Energy is a global concern for both developed and developing countries. One of the greatest challenges facing the energy industry today is the transportation fuels sector. Energy security, environmental constraints and a need for viable innovations offer unique obstacles and exciting opportunities. The global transportation industry requires new alternatives to petroleum fuels that are renewable, locally sourced, cost effective, and viable across all geographies with minimal environmental footprints.

At DuPont, we believe biology will help reduce the global reliance on fossil fuels. DuPont’s unique scientific capability will provide solutions that are sustainable, renewable and matched to real-world needs. Our integration of modern biological tools into our world-renowned chemistry and engineering capabilities has allowed us to become technology leaders in the development of renewably-sourced chemicals, and now fuels.

DuPont BioFuels will become an industry leader in providing advantaged products for agricultural energy crops, feedstock processing and advanced biofuels. A three-part strategy will deliver new technologies to the growing biofuels market to help biofuels become more competitive with petroleum. The strategy includes: (1) improving existing ethanol production through differentiated agriculture seed products and crop protection chemicals; (2) developing and supplying new technologies to allow conversion of cellulose to ethanol; and (3) developing and supplying next generation biofuels with improved performance.

“DuPont’s scientific capabilities in biofuels position us well for substantial growth. Our Biofuels business unit will leverage DuPont’s unique technology capabilities to accelerate commercialization of environmentally attractive, cost-effective solutions in the expanding biofuels markets around the world.” - Tom Connelly, DuPont Chief Innovation Officer

DuPont Danisco Cellulosic Ethanol

DuPont and the Genencor division of Danisco have formed a $140 million joint venture to commercialize the leading technology package for non-food based, cellulosic ethanol production. The joint venture will integrate science across the three-step ethanol production process to bring a proprietary, low cost cellulosic ethanol solution to market.

The joint venture will license its technology package directly to ethanol producers for global deployment, as well as through the establishment of regional cellulosic ethanol affiliates. The regional ethanol affiliates will invest in equity interests with strategic partners, including ethanol producers and energy companies, to enable the rapid deployment of the joint venture’s cellulosic ethanol technology at commercial scale. The joint venture’s technology package can be used both as a “bolt-on” to an existing ethanol plant -- expanding its capacity to accept cellulosic feedstocks -- or as the design basis for a stand-alone cellulosic ethanol facility. The first pilot plant will be developed through a partnership with the University of Tennessee in Vonore, Tenn. and will be operational next year utilizing corn cobs and switchgrass. The first commercial-scale production is expected in 2012.

Advanced Biofuels Partnership with BP: DuPont and BP announced in June 2006 an effort to bring the next generation of biofuels to market. The first product will be biobutanol. DuPont and BP have been working together since 2003 to help overcome the limitations of existing biofuels. The strategy is to deliver advanced biofuels that will provide improved options for expanding energy supplies while accelerating the move to renewable transportation fuels, which lower overall greenhouse gas emissions. These next generation fuels will harness DuPont’s advanced biotechnology capabilities, BP’s fuel market expertise and their joint process engineering know-how.

Biobutanol Advantages - Performance benefits

• Biobutanol formulations meet key characteristics of a ‘good’ fuel including energy density, controlled volatility, sufficient octane and low levels of impurities;
• Contains energy content closer to gasoline, so consumers face less of a compromise on fuel economy; and distributors have new opportunities to add more biofuels to transportation fuels;
• Gasoline blended with butanol is less susceptible to separation in the presence of water than ethanol /gasoline blends. As a result, it can easily be used in the industry’s existing distribution infrastructure without requiring modifications;
• Compatibility with current vehicle and engine technologies.

Environmental benefits

• The well-to-wheel life cycle analysis for biobutanol is currently in progress;
• Initial indications are biobutanol delivers greenhouse gas reductions that are at least as good as ethanol;
• The low vapor pressure (lower than gasoline) of biobutanol means that vapor pressure specifications will not be compromised, leading to lower volatile organic compound (VOC) emissions (i.e., no requirement for a vapor pressure relaxation).

Synergy with ethanol

• Existing ethanol capacity can be retrofitted to biobutanol production;
• Produced from the same agriculture feedstocks as ethanol (i.e., corn, wheat, and sugarcane);
• Reduced vapor pressure enhances co-blend synergy between biobutanol and gasoline containing ethanol.

Improving Ethanol Yield through Seed Technology and Crop Protection Products:

DuPont is a leader in the biofuels industry, driving product development that focuses on increasing yields for today’s farmers and biofuels producers.

DuPont business Pioneer Hi-Bred is the world’s foremost source of customized crop genetic solutions for farmers, livestock producers, and grain and oilseed processors. Through advanced grain characterization technologies, Pioneer classifies all its corn seed products for their ethanol yield potential. For 2008, more than 170 Pioneer® brand ethanol hybrids have been identified. Longer term, Pioneer is improving corn grain composition to provide increased ethanol yield and more valuable food and feed co-products.

Pioneer is also delivering innovations that improve supply chain efficiencies and better link farm operators to ethanol processors. The new Pioneer MarketPointSM web site resource provides farmers and grain buyers with an internet-based grain marketing system that enhances the efficiency of the buy/sell process and improves access to high quality grain supplies. The Pioneer QualiTrakTM system is a proprietary grain quality data information system to help farmers and processors improve the quality of grain for more efficient processing. For more information, visit www.pioneer.com.

DuPont Crop Protection is aggressively working to identify crop protection products to protect yields of crops used for the production of biofuels, including corn, sugar cane, sugar beets and switchgrass. The Tennessee Department of Agriculture recently approved a 24(c) registration for the use of DuPont™ Accent® herbicide on switchgrass for biofuels production in Tennessee. Other DuPont products in use for crops used in biofuels production worldwide include DuPont™ Steadfast®, Resolve® Q, Require™ Q, Accent® and Titus® herbicides* for corn; Advance® and Velpar® K for sugarcane and UpBeet®, Safari®, Debut® and Venzar® for sugar beets.
