If you’ve kicked the tires around
a new car lot recently, your dealer may
have told you about “flex fuel” cars. These
Flex Fuel Vehicles run on gas or they can
burn “E85” – a mix of ethanol and gasoline.
Congress promoted Flex Fuel Vehicles to cut
oil imports, but Shawn Allee reports
on why it really hasn’t helped:

I’m in my car across the street from a gas station. It’s raining right now. Keeping my
distance.

I’ve been watching a pump that dispenses that E85 blend – it’s the stuff with 85% ethanol.

Anyway, this is a very lonely gas pump. I’ve been here for something like an hour and
half and no one’s filled up on E85.

So, I’m gonna head in and talk to a manager to see whether this is normal.

(sound of bell)

Allee: “What’s your name sir?”

McLemen: “Greg McLemen.”

Allee: “How often do you see people fill up on E85?”

McLemen: “It depends on the location. Mostly people just don’t know what it is. They
see a little pump over there that says E85. A lot of vehicles take it, and they don’t even
know it.”

McLemen pulls out a flier that shows which vehicles can use E85.

He says lots of these models pull in, but often pass up his E85 pump.

(sound of crinkling)

McLemen: “You can see most of them are General Motors.”

Allee: “A lot of General Motors – Tahoe, Avalanche, Uplanders.”

McLemen: “We always recommend they go online or check the owner’s manual.”

But there’s something most Flex-Fuel owners manuals don’t tell you.

Nationwide, only about 1% of stations have an E85 pump.

E85 is supposed to cut gasoline use.

So it begs the questions: If there’s not much E85 around, why can so many Flex Fuel cars
use it?

“Currently, auto companies receive a fuel economy credit for producing a flex-fuel
vehicle.”

Environmentalist Roland Hwang tracks car policy for the Natural Resources Defense
Council.

He says the Flex Fuel incentives infuriate him – because they’ve made us waste gasoline,
not save it.

“Just very roughly speaking, like a twenty per mile gallon car might be treated like a
forty mile per gallon, almost like a hybrid-level of efficiency, under these fuel economy
credits. Thereby allowing the auto companies actually to build a less-efficient vehicle
fleet than they would have had to build.”

You don’t have to take Hwang’s word for it – energy analysts in the government agree the
incentives have wasted gasoline.

But some of these analysts say there is a bright side to the Flex Fuel vehicle incentives.

One is Paul Leiby of the Oak Ridge National Laboratory.

Leiby: “The important side of effect Flexible Fuel incentives is that we actually can begin
to achieve energy security with the enhanced capability to use alternative fuels even if
we’re not yet using them.”

Allee: “You mean the flex fuel vehicle program wastes some gas, but having flex fuel
vehicles around is like an insurance policy, for an oil shock or something?”

Leiby: “That’s exactly right. If we have to do something very fast, within one to three
years, we already have some vehicles on the road, that can quickly switch to ethanol.”

Leiby says Congress really believed this “insurance policy” idea, so it let Flex Fuel
vehicle incentives for automakers go on for more than a decade – even while we were
just spinning our wheels when it came to actually saving gas.

But now, the game could be changing.

Congress is phasing out Flex Fuel credits for the car makers.

And, there’s talk about making all cars flex fuel.

It’s a move Detroit doesn’t want to make. Because then they’ll have to actually have to
meet the government’s requirements of a more fuel efficient fleet.

Flex-Fuel Cars Often Burn Gas

  • The seven million or so Flex Fuel Vehicles are just a small portion of the 200-million or so vehicles in the American fleet, but there could many, more in the future. (Photo by Shawn Allee)

For most drivers, filling up at the
pump’s a pretty easy operation – you drive
up, you fill up, and you drive out. But people
who have Flex Fuel Vehicles have another choice.
They can fill up on gas or E-85, that 85 percent
ethanol blend – if they find the right station.
Shawn Allee reports a lot more of us
could have to make that same choice in the future:

For most drivers, filling up at the

They can fill up on gas or E-85, that 85 percent
ethanol blend – if they find the right station.
Shawn Allee reports a lot more of us
could have to make that same choice in the future:

I’m at a car lot in my home town. I’m not actually in the car market, but I am
curious what these E85 compatible Flex Fuel vehicles look like. I don’t own one
myself.

Anyway, I’m here with Edgar Moreno. He sells cars on this lot. He’s gonna show
me one of these vehicles here.

Allee: “Edgar, what can you show me?”

Moreno: “The Chevy Impala.”

Allee: “I actually don’t see anything that would tell me it’s a Flex-fuel vehicle.”

Moreno: “Usually it says on the gas cap whether you can use E85 or not.”

(sound of twist)

Allee: “It’s bright yellow. It says E85. In fact it says E85-slash-gasoline. What does
that mean?”

Moreno: “You can fill it with either, or.”

Allee: “How many stations are there available where I could fill this Impala up with
E85?”

Moreno: “I think there’s one in the area, but you have to drive quite a bit to get
there.”

Allee: “So, it’s one of those situations where, if I take this Impala off the lot, I could
still use it at a regular gas station, but I might have to search around for an E85
station?”

Moreno: “Yes, you do. Yep.”

Congress and both presidential candidates are considering making every car a Flex
Fuel Vehicle.

Detroit has spent a lot of money promoting E85 vehicles, and you might think they’d
be in favor of this.

Well, I called Ford Motor Company about this and found out that’s not the case.

“You could mandate every vehicle on the road to be a flex fuel vehicle. It would be a
great cost to our industry.”

Curt Magleby is Ford’s point-man on ethanol regulations.

He says if Congress gets its way there’d be more Flex Fuel Vehicles, but not necessarily
more E85 pumps.

“So you can mandate the vehicle side, but unless there’s a real focus on distribution,
it’s wasted money – we’d be putting dollars on the hoods of our vehicles for no
reason.”

So, Ford and the other car makers could make less profit on Flex Fuel Vehicles if there’s
a mandate.

At one time, they got government incentives to build Flex Fuel Vehicles, but those will
phase out.

So there’d be no benefit for the automakers.

And there’s another twist in the E-85 story.

The fuel industry is pushing to distribute ethanol in a way that might not require flex fuel
cars at all.

This is a little technical, but most gas already has 10% ethanol in it.

The fuel industry wants to sell 20% or even 30% ethanol blends because it saves oil
companies money. The government subsidized ethanol is cheaper than refining oil for
gasoline.

Ford and other car-makers are fighting this.

Magleby says burning E-20 or E-30 blends would be a disaster for existing cars.

“Ethanol is corrosive and it burns hotter, so you have to have a different fuel tank.
You have to have stainless steel fuel lines. You have to have hardened valves in your
engine.”

Car companies say burning 20% or 30% ethanol blends could hurt existing cars.

Scientists are checking whether that’s the case.

In the meantime, Congress is deciding exactly how it will promote ethanol.

It could mandate all cars be E85 Flex Fuel vehicles or it could promote lower-level
ethanol blends in gasoline.

Either way, over the next few years, we’re going to see big changes in our cars or our gas
pumps.

Growing Grass for Ethanol

The US is in the middle of an
ethanol revolution, or at least it’s
supposed to be. Scientists want to
develop ethanol that doesn’t use corn
– so food prices won’t go up. They’ve
found a tall grass called miscanthus that
can produce loads of ethanol – but they
haven’t perfected it yet. Shawn Allee reports some are trying to grow
miscanthus before the ethanol revolution
arrives:

You won’t find much miscanthus near Decatur, Illinois.

Nope. Corn is crop number one.

But all this corn-growing has a downside.

Agronomist Stephen John offers to show it to me.

Shawn Allee: “Where are we?”

Stephan John: “Well, we’re near the upper end of Lake Decatur, looking across at
the city’s dredge. Right now that dredge that is sucking up sediment from the lake
bottom.”

John says corn can leave ground bare, and rain washes dirt and fertilizer pollution into
this lake.

“Some of that nitrogen gets into streams and ditches into Lake Decatur, which had
to develop a facility to protect drinking water.”

John wants farmers to protect soil from erosion and use less fertilizer.

One option is to grow grasses that hold soil and use less nitrogen. One candidate is that
miscanthus grass the ethanol industry’s interested in.

Problem is, no one buys miscanthus yet.

“So, the trick is how do you make it economically viable to get those grasses onto the
land, how do you make that attractive?”

John says people are working on that problem.

Farmer Eric Rund stands near a patch of miscanthus grass. He’s a pretty tall guy, but the
grass is even taller.

Shawn Allee: “I’m putting my hand through here.”

Eric Rund: “It’s like a jungle in there, it’s like bamboo growth or something.”

Rund says corn farmers get kinda freaked out by miscanthus. It doesn’t grow from seed,
and unlike corn, it takes years to produce.

He says farmers need to experiment with it.

“And if we do that now, when ethanol production comes along, we will then have a
reliable source of biomass for the ethanol plant.”

Rund says some farmers would grow miscanthus just to protect water and soil. But to
make it mainstream, it’s gotta be profitable.

“That’s the key. No farmer’s going to plant much of it unless there’s a market for it
and there’s no market for it unless there’s a steady supply of it, so the two are going
to have to grow together.”

But what if that takes a while for the ethanol industry to come knocking? Who would use
Rund’s miscanthus?

I meet a guy who’s working on a solution.

Gary Letterly: “What would you like to do, where would you like to start?”

Shawn Allee: “I want to see your furnace.”

I’m with Gary Letterly. He works with the University of Illinois.

He says in corn country, some people heat their homes with corn pellets.
That gave him an idea on how to heat his office.

“And what you see here, it was a corn furnace, and we thought it would be just
great if we could use that furnace and burn grass pellets.

Right next to the modified furnace, there’s a plastic hopper full of miscanthus pellets.

They look like rabbit or hamster food, and they smell like grass.

“Look at high energy costs. This was very competitive with natural gas, and the very
nice thing is being able to keep this value very close to home. The grass was
produced within fifteen miles, the furnaces were produced within five miles, and the
grass was processed into a pellet within 30 miles.”

Letterly says miscanthus offers enough local economic and environmental benefits that
people should look into it now.

It already has potential to be a kind of super-star plant, with or without help from an
ethanol industry may never come.

It’s hard to be optimistic about
paying $4 a gallon at the pump.
But when you’re a teenager working on new
ways to make cheap fuel, it can be pretty
exciting. Julie Grant met one high school
student who is showing off his biodiesel
converter at the county fair:

(sounds of the fair)

The Fairgrounds sit in a quiet countryside of rolling green
hills. Small children yell and wave to family members as
they enter the Fair. There’s a steer auction in the barn. And
an antique tractor pull in the grandstand.
It’s like a scene is right out of a Norman Rockwell painting.

I’m here to talk with John Russell. He’s walking around in
faded wrangler jeans. A red t-shirt with the sleeves cut off.
And a ballcap advertising a tractor company.


“We’re at the Columbiana County Fair in Lisbon, Ohio. In
the junior fair building.”

John is 17 years old, and amidst 4-H project displays, he has
set up his view of the future. His homemade biodiesel
converter.

It’s a rectangular box – nearly as tall as me.
It’s made of stainless steel. There’s a row of toggle switches
along the side. They light up when John plugs it in. He’s
been working on this for more than a year, and says it
makes vegetable oil into a usable fuel.

“I started out with new oil from Save-A-Lot. I went down to
the local grocery store and picked up a bottle of frying oil.
And just from a recipe I found online, with methanol from an
auto parts store, they sell it as heat. It’s gasoline antifreeze.
Just methanol from an auto parts store, Caustic soda from a
hardware store, and oil from a grocery store, I set out to
make this fuel. And it took me couple of times. I finally got it
right when I actually tried a batch of waste vegetable oil from
the valley drive in. So that was my first successful batch.”

Last year, John was only able to fill a Gatorade bottle with
his fuel. Soon, he expects to convert 240 gallons of
vegetable oil into biodiesel in a day.

He hasn’t quite figured out how much the electricity costs to
run the thing, so he doesn’t know how much it’s costing him
to make the fuel.

Back five years ago, he met a guy who claimed to be making
biodiesel for 46 cents per gallon.

Headlines then were already screaming about skyrocketing
fuel prices. 1.60 per gallon. That’s what sparked John’s
interest in making his own converter.

“46 cents a gallon was pretty cool. And I’m into sustainable
agriculture. It’s recycling and its ecofriendly. The
culmination of all those things, that’s what makes it
interesting for me.”

Now that’s he’s almost 18, most of John’s friends are into
cars. And they’re taking an interest in his biodiesel project.

John Russell: “I’m a senior in high school. So most of my
friends’ reactions are ‘when are you going to give me free
fuel?’ But they all think it’s pretty sweet. It does make fuel a
lot cheaper than you could buy it at the pump.”

Julie Grant: “How much are you selling it for?”

John: “Well, I can’t sell it. Or else I’ll get in trouble with the
big man.”

Julie: “Is your dad the big man?”

John: “no. The IRS.”

He’s got to do some research into state and federal laws.
John wants to use the fuel to run his family’s tractors and
help heat homes in his neighborhood.

He’s not sure if biodiesel is the future of fuel, or even in his
long term future. But John is sure he wants a career in
green industry.

“Anything that’s gonna be tied into this fuel situation that
we’re faced with. Something’s gonna change and
something’s gonna change fast. So I’m very excited for
what’s going to happen.”

For now, John’s trying to put the finishing touches on his
converter so it’s ready for the Ohio state fair later this
summer. He’s the new face of agriculture – making eco-friendly practices into traditional American values.

From the Trash to the Tank

For the past few years, ethanol’s been
a political darling, but lately it seems the
party’s over. There’s concern the industry’s
using too much corn. That’s contributing to
rising food prices. Well, some companies want
to avoid the controversy. Reporter Shawn Allee explains they want to make ethanol from
stuff we leave behind at the dinner table:

To give you a sense of how touchy the ethanol issue’s gotten, consider what happened to Presidential
candidate Barack Obama. Last year, he supported mandates to add billions of gallons of ethanol to our
fuel stream. But recently, on ‘Meet the Press’, he was defensive.

“If it turns out, we got to make changes to our ethanol policy to help people get something
to eat, that’s the step we take. But I also believe ethanol has been an important
transitional tool for us to start dealing with our long-term energy crisis.”

Obama and other ethanol backers say we’re not stuck with corn-based ethanol. We can use wood chips
or energy crops like switchgrass.

But this cellulosic ethanol is a ways off.

First, the technology’s expensive. Plus, farmers don’t even grow energy crops now.

So, some companies hope to make ethanol from stuff that doesn’t need farms at all. It would come
from garbage cans, like this one at a coffee shop.

“In that receptacle there’s a lot of paper, and there’s some food bits and there’s some
scraps. So, we’re able to turn that into sugar. And the weak sugar, then we ferment, we distill into alcohol, and we get the ethanol.”

Zig Resiak is with a start-up company called Indiana Ethanol Power. He says garbage could compete
with corn.

“If you have a corn-to-ethanol facility, you’re going to pay for the feedstock. Trash, as a feedstock, we don’t
pay for it. The municipalities actually pay us to take the trash, just like a
landfill will take the trash.”

Resiak’s company isn’t the only one to figure this out. At least three other ethanol firms are asking
cities to hand over their trash, and cash. Besides being cheaper, there might be other advantages to
using garbage for ethanol.

Bob Dineen is with the industry group the Renewable Fuels Association.

“We have garbage all across the country.”

Here’s why that matters.

Before it makes it to the pump, ethanol needs to be blended at refineries. Dineens says those
refineries are far from corn farms and rural ethanol plants, but refineries are often close to big metro
areas, and big-city trash.

“A company that is able to produce from local landfill refuse – he’s clearly going to have an
advantage in terms of transportation, feedstock costs, and all the rest.”

Well, that’s the theory, anyway. The market hasn’t tested garbage-based ethanol yet.

So, what exactly is stopping companies like Indiana Ethanol Power from giving it a go?

Resiak says it’s simple – cities just haven’t been willing to part with their trash.

“Municipalities are very comfortable with putting it in the back of a truck and letting it go to the landfill. They don’t think about it twice. But for us to come in and say we’re going to
take it cheaper and we’re going to save you millions of dollars a year on your tipping fee – that’s different
and that’s kind of scary, and they want to take a good, strong look at that.”

Resiak predicts by the time cities do come around to the idea, there will be even more companies ready to
take garbage bags out of their hands.

Food Prices to Stay High

Food prices are expected to keep rising in the
coming year. That’s at least partly because farmers plan
to plant less corn. Dustin Dwyer reports:

Jim Hilker is an agricultural economist at Michigan State University. He says the
demand for corn is high right now.

“Ethanol’s probably the biggest driver of it, but there’s also been very strong corn
exports.”

Hilker says those exports are going to countries where the wheat crop has
come in lower than expected.

But with all the demand for corn, the U.S. Department of Agriculture says
farmers across the country are planning to plant about 8% less
corn this year, compared to last year. Last year farmers did plant more corn
than they had in more than 50 years. This year, corn production should still
be high, but it might not keep pace with demand.

Hilker says that could mean higher prices for food.

But he says there are a lot of other factors to consider when it comes to
food prices. He says gas is a big one, since food has to be transported.

Food prices are going up worldwide. A new survey
by the American Farm Bureau Federation finds supermarket
checkout costs have risen nearly 8% this year.
Julie Grant has more:

Retail food prices usually increase 3% per year. But over the last year the
cost of flour, cheese, bread, meat, oil, and produce is up – by more than
double the average.

The United Nations has predicted prices will stabilize in the long term. But
that consumers worldwide will face at least 10 more years of rapidly rising
food prices.

Commodity prices for corn, wheat, soybeans and other staples have been
skyrocketing over the past year – to more than double 2006 prices.
The higher costs are due in part to weather affecting crops, and growing
demand in China and India.

Economists also point toward the increased use of grains for ethanol and
other biofuels, putting pressure on food prices.

Biofuel Blends Fail Tests

In the US, the market for biodiesel was more
than 450 million gallons in 2007. But new research shows
not all biofuels are created equal. Lisa Ann Pinkerton
reports:

The American Chemical Society study tested 19 biodiesel samples
from states like California, Massachusetts, and Indiana. It found the
majority, almost 90%, didn’t meet federal requirements for B20 grade
fuel – 20% biodiesel, 80% petroleum. Some samples
contained as little as 2% biodiesel, while others exceeded the
20% limit.

One of the study’s authors is Christopher Reddy. He says biodiesel
above 20% could damage engines, while anything below 20%
reduces the environmental benefits.

“So perhaps the results of my small study will help people take a step back and
reevaluate things and put in some safe guards and such.”

Reddy’s says his study shows the blending inconsistencies found by
the National Renewable Energy Laboratory in 2004, still haven’t been
addressed.

Gao: Biofuel Distribution Problems

The federal government has no comprehensive plan to deal with an expected
increase in the production of biofuels. That’s according to a new study from
the Government Accountability Office. Dustin Dwyer reports that the lack of
a plan has some real consequences:


Mark Gaffigan studies energy issues for the GAO. He says there are real problems
getting biofuel capable vehicles where they need to be. For example, when officials at the Post Office tried to buy these so-called flex-fuel vehicles, the only options available were trucks with a larger engine than it needed. On top of that, officials had trouble getting biofuel, so they just ran the vehicles on gasoline.


“So, in effect, what you had was the government with vehicles using more fuel, using
more oil because they weren’t as efficient, when the intent was to try to encourage people
to use flex-fuel vehicles and use some of this ethanol to displace oil.”


The GAO says the Secretary of Energy needs to develop a new strategy that considers
both the production and distribution of biofuels.

A More Efficient Way to Make Ethanol?

The cost of oil is topping out near $70 a barrel and the nation is sending billions of dollars to unstable foreign countries to get it. With that in mind many Americans have begun to think about biofuels from domestic crops. Biofuels such as corn ethanol and soy diesel are the most popular right now, but researchers are looking into plants that don’t require the fertilizers and pesticides those crops need. The GLRC’s Richard Annal reports on one crop that could make ethanol much more efficiently:


(sound of pouring liquid)


Researcher Timothy Volk is showing me some liquid that is on its way to becoming biofuel.


“So what comes out of this is a brown liquid.”


This murky brownish substance contains sugars that have been extracted from wood chips. Separating sugars from organic materials is an essential part in the production of the biofuel ethanol, and a new method being developed at the School might revolutionize that process. This lab is at the School of Environmental Science and Forestry in Syracuse, part of the State University of New York system. Everybody just calls the school ESF. What makes the process at ESF different is the use of water instead of harsh chemicals as a means of extracting sugar and the use of wood from a type of willow as stock material.


The extracted sugars are then fermented and used to produce ethanol. Mix 85 percent ethanol with 15 percent gasoline and you’ve got E-85. Several models of cars can burn E-85. It burns cleaner than petroleum based products, and reduces the dependence on foreign oils.


ESF’s Timothy Volk says this method differs from others being used, creates several by- products, and leaves very little waste material.


“What’s left over still looks like a wood chip. That could go to the paper industry, and you could still make paper out of it, or you could use that wood chip to produce renewable heat and power. One of the beauties of this is that from a ton of hard wood chips from the forest or willow or where ever it comes from you’re making multiple products and there’s not a lot left.”


For stock material ESF researchers are experimenting with the use of the willow shrub tree. This plant is native and grows to over ten feet tall. The researchers say willow beats corn hands down. You have to burn fuel to plant corn every year. Corn requires fossil fuel-based fertilizers, and you only use the corn kernels rather than the whole plant to produce ethanol.


Jim Nokas is one of the lead researchers on the project. He sees the willow shrub as much more commercially viable than corn-based production.


“The best calculations we have for every unit of energy put into this process you get anywhere from 11 to 15 units of energy out. Compared to the best data available for corn, for every unit of energy put in, one would obtain 1.67 units of energy out.”


In other words, producing ethanol from willow is about ten times more efficient than using corn.


Tom Linberg is a commissioner with the New York State Department of Agriculture. Linberg says he’s excited by the prospect of wood-based ethanol production, and sees growing a low maintenance crop like willow as a way for farmers to earn extra cash.


“I think it’s something that could provide an option for a lot of farmers or land owners to use vacant land. Try and get some income off of it whereas they might otherwise not be getting income off the land. It’s a fairly low impact crop. You know, you plant it once and you don’t really need to do anything else with it, and this is something they could have on the side. Brings in some extra income and, again, helps keep that land productive.”


Willow can be harvested 6 to 7 times before replanting is necessary. It has a year long growing and harvesting season, and provides high yields. With about 2 million acres of dormant farmland in New York alone that could be dedicated to willow production, Volk believes growing willow for ethanol would have a positive effect on the local economy that buying foreign oil cannot offer.


“The real benefit here then is we build them here and it’s locally produced material, so you buy it from the land owners, or the farmers that are producing willow, the people that own wood lots. You buy all that material locally from the local community. You produce the ethanol and hopefully then we are using it locally in the community, and instead of sending energy dollars out of the state we cycle them around the local community and get lots of benefits associated with them.”


The researchers say the willow-to-ethanol process will be ready for commercial application within two years, and if it proves commercially viable the timing couldn’t be better. With ethanol plants being built across the nation, the wood method could become an efficient alternative to corn-based production in many states.
