Bush gets a whiff of biofuel
President Bush, who frequently jokes about his undistinguished record as a history major at Yale, is devoting considerable time these days to matters scientific.
Four weeks ago, he toured a chemical plant in Delaware. Earlier this month he visited a Virginia computer-chip manufacturer. On Wednesday, at a hospital in Tennessee, he watched a video of a surgical robot excising cancerous tissue, prompting his host to ask, “You OK with the blood?”
And Thursday, he studied what it would take to put cellulosic ethanol in your fuel tank. It’s made when enzymes or bacteria break down agricultural waste, switch grass, wood chips and other forms of biomass. Scientists hope the process that turns plants into a burnable liquid can be harnessed to economically produce at least a partial substitute for fossil fuels.
The president has been talking about this technology for more than a year and has made it a centerpiece of his 2007 domestic policy agenda, built around proposals to reduce U.S. gasoline consumption by 20% in 10 years by developing renewable and alternative fuels and increasing reliance on nuclear energy.
His proposals would require drivers to use 35 billion gallons of alternative fuels by 2017, up from the current 5 billion gallons. It would be a key to trimming U.S. reliance on foreign oil, which Bush sees as a national security liability, and to reducing carbon emissions, which are released when oil products are burned and are blamed by most scientists as a factor in global warming.
“I know it sounds like a pipe dream to some -- you know, there goes the optimistic president talking again,” said Bush, describing himself as having been “just a history major.”
But the scientists alongside him during his visit to Novozymes North America Inc. “are providing the brainpower necessary to help plants like this develop technologies that will enable us to convert wood chips into fuels that are running automobiles,” he said.
Bush toured the laboratories and factory where enzymes are produced and used to quicken the transformation of plant starch into fermentable sugars, a key step in producing ethanol.
The Union of Concerned Scientists, a nonprofit organization that focuses on environmental and other issues and often disagrees with Bush, said its analysis indicated that if Bush’s energy goals were met primarily by using ethanol, global warming pollution could be reduced by 160 million metric tons in 2017 -- an amount it likened to taking nearly 24 million current-model cars and trucks off the roads.
In recent weeks, Bush has made stops across the country in an effort to put the media spotlight on his domestic policies -- he discussed environmental issues in Shenandoah National Park in Virginia and his healthcare proposals in Tennessee, for example -- instead of the increasingly unpopular war in Iraq. Here in North Carolina, he spent about an hour and a half immersed in the efforts to expand the use of biofuels.
Specifically, Bush focused on the potential, still under development, to use enzymes to help convert such agricultural waste as cornhusks and weed-like switch grass into cellulosic ethanol, rather than increasing the demand for corn.
“The demand for corn, because of agricultural use and now energy use, is causing corn prices to go up,” he said, noting that hog farmers and cattle ranchers -- both of whom use corn as feedstock -- were feeling the pinch. “The question is, how do you achieve your goal of less dependence on oil without breaking ... the people dependent on corn?”
The answer, he said, is the technology being developed at companies like Novozymes.
On his tour of the facilities, Bush said the fermentation smell and steel vats reminded him of a distillery.
As he held up a beaker of ethanol and sniffed it, he said with a laugh, “I quit drinking in 1986" -- and then added: “Someday you’re going to be able to use this in your car.”
