The Soil is the best place to Sequester Carbon, from Closed-Looped Pyrolysis of Biomass. Terra Preta Soils Carbon Negative Bio fuels, massive Carbon sequestration of Charcoal fraction,and 1/3 Lower CH4 & NO2 soil emissions, and 3X Fertility Too The main hurtle now is to change the current perspective held by the IPCC that the soil carbon cycle is a wash, to one in which soil can be used as a massive and ubiquitous Carbon sink via Charcoal. Below are the first concrete steps in that direction; Tackling Climate Change in the U.S. Potential Carbon Emissions Reductions from Biomass by 2030 by Ralph P. Overend, Ph.D. and Anelia Milbrandt National Renewable Energy Laboratory http://www.ases.org/climatechange/toc/07_biomass.pdf The organization 25x25 (see 25x'25 - Home) released it's (first-ever, 55-page )"Action Plan" ; see http://www.25x25.org/storage/25x25/d...ActionPlan.pdf On page 31, as one of four foci for recommended RD&D, the plan lists: "The development of biochar, animal agriculture residues and other non-fossil fuel based fertilizers, toward the end of integrating energy production with enhanced soil quality and carbon sequestration." and on p 32, recommended as part of an expanded database aspect of infrastructure: "Information on the application of carbon as fertilizer and existing carbon credit trading systems." If you have any other questions please feel free to call me or visit the TP web site I've been drafted to co-administer. http://terrapreta.bioenergylists.org/?q=node It has been immensely gratifying to see all the major players join the mail list , Cornell folks, T. Beer of Kings Ford Charcoal (Clorox), Novozyne the M-Roots guys(fungus), chemical engineers, Dr. Danny Day of G. I. T. , Dr. Antal of U. of H., Virginia Tech folks and probably many others who's back round I don't know have joined.
