Wood is carbon neutral, not carbon negative. Trees take carbon out of the air and produce wood. When they die and decompose or burn, the carbon is released back into the atmosphere. Oil in the ground was produced during a time that wood was so abundant it almost suffocated the surface of the earth because nothing could decompose it. Somehow, brining all that oil back to the surface and turning it back into wood doesn’t seem like a good idea.
- nanomonkey 5y agoIf the wood is converted to syngas and biochar through gasification, the biochar is chemically inactive in the soil for thousands of years. The syngas can be used as an energy source. Bogs are actually great sinks of carbon, all of the biomass created in the bog will sink below the waters surface and remain inert.
- jazzyjackson 5y agoif you build with the wood then it doesn’t burn or decompose (yes, eventually, it will burn or decompose, but the more buildings on earth made of wood at any one time is carbon that isnt in the air.)
- ericd 5y agoEh if you keep it dry, it can hold it for a few hundred years. Permanent sequestration is ideal, but we’re really trying to minimize the area under the excess carbon curve in the near future to buy some time, so even shorter term stuff can be helpful. Reduction of excess carbon-ton-years is the way to think of it, IMO.
