[Terrapreta] Dynamotive demonstrates fast-pyrolysis

[Shengar at aol.com]

Hi All,   
At least TP gets a final word on this Biopact Blog story on Dynamotive's  200 
biomass tons / Day  Bio-Oil pyrolsis operation, which is optimized for  fuel 
not char. I recall when I first read of Dynamotive , a year or more ago,  they 
didn't speak of char and soils at all.
 
 
 
 Dynamotive demonstrates fast-pyrolysis ;
 
 
"In a very interesting side-development, Dynamotive also announced that it  
is experimenting with biochar ('agrichar', 'terra preta') which could lead to  
the production of carbon-negative fuels  (more _here_ 
(http://biopact.com/2007/05/carbon-negative-biofuels-dynamotive-to.html)  and _here_ 
(http://biopact.com/2007/06/carbon-negative-biofuels-and-biochar.html) ). By storing a 
carbon-rich fraction of the  pyrolysed biomass in agricultural soils, a low-tech 
carbon sequestration  technique can be developed. The process has _shown_ 
(http://biopact.com/2007/06/research-confirms-biochar-in-soils.html)  to result in 
increased yields for the (energy)  crops that are planted on such improved soils."

P. S. I think Jon & Sean are contending around the complicated soil gas  
emissions questions about TP.
My  understanding is both TP and healthy organic soil increase CO2, but the 
over all  GHG effects are lower because of less Methane and  N2O emissions.
