Researchers look beyond biofuels as substitutes for fossil fuels

Biodiesel and ethanol are good short-term solutions to curbing the nation's oil addiction, but they are not sustainable over the long haul, they say.
Biofuels could provide 37 percent of
But growth of crops such as corn and soybeans — traditional feedstocks — for biofuels production is energy- and water-intensive. And with limited farmlands available, feedstock production for fuel would have to supplant food production.
"There's never going to be enough cropland to replace all the petroleum we use" with biofuels, said Jan Auyong, an
In response,
The proposed center would centralize efforts under way around the state to develop substitutes for fossil fuel-based materials used in building products and transportation.
"I'm worried that people are promoting biodiesel without really looking at the life cycle costs," said Gail Achterman, a commissioner with the Oregon Transportation Commission and a key author of the proposal. "I doubt that people will feel good about replacing foreign imported (petroleum) oil with imported palm oil."
Like seed crops, leftover stems and leaves and woody materials can be broken down into their component sugars and starches for biofuels production.
Using biomass to make biofuels "is already very economically feasible in the
"We have huge assets, a huge feedstock in terms of land mass" for creating a supply stream of woody undergrowth, Benford said.
"A lot of the clean-energy focus in the proposal is realizing we need to transition to a society that is closing loops on production," said John Bolte, head of the bioresource engineering department at

The proposal is one of a handful of finalists submitted to the Oregon Innovation Council with the hope of being designated a new "signature research center" by the state Legislature.
In 2005, the state Legislature charged the Innovation Council with creating several new signature research centers by 2010 to translate research into commercial applications. The state's first signature research center, the Oregon Nanoscience and Microtechnologies Institute, was created in 2005 by the Innovation Council.
"We're looking at a wide range of opportunities, with a broad base of established work that is already contributing to the
"Certainly," Linton said, "the clean-energy area is an important one and will receive serious consideration."
