I dont even know where to to start with the math, but I always wondered if there is not a viable carbon capture business in just growing and burying plants.

Get some fast growing plant like Japanese Knotweed or bamboo, grow it out for a year, harvest and dump the biomass into a decomissioned mineshaft to minimize contact with the atmosphere. Rinse and repeat.

One does not even need to bury anything. For example miscanthus giganteus plantation will increase carbon storage in the soil by simply increasing the mass of rhisomes and excreting various organic compounds into the soil. Obviously this has it's limits since the ground will be saturated after couple of years but it's is still a progress compared with a field with no plants.
