Not necessarily. As other posters in this discussion point out, you can for instance create biochar from trees, which can be permanently planted in the ground, thus finally returning in the place of origin the carbon we earlier dug out in the form of oil and natural gas.
- bpfrh 8y agobut biochar requieres high temperatures, which usually produces co2... The problem with all this CO2 Storage is that we have a perfect storage for co2: Oil. Since we burn this storage, we release more and more of that CO2 without anyway to put it back to storage. The tree idea can maybe slow down the climate change, but it is in no way a solution, merely a short stopgap.
- ncmncm 8y agoBiochar can be produced (and is) by burning off the hydrogen. This is done by restricting oxygen availability, which the hydrogen preferentially bonds with. When the hydrogen is used up, you are left with charcoal, which powdered and mixed into the soil improves it wonderfully. Look up "terra nigra", invented in the Amazon basin.
