Six years ago, President Bush proposed to end our addiction to oil by building a hydrogen
economy. At the time, driving a hydrogen powered car didn’t seem that far off. But today, the
reality of mass produced hydrogen powered cars has hit some bumps in the road. Mark Brush
looks at the challenges ahead:

It’s all about the fuel cell. The cell converts hydrogen gas into electricity that can power up a
motor. And when that’s done – the only thing that comes out of the tail pipe is crystal, clean
water.

So there’s a lot of enthusiasm to build hydrogen powered cars. If you live in Southern California,
you can drive a hydrogen powered car right now.

(sound of a hydrogen car commercial)

But you can’t buy this car. You can only lease it. And you have to have a pretty good map.
There are only 2 places where you can fill the car up with hydrogen.

And that highlights just one of the challenges facing the hydrogen car right now. There’s no
infrastructure – no network of gas stations – to support it.

Steven Chu heads up the Obama Administration’s Department of Energy.

“It’s an infrastructure that is as extensive as the infrastructure for gasoline and diesel. And that
doesn’t come overnight.”

Chu wants to eliminate all the research money for hydrogen powered cars and trucks. He says
there are too many big problems to solve. There’s the infrastructure problem. Fuel cells are
expensive. The cheapest way to make hydrogen right now releases pollution. And there are
problems with storing the gas.

In an interview with MIT’s Technology Review, Energy Secretary Chu referred to these problems
as the four miracles. And that didn’t go over too well with some people.

“A miracle? Really? How many miracles have you seen? I’m not sure I’ve seen a real miracle in
my life.”

Levi Thompson directs the Hydrogen Energy Technology Laboratory at the University of
Michigan.

He says talking about these problems as miracles sends the wrong message. He admits, there
are some big puzzles to solve. But he’s convinced scientists can solve them.

“If you believe this is the savior, that this is going to transform the way we do things, I think you
have a responsibility to invest – even though that you see that it’s far behind.”

Thompson says the ultimate goal for a hydrogen economy is to get the hydrogen from water
using electricity from renewable resources like wind, solar, and hydro-power. So you get the
clean burning gas you’re looking for.

It can be done today, but it’s expensive. Thompson thinks it’ll get cheaper as alternative sources
of electricity become more widespread.

The Energy Department doesn’t want to give up on hydrogen research altogether. Secretary Chu
says fuel cells do make sense on a small scale – like to power fork lifts in a warehouse.

(sound of a warehouse and forklift)

Here at this Sysco warehouse in Grand Rapids, Michigan, a mini hydrogen experiment is
underway.

Sysco is a major food distributor. This warehouse is part of a year-long government funded
project. They’re running seventeen of their forklifts using hydrogen powered fuel cells made by a
company called Plug Power.

Darin VanDuyn is with Sysco. He says, mostly, they’ve had a good experience with these fuel
cells.

“We’ve had about 80 hours of lost time due to repair – minor failures, things like that – but nothing
major has disrupted their operation.”

VanDuyn says the company hasn’t decided yet whether they’ll move forward with the fuel cell
program. But policy makers say real-world experiments like these move us closer to mass
produced hydrogen vehicles.

Even though the Obama Administration wants to cut funding for hydrogen powered cars and
trucks, Congress holds the purse – and has the final say. So far, it looks like Congress will
continue to fully fund the research.

Automakers say the ups and downs of federal funding don’t affect their plans. Several
companies say they’ll start selling hydrogen powered cars in 6 to 8 years – and they’ll let the
market decide the fate of the hydrogen economy.

Researchers and start-up companies are looking for new ways to power the country. There’s been a lot of hope for hydrogen. But as Mark Brush reports there have been some bumps for companies on the road to the new hydrogen economy:

There has been a lot of excitement about hydrogen fuel cells for awhile now.

Ten years ago we talked to a rep at a company called Plug Power. He was excited about selling a dishwasher-sized fuel cells that could power and heat your home.

“The only barrier to fuel cells is that people don’t know about them.”

Turns out, that wasn’t the only barrier.

It’s expensive to make these things, and the units weren’t as efficient at heating as they hoped they would be.

But the company is still around, and they are still hopeful about fuel cells for your home.

Andy Marsh is the president of Plug Power.

“So the industry hasn’t moved ahead as rapidly as we would like. It sometimes takes many more years to makes some progress than you had originally hoped.”

Marsh says his company is selling fuel cells in places like India, but he says fuel cells for our homes in the US are probably still three to five years away.

Transcript

The Department of Energy wants to cut funding for the development of hydrogen powered vehicles. Mark Brush reports the Energy Secretary has decided that cars powered by hydrogen are too far off:

Six years ago, President George W. Bush proposed spending 1.2 billion dollars to develop hydrogen power cars.

Now, Stephen Chu, President Obama’s Energy Secretary, says hydrogen powered cars aren’t yet practical for today’s market.

Chu says they’d rather spend money on things like plug-in cars and cars powered by biofuels. Things that can hit the road now instead of 20 years from now.

People working on hydrogen powered vehicles aren’t too happy about the cuts.

Patrick Serfass is with the National Hydrogen Association.

“I’d say the hydrogen industry is perplexed. The administration has a lot of smart people in it and they have done a lot of great things for many parts of the renewable energy sector. But the proposal to eliminate the hydrogen vehicle program is a mistake.”

Serfass says hydrogen powered cars are not as far off as the Energy Secretary might think. He and his group are trying to persuade members of Congress to put research money back into the budget.

Scientists can produce hydrogen from water.
But the process is expensive. Julie Grant
reports on new science that has researchers
buzzing:

MIT researcher Daniel Nocera has found a cheaper way to get hydrogen
from water molecules. Researchers already have been able to do this – but
only with a precious metal – platinum. It costs nearly $2000 an ounce.

Nocera’s team discovered a material based on cobalt that does the same job.
Cobalt costs more like $2 an ounce.

James McCusker is an expert on solar energy conversion at Michigan State
University. He says the discovery has researchers excited.

“A, it works. But B, it works in such a way that it’s very, very easy to put
together. And it’s made of very inexpensive materials. They’re really
potential game changers in this field.”

McCusker says there’s still a lot of work left before we’re ready for a
hydrogen economy.

The new research was published in the journal Science.

Using Dams to Make Hydrogen

Across rural America, there are old dams and
millponds sitting unused. A century ago, they provided
vital hydro-power for local industry. But many of them
were shut down as big power companies offered more and
cheaper power. Now, one community wants to use its
hydro-dam to power a hydrogen making facility. Jacob

Across rural America, there are old dams and
millponds sitting unused. A century ago, they provided
vital hydro-power for local industry. But many of them
were shut down as big power companies offered more and
cheaper power. Now, one community wants to use its
hydro-dam to power a hydrogen making facility. Jacob
Resneck reports:

(rushing water noise)

We’re standing beside an old dam next to a public area still known as Power Station Park.

“Back in the 1800s, where we’re standing now was a sawmill.”

Mayor Jamie Rogers is the mayor of Lake Placid, New York.

Two dams on this river create Mill Pond.

“As you look to your left, that was the old turbine house. It was one of two
turbines in the community that generated power for the village.”

After the massive hydro development in the late 1950s, Lake Placid’s hydro-electric turbines were
removed in favor of cheaper imported power.

Now the village is working on a project to again harness this local energy source. But this time it won’t
be for conventional electricity.

“We’d be generating power to start electrolyzing water to create hydrogen.”

Electricity from the dam would be used to extract hydrogen from the water. The hydrogen would then
be stored in high pressure tanks. The fuel could be used to operate vehicles without emitting any
greenhouse gases.

The researcher behind the Lake Placid proposal is Richard Greeley. He’s a former professor who’s
worked on other cutting edge energy projects.

“You use air from the atmosphere on one side and hydrogen on the other and they combine on the
electrode and it forms water and electricity.”

Greeley’s founded a company called Aqua Green Electric Energy. He hopes to develop local sources
for powering hydrogen fuel cells.

“This turbine set up I have could fit on any dam. Why you can renew it and generate electric power again from any number of dams, big, small,
little – any size. So, I’m thinking this whole feature can be duplicated once we show everyone that this thing works.”

The project is expected to cost $1.5 million dollars. The Village of Lake Placid won’t spend local tax money,
but plans to try to get state and federal dollars to pay for the project.

It’s expected to take at least 18 months to build. If it is built, it’s believed to be the first of its kind in the
country.

This project won’t be a money maker. The amount of hydrogen that could be produced would be at
most, about 25 kilograms a day – the equivelant of about 25 gallons of gasoline.

Eventually, local production facilities could spring up all over the country. Daniel Sperling is director
of the Institute of Transportation Studies at the University of California, Davis. He says as the sun sets
on the era of cheap oil, the nation and the world will have to start making other arrangements.

“It’s becoming increasingly urgent to reduce the amount of oil we use and to reduce the amount of
greenhouse uses. And in both cases hydrogen has great potential. Many people think that in 30 or 40
years it will be the dominant fuel source for vehicles, and for other uses as well.”

A 1998 survey by the U.S. Department of Energy found 212 untapped sites with significant hydro-
electric potential. That’s in the state of New York alone.

Lake Placid Mayor Jamie Rogers says all that unused power could eventually add up, cutting total
greenhouse emissions.

“If you look at small dams like this across the Northeast, across this state and probably across this
country, there’s a lot of potential to generate hydrogen fuel on sites from existing dams that are already in place.”

And he hopes his town is the first to show that it can be done.

Ford Motor Company is rolling out a small fleet
of hydrogen powered shuttle buses in the US and Canada.
The company says its one small step toward a future
without oil. Dustin Dwyer reports:

Ford will have a total of 30 hydrogen powered shuttle buses spread around North America, from Florida to
Vancouver, British Columbia.

Most test projects with hydrogen vehicles these days involve a fuel cell. But Ford is using hydrogen to
power a mostly conventional internal combustion engine.

Ford says that means there’s less research to be done, and the buses could be mass produced
earlier.

But Ford’s John Lapetz says the problem is still: where would you fill it up?

“Realistically, you gotta look at the infrastructure to refuel these kind of vehicles, you gotta look at the public policies that go around those kinds
of things, because you’re talking about not a significant change in the vehicle, but a significant change in
the way the vehicle is received in the community.”

Another problem is cost. Ford says each of its hydrogen buses now cost 250 thousand dollars.

Company Turns Waste Juice Into Energy

Tiny single-celled organisms could become the giants of
energy production in the near future. Scientists are
using bacteria to convert waste into hydrogen energy.
Lisa Ann Pinkerton recently watched a vat of microbes
turning wastewater into electricity:


More than 17 million gallons of grape juice is sitting in what amounts to be a huge
refrigerator. It’s Welch’s grape juice ready to be bottled. About the size of a
gymnasium, the cooler’s covered with tile and the juice is stored in big
stainless steel tanks.


Paul Zorzie is the plant manager. He says they have to regularly clean the
tanks. And first they rinse them with water to clean out the remaining juice:


“Juice would be anywhere from 10 to 20 percent
sugar, so what goes down the drain might be .3.”


Since there’s still a little bit of grape juice and sugar in that wastewater, it can
still be used. Behind the plant, the faint smell of grape juice wafts from a
bubbling tank of wastewater. It looks kinda like a purple jacuzzi. In a nearby
shed, Gannon University Professor Rick Diz has built a pilot system to covert
the sugar in that grape juice wastewater into electricity. With the help of the
Ohio biotechnology firm NanoLogix, he’s coaxing millions of microorganisms
to consume the sugar and produce hydrogen:


“The sort of bacteria that produce hydrogen and
actually other bio fuels of one sort or another just
love sugar. Just like for people, sugar is the easiest
thing to digest for many organisms.”


Diz says if you keep introducing food that sugar from the watered-down grape
juice, the microbe population will double every 24-48 minutes. He’s trying to
keep the conditions just right to encourage hydrogen-producing microbes to
grow, while at the same time discouraging methane producing ones. They feed
on hydrogen, and it can be a careful balancing act.


When the microbes produce enough gas, the pressure trips a switch and the
hydrogen is pumped into a slender, high-pressure holding tank:


“And so far we’re been quite successful. We are in fact
producing hydrogen gas, we have used that gas to run an
engine that generated electricity for us on just a
demonstration purpose.”


You can imagine, there are all sorts of industries that create waste sugar
water, from fruit juices, and sodas to candy makers. So there’s lots of
potential to generate hydrogen and then electricity from residual sugar in
wastewater.


But, Diz says the Welch’s system is the only one in the US to successfully do
this outside a laboratory setting. The Welch’s plant in Erie, Pennsylvania
spends about one-and-a-half million dollars a year for electricity and
wastewater treatment each. It hopes a large-scale project that Diz will build
this spring can put a dent in those bills:


“Welch’s is certainly one of the first companies that we’ve hear of who’s expressed
interest in producing hydrogen from microorganisms.”


That’s Patrick Serfass at the National Hydrogen Association. He says
developing renewable ways to generate hydrogen is ideal for a greener energy
sector. But the methods have to be economically worth it:


“The trick is to make the leap from the laboratory to real world applications, and using the hydrogen to either produce
electricity or meet some other energy need.”


Serfass says if Welch’s makes good on it’s plans to built a large demonstration
bio reactor it’ll be a major step for renewable hydrogen and an example to the
rest of the nation’s over 200 beverage makers and bottlers.

Hydrogen: A Pollution Shell Game?

Lots of people in the automotive industry expect hydrogen to be a major
fuel source in the future. Cars that run on hydrogen don’t emit
greenhouse gases from the tailpipe. In fact, they don’t emit anything
except water. It might sound like magic, but there are some costs to
fueling the future on hydrogen. Julie Grant reports:

Lots of people in the automotive industry expect hydrogen to be a major
fuel source in the future. Cars that run on hydrogen don’t emit
greenhouse gases from the tailpipe. In fact, they don’t emit anything
except water. It might sound like magic, but there are some costs to
fueling the future on hydrogen. Julie Grant reports:


There are a lot of young guys checking out the hybrid cars on display at
this exhibit. Sales associate Chris Beckham is putting on his tie as
he walks over to the sleek, futuristic cars Honda hopes to lease to
consumers as soon as next year:


“It’s a fuel cell-powered vehicle. It runs on hydrogen. The only
emissions it has is water. So, it’s a really great vehicle for the
environment.”


Beckham hopes he gets a chance to lease one:


“What do you think, are you ready to drive one of these?”


“Absolutely. I can’t wait to get my hands on one of these. If you ever get thirsty,
just stand behind the car with a cup.”


Most cars available today, even those that run on alternative fuels,
still emit at least one kind of pollution: carbon dioxide.


David Robillard and his two sons are looking at cars at this exhibit.
He’s worked at Ford Motor Company for 36 years. He thinks hydrogen
will be the long-term energy solution because it doesn’t emit any pollution
from the tailpipe:


“All leaders in market going to try to be first in that segment, and I think
it’s going to be huge. I think 10-15 years from now, it’s going to be a
revolutionary mass transportation system that we have.”


That’s music to Steve Ellis’s ears. He’s Honda’s manager of fuel cell
marketing and says there’s a need to transition from an oil-based
transportation system to hydrogen. Ellis says hydrogen will be a
cleaner alternative:


“Only hydrogen offers the opportunity to have zero carbon emissions from
the vehicle – zero CO2 emisssions AND zero CO2 emissions from the
fuel.”


Ellis sees research and development of hydrogen cars as a noble goal.
But not everyone thinks hydrogen is going to be the climate change savior:


“From one standpoint, I think it’s great. From another standpoint, I
think we also need to check other options as well.”


Paul Erickson is a leader of hydrogen research at the University of
California at Davis. He’s director of the school’s Hydrogen Production
and Utilization lab
. Erickson remembers curling up on the couch as a kid, his lungs burning from all
the ozone pollution in southern California, and he wanted to clean up the
air. But he doesn’t think hydrogen is the best solution that’s
currently available:


“There may be other options that are not as say, politically saavy, but
are options that from a technological standpoint make a lot more
sense.”


It takes energy to create the hydrogen used to run a car. With today’s
technology, that energy is almost always natural gas, but it could be
any fossil fuel. Erickson says those cars don’t reduce energy use or
pollution:

“You’re taking, let’s say some fuel – that could be coal, that could be
any type of energy source – and you convert that energy into hydrogen
and you ship that to the user… it gives you a nice warm fuzzy feeling
saying I’m not part of the problem. But you know what? All you’re doing is
shifting that pollution upstream.”


Some engineers say that’s not necessarily a bad thing – that it would
be easier to control pollution coming from a few power plants than
from the millions of cars emitting greenhouse gases today. But Honda’s
Steve Ellis says hydrogen cars don’t create as much pollution as gas-powered vehicles. Even though nearly all of them need fossil fuels to
produce the hydrogen:


“Even with that method of doing it, we have over 50% reduction when you
factor in in wheel-to-well emissions compared with today’s gasoline cars.”


(Grant:) “50% cleaner?”


“50% CO2 reduction.”


Ellis says hydrogen can be made using renewable fuel sources such as
solar, ethanol, and methanol, but so far it’s not cost-effective. In
the meantime, Honda and other companies expect to start producing some
consumer model hydrogen cars that use fossil fuels in the next few
years.

Hydrogen Powers Family’s Car and Home

  • Mike Strizki demonstrates how a balloon filled with hydrogen can run a fuel cell and power an electric fan for about 45 minutes.

Many homeowners have reduced their fossil fuel consumption by placing solar panels on their rooftops. But one man has gone to a whole new level. He’s created a homemade power plant that runs on solar power and hydrogen fuel cells. Brad Linder reports:


Mike Strizki’s been tinkering with cars his whole life. Over time the 49-year old engineer became convinced that hydrogen fuel cell vehicles were the future of the auto industry. But during his 16 years with the New Jersey Department of Transportation, Strizki saw there was a problem with fuel cell cars: nobody was really building them.


“You had the auto makers and you had government pointing fingers. Well, you know, you build the fuel cell cars first and then we’ll provide the infrastructure. And they said, well you provide the infrastructure, and we’ll build the fuel cell cars. And I got tired of hearing that argument. And I said well, one way to solve the problem is to make your infrastructure your home.”


Five years and half a million dollars later, Strizki’s achieved his dream.


Here’s how it works. Strizki’s garage is covered with solar panels. They provide electricity for his house, and when there’s extra power, it’s routed to a device called an electrolizer, which breaks down water into hydrogen and oxygen.


During the summer, the hydrogen is stored in fuel tanks on Strizki’s property. And in the winter, he runs the hydrogen through a 6 kilowatt fuel cell to make energy. Strizki, his wife, and three children, are the first family in the country to live in a house powered entirely by hydrogen fuel cells and solar power.


And there’s another benefit: Strizki can fuel up his hydrogen fuel cell vehicles at a gas pump near his garage.


(Car accelerating sound on pavement)


“The fuel cells have enough to run the vehicle at about 50mph on fuel cells alone. If you’re going faster than that you’re sipping off the battery pack at a very low rate.”


Strizki helped design this car for Rutgers University 7 years ago. It’s been running ever since. Now that he has a fueling station at his home, he plans to convert his other car, a Toyota Prius, to run on hydrogen as well.


Strizki pulls up to the hydrogen fueling station – a series of converted propane tanks out by his garage. Opening his car’s trunk, Strizki connects a hose from those tanks to a smaller tank in the car.


“That’s how it refuels.”


Strizki’s system runs like a well oiled machine, only without the oil. But it wasn’t always so simple. When he first decided to build his home power plant, Strizki sought government approval from his home town of East Amwell New Jersey.


“I said all right, I’m doing this like anybody else who’s getting a building permit. I walked into the town and I said here, I want to build a solar hydrogen fuel cell home… and well, that… you know, the first place I went was the zoning officer, and he told me it’s an uncustomary use in a residential zone, and it’ll be a cold day in hell before I allow this.”


East Amwell Mayor Kurt Hoffman says the zoning officer was known as a stickler. The township had accidentally removed a line in a local zoning law allowing homeowners to use alternative energy.


“So we did an addendum to the zoning ordinance to allow alternative energy usages. These kinds of things, they have to be publicly noticed, you have to have public hearings. That brought out some people’s concern about hydrogen technology and the safety issue.


Hoffman says Strizki brought in a series of experts to testify that his house wasn’t going to blow up. The hydrogen was being stored at a safe pressure in the same type of tank normally used for propane.


Strizki says he’ll probably never make back the half-million dollars it costs to build his system. But he hopes to cut the costs by 90%, by mass producing and selling solar-hydrogen fuel cell systems to other homeowners. He says the future of the planet depends on renewable energy and not fossil fuels that have to be transported halfway across the world.


“At least the fact that I’m using the energy in the same place that I’ve created it, the energy is still zero carbon, and it’s still free, once you’ve paid for the equipment.


The Strizki’s don’t skimp on electricity. They have a big screen TV, a hot tub, and all modern appliances. And Strizki takes great pride in the fact that he can power everything, including his car, using renewable hydrogen power.


“There’s no shelf life, and that’s what powers the sun. When the sun stops shining, we’re all dead. So this is a much better solution than digging big holes in the ground, throwing sulfur up into the air. This is something that’s definitely sustainable. We just have to have the will to do it.”

Harnessing Energy From Food Scraps

Leftover broccoli, unfinished hamburgers, wilted salad… sounds like a stinky mess… but it also has the potential to generate electricity. A new power plant fired up this week and you won’t find any coal or natural gas fueling its generators. This plant is powered by leftovers. Tamara Keith reports:


The Biogas Energy Project on the University of California Davis campus is the first real-world demonstration of a new technology that could change the way we think about trash.


Food scraps from San Francisco restaurants are loaded into large sealed tanks where bacteria go to work, converting the food into fertilizer and releasing hydrogen and methane gas. That gas can then be used to fuel cars, or create energy using a generator.


Dave Konwinski is CEO of Onsite Power Systems Incorporated, which operates the plant.


“We’re burying all this organic waste in landfills, but every one ton has enough power to provide the heat for 10 homes, so the numbers are staggering how much energy we can make.”


Konwinski says he hopes to make the trash to power system commercially available early next year.
