I’d heard a fairly novel idea about farming trees and burying them as pulp in old mines, I’m sure it’s just ASKING for some kind of wild underground mine fire but … similar concept
I think that wouldn't work unless the mine is perfectly sealed.
The pulp would still get eaten and digested microorganisms and carbon released to air.
Plus there would be a ton of wasted carbon on harvest, pulpifying, transport...unless those are all done with green energy.
The reason why we have fossil fuels is because of the carbon that didn't get released to the atmosphere. It got trapped in a hypoxic water/swamps where bacteria and microorganisms couldn't decompose it.
We could build hypoxic lakes for disposal of large chunks of "organic" (as in alive) carbon to be sequestered...but it couldn't be done at a scale to even begin to touch what we've released. Maybe if we gmod some bacteria or plankton to chew it up and poop it up real fast. And put all the carbon we can find into the pit.
