Bio-Based Materials Vice President John Ranieri Speaks at CleanTech

    NEW YORK, May 16 /PRNewswire-FirstCall/ -- At a conference for
 investors here today, DuPont Bio-Based Materials Vice President & General
 Manager John Ranieri said the company's strategy for growth in alternative
 energy technologies is based on a solid product portfolio and a unique
 pipeline of new technologies that are supported by a strong intellectual
 property estate.
     "The world needs new sources of clean energy now," Ranieri said.
 "Alternative energy is already an important market segment across several
 of our commercial product offerings, and we have strong pipelines that will
 further drive growth into alternative energy markets."
     DuPont's broad-based alternative energy portfolio includes:
     Photovoltaic Technologies: DuPont supplies eight of the nine key
 materials used in a solar panel. These products include conductive pastes
 and high-performance films that help the panel achieve higher power output
 and long life. Ranieri indicated DuPont will invest approximately $100
 million in the continued development of products and technologies for solar
 cells and panels.
     Biofuels: Last month DuPont announced the creation of a Biofuels
 business unit to deliver commercial products and pipeline opportunities to
 the biofuels market. This business includes the Pioneer Industry Select(R)
 program that is marketing 135 corn hybrids this season to improve the yield
 potential of grain ethanol production; the Integrated BioRefinery research
 program to develop technologies to convert entire corn plants and other
 cellulosic plant material into ethanol; and a research pipeline to
 accelerate commercialization of alternative biofuels technologies. DuPont
 sales to biofuels markets have more than doubled over the past five years
 to more than $300 million.
     Crop Genetics: "Over the past decade, agricultural biotechnology has
 emerged as a high value-driving technology in major crops such as corn,
 soybeans and cotton," Ranieri said. "Given growing market needs for energy
 alternatives, energy security and environmental sustainability, we believe
 the growth opportunities from Pioneer's position as a leader in seed
 genomics can begin to meet the growing demand for agricultural feedstocks
 that will be used to create new bio-based products."
     Fuel Cells: DuPont's product offering includes advanced materials such
 as DuPont(TM) Nafion(R) perfluorinated membranes, which have been used in
 fuel cells for more than 35 years, as well as high-performance membrane
 electrode assemblies (MEAs). DuPont is active in the development of both
 hydrogen and direct methanol fuel cell technology.
     DuPont owns one of the world's largest patent estates in biotechnology,
 covering both the rapidly growing agricultural sector and the emerging
 industrial sectors, and currently ranks second among patent holders in this
     "The growth potential from the pipeline outlined today is the result of
 the company's commitment to biotechnology and its market focus to deliver
 high-performance products that utilize clean energy technologies," said
     DuPont (NYSE:   DD) is a science company. Founded in 1802, DuPont puts
 science to work by creating sustainable solutions essential to a better,
 safer, healthier life for people everywhere. Operating in more than 70
 countries, DuPont offers a wide range of innovative products and services
 for markets including agriculture, nutrition, electronics, communications,
 safety and protection, home and construction, transportation and apparel.
