San Ramon, California & Federal Way, Washington [RenewableEnergyAccess.com] Chevron Corporation and Weyerhaeuser Company today announced a letter of intent (LOI) to jointly assess the feasibility of commercializing the production of biofuels from cellulose-based sources.The companies will focus on researching and developing technology that can transform wood fiber and other nonfood sources of cellulose into economical, clean-burning biofuels for cars and trucks. Feedstock options include a wide range of materials from Weyerhaeuser’s existing forest and mill system and cellulosic crops planted on Weyerhaeuser’s managed forest plantations. “Chevron is investing in cellulosic biofuels because we believe they will play a role in meeting future energy growth,” said Dave O’Reilly, chairman and CEO of Chevron. “While there are several research and technology hurdles that will need to be addressed before large-scale commercialization of cellulosic feedstocks occurs, we believe this partnership will accelerate the achievement of that reality.” “Crops created for and dedicated to fuel feedstocks offer the opportunity to augment value creation from our managed forest lands,” said Steven R. Rogel, chairman, president and chief executive officer for Weyerhaeuser. “Working together we can create new, sustainable sources of biofuel.” Both Chevron and Weyerhaeuser already have separate research partnerships under way to accelerate the development of cellulosic biofuels. Chevron has forged alliances with the Georgia Institute of Technology, the University of California at Davis, the Colorado Center for Biorefining and Biofuels, and the U.S. Department of Energy’s National Renewable Energy Laboratory. Weyerhaeuser is collaborating with several research universities, national laboratories and technology-based companies in research on conversion of forest products into ethanol and other biofuels.
