Great news , thanks Ron,

This statement in the ASES down load is contrary to the potential that char has as a soil carbon sink:

"Because char residue from pyrolysis
processes would contain about 10% of the
original carbon, the carbon storage component
that would arise from the incorporation
of the char into soils would likely be about 1
tC/ha/yr, compared with offset rates from
Table 1 for power systems on the order of 4
to 6 tC/ha/yr."


I must not understand these numbers,

? how does any combustion or IGCC system store carbon in soil?
? Are they just talking here about "Offsets"?

? The range of Tons of Charcoal per hector I have read has been from 1 to 16 ton/Ha?
