This is simply untrue.
Grow woody biomass, and combust it in a reducing environment, and you get carbon. It's biologically inert. Bury it.
It's not difficult, or impractical, and even if you mix it into soil, it will remain sequestered for centuries or millennia.
It's just... charcoal. Why would we have to make coal in the way it was made in the carboniferous? Your doom posting doesn't make any sense.
