President George Bush said yesterday that the key to keeping U.S. cattle and hog farmers from feeling the pinch from rising feed-corn prices is a breakthrough in cellulosic ethanol production technology.
Critics of the President’s energy policy say that Bush’s strategu of offsetting 35 billion gallons of gasoline use a year by 2017 with alternative fuels such as ethanol is unrealistic and could make feed-corn prices significantly more expensive.
Nonetheless, President Bush said he was confident in his goal, but it would require continued government funding. Cellulosic ethanol “is coming to fruition, and the role of the government is to stimulate thought and investment.”
The Bush administration has asked Congress for up to $4 billion in loans guarantees for biofuel projects, which would include plans to build biorefineries and cellulosic ethanol plants, which produce motor fuel from biomass such as wood chips, switchgrass, and corn stover.
The President says his 35 billion gallon goal is supposed to help cut U.S. dependence on foreign crude supplies and address climate change through cleaner-fuel. The Administration is aiming that 20 billion gallons will come from cellulosic ethanol, with only around 15 billion gallons likely to be supplied through corn-based ethanol due to market constraints.
Presently, however, it’s technically unfeasible to produce cellulosic ethanol commercially because of the high cost of enzymes that break down the corn starch into sugar for fermentation, and some energy analysts wonder if a breakthrough is possible within the timeline set by Bush.
“I know it sounds like a pipe dream to some…(but) we’re on the verge of some breakthroughs that will enable a pile of woodchips to become the raw materials for fuels that will be able to run your car” he added. If cellulosic ethanol doesn’t become commercially viable in time, the Buch administration is hoping to use coal-to-liquid production, another alternative fuel, to help meet the 35 billion gallon goal.
