Life cycle analysis of fuel production from fast pyrolysis of biomass

► Pyrolysis gasoline can reduce WTW GHG emissions by over 60% to petroleum gasoline. ► A tradeoff between fuel yields and GHG reductions by H2 source were observed. ► Probability distribution functions for key parameters were developed. ► H2 source and biochar usage make statistically significant GHG emissions changes. ► Highly uncertain biochar characteristics affect the WTW results significantly.
