Fast-growing trees, which are then burnt to charcoal (and some energy), which is then put in the soil as biochar.
Could be very cheap/low-tech and at the same time improve soils.

Either way, these methods greatly improve the land-use efficiency of growing trees for carbon capture/storage, as it is stored in the soil over many years, not only in the living trees. "putting coal back in the ground" as it were.
