Hydrogen: Empowering the People
by Jeremy Rifkin

While the fossil-fuel era enters its sunset years, a new energy
regime is being born that has the potential to remake
civilization
along radically new lines--hydrogen. Hydrogen is the most basic
and
ubiquitous element in the universe. It never runs out and
produces no
harmful CO2 emissions when burned; the only byproducts are heat
and
pure water. That is why it's been called "the forever
fuel."
Hydrogen has the potential to end the world's reliance on oil.
Switching to hydrogen and creating a decentralized power grid
would
also be the best assurance against terrorist attacks aimed at
disrupting the national power grid and energy infrastructure.
Moreover, hydrogen power will dramatically reduce carbon dioxide
emissions and mitigate the effects of global warming. In the long
run, the hydrogen-powered economy will fundamentally change the
very
nature of our market, political and social institutions, just as
coal
and steam power did at the beginning of the Industrial
Revolution.
Hydrogen must be extracted from natural sources. Today, nearly
half
the hydrogen produced in the world is derived from natural gas
via a
steam-reforming process. The natural gas reacts with steam in a
catalytic converter. The process strips away the hydrogen atoms,
leaving carbon dioxide as the byproduct.
There is, however, another way to produce hydrogen without using
fossil fuels in the process. Renewable sources of energy--wind,
photovoltaic, hydro, geothermal and biomass--can be harnessed to
produce electricity. The electricity, in turn, can be used, in a
process called electrolysis, to split water into hydrogen and
oxygen.
The hydrogen can then be stored and used, when needed, in a fuel
cell
to generate electricity for power, heat and light.
Why generate electricity twice, first to produce electricity for
the
process of electrolysis and then to produce power, heat and light
by
way of a fuel cell? The reason is that electricity doesn't store.
So,
if the sun isn't shining or the wind isn't blowing or the water
isn't
flowing, electricity can't be generated and economic activity
grinds
to a halt. Hydrogen provides a way to store renewable sources of
energy and insure an ongoing and continuous supply of power.
Hydrogen-powered fuel cells are just now being introduced into
the
market for home, office and industrial use. The major auto makers
have spent more than $2 billion developing hydrogen-powered cars,
buses and trucks, and the first mass-produced vehicles are
expected
to be on the road in just a few years.
In a hydrogen economy the centralized, top-down flow of energy,
controlled by global oil companies and utilities, would become
obsolete. Instead, millions of end users would connect their fuel
cells into local, regional and national hydrogen energy webs
(HEWs),
using the same design principles and smart technologies that made
the
World Wide Web possible. Automobiles with hydrogen cells would be
power stations on wheels, each with a generating capacity of 20
kilowatts. Since the average car is parked most of the time, it
can
be plugged in, during nonuse hours, to the home, office or the
main
interactive electricity network. Thus, car owners could sell
electricity back to the grid. If just 25 percent of all US cars
supplied energy to the grid, all the power plants in the country
could be eliminated.
Once the HEW is set up, millions of local operators, generating
electricity from fuel cells onsite, could produce more power more
cheaply than can today's giant power plants. When the end users
also
become the producers of their energy, the only role remaining for
existing electrical utilities is to become "virtual power
plants"
that manufacture and market fuel cells, bundle energy services
and
coordinate the flow of energy over the existing power grids.
To realize the promise of decentralized generation of energy,
however, the energy grid will have to be redesigned. The problem
with
the existing power grid is that it was designed to insure a
one-way
flow of energy from a central source to all the end users. Before
the
HEW can be fully actualized, changes in the existing power grid
will
have to be made to facilitate both easy access to the web and a
smooth flow of energy services over the web. Connecting
thousands,
and then millions, of fuel cells to main grids will require
sophisticated dispatch and control mechanisms to route energy
traffic
during peak and nonpeak periods. A new technology developed by
the
Electric Power Research Institute called FACTS (flexible
alternative
current transmission system) gives transmission companies the
capacity to "deliver measured quantities of power to
specified areas
of the grid."
Whether hydrogen becomes the people's energy depends, to a large
extent, on how it is harnessed in the early stages of
development.
The global energy and utility companies will make every effort to
control access to this new, decentralized energy network just as
software, telecommunications and content companies like Microsoft
and
AOL Time Warner have attempted to control access to the World
Wide
Web. It is critical that public institutions and nonprofit
organizations--local governments, cooperatives, community
development
corporations, credit unions and the like--become involved early
on in
establishing distributed-generation associations (DGAs) in every
country. Again, the analogy to the World Wide Web is apt. In the
new
hydrogen energy era, millions of end users will generate their
own
"content" in the form of hydrogen and electricity. By
organizing
collectively to control the energy they produce--just as workers
in
the twentieth century organized into unions to control their
labor
power--end users can better dictate the terms with commercial
suppliers of fuel cells for lease, purchase or other use
arrangements
and with virtual utility companies, which will manage the
decentralized "smart" energy grids. Creating the
appropriate
partnership between commercial and noncommercial interests will
be
critical to establishing the legitimacy, effectiveness and
long-term
viability of the new energy regime.
I have been describing, thus far, the implementation of hydrogen
power mainly in industrialized countries, but it could have an
even
greater impact on emerging nations. The per capita use of energy
throughout the developing world is a mere one-fifteenth of the
consumption enjoyed in the United States. The global average per
capita energy use for all countries is only one-fifth the level
of
this country. Lack of access to energy, especially electricity,
is a
key factor in perpetuating poverty around the world. Conversely,
access to energy means more economic opportunity. In South
Africa,
for example, for every 100 households electrified, ten to twenty
new
businesses are created. Making the shift to a hydrogen energy
regime--using renewable resources and technologies to produce the
hydrogen--and creating distributed generation energy webs that
can
connect communities all over the world could lift billions of
people
out of poverty. As the price of fuel cells and accompanying
appliances continues to plummet with innovations and economies of
scale, they will become far more broadly available, as was the
case
with transistor radios, computers and cellular phones. The goal
ought
to be to provide stationary fuel cells for every neighborhood and
village in the developing world.
Renewable energy technologies--wind, photovoltaic, hydro,
biomass,
etc.--can be installed in villages, enabling them to produce
their
own electricity and then use it to separate hydrogen from water
and
store it for subsequent use in fuel cells. In rural areas, where
commercial power lines have not yet been extended because they
are
too expensive, stand-alone fuel cells can provide energy quickly
and cheaply.
After enough fuel cells have been leased or purchased, and
installed,
mini energy grids can connect urban neighborhoods as well as
rural
villages into expanding energy networks. The HEW can be built
organically and spread as the distributed generation becomes more
widely used. The larger hydrogen fuel cells have the additional
advantage of producing pure drinking water as a byproduct, an
important consideration in village communities around the world
where
access to clean water is often a critical concern.
Were all individuals and communities in the world to become the
producers of their own energy, the result would be a dramatic
shift
in the configuration of power: no longer from the top down but
from
the bottom up. Local peoples would be less subject to the will of
far-off centers of power. Communities would be able to produce
many
of their own goods and services and consume the fruits of their
own
labor locally. But, because they would also be connected via the
worldwide communications and energy webs, they would be able to
share
their unique commercial skills, products and services with other
communities around the planet. This kind of economic
self-sufficiency
becomes the starting point for global commercial interdependence,
and
is a far different economic reality from that of colonial regimes
of
the past, in which local peoples were made subservient to and
dependent on powerful forces from the outside. By redistributing
power broadly to everyone, it is possible to establish the
conditions
for a truly equitable sharing of the earth's bounty. This is the
essence of reglobalization from the bottom up.
Two great forces have dominated human affairs over the course of
the
past two centuries. The American Revolution unleashed a new human
aspiration to universalize the radical notion of political
democracy.
That force continues to gain momentum and will likely spread to
the
Middle East, China and every corner of the earth before the
current
century is half over.
A second force was unleashed on the eve of the American
Revolution
when James Watt patented his steam engine, inaugurating the
beginning
of the fossil-fuel era and an industrial way of life that
fundamentally changed the way we work.
The problem is that these two powerful forces have been at odds
with
each other from the very beginning, making for a deep
contradiction
in the way we live our lives. While in the political arena we
covet
greater participation and equal representation, our economic life
has
been characterized by ever greater concentration of power in ever
fewer institutional hands. In large part that is because of the
very
nature of the fossil-fuel energy regime that we rely on to
maintain
an industrialized society. Unevenly distributed, difficult to
extract, costly to transport, complicated to refine and
multifaceted
in the forms in which they are used, fossil fuels, from the very
beginning, required a highly centralized command-and-control
structure to finance exploration and production, and coordinate
the
flow of energy to end users. The highly centralized fossil-fuel
infrastructure inevitably gave rise to commercial enterprises
organized along similar lines. Recall that small cottage
industries
gave way to large-scale factory production in the late nineteenth
and
early twentieth centuries to take advantage of the
capital-intensive
costs and economies of scale that went hand in hand with steam
power,
and later oil and electrification. In the discussion of the
emergence
of industrial capitalism, little attention has been paid to the
fact
that the energy regime that emerged determined, to a great
extent,
the nature of the commercial forms that took shape.
Now, on the cusp of the hydrogen era, we have at least the
"possibility" of making energy available in every
community of the
world--hydrogen exists everywhere on earth--empowering the whole
of
the human race. By creating an energy regime that is
decentralized
and potentially universally accessible to everyone, we establish
the
technological framework for creating a more participatory and
sustainable economic life--one that is compatible with the
principle
of democratic participation in our political life. Making the
commercial and political arenas seamless, however, will require a
human struggle of truly epic proportions in the coming decades.
What
is in doubt is not the technological know-how to make it happen
but,
rather, the collective human will, determination and resolve to
transform the great hope of hydrogen into a democratic reality.
