The US government is spending
millions of dollars to build bio-energy
plants. They’ll turn everything from
wood chips to algae into energy. But
these facilities are years behind what
they are already doing in Europe –
especially in Germany. In the first
part of our three-part series on biofuels
in Europe, Sadie Babits takes us to one
German plant that makes green energy
on a massive scale:

We’re in Eastern Germany where crews work on what looks like brew vats.

(construction sound)

These monster tanks remind me of vats for brewing beer, except these vats will brew energy from fermenting rye, manure and bacteria.

“Basically, we’re standing here in front of the biogas and bio fertilizer production area. The big fermenter is for the biogas production.”

Oliver Lutke is our tour guide. He’s really a chemical engineer for Verbio. The company is one of Germany’s largest commercial producers of biofuels. Lutke’s been involved in turning this ethanol facility into a plant that makes ethanol and biogas. That’s methane.

“We convert everything into energy by using biological processes. This combination biogas and bioethanol production plant isn’t existing in the world.”

That’s what Verbio claims anyway. The company buys grain from some four-thousand farmers in the region. The grain gets turned into biogas and ethanol. Verbio then turns the minerals from making these biofuels into fertilizer.
That goes back to the farmers for their crops.

“We’re closing the loop to the farmer converting all the carbon to energy and the minerals going back to the farmers as fertilizer which is growing the plants used to extract the energy.”

Lutke says the company has the technology to make this industrial sized plant profitable. That baffles skeptics because it costs a lot to make green energy. You have to buy the grain. And the actual process of turning that grain into fuel can be really inefficient. By the time you’ve made one gallon of biofuel, that gallon of oil is cheaper.

Jan Liebetrau isn’t convinced Verbio has the answer. He researches bioenergy and its potential in Germany.

“If you put lots of energy into the system and you get bioethanol you’re putting more energy in than you get out.”

So making bio ethanol costs energy, which defeats the whole purpose of producing it in the first place. Lutke doesn’t see it that way. He says Verbio has the technology to make biofuels without losing energy. And because the company’s process is more efficient, Lutke says they’ve cut down on greenhouse gas emissions.

“We emit 200,000 tons and the plants we are using will eat off 180,000 tons and that’s a closed cycle.”

It’s not perfect, but there’s less greenhouse gas being released than, say, from an oil refinery. Lutke is convinced bio energy will play a big role in cutting greenhouse gas emissions.

Germany, and Europe for that matter, have become leaders on this. Germany wants to be the first industrialized nation to be powered entirely by renewable energy – a goal Germany could reach by 2050, well ahead of the U.S.

Bio-diesel is supposed to make

But to make enough biodiesel on
the cheap, we’ll need to get more
oil out of soybeans. Shawn Allee says we could be one step
closer to fixing that:

Tom Clemente is a kind of true-believer in biodiesel. He studies plant biology at the University of Nebraska. Clemente says the problem is, we use pricey soy-bean oil to make biodiesel.

“The downside is there’s just not enough of the oil to really make a dent on petroleum.”

Clemente figures scientists can manipulate genes inside soy beans to boost oil content, but no one knew exactly where the genes are. Recently, though, scientists completed a big-picture map of soy’s basic genetic make-up. Clemente hopes that’ll speed up development of oily soy beans – just for biodiesel.

“Really getting a bio-based sustainable fuel from some sort of cropping system, the production’s going to have be really up there.”

Clemente hopes we get enough biodiesel to clean up the nation’s dirtiest vehicles, such as construction equipment and city buses.

California regulators want car fuels to come from sources that create fewer greenhouse gas emissions. That means corn-based ethanol will soon get a kind of penalty in California’s fuel market.

Environmental groups like the Natural Resources Defense Council say ethanol should be at a disadvantage. The NRDC’s Roland Hwang says when we grow corn for fuel, farmers overseas plant more corn.

“Someone’s going to cut down a rain forest or convert pasture land or grass land to grow more food. Unfortunately, converting that land will lead to very dramatic increases in global warming pollution.”

Hwang wants the ethanol industry to stop using food crops for fuel.

Ethanol makers are not taking California’s rules sitting down, though; they’ve gone to court. They argue more lenient federal rules on ethanol should trump California’s.

say the homegrown biofuel is a good way
to move away from foreign oil. But a new
government report says many ethanol
refineries are putting a strain on another
natural resource – water. Mark Brush has
more:

When you fuel up at the pump, chances are you’re putting ethanol into your car. Nearly half of the gasoline in the U.S. is blended with ethanol. And that’s likely to increase as they build more refineries.

But the Government Accountability Office says these ethanol refineries should consider local water resources before they build. It can take a lot of water to make ethanol.

Anu Mittel follows water resource issues for the Government Accountability Office:

“Many of them are being built in areas where they are relying on groundwater aquifers for their water supply and that could have a devastating effect on the local community that is also relying on that same water source for all of its other needs.”

Refineries built in those areas often rely on irrigated corn to make ethanol. So it means drawing millions of gallons of water just to make the ethanol at the refinery.

And millions of gallons more to grown the corn.

industry might provide just a trickle:

The fuel industry’s supposed to create 100 million gallons of cellulosic-ethanol next
year. But industry leaders say they might create just 12 million gallons.

Wes Bolsen is with Coskata. His company can create ethanol from wood chips and even
household trash. Bolsen says companies like his found some investment money – but the
financial crisis created delays.

“We’re building refineries – 300, 400 million dollar assets and that’s a lot of money
to come together. We’re two years delayed, the whole industry. We can’t open them
in 2010. Facilities will start opening in 2012.”

The federal government might have to shift mandates for cellulosic ethanol into the
future.

That could mean the country uses less efficient ethanol from corn, or keeps using more
gasoline.

From the Trees to the Tank

Finding alternative fuel sources in our country involves looking at what nature has to
offer. In the West, they’re harnessing wind and solar energy. In the Heartland, it’s sweet
crops like corn. Susan Mittleman reports, in the South, they’re looking to their forests to

Finding alternative fuel sources in our country involves looking at what nature has to
offer. In the West, they’re harnessing wind and solar energy. In the Heartland, it’s sweet
crops like corn. Susan Mittleman reports, in the South, they’re looking to their forests to
make cleaner, greener fuels:

Chuck Leavell plays keyboards for the Rolling Stones. But when he’s not on the road, he
spends his time on his plantation outside of Macon, Georgia, tending to some 2500 acres
of pine trees.

“This is our tree farm here.”

From this tranquil refuge of nature and wildlife, he sees these trees as a possible way to
reduce our dependency on foreign oil.

“The fact that we have such wonderful resources, our forest, and that we are
looking for new markets, gives us a lot of hope to be able to use our trees to make
energy products, whether its electricity or gasification processes or any matter of
liquid fuels.”

Cutting down trees and turning them into fuels might not seem like the greenest thing to
do.

But people like Jill Stuckey, insist it is.

Stuckey heads Georgia’s Innovative Center for Energy, and says there’s no better source
for clean fuel here, than the state’s 24-million acres of forest land.

“We grow pine trees like Iowa grows corn. And it’s a renewable source of energy.”

Stuckey says trees grow faster and are more accessible in Georgia than any place else in
the country.

“It’s a good thing. Because trees sequester carbon. And we harvest these trees and
plant new trees, so we’re continuously replenishing our supply.”

She says an acre of pine trees can yield about seven tons of biomass per year.

Biomass is basically any living thing that grows and then can be harvested.
And that stuff can be used to make ethanol, electricity, and bio-diesel.

(sound of a factory)

At a small factory down in Albany Georgia, that’s what John Tharpe is making here.

Tharpe is semi- retired electrical engineer, and has designed a machine that converts
pine-tree chips into bio-diesel. The fuel can be burned to power and heat homes and
businesses.

“We’re using biomass. We make an oil and a char and then we are also looking now
at making electrical energy. You can use it in any commercial burner, such as
steam, boilers, those types of things.”

He’s already begun selling his biodiesel technology to people around the world.

So, Tharpe is making for electricity and heat. Other companies are making plans to use
trees to run our cars.

Range Fuels is building the ‘first-of-its kind’ bio-fuels plant in Soperton Georgia – which
will convert wood chips into green transportation fuels, things like ethanol and methanol.

Ron Barmore is the company’s project development director.
He says their facility is designed to produce upward of 100-million gallons of fuel a year.

“Our belief is that we’ll be able to compete with fossil fuels, with oil prices in the 70-
80 dollar a barrel range. We think long term that’s a viable place to be.”

And long-term sustainability is what tree farmers and environmentalists like Chuck
Leavell are looking for, not just for green energy, but for other reasons as well.

“These trees, in the period we plant them and their growing, they’re cleaning our
air, our water, providing home and shelter for wildlife, that helps everyone.”

More than 100 companies are looking at ways to use Georgia’s trees, in some form or
another, to produce greener, cleaner energy.

Eleven Northeastern states are working together to create a new fuel standard that will mean lower greenhouse gases.
Julie Grant reports that means, when you fill up your car in those states, the gas won’t be quite as bad for the environment:

The partnering states want to reduce the amount greenhouse gases coming from car tailpipes.

Ian Bowles is Secretary of Energy with the Massachusetts Department of Environmental Protection.

He says the states would prefer that the federal government take the lead on this issue, but they’re doing what they can to limit carbon emissions from cars and trucks as soon as possible.

“If everyone waits and sits on their hands until there’s a global agreement, it’s going to take a long time to get anything done.”

Bowles expects the eleven-state agreement to spur investment into new types of ethanol and biofuels. And he says that will mean new jobs in science, engineering, and at fuel refineries.

“We’ll be creating a much bigger market for biofuels. Jobs will get created and greenhouse gasses will be cut.”

The states expect to have a legally binding agreement on the low carbon fuel standard by the end of the year.

Green Fuel From Green Slime

When people talk about bio-fuels,

fuel from soybeans. But there are lots of
possibilities. One of them is algae. Algae
contains a lot of oil. The US Department of

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.
