Since its founding, DuPont has been on the forefront of some of the greatest innovations in science. Today, the company is committed to leveraging its expertise in biotechnology and engineering to create sustainable solutions essential to a better, safer, healthier life for people everywhere.

Similarly, BP is one of the world’s largest energy companies, providing its customers with fuel for transportation, energy for heat and light, retail services, and petrochemicals products for everyday use. BP’s decision to devote a significant level of resources into widening the availability of biofuels is part of its strategy of identifying low-carbon or renewable fuels for the future.

DuPont’s partnership with BP is to develop and bring advanced biofuels to market to expand the use of biofuels in gasoline.

Biobutanol will be the first advanced biofuel available. It offers a number of advantages and can help accelerate biofuel adoption in countries around the world. It provides greater options for sustainable renewable transportation fuels, reduces dependence on imported oil, lowers greenhouse gas emissions, and expands markets for agriculture products worldwide. Using existing processing technology, the first commercial volumes of biobutanol will be available in 2008. In a second phase, an improved conversion technology will be used to broaden commercialization in 2010. This is a real solution to a real global challenge.

Biobutanol Supports Agriculture

• Produced from the same agriculture feedstocks as ethanol (i.e., corn, wheat, and sugar beet/cane).
• Supports global farmers as it provides another or expanded marketing opportunity for essential agriculture products, thus enhancing value to farmers.

Biobutanol’s Synergy with Ethanol

• Uses existing ethanol capacity can be retrofitted to biobutanol production.
• Produced from same agriculture feedstocks as ethanol.
• Reduced vapor pressure enhances co-blend synergy with ethanol.

Biobutanol’s Performance Benefits

• Easily added to conventional gasoline, due to its low vapor pressure.
• Contains energy content closer to gasoline. This is important as the amount of biofuel in the fuel blend increases.
• Provides better fuel economy versus incumbent biofuels
• Able to be blended at higher concentrations in gasoline.
• Increases the maximum allowable use in gasoline up to 16% volume.
• Less susceptible to separation in the presence of water, that allows its use in existing distribution infrastructure.

Biobutanol’s Environmental Benefits

• DuPont and BP are currently carrying out detailed calculations of biobutanol’s Well-to-Wheel/Life Cycle Analysis emission performance with initial indications that biobutanol delivers emission reductions that are at least as good as ethanol.
• Biobutanol’s low vapor pressure (lower than gasoline), means that vapor pressure specifications do not need to be compromised leading to higher VOC emissions (i.e., no requirement for a vapor pressure relaxation).

Biobutanol’s potential is limitless, and its implications are far-reaching. From an environmental sustainability, performance, or energy-security perspective, biobutanol is second to none. DuPont is proud and excited to be working with BP on this amazing scientific discovery that will improve our environment and our lives.
