What is the Time-Frame for Required Feedstock Tonnages? … Introduction • 2012 – 2015 Time Frame: • Grain Ethanol 7-8 billion gal. • Cellulosic Ethanol 3-4 billion gal. (estimated 35-45 M tons biomass) • 2030 Time Frame: • Grain Ethanol 13-14 billion gal. • Cellulosic Ethanol 40-50 billion gal. (estimated 400-500 M tons biomass) Chart representing ethanol volumes predicted from the high oil case using the transition model for the 30x30 NREL report., 2006. Presentation_name
