Industry average grain to Gevo fuel
Grain to Gevo fuel with biomass steam
Optimized grain to Gevo fuel with biomass combined heat and power
Values based on GREET model by Argonne National Laboratory except for “Grain to Isobutanol with Biomass Heat/Energy “ based on Econergy Study for ICM. Ethanol values converted to Gevo hydrocarbon basis using the energy requirement for Gevo hydrocarbon manufacture compared to the energy requirement for ethanol.

gevoThe benefits of Isobutanol as an oxygenate
Benefits:• Lower RVP = easier to meet clean air act• Higher Energy Density= greater miles/gallon• Lower oxygen content = possibility for higher add’n rates• Lower water solubility = add at the refiner or blender
