Biochar and its potential role
To CleanTechies : « Biochar is charcoal type created by the pyrolysis of biomass, and differs from ordinary charcoal only in the sense that its primary use is not for fuel, but for biosequestration or atmospheric carbon capture and storage.»
«As much as 12 % of the world’s human caused greenhouse gas emissions could be sustainably offset by producing biochar. That’s more than what could be offset if the same plants and materials were burned to generate energy, »
Since CCS isn’t exactly the great solution some coal companies want to make us believe, perhaps biochar could sort of do the same, but at a lower cost.
