it instead of using it reporposing it for something else? I’m kind of failing to see the benefit. Just seems like an alternative that isn’t really any better than some of the other good alternatives.

          Make algae ponds, harvest the algae, dry it, char it, bury it. Algae sucks up carbon dioxide like crazy, the downside being that it releases the carbon when it starts to rot. By charring and burying it, you’re helping to make sure that carbon doesn’t re-enter the atmosphere.

            Ah. I didn’t think of algae. Might be a good reason to harvest all the algae blooms from the fertilizer run off.
