Energy is a global concern for both developed and developing countries. Whether the focus is on energy security, climate change, population growth or the new reality of the global economy where demand for natural resources is increasing while availability is decreasing. The answer is the same: we need to think smarter about energy.

At DuPont, our portfolio of more than 35,000 products and new technologies includes real solutions to help address the energy issue. Our portfolio includes offerings in energy efficiency solutions for the home, the automobile as well as energy efficiency gains that can be made in manufacturing operations.

Perhaps most unique is the DuPont alternative energy portfolio – dynamic science-based products and technologies. At DuPont, we are providing products across the majority of the alternative energy portfolio with a full pipeline of new technologies that make us uniquely positioned to help address one of society’s toughest global challenges.

DuPont Photovoltaic Solutions: Alternative Energy from the Sun
Solar power is the conversion of sunlight into electricity using photovoltaics. According to DuPont and industry estimates, the market for solar energy is expected to grow 50 percent a year every year for the next several years, reaching several hundred billion dollars by 2020. DuPont expects that its sales of several product lines into the photovoltaic industry could exceed $1 billion within the next five years.

DuPont is a leading technology supplier to the photovoltaic industry, producing eight essential components used in a solar cell, representing a broad and growing portfolio of innovations for the industry. Our innovations are designed to enable solar modules to run more efficiently, last longer and provide safer and more environmentally sustainable solutions. Our products are key to the manufacture of both crystalline silicon and thin film solar cells and modules. They include films, resins, encapsulation sheets, flexible substrates and conductive pastes as well as high performance seals for solar cell manufacturing equipment.

We continue to invest in both capacity expansions to support the explosive industry growth and the development of new innovative technologies to address different applications within the industry. Recent announcements include the expansion of production capacity for DuPont™ Tedlar® polymer and films and launch of the new Tedlar® 2100 Series film products for photovoltaic modules.

What’s Next: Look for DuPont science to help deliver lower cost, higher efficiency solar cell components. For example, DuPont is currently working with the federal government and university partners to develop solar cells for military and commercial applications that are targeting a 50 percent solar module efficiency rate vs. the 15 percent efficiency of conventional technology.

DuPont BioFuels: Better Biofuels Using Non-Food Feedstocks
At DuPont, we believe biology will help reduce the global reliance on fossil fuels. We have developed a portfolio of biofuels solutions to address the need for alternatives to meet the global transportation energy needs. DuPont views the biofuels addressable market to be nearly $100 billion and is positioned to achieve real value through differentiated offerings. Biobutanol and cellulosic ethanol are two advanced biofuels technologies that will diversify the transportation energy sector and reduce reliance on petroleum.

Cellulosic Ethanol: Developing and supplying new technologies to allow conversion of cellulose to ethanol. DuPont Danisco Cellulosic Ethanol LLC, our new joint venture, is getting ready to bring our technology to market. With initial focus on corn cob, stover and switchgrass feedstocks and a new pilot plant under construction in Vonore, Tenn., DuPont and Danisco are accelerating the development of this next generation biofuel with a goal of delivering cellulosic fuels to market by 2012. For more information, visit: www.dupontdanisco.com.

Biobutanol Advanced Biofuel: Developing and supplying next generation biofuels with improved performance. Our first advantaged biofuel, biobutanol, is under development with partner BP. Biobutanol fuel properties are similar to gasoline. For example, biobutanol has: better energy content/better fuel economy, the ability to distribute through existing gasoline infrastructure, the ability to blend at higher concentrations than ethanol without the need for vehicle modification, a better environmental footprint than gasoline.

What’s Next: Cellulosic ethanol and biobutanol are heading to the market on an accelerated schedule. Look for progress in moving from R&D to commercialization through 2009-2010. In addition, DuPont is constantly evaluating other opportunities where biotechnology can create new energy solutions. More to come soon.

DuPont Fuel Cells: Accelerating the Power of Clean Energy
DuPont Fuel Cells is a global business that enables the advancement of fuel cell technology and products by providing the science and innovation to make fuel cells a commercial reality in the near and long term. Based in Wilmington, Del., its objective is to be the leading supplier of Proton Exchange Membrane (PEM) fuel cell membranes and components to power automobiles, electronics, and residences.

DuPont has more than 30 years of experience in fuel cell technology and market development. One of the first uses of fuel cells, based on DuPont™ Nafion® membranes, was by NASA in the 1960s for the Gemini program. DuPont invented, and continues to advance, Nafion® membranes and dispersions, which provide durability (lifetime is a key feature), performance (power and how much energy you can get out of the fuel cell) and lower cost. DuPont technology ties these materials together into integrated components (membrane electrode assemblies), some of which the company makes. The company has strategic development relationships with leading equipment manufacturers in the automobile and electronics sectors. For more information, visit: www2.dupont.com/Fuel_Cells/en_US.

What’s Next: In Oct. 2008, the U.S. Department of Defense recognized DuPont and partner Smart Fuel Cell AG as the winners of the Wearable Power Prize for developing the lightweight M-25 portable fuel cell pack for soldiers. In addition to its government-based efforts, DuPont is also striving to make fuel cells a commercial reality, with automotive, consumer electronics and residential power being the targeted markets.

DuPont Wind Energy: Powered by Science
DuPont is providing key innovations to the wind industry. Reliability of generating equipment is essential to the success of rapidly growing wind power. Wind provided more electricity than several other alternative energy sources in 2007 – approximately 1 percent of the global supply. By 2020, experts predict that wind will generate about 12 percent of world electricity needs, but the reliability of generating equipment is essential to the success of the rapidly growing wind power industry.

DuPont protects wind turbines by encapsulating the key components of the generator that protect them from the extreme heat inherent in the generation of electricity. Products range from DuPont™ Kevlar® mechanical paper, which reduces weight and improves the structural rigidity of wind turbines to DuPont Electrical Insulation Systems.

Coming Soon… DuPont in hybrid motors, wave technology oil and gas and many, many others.
