GM Shows Experimental Hydrogen HUMMER H2H

It was only a matter of time until GM debuted a hydrogen powered HUMMER
concept, and that time has arrived. The General's HUMMER H2H shown here is
billed as a one-of-a-kind experimental hydrogen vehicle with no production
plans in the works. Still, it's good to see some advanced technology being
applied to the vehicle and, as always, we'd sure like to see a hybrid
powerplant make its way between the HUMMER's fenders...something that's not
so far-fetched. After all, hybrid powerplants have been developed for the
military version of the HUMMER and have been undergoing testing for some
time.

The Hydrogen HUMMER H2 SUT debuted with California Governor Arnold
Schwarzenegger behind the wheel at a BP hydrogen station opening at Los
Angeles International Airport. Powered by a supercharged 6.0-liter Vortec
V-8 modified to run on gaseous hydrogen, the HUMMER H2H is the result of a
team effort by GM engineers in the U.S., Canada, and Germany, along with GM
fuel cell partner Quantum Technologies.

Arnold Schwarzenegger Unveils First BP-Branded Retail-Designed Hydrogen Site
In US

AIADA Oct 22, 2004

LOS ANGELES -- Arnold Schwarzenegger, the Governor of California, today
officially dedicated the state's first retail-designed hydrogen
demonstration refueling station, at a BP-branded site at Los Angeles
International Airport. The station has been developed in partnership with
Praxair, South Coast Air Quality Management District and Los Angeles World
Airport and will provide hydrogen for five DaimlerChrysler fuel cell cars.

Speaking at the dedication ceremony, Ross Pillari, President, BP America,
said: "The opening of this hydrogen demonstration site is an important step
to meeting the future energy needs of California. It is also an important
milestone for us in BP and for the US. It, along with other development
projects, will bring the day when hydrogen can be made widely available to
customers a step closer.

Carol Battershell, BP's Director of Alternative Fuels added: "Today's
celebration reflects our belief in the potential hydrogen offers for wide-
scale emission-free transport. And while the day when that may be possible
is still sometime away, projects such as this demonstrate what we can do
today to provide the fuels of tomorrow."

BP, which markets its traditional fuels in California under the ARCO brand,
is also working in partnership with the US Department of Energy,
DaimlerChrysler and Ford to develop further hydrogen refueling stations in
several US states. Elsewhere in the world, the company is a participant in a
pan-European nine-city fuel cell bus project and has signed an agreement
with the Chinese Government to develop hydrogen demonstration fueling
facilities to support fuel cell buses in Beijing, in time for the 2008
Olympic Games.

The Los Angeles Airport project brings BP's worldwide involvement in
hydrogen sites to 12. Earlier this week, the company unveiled the first
hydrogen refueling facility to be built under the DOE's fuel cell and
infrastructure validation program, at the DTE Energy Hydrogen Technology
Park in Detroit.

Notes about BP and Hydrogen fuel:

Hydrogen is the world's cleanest transport fuel. When used in a fuel cell,
the only emission produced is water.

There are a range of pathways to producing, delivering and storing hydrogen.
It can be produced from natural gas either centrally at a refinery or on
site; or manufactured on site using electrolysis. It can be delivered,
stored and dispensed in gaseous form or as a liquid.

One of the biggest challenges is to produce hydrogen from water using
electricity provided from renewable sources, such as solar or wind power.
This would make hydrogen a wholly sustainable fuel.

BP is participating in hydrogen demonstration projects around the world. In
Europe, BP is the leading energy company participant in the Clean Urban
Transport for Europe programme involved in a total of five hydrogen
demonstration sites including Barcelona, Stuttgart and London. The company
is also involved in hydrogen demonstration projects in Berlin and Munich, in
Germany, a recently opened facility in Perth, Australia and launched the
world's first demonstration refueling facility at an existing retail station
in Singapore, in July.

The Los Angeles Airport project was developed by BP and Praxair, with
support from the South Coast Air Quality Management District, the DOE and
the California Energy Commission. The site has been designed to run like a
public retail site in order to enhance BP's understanding of how it might
develop solutions to supply hydrogen to existing retail stations in the
future.

In addition to the Los Angeles Airport project, BP is taking part in US
DOE-supported projects due to be run in several US states. BP is a member of
the California Fuel Cell Partnership (CaFCP) which operates a hydrogen
demonstration station in Sacramento, California.

BP supports a range of research and development initiatives aimed at
developing technical solutions to support the delivery, storage and
dispensing of hydrogen. These involve both academic institutions and private
companies and in the US include compact reformers and high pressure
refueling.

BP is a global energy company providing increasingly clean fuels to some 13
million customers at 26,000 retail sites across the world every day. BP is
the largest producer of natural gas in the US and has extensive interests in
oil and natural gas production facilities around the world. In California,
BP is home to 6000 employees and markets its retail products under the ARCO
and ampm brands.

H2H: GM Creates Hydrogen-Powered HUMMER

Unique Experimental Vehicle Will Provide Valuable Technology Learnings

LOS ANGELES - General Motors has adapted a HUMMER H2 SUT to run on hydrogen,
and will share it with the office of the Governor of California. The HUMMER
H2H will assist efforts to learn more about hydrogen storage and refueling
infrastructure development. This experimental vehicle also illustrates how
industry and government can collaborate to make fuel cell technology and
California's Hydrogen Highway Network viable.

"The H2H is a bold experiment that along with the Hydrogen Highway Network
will help California demonstrate the economic and technical viability of
hydrogen," said California Governor Arnold Schwarzenegger. "Californians
invent the future and the H2H shows that a vehicle of today can run on the
fuel of tomorrow."

The H2H is a HUMMER H2 that has been extensively re-engineered to operate on
gaseous hydrogen fuel, with its main tailpipe emission being water vapor.
The truck uses a supercharged version of the truck's original Vortec 6000
(6.0-liter V-8) internal combustion engine. The H2H is not intended for
production.

"The H2H was created for two purposes," said Elizabeth Lowery, GM vice
president, Environment & Energy. "It brings focus and attention to the
journey to a hydrogen economy, and it will provide GM with key learnings on
hydrogen storage, hydrogen delivery systems, and hydrogen refueling
infrastructure development."

Long-term vision

GM is moving very fast on reducing the cost of fuel cell stacks and proving
the technology and commercial viability of fuel cell technology. GM is
committed to perfecting fuel cells because they are more efficient and
cleaner than internal combustion engines.

"As part of our 'march toward zero' with fuel cell vehicles, we need to
learn many things about the handling and storage of hydrogen and its use as
a motor vehicle fuel," said Lowery. "We believe the H2H will improve our
understanding of using hydrogen as a motor vehicle fuel and of creating a
viable hydrogen-refueling infrastructure."

In addition to its experimental use, HUMMER will use the H2H to bring
attention to the promise of hydrogen, especially the public and private
partnerships required to create a hydrogen economy. For example, H2H will be
used to help illustrate important milestones in the development of
California's Hydrogen Highway Network, an initiative that combines the
efforts of industry and government to develop that state's infrastructure,
research and economic development efforts.

The H2H was created by a team of GM engineers from the U.S., Canada and
Germany, in collaboration with Quantum Technologies (NASDAQ: QTWW), a
California-based leader in packaged fuel systems for hydrogen and one of
GM's fuel cell technology alliance partners.
HUMMER's bold experiment
The H2H also makes a bold statement for HUMMER.

"The H2H is a bold experiment showcasing HUMMER's support for long-term
solutions to energy and environmental challenges," said Susan Docherty,
HUMMER general manager. "It is something we can do right now to help support
GM's long-stated goals of pursuing commercially viable fuel cell
technologies."

Along those lines, HUMMER fuel economy will improve in 2005. The midsize H3
debuts in the spring as an authentic HUMMER in a smaller and more
fuel-efficient package. Also in 2005, the original HUMMER, the H1, will see
a fuel economy increase of up to 15 percent with the introduction of the H1
Alpha model equipped with the Duramax diesel engine.

HUMMER H2H: Design and Technology Highlights

LOS ANGELES - The HUMMER H2H, a hydrogen-powered experimental vehicle,
combines a distinctive design with advanced technologies in order to help GM
and California gain experience and learning on the journey to a hydrogen
economy.
Design

HUMMER is like nothing else, and the H2H carries that tradition forward. Not
only does the H2H carry HUMMER's iconic design, it creates a bold and
striking visual statement on the future of hydrogen.

HUMMER designers took the opportunity to make the H2H a unique expression of
HUMMER's trademark appearance. The H2H is based on an H2 SUT (Sport Utility
Truck) body, with several enhancements. The SUT rear cargo bed is covered by
a special composite tonneau, giving the truck a "slant back" appearance. The
slant back shape is a new interpretation of a body style created for the
military HUMVEE, the precursor and inspiration for HUMMER itself.

The H2H is immediately recognized by its Laser Blue exterior paint, a rich,
deep color never before used on a HUMMER. A special graphic on each side of
the body announces the truck's hydrogen fuel application, along with
HUMMER's support for California's Hydrogen Highway Network initiative. A
special integrated roof rack and light bar sits atop the truck, with a
unique chrome grille guard on the front.

On the inside, designers again took the opportunity to integrate some
one-of-a-kind touches. These additions not only make the H2H more
distinctive, they are also styling experiments allowing designers to test
ideas that may influence future vehicles. These include special
water-resistant seats made of a prototype nylon-based material. Rather than
splattering and soaking, spilled water hits this material and immediately
gathers into droplets perched on the surface of the seat that can be easily
brushed aside.

H2H is equipped with a rear entertainment system, featuring DVD players with
screens mounted into the headrests. The headliner of the H2H is made of
Ultra-Suede, a material that is especially soft, luxurious and durable. The
instrument panel features a carbon fiber-patterned appliqué evoking the
material used for the H2H's fuel tanks.

Technology

Many worthy experiments regarding hydrogen fuel are being conducted on
smaller, less expressive and less rugged vehicles. The H2H is a rare
opportunity to apply this concept to one of the world's most rugged and
distinctive vehicles - a HUMMER H2.

The H2H features the same Vortec 6000 (6.0-liter V-8) engine utilized in all
HUMMER H2s on the road today. This experimental vehicle achieves much of the
same on-road driving characteristics and comfort of the H2, a major
accomplishment for such an advanced technological effort.

The dynamics of fuel delivery to an internal combustion engine are much
different for gaseous hydrogen fuel, compared to gasoline, due to the
different combustion dynamics of these fuels. Specially designed fuel
injectors deliver hydrogen to the engine more conservatively than in a
gasoline fuel system, thus reducing engine power. The H2H adds a
supercharger mounted onto the Vortec 6000 to help the engine reclaim some of
that deficit, reaching a peak of approximately 180 horsepower (134 kw).

The truck's powertrain, fueling and electrical systems have all been
extensively reconfigured to operate with a dedicated 350-bar compressed
hydrogen fuel system. This includes three on-board carbon fiber fuel tanks.
Two tanks are mounted underbody in the approximate location of a traditional
gasoline fuel tank. The third is mounted in the H2 SUT's rear cargo bed. The
three tanks combine to create 5.5 kg (12 pounds) of total hydrogen storage.

The H2H's hydrogen fuel system including fuel injection, electronic
controls, ultra-light composite hydrogen storage, complete with integral
pressure regulation and safety systems, was developed in collaboration with
Quantum Technologies (NASDAQ: QTWW), a California-based leader in packaged
fuel systems for hydrogen and one of GM's fuel cell technology alliance
partners. In 2002, GM acquired a substantial minority ownership position in
Quantum to collaborate on improving the range of GM's fuel cell vehicles
through the development of hydrogen storage, hydrogen handling and
electronic control technologies for fuel cell applications.

The hydrogen refueling interface for the H2H follows the prototype design
set forth in California. It consists of two connectors (one in the
traditional fuel-fill location, the other on the rear bumper) that enable
the fastest fuel fill currently available in California's growing hydrogen
infrastructure. In its early testing and development, it is estimated that
the H2H can travel roughly 60 miles (97 km) between fill-ups.

GM's foremost powertrain and vehicle development engineers in the U.S.,
Canada and Germany collaborated to create the H2H's hydrogen fuel system.
The electronics and safety systems of the H2H are state-of-the art for a
hydrogen-powered vehicle. In fact, the H2H's safety system is modeled after
that used on GM's Hydrogen3 minivan, GM's record-setting hydrogen fuel cell
vehicle.

GM is moving very fast on reducing the cost of fuel cell stacks and proving
technology and commercial viability of fuel cell technology, and is
committed to perfecting fuel cells because they are more efficient and
cleaner than internal combustion engines. Therefore, there are no plans at
GM to produce the H2H or pursue hydrogen internal combustion engine
technology long term.

BP, Praxair and Governor Schwarzenegger Dedicate First Retail-Designed
Hydrogen Fueling Station for California at LAX

LOS ANGELES, Calif., October 22, 2004 - United by a vision to support
California's commitment to cleaner energy, BP, Praxair and key stakeholders
were joined by Governor Arnold Schwarzenegger today for the dedication of
the state's first retail-designed hydrogen fueling station at the Los
Angeles International Airport (LAX).

"The opening of this hydrogen demonstration site is an important step to
meeting the future energy needs of California and recognizes the increasing
energy needs of a growing and developing State economy," said Ross Pillari,
president, BP America. "This project is an important step in developing the
future options and what we learn from this location will form the basis for
future success."

"Hydrogen presents a golden opportunity for the Golden State," said Scott
Kaltrider, Praxair vice president, North American Industrial Gases. "Praxair
is pleased to deliver the cutting-edge technology that allows hydrogen to be
produced, stored, and dispensed at a retail-designed hydrogen fueling
station."

"For the last decade, the City of Los Angeles has been proud to embrace our
responsibility to the environment by adopting clean-fuel technologies
throughout our City departments. Today we advance our commitment to
improving air quality with the opening of this new compressed-hydrogen
fueling station," said Mayor Jim Hahn.

The BP/Praxair hydrogen fueling station is a joint project among BP,
Praxair, Los Angeles World Airport, South Coast Air Quality Management
District, California Energy Commission and the United States Department of
Energy, all of which helped fund the nearly $2 million construction cost.

The BP/Praxair fueling station will be used to fuel hydrogen-powered
demonstration cars supplied by DaimlerChrysler. The 10,500 square-foot
hydrogen facility incorporates a retail-style design, which will pave the
way for future retail outlets.

At the BP/Praxair station, hydrogen is produced on-site by applying
electricity to water, which separates hydrogen molecules from oxygen
molecules. The oxygen molecules are vented to the atmosphere and the
hydrogen gas is compressed and stored. Stuart Energy was chosen by Praxair
to supply the hydrogen-generation module which produces 24 kilograms per day
of pure hydrogen fuel.

The new hydrogen station advances Governor Schwarzenegger's California
Hydrogen Highway Network, which is an initiative to support and catalyze a
rapid transition to a clean, hydrogen transportation economy in California.
