gevo Gevo: an ‘advanced biofuels’ start-up• Founded 2005, based in Englewood, Colorado• Experienced & successful management team-over 150 years of experience in large
scale industrial bioprocessing and renewable chemicals, fuels, plastics• 1 million gallon per year demo plant in St. Joseph, MO with ICM• >169 patents & applications including exclusive licenses from Caltech, UCLA
(isobutanol pathway) and Cargill (cellulosic sugars)

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.
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
