Okay? And how are we supposed to deal with the emissions currently in the atmosphere? Even if we abandon all technologies that generate greenhouse gases overnight, we still have shit in the atmosphere warming the planet.
The most compelling strategy I’ve heard is biochar. You immolate organic matter in a medium like nitrogen so you don’t get carbon dioxide, and then you bury the char or use it as fertilizer. The char is relatively stable so shouldn’t create much in the way of carbon dioxide once it’s formed, and because you make it in an oxygen-less atmosphere you don’t get more greenhouse gases from making it.
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.
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.

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

Peat, too! It’s one of the best carbon sinks we currently have.
Ah. I didn’t think of algae. Might be a good reason to harvest all the algae blooms from the fertilizer run off.
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.

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.
