The federal government is pushing the production of ethanol to help reduce our reliance on fossil fuels. Charlie Schlenker reports the expected boom in ethanol production may have a mixed environmental effect:


As the demand to produce more ethanol takes up more corn, agriculture experts predict prices will rise. Illinois State University Ecology Professor Roger Anderson says that will create an incentive for farmers to abandon the Conservation Reserve Program. The CRP pays farmers to keep environmentally fragile land out of production.


“They’re talking about expanding corn production for example, for ethanol by eight to ten million acres, and the only place they’re going to get it is to take this land out of CRP. And there will be a lot of pressure to do this.”


Anderson says planting corn on CRP acreage could increase erosion and reduce habitat diversity for wildlife, but an Agriculture Department Economist doubts there will be much pressure on CRP acreage.

This summer, drivers got a crash course in the dangers of fossil fuel. Gas prices shot above $3 a gallon, concerns about global warming surged, and instability continued to plague areas of the world where oil is produced. We’ll be taking a look at some of the technologies that could help the US kick its fossil fuel habit. We’re starting with an alternative fuel that’s been sprouting up in gas stations across the region. Dustin Dwyer has this look at the promise, and the limitations of ethanol:


This summer, Misty Childs found a way to do something positive about the fossil fuel problem. She says that she and her husband realized their Chevy Silverado pickup could run on E-85, a blend of 85 percent corn-based ethanol and 15 percent gasoline.


E85 burns cleaner than gas alone, so it’s good for the environment. And the ethanol is made from corn grown in the US. As she tops off her tank at a gas station, Childs says that makes a difference.


“It means a lot that we’re doing something for our country here, and not having to rely on others.”


Detroit’s Big Three automakers have been making a big push for E-85 in the last year. E-85-capable vehicles get the automakers a credit on federal fuel economy standards. So, even if drivers put regular gas in the vehicles instead of E-85, Detroit still gets a credit for doing better. And this summer, as more buyers became aware of the problem with fossil fuels, E-85 was just about the only alternative Detroit had to offer.


But ethanol as it’s currently made has limits. Jason Hill is a researcher at the University of Minnesota. He recently published a study on the long term outlook for corn-based ethanol.


“What we found is if you convert every corn kernel we produce in this nation to ethanol, we would be able to offset only about 12 percent of our national gasoline usage. So that’s not that large.”


That’s every corn kernel, including what we currently use for food. Which brings up another problem with ethanol: if E85 jumps in popularity, will that mean less corn for animal feed and grocery stores?


Maybe. Corn originally became popular because it was already being grown around much of the country, with help from federal subsidies. And ethanol processors, such as Archer Daniels Midland, also got tax breaks for making corn-based fuel.


But there’s another option for ethanol. Inside a lab at Michigan State University, researchers are working on the next generation of the fuel. This is what’s called cellulosic ethanol. Instead of using grains like corn kernels, cellulosic ethanol is made from the starches in plant cell walls. It can be made from pretty much anything that stands up straight – wood, prairie grasses and corn stalks.


That offers the possibility to increase the ethanol output for every acre of land devoted to the crops, and those crops don’t require fossil fuel-based fertilizer. They also don’t require planting every year by gas or diesel burning tractors the way corn does.


Professor Bruce Dale heads research into cellulosic ethanol at MSU. He says the current problem with cellulosic ethanol is finding a cheap way to break down the stiff materials. His lab uses ammonia to do the trick.


“The idea is to make cheap sugar. And the plant cell walls potentially could give you the cheapest sugar on the planet, if we could figure out how to get at that sugar easily. That’s what our ammonia process does in combination with the enzymes.”


It turns out that, much like a teenager eating pop-rocks, cars and trucks get a whole lot of energy from fuels based on sugar. Dale says most woody plants have plenty of sugar, but it’s really hard to get that sugar out.


Dale says some cellulosic ethanol could be on the market in the next few years, and the fuel could eventually sell for about 60 cents a gallon.


Right now, ethanol is still hard to find at the pumps. And one study says, even with major investment over the next decade, cellulosic ethanol might only equal half of our current oil useage by 2050.


That’s still a lot. But to really eliminate the need for gas, many experts say it’ll take more than just one technology.

States Slow to Pump Up Ethanol

  • As the price of gasoline rises, many states are looking for alternatives. One of those alternatives is the ethanol blend, E-85. But, some states (like Ohio) are not keeping up with the trend. (Photo by Lester Graham)

The federal government is focusing new attention on research and
development of ethanol. Some states – especially those in the corn belt –
are getting into the act too. The GLRC’s Karen Kasler reports:


Now that gasoline is near or above three dollars a gallon, ethanol seems
to be everywhere. The Renewable Fuels Association says more than a
third of the gasoline in the U.S is blended with ethanol, an alcohol based
fuel made with the sugar found in corn and other grains. A 10 percent
ethanol/gasoline blend can be used in every vehicle on the road, but
many politicians and consumers are very interested in the 85 percent
ethanol blend – E-85 – as an alternative fuel for cars and trucks. But
getting E-85 to drivers who have cars which can use it isn’t that easy.


Tadd Nicholson with the Ohio Corn Growers Association, says part of
the problem is the big oil companies have banned E-85 pumps under the
canopies at branded stations.


“Oil companies don’t own ethanol production. They own oil refining,
and so that’s their profit center and that’s where they get their fuel and so
they have a lot of control over that. They don’t own ethanol. I don’t
know why. They should, but they aren’t in the ethanol ownership
business yet. I say ‘yet’.”


The governors of Wisconsin and Minnesota have asked the big oil
companies to change their E-85 policy, and some states have been
encouraging independent gasoline dealers to put in E-85 pumps for a few
years.


But others, such as Ohio, have been lagging behind in the trend. Only
recently has Ohio launched a new energy action plan that sounds
ambitious, when it comes to providing access to ethanol to drivers.


LeeAnn Mizer is with the Ohio Department of Agriculture.


“The goal is to triple the amount of E-85 pumps available to Ohio
consumers by the end of 2006.”


That sounds like a lot – but it’s not, says Dwayne Seikman heads up the
Ohio Corn Growers Association.


“Tripling’s a nice start. There’s six… that would go to 18. But with over
150,000 vehicles in the state of Ohio, that’s not enough to cover the
effort.”


Since corn is Ohio’s top crop… it would seem to make sense. But unlike
other states in the corn belt, there are no ethanol plants in operation in
Ohio, though there are at least three under construction, and ethanol
supporters say the state is way behind its neighbors when it comes to
getting ethanol pumps at service stations.


Sam Spofforth is executive director of Clean Fuels Ohio.


“I’ll be honest, we’d like to see a lot more and we think a lot more is
certainly very possible. Indiana, they’re up to about 25 to 30 stations.
Illinois has over a hundred. Minnesota has almost 200 at this point.
Even places like Arizona are putting in E-85. They don’t make any corn
in Arizona. We think Ohio can do a lot more.”


Some critical studies have found that ethanol has a high energy cost with
low benefits – ethanol supporters say that’s been debunked. Whether
ethanol makes economic or ecological sense or not is still not certain.
But one thing is certain – cars using ethanol blends need to fill up more
than those using regular unleaded gasoline.


Robert White with the National Ethanol Vehicle Coalition says that’s
offset because typically ethanol-blended fuels cost less than regular
unleaded gas.


“Well, no doubt the fuel economy is the only negative with E-85, and we
tell folks that is where the price differential hopefully is there to make
E-85 use a wash.”


Part of the reason the price is lower is because the ethanol industry is
heavily subsidized by the government. Those lower costs would quickly
disappear if the subsidies were removed. Because ethanol is cleaner
burning, many support further development and use of the renewable
fuel.


General Motors is increasing the number of vehicles it produces that can
burn ethanol. Ford already produces E-85 burning cars and trucks.
However, many believe for ethanol production to be truly efficient,
farmers will have to start growing crops such as switch grass for ethanol
because corn requires too much fossil fuel based fertilizer and other
inputs to make it a permanent solution.
