Ethanol grabs attention of White House, Wall Street, automakers

by LIBBY QUAID, AP Food and Farm Writer

COON RAPIDS, Iowa (AP), Jun 03 _ A tractor trailer rig rumbles into the Tall Corn Ethanol plant. Corn pours from openings in its belly to bins underground, where conveyor belts and buckets haul it to gleaming steel silos rising 13 stories above the Iowa plains.

The 40-acre (16-hectare) distillery turns corn into alcohol in quantities that would make a moonshiner drool. Instead of white lightnin', the brew is converted to ethanol, a fuel that makes money for farmers and is seen as a possible solution to today's high oil and gas prices.

Like the other modern-day stills dotting the Midwestern landscape, the Coon Rapids plant reached capacity soon after opening _ within 12 days, to be precise.

Ethanol production in the United States is growing so quickly that for the first time, farmers expect to sell as much corn this year to ethanol plants as they do overseas.

"It's the most stunning development in agricultural markets today _ I can't think of anything else quite like this," says Keith Collins, the U.S. Agriculture Department's chief economist.

The amount of corn used for ethanol, estimated at 2.15 billion bushels this year, would amount to about 20 percent of the nation's entire crop, according to department projections.

Even as ethanol devours corn and pushes prices higher, President George W. Bush and the U.S. Congress are calling for even greater ethanol use. Wall Street cannot seem to get enough of ethanol-related investments. Automakers are speeding ethanol-capable vehicles onto the road.

Yet the ethanol industry is not without its critics, who question whether tax incentives provided by Congress are really needed.

The enthusiasm for ethanol makes farmer Lynn Phillips want to grow more corn. Phillips helped raise the money for the farmer-owned Tall Corn plant, which opened in 2002 as a way to make more money by processing every kernel of locally grown corn.

"We saw train cars after train cars of raw material being shipped away and value being added somewhere else," said Phillips. Now, the corn "is still going out on train cars _ it's just going out in the form of ethanol and distillers' grain."

Corn can cost more to grow because it needs heavy applications of fertilizer. Right now, Phillips plants corn on about half his 2,000 acres (800 hectares) and soybeans on the rest.

Inside the ethanol plant, corn is ground and mixed with water to make mash. It is heated and mixed with enzymes to convert starch into sugar and fermented with yeast to make alcohol _ just like making moonshine. Hanging in the air around the 500,000-gallon (1.9 million liters) fermenting tanks is the smell of sweet, white wine.

The mixture is kept just below 90 degrees Fahrenheit (32 Celsius). Yeast seem happier below that temperature, general manager Owen Shunkwiler hollers over the hum. Shunkwiler works for South Dakota-based Broin Companies, which invested in Tall Corn and is responsible for its operations.

After fermentation, the mixture is boiled to remove water, then dehydrated to boost the alcohol content. Before leaving the plant, a denaturant, or poison, is added to make the alcohol unfit for drinking. Then the ethanol is ready for shipping to fuel storage terminals that will blend it with gasoline as it goes into trucks for distribution to gas stations.

Also yielded in the process is livestock feed. Corn kernels minus the starch are left over _ think South Beach for cows. Every 56-pound (25-kilogram) bushel makes about 17.4 pounds (7.8 kilograms) of grain feed, according to the Agriculture Department.

Tall Corn produces 150,000 gallons (567,795 liters) of ethanol each day, enough to power an estimated 272 cars for an entire year if they ran on ethanol alone.

But automobiles do not run on pure ethanol. Instead, ethanol is combined with unleaded gasoline to boost its octane rating and reduce emissions.

The most common blends are 10 percent ethanol, approved for any make or model sold in the U.S., or 85 percent ethanol, known as E-85 and used in specially made flexible fuel vehicles. About 5 million vehicles in the U.S. can run on E-85; more are in production.

In Iowa in April, regular unleaded gasoline was selling for $2.71 per gallon (euro0.60 per liter), E-10 for $2.65 per gallon (euro0.55 per liter) and E-85 for $2.33 per gallon (euro0.48 per liter).

With demand comes expansion. In Iowa alone, three new ethanol plants opened last month. The industry likely will outpace a mandate from Congress to pump out 7.5 billion gallons (28.4 billion liters) a year by 2012, according to Collins.

Meanwhile, lawmakers envision vastly more ethanol in the nation's automobiles. Sens. Tom Harkin of Iowa and Richard Lugar of Indiana, are pushing to require 60 billion gallons (227 billion liters) of ethanol and soy-based biodiesel by 2030.

An expansion that big would require sources for ethanol besides corn. Ethanol is made from sugar cane in Brazil, which meets about half its fuel demand with ethanol. Sorghum, another feed grain, accounts for about 3 percent of U.S. ethanol, according to the Agriculture Department.

Research is under way on other potential sources, such wood fibers and residue from crop harvesting.

The big question is whether oil and gas will remain expensive.

"When the price of anything gets high enough, then all kinds of substitutes come out of the closet," Collins said. "That's what's going on now. As long as the price of oil stays high, where ethanol is profitable, this industry is going to keep growing."
