Fuel cells offer consumers and cooperatives the promise of on-site power generation
With an innovative spirit,
Indiana embraced electric cooperatives more than 65 years ago.
Consumer-owned co-ops set the poles and strung the lines along the
backroads and fields and into the hills and hollows to bring rural
Hoosiers the brilliance of light and the convenience of electricity.
Before electric co-ops, electricity was a rare
commodity across rural America. Small generators, fueled by kerosene or
gasoline, were the only sources of power for the majority of the
nation's farmers and rural residents whose pleas for affordable
central-station electricity were ignored by the existing electric
companies of the day.
Today, electric co-ops continue that
innovative pioneering spirit: testing the latest technology to bring
electricity to consumers' homes and businesses.
Ironically, some of the latest technology —
fuel cells — echoes the more distant past. Fuel cells promise on-site
power generation that doesn't use the poles and power lines that made
rural America prosper. In the coming years, rapidly evolving fuel cell
technology is expected to revolutionize the electric utility industry.
In fact, fuel cells are expected to do to poles and power lines some
day what poles and power lines did to windmills and those cumbersome
kerosene "light and power plants" at the heyday of rural
electrification.
The ‘descent’ of electricity
Recognizing the technology's potential for
powering homes and businesses, the nation's electric co-ops have
established joint ventures with fuel cell manufacturers to advance the
use of fuel cells.
At the 2001 Farm Progress Show near Lafayette
last September, Indiana's electric co-ops had a small fuel cell as part
of its exhibition. At 250 watts, the display unit generated more
conversation than electricity. Still, Ken Ritchey, general manager at
the host electric utility, Tipmont REMC, said it was received well by
visitors at the tent who asked a lot of questions.
Tipmont REMC is one of a handful of co-ops
around Indiana to show initial interest in fuel cell technology. But,
Ritchey said, practical application is still down the road aways.
How far, he said, is anybody's guess. He sees
spot application of fuel cells coming first. Within the next few years,
a new home or business built in a remote location without electric
service could be equipped with a fuel cell instead of having the
cooperative extend service via poles and lines.
As the technology progresses over the next
several decades, fuel cells will be used for stand-by power and then
for specific applications for consumers needing a higher level of
service and control than regular consumers. And eventually …?
"I think eventually," Ritchey said, "it'll make the wires business obsolete."
Several electric co-ops around the nation
tested an early model of a fuel cell just over a year ago and are now
awaiting the arrival of a beta unit, or a second generation model, to
test.
While fuel cells were first conceptualized in
the 1800s, the technology had only been applied in the exploration of
space. Until now. Researchers today are experimenting with fuel cells to
power everything from a wristwatch to vehicles to an entire home or business.
While there are a number of fuel cell
technologies in use or under development, the most practical for homes
and small businesses is the Proton Exchange Membrane system.
A PEM fuel cell silently produces electricity
through an electrochemical reaction in which hydrogen and oxygen are
combined to generate electricity. The hydrogen used in the process is
derived from fuels such as natural gas or propane; the oxygen is drawn
from the air.
About the size of a refrigerator, a PEM fuel
cell could not only provide the electrical needs of a home, but its
principal byproducts, heat and hot water, could also supply the hot
water and some space heat.
You won't find a fuel cell at your local
hardware store quite yet, however. H Power Corporation, a New
Jersey-based fuel cell manufacturer, for example, doesn't expect to
have commercial units available until the end of this year.
Those units are expected to produce up to five
kilowatts on a continuous basis, enough to power a typical home. A
smaller fuel cell powered by bottled hydrogen is expected to be
available commercially sooner.
In 1998, H Power provided the first traffic
signs powered by fuel cells to the New Jersey Department of
Transportation. H Power fuel cells are already being used commercially
in buses and radios. Now, H Power is partnering with electric
cooperatives to fine-tune its fuel cells.
The partnership is possible through Energy
Co-Opportunity, or ECO for short, an energy services cooperative
created by the nation's electric co-ops to stay on the forefront of
this type of technology. ECO has partnered with H Power to produce a
fuel cell designed specifically for electric co-op consumers.
Another fuel cell test is being conducted by
nine participants, mostly electric cooperatives, through the
Cooperative Research Network. CRN is a division of the National Rural
Electric Cooperative Association. The project is being supported by the
Electric Power Research Institute, a center for energy and
environmental research in Palo Alto, Calif.; the U.S. Department of
Energy; and the U.S. Army.
Those models are powered by natural gas, but future units could utilize fuels such as propane or even ethanol.
"We're in the typical stage for advanced
high-technology equipment," said Ed Torrero, senior program manager for
CRN. "Once they are put in the field, there are still a lot of changes
and improvements that need to be made."
Homeowners need to flip a switch and walk away
from a fuel cell, confident that they have a reliable form of
electricity, said Bob Gibson, director of marketing communications with
ECO. "It's got to be at that level. It's not there yet. Everybody knows
what they have to do, but they just have to keep tinkering."
Helping with that tinkering process,
Consolidated Electric Cooperative, which serves more than 13,600 homes
and businesses in eight counties of northcentral Ohio, was one of eight
co-ops to test the first generation, or alpha, fuel cells, which were
powered with natural gas.
Consolidated Electric, in a partnership with
Buckeye Power, Ohio's power generation and transmission co-op, first
put its fuel cell through a series of daily tests, powering a "ghost"
load. Eventually, the fuel cell was used to power an office heating
system, which used from 5,000 to 6,000 watts to operate.
Tests like these give H Power the knowledge it
needs to advance the development of fuel cells, Gibson said. During
field tests, manufacturers are finding the fuel processing area to hold
the most technical glitches, said Dan Rastler, with EPRI.
The technical glitches aside, fuel cells are
also expensive. Gibson estimates a commercial unit would cost
approximately $50,000. Like most technology, the price is expected to
drop as more units are produced. Expense, however, will continue to be
an issue for several years.
"It's going to take several years for it to deliver power as cheap as buying power off the grid," he said.
A role to play
But electric cooperatives envision various
roles for fuel cells, from providing supplemental power to serving as
the primary power source in remote areas.
A highly efficient power supply, fuel cells
could — as Tipmont's Ritchey noted — revolutionize the way consumers
receive electricity.
Imagine 50 years from now: the rural roadsides
devoid of the poles and power lines that have been a part of the
landscape for the lifetime of almost everyone living today. Imagine
what it would be like to hear weather forecasts calling for ice and
high winds without worrying if that old cedar tree out back is going to
take out your electric service.
"The technologies that are just breaking
through are the kinds of things we're going to see more and more of in
the future. They're going to be part of the mainstream in the way
energy is delivered and used across the country," Gibson said.
Fuel cells don't release emissions and are uniquely suited for providing power for remote locations, according to ECO.
In the near future, businesses could use fuel
cells for emergency use or to power essential equipment during an
outage. And electric co-ops could use fuel cells as an alternative to
building expensive line extensions or to manage peak loads in more
populated areas.
Fuel cells are "under intense technical
development and innovation," said Rastler. "We're bullish on the
long-term prospects of fuel cell technology."
"There is a great
potential for saving money for both co-ops and their consumers," Gibson
said. "In rural areas, in particular, because of the cost of building
and maintaining lines to serve relatively modest loads."
An extension from the main electrical grid
could cost from $10,000 to $15,000 per mile, Torrero said. "So it
doesn't take too many miles before an alternative such as a residential
fuel cell becomes economical."
Ritchey also noted that fuel cell technology
and its potential role in the future are already changing the way many
co-ops operate today. "I think it is probably causing every co-op to
think seriously, if they haven't already, about the propane business,"
he said. "If you want to be in the electric business and there are no
wires, then you better have access to fuel, or you won't be in the
electric business."
Electric cooperatives are poised to become
leaders in providing innovative power solutions. The national alliance
of Touchstone Energy co-ops has made innovation one its four
principles. The goal of consumer-owned co-ops is to get electricity to
consumers as inexpensively as possible. They do that with the current
technology today and will be doing it with the new technology tomorrow.
