E-85: The Loneliest Pump

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.

Cellulosic Ethanol Breaks Ground

Getting fuel from plants like corn
and sugar cane is not that efficient. That’s
why researchers are working on so-called
cellulosic biofuels. The process turns things
like corn stalks, wood chips, and grasses into
fuel. As Mark Brush reports, some new
cellulosic refineries are breaking ground:

The new refineries are being built with money from the federal government. The hope is
to perfect a fuel source that a) doesn’t come from food, and b) is much more efficient
than corn-based ethanol.

The problem is it’s hard to get at the sugars inside the
plants. But the payback could be big. For every one unit of energy going in,
cellulosic ethanol could spit out about five to ten units of energy.

Brian Davidson is with the BioEnergy Science Center. He says industry officials are
hopeful, but he thinks these new refineries are just a first step.

“They believe that those technologies will be more widely applicable, but I actually
believe that we’re going to need further technology improvements to go from these first
few handful of plants, handful of bio-refineries, to make them widespread.”

Davidson says scientists still have not perfected ways to break down the plants in a
cost-effective way.

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.

High School Student Is Biofuel Whiz-Kid

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.

Potato Forks Better Than Plastic?

Biodegradable silverware has
popped-up in local coffee shops, fast
food joints, and even the Olympics.
But how eco-friendly are biodegradable
utensils? Kyle Norris has this report:

Companies are making disposable utensils from things like corn,
potatoes, and sugarcane. And many brands label their silverware as
biodegradable.

Sarah Burkhalter is a news producer with the environmental
journalism website, Grist.org. She says making silverware from
materials other than plastic is a step in the right direction.

“But I think that the encouragement should not be for people to feel
like they can use a fork for three minutes then toss it in the compost
and be done with it. I think the emphasis needs to be on reusing your
silverware. Whether that be metal or plastic or corn.”

Burkhalter says the other tricky part is that you need to read the
manufacturer’s instructions. She says many of these utensils are only
biodegradable in special composting facilities.

Which means the utensils will not biodegrade if you toss them into a
backyard composting bin.

For many people, the summer road
trip includes trips to the beach, and of

Two college students are driving across the

station this summer, they pull up to the
grease traps. They say it’s a way to raise
awareness about alternative fuels, and save
a bit of money. Katie Carey brings us this
audio postcard:

MATT: My name is Matthew Rolen Stucky. I am taking this ’85 Mercedes Benz Diesel
with a grease car kit, putting old vegetable oil that we find from restaurants along the way
and sticking it in and making it go.

DEVIN: Hi, I’m Devin and we’re getting our fuel for the car from mainly restaurants
from the deep fryer. They dispose of the grease and we just take that and filter it a couple
times.

MATT: Well I pre-filter it – it’s basically a water filter. I have a couple mesh filters that
it goes through and then it goes through a second gas tank where it heats up and runs
through the car and then has one more engine filter that it goes through secondary. You
can drive this around everyday nearly in every situation and it doesn’t slow down your
gas mileage you have the same top speeds, the same acceleration, literally you will not be
able to tell the difference, until you realize you’re not buying the gas, and then you are
happy about it.

DEVIN: We have a journal in the car and we have a tally of how many hummers we’ve
seen on the road trip so far and I think the tally is to sixteen, and we kind of do a little
‘ha-ha’ every time we see one. Just because we know how much they are spending on
gas.

MATT: The reactions range from people saying, “Oh yeah, you are putting it in your car,
great, yeah here take it.” To people going “You do what? What does it do in your car?”
And they don’t believe it and they want to go see it sometimes.

DEVIN: Some people this is the first grease car they have ever seen and they just think it
is awesome that someone is out there doing it. It’s not a solution for everyone, again,
there’s not going to be waste vegetable oil for every single person that wants to drive in
the car around the country, so it definitely is not a solution to the fuel crisis. It’s just us
trying to do our part to raise awareness.

From the Trash to the Tank

  • Ethanol can be made from material that would end up in a landfill (Source: Patrick-br at Wikimedia Commons)

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

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.

When people talk about bio-fuels,
they usually mean ethanol from corn or diesel
fuel from soybeans. But there are lots of
possibilities. One of them is algae. Algae
contains a lot of oil. The US Department of
Energy experimented with algae for nearly
twenty years after the oil crisis of the 1970s.
But with fuel prices so high, scientists around
the world are looking at algae again. Stephanie
Hemphill reports one researcher thinks
he’s figured out how to grow lots of algae, fast:

Roger Ruan has been trying for years to figure out how to turn algae into diesel,
economically. He’s the director of the Center for BioRefining at the University of
Minnesota.

Ruan says there’s no question it can be done; some people are already producing algae
oil. They’re growing it in open ponds. It’s used for pharmaceuticals, food supplements,
and cosmetics.

“Right now, based on an open pond system, per acre per year, you can easily get 5,000
gallons of oil, and soybean would probably give you 50. That’s 100 times difference.”

So algae can be far more efficient at producing diesel fuel than soybeans. But how do
you grow enough algae to make a dent in the nation’s energy demand?

Ruan is turning to an unlikely partner: the local sewage treatment plant.

“Wastewater has lot of nutrients: phosphorus, nitrogen, are all available in wastewater,
and actually you spend lot of money to remove these from wastewater, so if we can kill
two birds with one stone, that would be the best, and that’s what we’re hoping to do.”

(sound of treatment plant)

St. Paul, Minnesota’s sewage treatment plant sits on the bank of the Mississippi River.
The basement of the building where the solids are separated from the liquids is a
brightly lit space. It’s filled with big steel pipes and valves and tanks.

Off to one side, Ruan’s team is setting up a rack of aquariums – the future home of juicy
green algae. When everything is ready, some of the partially-treated waste will be
diverted into the tanks, where it will feed the algae.

The waste is still full of stuff that’s bad for the river, but good for algae.

“It’s got a fair amount of phosphorus, and some ammonia nitrogen that the algae are
going to need.”

Bob Polta is manager of research and development at the treatment plant.

It’s easy to see why he likes this idea: every day the facility has to remove 4 tons of
phosphorus and more than 16 tons of nitrogen from the waste stream.

The algae experiment, if it works, will allow them to do some of that removal in a more
cost-effective way. And this could be the answer to Roger Ruan’s problem of trying to
create enough algae to make enough oil to compete with petroleum diesel.

Polta says there’s a big potential, both for cleaning wastewater and for producing
energy in the same place.

“All the wastewater treatment ponds in the small communities around the state are
essentially using algae to treat wastewater; it’s just that they’re not being harvested. It’s
just that we’re getting two goals together here, and two research groups, one is essentially taking algae and
harvesting the oil and making biodiesel, and the other is using algae as a treatment
scheme, and to see if we can make this thing really fit.”

Polta expects by the end of the year he’ll know more about whether this is a practical
idea.

Roger Ruan says within six-to-ten years someone, somewhere, will be producing diesel
from algae on a commercial scale.
