The race to
put the first fuel cell cars onto the market has certainly heated
up. In January 2000, Ballard showed the automotive world its latest
fuel cell stack, the 900 series, which puts out 30% more power than
previous models of the same size. This seemed to confirm Ballard’s
lead in the competition to commercialize fuel cell cars. However,
only a month later General Motors announced that its own latest
fuel cell stack was now "15% smaller than the nearest competitor
and half the size of GM’s previous effort." And that summer
a GM fuel cell vehicle served as the pace car for the Olympic marathon
in Sydney, Australia.
Then, in September
2000 (with Chancellor Gerhard Schroeder in attendance), DaimlerChrysler
unveiled its most advanced Ballard-powered car, the Necar 5, which
runs on methanol. The corporation reaffirmed its commitment to bring
its first fuel cell cars to market in 2004. But a month earlier,
Honda had announced that it will begin to sell fuel cell cars as
early as 2003. Honda has been experimenting with Ballard fuel cells
for several years but also quietly developing its own technology.
The first Honda car demonstrated in California uses Ballard cells.
One Honda innovation is to use an ultracapacitor to store electricity
and use it for quick starts while the fuel cell is warming up.
Other companies
also seem to be serious contenders. Toyota is developing a "hybrid"
fuel cell car that will use a sizable storage battery to get started
and for an extra boost when accelerating or climbing hills. And
International Fuel Cells (IFC) of Connecticut, which made the alkaline
fuel cells for the space shuttle and marketed the first commercial
stationary (phosphoric acid) fuel cells, is now competing directly
with Ballard and the others. Hyundai is working already with IFC
to use that company’s proton exchange membrane fuel cells in its
first commercial car.
There was no
more visible demonstration of the fuel cell race than the gala opening
of the California Fuel Cell Partnership headquarters in Sacramento
in November 2000. Fourteen vehicles, including buses as well as
cars, were rolled out for the press and public. Of those, eleven
were powered by Ballard fuel cells. So, despite the competition,
Ballard still appears to be the world leader in automotive fuel
cells.
On the down
side, the California Air Resources Board, apparently bowing to pressure
from the auto industry, has eased off on the regulations that are
due to kick in as of 2003. Until recently, these would have required
that 10% of the vehicles sold be extremely low emission types, including
4% of them true zero emission vehicles (essentially requiring them
to be fuel cell or battery powered). Under the latest change, this
has been cut back to only 2%.
The reduced
numbers, along with the lack of movement toward establishing an
alternative fuel distribution system (e.g., for methanol) in California,
means that the first commercial fuel cell cars will almost certainly
be sold only for fleet use, where they can be refuelled at central
depots.
Fuelling
the Future
What fuel or
fuels the first generation of fuel cell vehicles will use remains
the most significant unanswered question that overshadows the hoped-for
rapid introduction of fuel cell cars. For buses, which can tank
up at central depots, this will clearly be compressed hydrogen.
For automobiles, though, there is not yet a consensus. DaimlerChrysler
still seems committed to methanol. But General Motors and Exxon
have promised that by around the end of 2002 they will demonstrate
a prototype reformer that would make hydrogen from a special grade
of gasoline.
Compressed hydrogen
for cars is also beginning to look somewhat more attractive. The
compressed hydrogen used in the Ballard and DaimlerChrysler buses
is stored in relatively heavy steel tanks at pressures up to around
3000 psi (pounds per square inch). This is a relatively bulky storage
system, and an acceptably sized auto tank using compressed hydrogen
would limit a fuel cell car’s range to something like only 100 miles.
But several companies have made great strides in developing new
types of tanks out of multi-layered composite materials, such as
carbon fibers and resins. These can store hydrogen at up to 5000
psi, thereby extending the car’s range by about 50%. The tanks also
weigh much less than steel, and some types can be molded to fit
well into oddly shaped spaces in car trunks. Where average driving
distances are somewhat shorter than in North America, notably in
Japan, highly compressed hydrogen could yet prove to be a practical
system. The same companies are even looking ahead at tanks that
could hold hydrogen at 10,000 psi, which would give more than adequate
range. However, there are major safety concerns, especially in case
of a crash, with so much hydrogen packed into a tank at such high
pressure.
Responding to
these concerns, other companies, notably Energy Conversion Devices
of Michigan, have moved rapidly to develop metal hydride systems
that store hydrogen in a solid and safe form. They claim that they
can already pack enough hydrogen into a conventional tank size to
achieve well over 300 mile range. But a hydride tank would be much
heavier than a tank of gasoline. And heat is required to release
the hydrogen for use in a fuel cell. However, many in the hydrogen
field see hydrides as the answer, and other companies and labs are
working on hydride storage as well. Still, none of them will be
commercialized in time for the first fuel cell cars.
Ballard itself
is giving some backing to a novel technology that derives hydrogen
from a solution of sodium borohydride in the presence of a ruthenium
catalyst. Sodium borohydride, a derivative of abundant borax, is
a safe and environmentally friendly material for a car to carry
around in its tank. Once the hydrogen has been removed, the byproduct
is, sodium borate, a water-soluble salt that is a common ingredient
in laundry detergent and can be recycled. In October 2000 Ballard
put up $2.4 million as an advance against prospective royalties
and agreed to develop the technology jointly with Millennium Cell
Inc. of New Jersey. In February 2001 the two companies announced
the first successful demonstration of the system at Ballard headquarters.
Ballard has also begun developing a so-called direct methanol fuel
cell, which would not need a reformer. This would eliminate one
major piece of equipment in a car and eliminate the problem of bringing
the reformer up to a relatively high temperature for cold starts.
Ballard engineers have already demonstrated a small go kart-like
vehicle using a prototype of this fuel cell stack.
On
the Buses
Ballard retains
a decisive lead in fuel cell buses. The Chicago and Vancouver prototype
bus fleets performed satisfactorily for two years and then were
taken out of service. But newer Ballard-built buses using the latest
fuel cell stacks have been put into service in California as part
of the California Fuel Cell Partnership, beginning in Oakland and
Palm Springs. Another 20 or so will be put on the roads of California
by the year 2003. Meanwhile, DaimlerChrysler committed itself to
building its first production series of Citario buses, powered by
Ballard cell stacks, for sale to European transit companies. In
March 2001 DaimlerChrysler announced that the first 30 of them have
been purchased at $1.13 million apiece. Ten different cities, from
Madrid to Reykjavik, will each be receiving three buses, with delivery
starting in late 2002 and continuing through 2003. As in North America,
these will run on compressed hydrogen. The Hamburg transit authority
will make hydrogen for its buses from electricity generated by wind
power, thereby creating a perfectly clean and carbon dioxide-free
power cycle.
Stationary
Power
It is not only
in transportation that fuel cell technology has moved rapidly towards
commercialization. Ballard Generation Systems has continued to sell
its 250 kilowatt stationary power systems, which run on natural
gas, with about a half-dozen such demonstration units already installed.
But serious competition has emerged for stationary power systems
of comparable size, which is large enough to power a small office
building. Ballard’s PEM system operates at a relatively low temperature,
below the boiling point of water. The excess heat that is produced
can be recaptured to a degree and used, for example, to heat water
for the building. Overall efficiency is around 40 to 42%. But with
higher temperature fuel cells, the excess heat can generate steam,
which can in turn be used to power a turbine and achieve considerably
higher efficiencies.
Two important
players with high temperature technologies are challenging Ballard’s
position. One is FuelCell Energy, of Connecticut, which has developed
a 300 kilowatt molten carbonate fuel cell that is claimed to have
an efficiency in the range of 50 to 55%. Siemens-Westinghouse has
developed a 200 kilowatt solid oxide fuel cell and combined it with
a small turbine. This "hybrid" system may achieve efficiencies
of 65% or higher. Because Ballard’s stationary fuel cell stack uses
essentially the same materials and simple sandwich-like construction
as its transportation fuel cells, economies of scale from the transportation
side should give Ballard an edge on the initial cost of its stationary
units. However, with the price of natural gas apparently on the
rise, fuel efficiency could prove to be a more decisive consideration
in the long run. These large stationary systems should be available
commercially by late 2002 or in 2003.
Also rapidly
approaching commercialization are small stationary home fuel cell
units, which Ballard is initially aiming at the Japanese market.
In early 2000 Ballard announced a joint collaboration effort with
Tokyo Gas and EBARA, which was already a part owner of Ballard Generation
Systems. Together, they began designing a one-kilowatt generator
that will operate on natural gas and provide a substantial portion
of the electricity needs (plus hot water) for individual Japanese
houses and apartments that also have connections to the electricity
grid. And they have now demonstrated a one-kilowatt prototype of
this system. EBARA showed its commitment to this joint venture by
injecting $19 million in new money into Ballard Generation Systems,
which boosted its ownership from 6% to 11.4%.
However, there
is now intense competition in North America for stationary home
fuel cells. Both H Power of New Jersey and Plug Power of New York
are developing home PEM units in the three to seven kilowatt range,
enough to supply sufficient electricity (plus hot water) for houses
that are not on the utility grid. And in Canada, Global Thermoelectric
is working on similar small stationary units that use a solid oxide
fuel cell stack. All of these (including Ballard’s) should be reaching
market in 2002 or 2003.
Leading
the Way
But the very
first Ballard-powered product to go on sale to the public is likely
to be a small, portable fuel cell generator for home use in case
of power failures, for camping trips and for light industrial use,
such as at building sites. This is being developed in a joint effort
between Ballard and the huge US company Coleman Powermate, which
is already a leading manufacturer of gasoline-powered generators.
Ballard and Coleman Powermate promise to have this generator on
sale as soon as late 2001. It is expected to run on propane. In
a separate development, Ballard entered a deal with huge Matsushita
Electric Works of Japan (parent company to Panasonic) to develop
a very small (250 watt) portable generator that will run on little
tanks of butane. The prototype has already been demonstrated, but
no date for commercial sale yet announced.
In short, Ballard
remains the apparent world leader in fuel cell technology. And it
is the only company that is competing in all the major application
areas: transportation, large stationary, home stationary, and small
portable fuel cells.
To manufacture
the fuel cell stacks needed for all these projects during the next
few years, Ballard has built a $40 million 9900 sq. metre (110,000
sq. ft.) manufacturing facility next to its corporate headquarters
in Burnaby, B.C. It went into production in December 2000. But looking
ahead to the huge expansion required to supply fuel cells for the
automobile market, Ballard also raised hundreds of millions of dollars
floating new shares in 2000. By the mid-2000, therefore, Ballard
was sitting on $569 million in cash, most of it earmarked for construction
of a much larger manufacturing facility. The likely location is
somewhere in the United States.
Given all the
promising news on the fuel cell front, Ballard’s share price soared
in 2000, briefly quadrupling to hit dizzying new highs and averaging
well over double its 1999 level. Ballard Power remained one of the
darling stocks on the NASDAQ and Toronto exchanges. But then came
the technology stock meltdown of latter part of 2000, which continued
into early 2001. This brought Ballard’s share price back down to
just a little above where it was in the later part of 1999. For
investors, it has been a wild roller coaster ride, and no doubt
many people have been hurt financially in the process. However,
for those who placed their bets on Ballard in the mid-1990s and
have held for the long term, it has still been an excellent investment.
And with the needed money in hand and earmarked for its large manufacturing
plant, Ballard Power appears to be in a stable, cash-rich position.
At the company
itself, Firoz Rasul has now moved up to chair the Board of Directors
while remaining CEO as well. And Lyle (Kip) Smith has assumed the
position of President as well as COO.
Meanwhile, the
founders of Ballard Power have not been content to rest on their
laurels. Geoffrey Ballard and Paul Howard have formed a new company,
called General Hydrogen, with Ballard as its Chair. Its aim is to
channel investment money into selected companies and technologies
(including, of course, fuel cells) that will be at the forefront
of the coming "hydrogen age." So the Ballard saga continues.
Stay tuned.
