Researchers are looking at ways to use corn-based ethanol as a way to power hydrogen fuel cells.
It would appear to be an environmentally friendly way to get into the hydrogen fuel economy.
However, ethanol might not be as environmentally friendly as its proponents claim. Back by the
farm lobby and ag industry such as Archer Daniels Midland, ethanol has plenty of political
support. But some researchers say corn-based ethanol is a boondoggle. The Great Lakes Radio
Consortium’s Mary Stucky reports…


This reactor is in a laboratory at the University of Minnesota ticking as it converts ethanol into
hydrogen. Researchers here envision thousands of these inexpensive reactors in communities
across America using ethanol to create hydrogen, which would then be used in fuel cells to
generate electricity.


Lanny Schmidt, a Professor of Chemical Engineering, directs the team that created the reactor.


“We’re not claiming our process is the cure-all for the energy crisis or anything like that. But it’s
a potential step along the way. It makes a suggestion of a possible way to go.”


Hydrogen is usually extracted from fossil fuels in dirtier and more costly refineries.


Schmidt says it’s much better to make hydrogen from ethanol.


“It right now looks like probably the most promising liquid non-toxic energy carrier we can think
of if you want renewable fuels.”


Not so fast, says David Pimentel, an agricultural scientist at Cornell University. For years,
Pimentel has warned about what he calls the cost and efficiency and boondoggle of ethanol.
Pimentel says ethanol is a losing proposition.


“It takes 30-percent more energy, including oil and natural gas, primary those two resources to
produce ethanol. That means importing both oil and natural gas because we do not have a
sufficient amount of either one.”


Pimentel says most research on ethanol fails to account for all the energy needed to make the fuel,
such as energy used to make the tractors and irrigate crops. Adding insult to injury, says
Pimentel, ethanol relies on huge government subsidies going to farmers and agri-business.


“If ethanol is such a great fuel source, why are we subsidizing it with 2-billion dollars annually?
There’s big money, as you well know, and there’s politics involved. And the big money is leaking
some of that 2-billion dollars in subsidies to the politicians and good science, sound science,
cannot compete with big money and politics.”


Pimentel also points to environmental damage of growing corn – soil erosion, water pollution
from nitrogen fertilizer and air pollution associated with facilities that make ethanol. But
Pimentel has his detractors.


David Morris runs the Institute for Local Self Reliance in Minneapolis. Morris is not a scientist,
but he commissioned a study on ethanol. He says Pimentel relies on out-of-date figures and fails
to account for the fact that ethanol production is getting more efficient.


Morris’ findings – a gallon of ethanol contains more than twice the energy needed to produce it.
As for subsidies…


“There’s no doubt that if we did not provide a subsidy for ethanol it would not be competitive
with gasoline. But what we need to understand is that we also subsidize gasoline, and if you took
the percentage of the Pentagon budget, which is spent directly on maintaining access to Middle-
Eastern oil, and impose that at the pump, it would add 25- to 50-cents a gallon. At that point,
ethanol is competitive, under the assumption that you will not need a large military budget to
protect our access to Iowa corn.”


But more efficient than making ethanol from corn might be grass, or even weeds. David Morris
says that’s because you don’t have fertilize or irrigate those kinds of plants, the way you do corn.


“So if we’re talking about ethanol as a primary fuel to truly displace gasoline, we have to talk
about a more abundant feedstock. So instead of the corn kernel, it become the corn stock, or it
becomes fast-growing grasses, or it becomes trees, or sawdust or organic garbage. And then
you’re really talking about a carbohydrate economy.”


Pimentel scoffs at that idea.


“You’ve got the grind that material up, and then to release the sugars, you’ve got to use an acid,
and the yield is not as high. In fact, it would be 60-percent more energy using wood or grass
materials.”


While scientists and policy people debate whether ethanol is efficient or not, Lanny Schmidt and
his team soldier on in the lab undeterred in their efforts to use ethanol for fuel. Schmidt
understands some of Pimentels’s concerns, but he thinks scientists will find an answer, so ethanol
can be used efficiency enough to help power the new hydrogen economy.

Fuel Cell Generator Gets Mixed Reviews

A Midwest Company is producing a generator it says will revolutionize the way large electric
consumers get power. While the company is hailing the generator as the next big thing, it is getting
mixed reviews from industry analysts and environmentalists. The Great Lakes Radio Consortium’s
Jonathan Ahl reports:


(sound OF the fuel cell)


Engineer Steve Brown is showing off a generator that can be the primary power source for an entire
hospital, prison, factory complex, or any other multi building facility. It’s a 250-kilowatt fuel cell
generator that’s as big as a one-car garage. It’s currently running at Caterpillar’s Research Center
just outside of Peoria, Illinois. The generator works by extracting the hydrogen from natural gas
and converting it into electricity. Brown says the only emissions from the unit are heat, water, and
carbon dioxide. He says the unit can also use that heat for other purposes, making a generator that
is up to ninety percent efficient:


“That means ninety percent of the heat, the potential heat in the natural gas has been converted into
useful energy and only ten percent is exhausted to the atmosphere. That’s sexy. It is, compared to
the typical internal combustion engine is in the high teens. And all the rest goes to waste and just
heats up the atmosphere.”


Brown says this unit can eliminate large electric consumers’ need to be hooked up to the power
grid. Peoria, Illinois based Caterpillar and Danbury, Connecticut based Fuel Cell Energy
Incorporated are manufacturing the generators. They say there is a growing market for reliable
power. They also say the generators are better for the environment than coal or oil fired power
plants. John Leitman is the president of Fuel Cell Energy:


“The fuel cell here generates electricity just like a large battery, except with a fuel cell, you can keep
feeding it fuel and air and it will keep generating electricity, very cleanly.”


Leitman says the generator will also be easily convertible to a pure hydrogen power generation unit
if that technology becomes available. But some environmentalists are not as excited about the
generators potential. Chris Johnson is a spokesman for the Illinois Public Interest Research Group,
a public policy advocacy group that focuses on the environment. He says fuel cell power
generators are a step in the right direction. But he says since this generator uses natural gas instead
of pure hydrogen to create electricity, it’s not a long-term answer to the nation’s energy problems:


“In other words, we’re sort of losing energy. It’s becoming less efficient, and in that sense we are
also having more CO-2 emissions in the long run. Also with natural gas emitting heat and CO-2,
Carbon dioxide is a huge cause of global warming.”


Johnson does concede that fuel cells are better for the environment than coal- and oil-based power
plants. But he also says fuel cells will not reach their full potential until they run off more basic
forms of hydrogen. The generators are also meeting some skepticism from the power generation
industry.


“I think fuel cells are everyone’s Holy Grail of engine power.”


Mike Osenga is the publisher of Diesel Progress Magazine, an engine and power generation trade
publication. He says such generators show promise, but also have a lot to prove:


“There hasn’t been long term testing, a lot of the engineering still needs to be done, and it’s still a
technology that has to prove itself, but it certainly seems to have some potential compared to some
of the other technologies people are considering.”


Osenga says the other issue is money. Using such a generator costs at least three cents more per
kilowatt-hour than taking the power from the local utility company. But Caterpillar and Fuel Cell
Energy are hoping customers will think the cost is worth it to have a more reliable power source.
Rich Thompson is a group president at Caterpillar. He says in light of the major blackout this past
summer, the industry is moving toward what he calls distributed power generation.


“A term you are going to hear more and more frequently, because distributed generation is the key
answer and the rapid answer to strengthening our national grid. And that is going to happen
following the northeast blackout.”


Thompson also says Caterpillar is lobbying Congress to give the company tax subsidies that other
cleaner power providers receive. That could make the fuel cell generators almost even in cost with
traditional utility power.

Nuns Drive Toward Greener Lifestyle

For many people, the meaning of spirituality comes from revering a higher
power. But in northern Ohio, there’s a group of nuns working to make
spirituality a little more grounded. The Great Lakes Radio Consortium’s
Renita Jablonski introduces us to the woman who helped start it all:


Sister Mary Shrader drives to work every day in a Honda Civic. It runs
on natural gas. When she pulls into the campus of the Sisters of St.
Joseph, she parks right in front of two compressed natural gas fueling pumps. With a flip of her gray hair, she gets ready to refuel.


“This is very easy and it’s very convenient to come in to work, plug your car in, and when you come out, it’s all filled. (sound of plug being put into car) In a few seconds, the compressor will kick in.”

(sound of compressor)


The Sisters of St. Joseph have 12 CNG cars so far. They’re members of the Northeast Ohio Clean Fuels Coalition. The addition of alternative fuel vehicles to their fleet was one of Shrader’s first projects when she was elected to
the congregation’s leadership council five years ago. That’s when the sisters
first adopted a resolution to pursue unity with the earth.


Shrader entered the convent when she was 17. It was 1960. She says back then, the congregation’s teachings often considered the natural world separate from the spiritual world.


“But they are, they’re totally integrated and the respect that you get from
your spirituality flows into the earth entities and Earth gives us the awe and the inspiration.”


Before coming to the Cleveland diocese, Shrader worked in Alaska in the Diocese
of Fairbanks. It’s when she first started to realize that environmental work was
her true calling.


“I’ve always wanted to live in the country, I’ve always wanted to be with animals and well, I got there and it was not exactly as I had envisioned it because much of the
economy of the state is run on oil business and on military and on tourism.”


Before she knew it, Shrader found herself joining an environmental group,
doing work opposing oil drilling in the Arctic National Wildlife Refuge. As an
English teacher, she made it a point to teach Thoreau’s Walden to get her students to think about their relationship with nature. And now, she’s leading her sisters in Cleveland on a very green path. Shrader’s latest project is a wind power study.


Last week, Green Energy Ohio installed a 130-foot wind energy-monitoring tower on the congregation grounds.


“We have done an energy audit so that we can lower the amount of energy that we use, and use it more efficiently.


They’ve also met with a consultant to evaluate every product used on site to make sure everything’s earth-friendly. Shrader is trying to integrate this environmental ethic into the sisters’ daily lives.


“I would hope we would be able to complete the educational program that we’ve
begun for residents and staff here so that they understand that this is a part of everything we do here. So no matter what area they work in, the kitchen,
maintenance, secretarial staff, health care, the priority of earth-friendly
should be a part of the decision making, the choices, and the actions that are here.”


Shrader is working with other community and religious organizations to promote
environmental awareness. The sisters are also busy reshaping their campus to become a nature trail system with special wildlife areas.

They’ve already applied to be an official bird sanctuary.

Nation Failing in Radon Remediation?

A coalition of scientists is reporting that efforts to reduce radon levels in homes throughout the
U.S. are largely failing. The Great Lakes Radio Consortium’s Celeste Headlee has more:


Radon is a natural gas that emits low levels of radiation. Research has proven it can cause lung
cancer. Officials estimate 15 thousand lung cancer deaths can be traced back to radon each year
in the U.S. Congress passed the Indoor Radon Abatement Act in 1988, setting a national goal to
reduce radon in American homes to safe levels.


Peter Hendrick is the Executive Director of the American Association of Radon Scientists and
Technologists. He says the country’s radon program is ineffective, with dangerous levels of the
gas still present in ten million homes in the U.S.


“I believe that the reason behind that is because one particular agency, Housing and Urban
Development, has really not lived up to its responsibilities under the National Environmental
Protection Act to comply with EPA standards on radon.”


Hendrick is calling for the government to enforce existing laws and even create tax incentives for
compliance. Federal officials have not yet commented on Hendrick’s complaints.

An environmental group is calling on Great Lakes states to ban drilling for
oil and gas under Lake Erie. The Great Lakes Radio Consortium’s Natalie
Walston reports:


At least four drilling companies have tried to gain access to oil and gas
deposits under Lake Erie since 1998. That’s according to a study by the Ohio
Public Interest Research Group. The group found a significant amount of
cooperation between the Council of Great Lakes Governors in considering
allowing companies access to the lake. Bryan Clark wrote the report for the interest
group. He says there are a number of problems associated with drilling for
oil and gas.


“Drilling operations routinely utilize dangerous toxic chemicals. Many of
these chemicals, such as those found in drilling mud, can cause problems as
diverse as wildlife cancers, developmental disorders, and shortened life
spans.”


Ohio governor Bob Taft has stated he will sign an executive order banning
drilling under Ohio’s part of Lake Erie. The state of Michigan recently voted to ban
new drilling. Clark says New York, Wisconsin, Illinois, and Indiana need to
consider a drilling ban as well.

Canadian environmental groups say the American demand for fossil fuels is harming
Canada’s environment. The Great Lakes Radio Consortium’s Karen Kelly reports:


Environmentalists say Canada’s oil industry is booming. Natural gas production
increased by 70% over the past decade. And oil production went up by 50%.
Canada is now the single largest supplier of fossil fuels to the United States. John
Bennett of the Sierra Club of Canada says that increase in fuel production and
consumption is harmful for both humans and wildlife.


“What we get is air pollution, 16 thousand premature deaths every year. We also have
huge loss of habitat and biodiversity.”


Environmentalists are especially concerned about a proposed pipeline through the
Canadian arctic. They’re also fighting to maintain a moratorium on drilling off the coast
of British Columbia.

Drilling Ban for Great Lakes

Congress has passed a measure banning drilling for oil or natural gas in the Great Lakes. The Great Lakes Radio Consortium’s Lester Graham has the details:

Transcript

Congress has passed a measure banning drilling for oil or natural gas in the Great Lakes. The Great Lakes Radio Consortium’s Lester Graham reports.


The legislation includes a two-year moratorium on new oil and gas drilling in or under the Great Lakes. US Senators Debbie Stabenow, a Democrat from Michigan and Peter Fitzgerald, a Republican from Illinois came up with the plan. They say the measure was needed in order to protect the waters of the Great Lakes from environmental damage. In Michigan, Governor John Engler denounced the measure. Engler is a long-standing supporter of drilling under the lakes for new energy sources. Susan Shafer is the governor’s press secretary.


“We’re concerned about the federal government coming in and telling us that Michigan and other Great Lakes states: ‘This is what you will do; you don’t have a choice on this.’ And, in the past there have been no federal statutes that have governed control over oil or natural gas in the bottomlands of the Great Lakes. And, so, that’s always been governed by state statute.”


Michigan was preparing to issue new drilling permits. Because of term limits, Engler leaves office at the end of next year. The candidates running for governor in Michigan all oppose new drilling permits. For the Great Lakes Radio Consortium, this is Lester Graham.

Point: Safe Oil Drilling in Lakes Is Possible

A Michigan Department of Natural Resources proposal to lease Great Lakes bottomlands for oil and gas development has prompted a lot of discussion regarding the risks and benefits of drilling near the Great Lakes. As commentator Michael Barratt reveals, those resources can be developed now in an environmentally safe manner.

People around the Great Lakes have seen quantum jumps in the price of energy within the last few months. Gasoline prices in Michigan for example are approaching $2.00/ gallon, natural gas prices have increased 40-60%, and propane prices have increased markedly.


Since Michigan only produces 4% of its crude oil demand and 30% of its natural gas demand, we need to find ways to both conserve and maintain our energy supply.


The Michigan Department of Natural Resources has proposed to lease land under the Great Lakes for the purpose of drilling wells from onshore locations. The proposed procedures require new wells to be located at least 1,500′ from the shoreline. They also require that sites be screened, and no drilling is to be permitted in dune areas, floodplains, or environmentally sensitive areas.


Additional wells drilled under Great Lakes waters may encounter significant reserves to help Michigan have a secure energy supply. Using a safe and proven technology known as directional drilling, it is possible to reach and produce these reserves with little to no effect on the surrounding areas. There have been 13 wells drilled under Great Lakes waters from onshore locations since 1979. Seven of those wells, which are still producing, have produced 439,000 barrels of oil and more than 17 billion cubic feet of gas. There have been no spills, accidents, or incidents associated with the wells since they have been drilled.


New wells drilled under Great Lakes waters, if drilling is allowed , could produce an additional 90 billion cubic feet of gas, and 2 million barrels of oil; enough to heat more than 1 million homes and fuel 157,500 cars for a year. We now have a window of opportunity to use existing infrastructure associated with the currently producing wells to develop some of the additional reserves under the Great Lakes. Drilling pads, roads, pipelines, and production facilities are in place that can be used to drill new wells under the Great Lakes.


Besides energy security, the people of Michigan benefit from royalties paid to the State of Michigan. That money is put into the Michigan Natural Resources Trust Fund to develop and extend parks, and to purchase wetlands and other environmentally sensitive areas. The seven wells currently producing have contributed more than $16,000,000 to the Fund. Additional wells drilled under the Great Lakes could contribute another $85,000,000-$100,000,000


Let’s develop the State’s Bottomland resources now in a safe and environmentally friendly way to ensure that Great Lakes waters and shorelines can be enjoyed by future generations and also to make sure we have the energy supplies here to maintain our quality of life.

Counterpoint: Drilling Not Worth Risk

As the debate on a national energy policy intensifies, the hunt for more places to drill and dig for new energy is escalating. States are now turning their attention to prospecting in one place that hits close to home: the Great Lakes.

As the debate on a national energy policy intensifies, the hunt for more places to drill and dig for new energy is escalating. States are now focusing their attention on prospecting for one place that hits close to home: the Great Lakes. As commentator Cameron Davis of the Lake Michigan Federation explains, drilling under the continent’s largest body of fresh surface water is not something to be taken lightly.


No matter which estimate you believe – that there’s only enough oil and gas to power a Great Lakes state for 2 minutes or 8 weeks – opening the Great Lakes to new oil and gas drilling is simply not worth the risk. Hydrogen sulfide, known to exist in lakebed oil and gas reserves, can escape during drilling causing far-reaching human health problems. Wellhead and pipeline leaks can contaminate groundwater and surface water in streams, often without adequate cleanups by the state agency responsible for drilling oversight. And, drilling can damage some of the most fragile fish and wildlife habitat known, habitat that exists along Great Lakes coasts.


The argument that drilling means more royalties to states doesn’t even hold up. One state Auditor General recently found that oversight of leasing and royalty payments from drilling operations continues to be lax. What does this mean? It means that taxpayers aren’t getting the financial benefits from drilling that they’re supposed to get.


Last, it’s not unusual for the same state agency to serve as subjective promoter of drilling while at the same time supposing to be the objective regulator. States such as Michigan, which is leading the charge for new drilling, can’t have it both ways and maintain their credibility. If they try to have it both ways, it’s inevitable that Congress will step in – as it did this summer with its own legislation.


President Bush, legislative leaders from both sides of the aisle, and a majority of citizens have all said that Great Lakes oil and gas drilling isn’t worth the risk. So why does a bad idea keep moving forward?

Wind Power Cheaper Than Gas and Coal?

A new study suggests wind power is cheaper to produce than coal or natural gas. The Great Lakes Radio Consortium’s Jonathan Ahl reports:

Transcript

A new study suggests wind power is cheaper to produce than coal or natural gas. The Great Lakes Radio Consortium’s Jonathan Ahl reports.


The report from Stanford University shows creating electricity using wind power costs about three and a half cents per kilowatt-hour. That compares to coal and natural gas costs of almost four cents per kilowatt-hour. Mark Jacobson is an engineering professor at Stanford, and the author of the study. He says the government needs to pursue using more wind power over coal and natural gas.


“ …and also, wind energy is more efficient than solar, or other renewable energy sources. So all of the renewable energy sources, you would want to exploit wind first.”


Jacobson says wind power is even a better deal when the environmental costs of pollutants from coal and gas plants are taken into consideration. But there is a downside. To convert two thirds of the nation’s coal generated electricity to wind power would take an up front investment of more then 330-billion dollars.
