Another thing is of course that, we need to know more how these
technologies work in the real world by a lot more research and demo
projects.

Or simply CRS (Carbon Removal and Storage). A few years back when this
group came up with the names SRM and CDR, I argued for CRS, reasoning that
any CO2 removal method has to be accompanied by storage as a truly workable
carbon sequestration strategy. many cheers, -Ning

long-term sequestration of woody material.
2) I was told fresh wood sinks by itself before it looses water. Or
may be your are right it depends on what kind of trees? I'd love to
have some references on this.

Ecological carbon sequestration via wood burial and storage: A
strategy for climate mitigation and adaptation

Dear Andrew and all:
The question of bury or burn is an important one that is far from
resolved. One point emphasized by several people involved in
implementing climate mitigation strategies at the Heinz Center
workshop last week is that in general, there are many other
competitions with biomass u
natural forest can regenerate
hundreds of thousands of seedlings over just a few square miles. The
limitation is space, mostly light, not seeds.

take a long time to ramp up, a small number of countries/entities

John: Our most recent estimate of wood harvest and storage (WHS), or
'burying wood' comes to $50/tCO2. The cost mainly comes from
harvesting and (largely) in-situ storage. Best Regards! -Ning Zeng
