Carbon Negative Fuel Source?

Time Magazine, The Independent (UK) profile pyrolysis of biomass into biochar as CO2-reducing strategy
December 8, 2008: Bio Fuels Digest

Pyrolysis and biochar have surfaced as climate change-fighting techniques in separate reports in TIME and The Independent (U.K.). Both articles point to the rich, dark “terra prete” soils found in the Amazonian basis which are, scientists say, the result of ancient civilizations adding biochar to their soils.

Biochar is the charcoal byproduct of the pyrolysis process that traps up to 90 percent of carbon from biomass. Entrepreneurs from the US and the UK have proposed large-scale pyrolysis projects, in which biomass absorbs CO2 from the atmosphere, and the resulting carbon is returned to the soil when the biomass is turned into biochar through a pyrolysis process. Other by products from fast pyrolysis include renewable biogas and pyrolysis oils that can be used in generators or refined into renewable fuels.

The Independent story tracks a venture proposed by the Green & Blacks chocolate and Future Forests, focused on operations in Belize and England. The TIME article highlights efforts by US-based Epidra to develop large-scale pyrolysis systems.
