Fuel Cells and the Hydrogen Economy
Euro Japan is developing expertise in this area and is keen
to talk with companies that have a direct or indirect interest.
Chris Taylor, who has been following the
hydrogen sector for almost 10 years, has written the following overview
of the sector.

Hydrogen could meet the Worlds total current primary energy
requirement. The capital investment required to achieve the complete
switch over would be less than $9 trillion. This could be financed
within a decade by the annual $1 trillion switched from expenditure
on oil.
Such an investment is cheaper than the $10 trillion needed to only
incrementally expand and replace parts of the Worlds power
sector over the next 30 years (International Energy Agency).
The economic argument for doing so is overwhelming. The figures
mentioned above do not take into account either the further advances
in fuel cells materials technology or the massive environmental
benefits of the switch. Both these would reinforce the economic
argument.
The economic argument for hydrogen. 
2010 is a realistic date for the mass production of fuel cell related
products to be underway. On the basis of the table below this fits
in with companies current field testing of products and the
normal pattern of manufactured product research, design,
build and mass production.
Fuel cell assembly is more akin to light manufacturing/assembly
so that a plant would take 2 years to construct rather than the
3 to 4 years required for a traditional engine or component facility.
Slippage in the timetable is most likely to occur
at this point or at the field test stage, when the product may have
to be redesigned/retested because of component failures.

The impending hydrogen economy, powered by fuel cells, will have
far-reaching implications for all aspects of life as we know it.
At the industry level, hydrogen will not only force a restructuring
of the oil, utility and transportation sectors but will also affect
others such as consumer electronics, IT and telecommunication.
Geopolitically, the wide-spread but localised production of hydrogen
will break the current global dependence upon oil and the Middle
Easts pivotal role.
The environment will benefit significantly, not only from the lower
emission of green-house gases but also from the use of renewable
energy sources to produce the hydrogen. The resultant hydrogen economy
will see individual consumers become self sufficient and independent
of both centralised electricity generation and national power distribution
networks.
The use of hydrogen to generate electricity is not new, it has
been known for over 120 years. However, recent developments in materials
technology have dramatically reduced the cost of fuel cells whilst
sharply improving their power density. This in turn has triggered
a dramatic expansion in research and development funding by both
the government and industry that will help accelerate the commercial
adoption of the hydrogen fuel cell.
Already
the worlds current production of hydrogen is sufficient to
power 14% of the global vehicle fleet. Several multinational firms
have significant product field tests underway including fleets of
hydrogen powered vehicles. Indeed, Daimler-Chrysler will have 30
such buses and 60 cars in operation by the end of 2004.

$1 Trillion & 5.1 Million Barrels Of
Oil
Based upon the Worlds primary energy consumption during 2002,
global energy requirements would halve. 5,108 million tonnes of
oil equivalent would be saved due to fuel cells greater efficiency.
$1 trillion annually that would normally have been spent upon
other primary energy sources. At a price of $40 per barrel the amount
saved would surpass $1,500 billion per annum, funding the entire
switchover to hydrogen within 6 years.
Given the 30 year forecast 60% increase in the Worlds total
primary energy requirement the entire cost, not just the incremental
expense, of the switch to hydrogen would be $14,500 billion. By
then the annual saving at $28 per barrel would increase
to a minimum of $1,600 billion each year. The corresponding figure
for oil at $40 a barrel would be $1,900 billion.
Worldwide : $9 Trillion Over The Next 25
Years
Assuming the worlds economy is completely converted to Hydrogen
use based on 2002 energy consumption figures, including nuclear
and hydro power, and that roughly 3 months worth of primary energy
is stored then the total cost would be almost US$ 20,000 billion.
The US would account for around 1/3 the required capital investment.
Once the figures are adjusted for fuel cells more efficient
use of the energy liberated (2 to 3 times better than hydrocarbon
based rival technologies) then the implied total cost of the hydrogen
infrastructure drops to just over $9,000 billion. The US share would
be $3,000 billion, or $125 billion a year if spread over the next
25 years.
By way of comparison US GDP is currently worth around US $12,000
billion annually whilst the Afghanistan War and the second Gulf
War have each already cost US $200 billion (and still rising). In
addition around $50bn to $100bn has to be spent on mending
the US power distribution grid to prevent a recurrence of the recent
blackouts in the North East and in California.

$1 Trillion Annual Sales And 100% + 25 Year Growth
Rates
The initial market opportunities will be in the hydrogen infrastructure
markets, worth $9 trillion in total, and this would equate to a
25 year growth rate of around 140%. The renewal of the infrastructure
based on a 25 year life cycle, would be worth an eventual $375 billion.
a year by 2030. By the same date, the total fuel cell based product
markets plus the retail value of all the electricity generated globally
would be worth around U$ 161 billion annually, amounting to a 25
year growth rate of almost 110%. (If the final value of the products
that incorporate fuel cells is included then the annual sales figure
becomes almost US$ 1 trillion.) Again the US would comprise roughly
1/3rd of the global total, or roughly $55 billion and $300 billion
of fuel cells and fuel cell based products sold respectively, and
another $125 billion on infrastructure replacement.
Fuel Cells Twice As Efficient (Up To 5x At $2
Per Gallon)
As an energy source hydrogen is initially more expensive than
petrol. But, the hydrogen fuel cell greater efficiency is key to
that combination being far more economic than the petrol driven
internal combustion engine. This means that a fuel cell will only
use about half the amount of energy to achieve the same task. At
$1.25 per gallon the relative frugality of the fuel cell lifts its
overall energy efficiency to two to three times that of the petrol
powered alternative. At the $2 per gallon its relative overall efficiency
is nearer five times.

Efficiency Doubles Every 2 Years Like Semicondutors
Proton Exchange Membrane, or PEM, based fuel cells that primarily
use platinum are set to follow the same path of technological improvement
that semiconductors have done. Their efficiency will roughly double
every 2 to 3 years or the size of the installation will halve in
volume and weight.
Current PEM systems are already more energy dense than a similar
power output internal combustion engine installation.
The key is the parallel advances being made in the materials that
form the membranes and the catalysts used. These advances will depend
upon knowledge of interactions at the molecular level, so will be
one of the first widespread applications of nanotechnology.

Close To Petrols Local Hydrogen Production
Viable
At $1.25 a gallon the cost per Giga Joule (GJ) of energy available
from petrol is about the same as that of centrally produced Hydrogen.
At $2 per gallon Hydrogen is 50% cheaper. When the cost of centrally
produced hydrogen and its delivery are compared, there is relatively
little difference, both coming in at between $15 to $25 per GJ but
when adjusted for the fuel cells efficiency it drops to between
$8 and $13.
