Biorefinery of the Future
Five to ten year outlook Newset technologies are unlikely to be included Only well-established technologies will be considered TRL 8+, FEL-3 cost estimates High value products Low to medium risk technology EtOH industry not known for taking chances ABLC 2018, Washington, D.

Oil Production History
First commercial (drilled) oil well Drake Oil Well Source: Library of Congress First commercial catalytic cracker en.wikipedia.org/wiki/Fluid_catalytic_cracking Production Growth 1859 1915 1862 First oil refinery (kerosene) Standard Oil Refinery A, Richmond, CA, 1914 Credit: Richmond Public Library 1909 Motor fuels exceed kerosene production ABLC 2018, Washington, D.

Ethanol Production History
US Gov’t incentivizes ethanol production 1979 Clean Air Act Amended 1992 Today Production Growth 2018 1975 US Begins phasing out TE Lead 1980s Oxygenates include MTBE and ETBE 2000s MTBE replaced by ethanol ABLC 2018, Washington, D. C. © 2018, Saille Consulting, LLC
