GC-MS chromatogram of the liquid products obtained after hydrodeoxygenation of angelica lactone dimer. Considering that levulinic acid is available with more than 80% conversion from raw biomass, a field-to-tank yield of drop-in, cellulosic gasoline of more than 60% is possible, the researchers claimed.

If cellulosic feedstocks were planted on cropland that is currently used for ethanol production in the US, more ethanol (+82%) and grain for food (+4%) could be produced while at the same time reducing nitrogen leaching (-15 to -22%) and greenhouse-gas (GHG) emissions (-29 to -473%). —Davis et al. —William Parton.

Cost of algal biofuel production is still a major challenge and the Energy Department has made reducing the costs of both algae production and conversion of algal intermediates to fuels significant goals. Knoshaug, Ryan Davis, Lieve M.L. In traditional processes, the algae produce lipids that get converted into fuels.
