@momo @thomasfuchs well yeah. But the quickest and currently most effective carbon sequestration mechanism is photosynthesis, and the most reliable way to sequester it making charcoal, since charcoal doesn't degrade and when mixed into the soil it makes it impractical to recover and use as fuel.
Charcoal contains about 30% of the energy in the wood used to make it, and the creosote contains another fraction; using it to preserve wood also prevents it from decaying and releasing its carbon.

@momo @thomasfuchs so this improves outcome. But pyrolysis also produces gas which is much more difficult to sequester, so it's probably put to better use as fuel, possibly directly to help perform the pyrolysis.
Of course, that's for the long term. For the shorter to mid term, biomass carbon should be sequestered by making buildings out of wood, especially instead of making them from concrete or steel. Also a compounding effect there.

@momo @thomasfuchs Cause photosynthesis stores carbon but then releases most of it as biomass rots. Mature forests are more or less carbon neutral, not carbon sinks.
I'm not overly worried about deforestation from these practices, since by far the leading cause of deforestation is, per my understanding, clearing land for agriculture.
