Since 2003 DuPont and BP have worked in partnership to develop advanced biofuels with properties that can help overcome the limitations of existing biofuels. That work has now progressed to the point where they are able to bring the first product to market. The companies’ joint strategy is to deliver advanced biofuels that will provide improved options for expanding energy supplies and accelerate the move to renewable transportation fuels, which lower overall greenhouse gas emissions.
The companies are leveraging DuPont’s world-class biotechnology and bio-manufacturing capabilities with BP’s fuels technology expertise and market know-how. By pooling their knowledge and expertise, the two companies aim to be the world leaders in the development, production and growth of advanced biofuels, which today account for less than 2 percent of global transportation fuels. Current projections show that biofuels could become a significant part of the transport fuel mix in the future – possibly up to 30 percent in key markets.
The first product to market will be biobutanol, which is targeted for introduction in 2007 in the United Kingdom as a gasoline bio-component. DuPont and BP are working with British Sugar, a subsidiary of Associated British Foods plc, to convert the country’s first ethanol fermentation facility to produce biobutanol. Additional global capacity will be introduced as market conditions dictate. A feasibility study in conjunction with British Sugar is already under way to examine the possibility of constructing larger facilities in the UK.
“DuPont firmly believes that biology will help us reduce our global reliance on fossil fuels,” said DuPont Chairman and Chief Executive Officer Charles O. Holliday, Jr. “Today we are demonstrating how DuPont’s unique scientific capability provides solutions that are sustainable, renewable and matched to real world needs. Biobutanol is just the beginning of new solutions DuPont can offer to transform global economies by improving our use of renewable ingredients and natural processes to deliver products for a better, safer, healthier world.”
“BP has a history of seeking, and delivering, ways to reduce greenhouse gas emissions both from our own operations and from the products we sell,” said Lord Browne, chief executive officer of BP. “Transportation is an important area to address since it accounts for around 20 percent of global emissions and in the short to medium term increased blending of bio-components represents one of the few real options for progress in this area on a global scale.”
wwBoth companies recognize that while existing bio-components have proven to be an excellent starting point for the introduction of biofuels and will continue to play a major role in the future, there are issues that need to be addressed to increase market penetration. In particular, compatibility with existing fuel supply and distribution systems, the ability to blend in higher concentrations without requiring vehicle modifications, and fuel economy were identified as areas where improvements are needed.
This next generation of biofuels will help deliver on these targets. Biobutanol has low vapor pressure and tolerance to water contamination in gasoline blends, facilitating its use in existing gasoline supply and distribution channels. It has the potential to be blended into gasoline at higher concentrations than existing biofuels without the need to retrofit vehicles and it offers better fuel economy than gasoline-ethanol blends, improving a car’s fuel efficiency and mileage.
Biobutanol also enhances the performance of ethanol blends in gasoline by, among other things, reducing ethanol’s impact on vapor pressure, one of the issues that limits wider use of ethanol in existing gasoline distribution channels.
Initial production of biobutanol will be based on an existing technology, enabling early commercial market introduction. In a second phase, development work on a new biotechnology process using a higher conversion technology is already under way. Production is intended to utilize a range of feedstocks such as sugar cane or sugar beet, corn, wheat, or cassava and, in the future, cellulosic feedstocks from fast growing “energy crops” such as grasses, or “agricultural byproducts” such as straw and corn stalks. Since production of biobutanol is similar to ethanol and uses similar feedstocks, existing ethanol capacity can be retrofitted to produce biobutanol.
Biobutanol will provide significant environmental benefits over petroleum-derived transportation fuels, reducing overall environmental emissions of greenhouse gases. Biofuels help maintain, and potentially even reduce, the overall volume of carbon dioxide emissions entering the atmosphere. This is because the plants used to produce biofuels absorb carbon dioxide as they grow, while the resulting biofuels emit roughly the same amount of carbon dioxide as conventional fossil fuels when they are burned. While greenhouse gases also are generated in the production of biofuels, the net effect is still lower than using conventional fossil fuels.
This partnership is consistent with DuPont’s strategy to deliver sustainable growth by increasing shareholder and societal value while reducing the environmental footprint along value chains. From seeds and crop protection products to next generation biofuels technology, DuPont is delivering a portfolio of new products and transformative solutions that will accelerate both the adoption and growth of biofuels worldwide through its DuPont Biofuels business. To implement this strategy, the company has conducted leading-edge biotechnology research for more than 10 years. In 2003, the U.S. Environmental Protection Agency presented DuPont with its annual "Presidential Green Chemistry Award" for the company’s research leading to the development of its first bio-based product, Bio-PDO™. The partnership with BP extends the technological capabilities demonstrated with Bio-PDO™ to an even larger and more urgent market opportunity for biofuels.
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. It follows on from the company’s announcement of BP Alternative Energy – a dedicated alternative energy business which is active in solar, wind, hydrogen and combined-cycle-gas-turbine (CCGT) power generation – and the establishment of a biofuels business within its Refining & Marketing Business. The company also recently announced its intention to fund an Energy Biosciences Institute attached to a major academic centre, the first such facility of its kind in the world.
BP is of 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 items. It is the largest oil and gas producer in the U.S. and one of the largest refiners. BP also has a global network of around 25,000 service stations.
