I was thinking something similar recently. I’d add that you could go beyond wood—crop offal more generally should be very very cheap, and we basically just need to bury it someplace where the carbon won’t leak out quickly.
We already use biomass to generate energy (expensive/inefficient), and energy to capture carbon (also expensive/inefficient); it seems like using biomass for carbon capture should be way cheaper/more efficient.
For a concrete example, in our county, there is a group called CHIPs that does wood fuel clearing on private land and uses it to create syngas and biochar. I need to check on their cost per acre for tree and brush clearing next week, so I’ll report back.

Pyrolysis and then burying the char as a soil amendment.
