Seems like a waste, why not turn biomass (CH2O) into CO2 and H2, use
the H2 for energy and bury the CO2? If you bury the C you also bury
nearly all of the energy content of the biomass.

Mind you, I am aware of reasons why you'd rather bury the charcoal (H2
is difficult to store, gasfication is capital intensive, it also costs
some energy to bury the CO2).
