So, unless we want to remove a massive amount of fresh water from the ecosystem, we also need to invest energy in drying out the wood well below natural humidity levels (transport to a desert maybe?) on top of electrifying what is currently a diesel and gas heavy industry (cutting and transporting logs with heavy machinery).
There's definitely lower hanging fruit for getting C02 out of the cycle.
They need to go into a deep enough pit where the methane produced from anerobic breakdown won't reach the atmosphere.
The conditions that created the lignite coal and peat simply aren't that easily reproducible, especially with large volume of wood (rather than ferns over thousands and millions of years).
