  1. DuPont Biofuels:Building a Sustainable Future September 27, 2007

  2. Agricultural Inputs Plant Feedstocks Conversion to Sugars Fermentation Processes Biofuels Biochemicals • Leveraging Relationships and Expertise Along the Value Chain DuPont Biorefinery Value ChainCarbohydrates to Chemicals and Biofuels Seed Crop Protection CO Sugar 2 Starch Ethanol Biochemicals Biobutanol Bio-PDOTM Cellulose Differentiated Products Biofuels

  3. Biofuels Global Market Perspective Current Biofuel Challenges: PIPELINE COMPATIBILITY BIOFUEL PRODUCTION PRODUCTION COST FEEDSTOCK AVAILABILITY REFINERY BLEND FLEXIBILITY TERMINAL FUEL STABILITY RETAIL / AUTO INDUSTRY / CONSUMER FUEL EFFICIENCY – MPG VEHICLE MODIFICATIONS INFRASTRUCTURE MODIFICATIONS

  4. Biofuels Sustainability: DuPont’s 3 Targeted Solutions Improving corn bushels per acre and ethanol gallons per bushel Seed/Crop Protection Solutions Supplementing ethanol by developing and supplying next generation biofuels with improved performance Advanced Biofuels with Improved Performance Developing and supplying new technologies to allow conversion of cellulose to biofuels Cellulosic Ethanol Production

  5. Advanced Biofuels – Preferred Attributes InfrastructureChallenges and Opportunities • Uses existing biofuels value chain • Is easily added to gasoline used in existing vehicles • Is added to the fungible fuel pool using existing infrastructure to enhance sustainable growth • Is used in reasonable blend concentrations and requires no compromise in fuel specifications • Offers good value to consumers without performance compromise • Enhances the use of incumbent biofuels

  6. Biobutanol: Next Generation Biofuel RENEWABLE FEEDSTOCKS WORLDWIDE FUEL MARKETS DuPont & BP • Powerful partnership • Shared commitment • Global reach • Complementary capabilities

  7. Biobutanol: Provides Greater Options for Sustainable Renewable Fuels PIPELINE BIOFUEL VALUE CHAIN REFINERY TERMINAL • SAME AGRICULTURAL FEEDSTOCKS • UTILIZE ETHANOL PRODUCTION ASSETS • LIMITED WATER ABSORPTION • FUNGIBLE BLENDING COMPONENT • LOWER VAPOR PRESSURE AIDS REFINERS • LESS CORROSIVE • UTILIZE EXISTING INFRASTRUCTURE RETAIL / AUTO INDUSTRY / CONSUMER • BETTER FUEL CONSUMPTION • POTENTIAL FOR HIGHER BLEND LEVELS WITHOUT VEHICLE MODIFICATION • LOW VAPOR PRESSURE ALLOWS FOR POTENTIAL INCREASE IN ETHANOL BLENDING • PROMOTES USE OF EXISITING RETAIL PUMPS AND STORAGE

  8. Cellulosic Ethanol Production 40 Gal/Acre 391 Gal/Acre at 50% removal rate 155 Gal/Acre 310 Gal/Acre Images: www.ca.uky.edu & www.nativeaccess.com0

  9. Cellulosic Ethanol Infrastructure Issues • Conversion • Pretreatment • Enzyme Saccharification Cob Handling, Storage, Drying, & Transport Fermentation Production & Separation Feedstock ‘One Pass’ Harvest • Cellulosic biomass to the plant gate : • On-farm collection systems • Moisture issues • Storage • Transportation • Increasing yields / efficiencies Downstream Markets Same as ethanol Feedstock Production • Government Support • National Energy Agenda • Incentives & Funding

  10. Corn Cob Collection / Processing Build on existing grain harvest system Why Cobs? • 12-25% of the above ground stover • 2 times the bulk density of stover • 16% more carbohydrate than stover alone Collection options – one pass • Separate or • Grain/cob co-mingled “CCM” Separation options • On farm processing • Off-site processing Transportation and Storage options Future Visions

  11. DuPont Biofuels - Development Milestones 2007 2012 Seed & Crop Protection Solutions • Best Corn Hybrids – Ethanol Yield (now) • Direct processor – farmer connection (now) • Increased Ethanol – other options (in development) Biobutanol • Biobutanol market development launch in UK (2007) • UK Development Plant (2009) • Biobutanol Sales (2010+) Cellulosic Fuels • Demonstration Plant (2008) • Commercial Plant startup (by 2012)

  12. Meeting Food, Feed, Fuel, Materials Needs in a Safe, Sustainable Manner The Biotechnology Opportunity Thank you
