Coal started its life a very long time ago, as biomass. As it turns out, on a dry basis, coal and wood yield similar results in terms of CO2 produced (kilograms of CO2 per unit of potential energy). But wood and coal do not have zero moisture content (MC). It is water in the solid fuel that causes CO2 emissions to increase over the dry weight ...
