* A cooperative project of the companies OMV, Linde, and
Daimler subsidised by the State of Baden-Württemberg
* A hydrogen filling station with new filling technology for
enhanced user-friendliness and extended operating range
* Use of hydrogen in fuel-cell technology for
environmentally friendly vehicle generations

Stuttgart, 17 June 2009 - On the site of the OMV service station at
Stuttgart Airport, OMV in cooperation with Linde AG and Daimler AG is
opening Baden-Württemberg's first publicly accessible hydrogen
filling station on 17 June 2009. This successful cooperation between
the participating companies is subsidised by the State of
Baden-Württemberg. The project is centred on the use of hydrogen as
an environmentally friendly energy carrier. Hydrogen filling stations
represent an important step toward reducing dependence on fossil
fuels in the long term and are a step closer to emission-free
sustainable mobility. The innovative hydrogen filling station will
serve fuel-cell vehicles of the latest generation, such as the
Mercedes-Benz B-Class F-CELL, with 700-bar high-pressure technology.
Small-series production of this vehicle is to commence later this
year in Germany.

The proximity of the OMV service station to Stuttgart Airport - a
major transport hub - and to Daimler AG's research and development
centres, together with the cooperative contact between the two
companies, is providing the basis for the establishment of
Baden-Württemberg's first publicly accessible hydrogen filling
station. Within the framework of a public-private partnership, the
hydrogen station will provide an important impulse for a future
supply network for this German federal state, thus supporting the
operation of local emission-free electric vehicles on the basis of
fuel-cell technology.
"The development of new drive technologies is crucial to
Baden-Württemberg's automotive industry and will ensure that it can
emerge with renewed strength from the current crisis and participate
in the race for international technological leadership. Hydrogen
technology plays a decisive role here. By entering the field of
hydrogen technology we are protecting natural resources, while at the
same time reducing our dependence on the import of fossil fuels. This
initiative is a key component of Baden-Württemberg's sustainability
strategy: by utilising energy in a future-proof way, we are promoting
environmentally friendly and thus sustainable mobility," said
Baden-Württemberg's State Premier Günther H. Oettinger of the joint
project. The federal state was therefore supporting this project with
the sum of EUR 800,000 from the programme "Zukunftsoffensive
Baden-Württemberg" (Baden-Württemberg's Campaign for the Future),
Oettinger continued.

As a leading gas supplier and the world's largest manufacturer of
hydrogen facilities, Linde has a wealth of expertise throughout the
hydrogen value-creation chain - from hydrogen production to filling
technology. This company, the world's pre-eminent outfitter of
hydrogen filling stations, distributes filling technology in 15
countries. The new hydrogen station at Stuttgart Airport incorporates
ion-compressor technology developed by Linde. With this new
compression process, cars and electric buses powered by fuel cells
can be refuelled within a matter of minutes - just like vehicles
powered by conventional internal combustion engines - with hydrogen
at a pressure of either 350 or 700 bar. The gaseous hydrogen is also
supplied by Linde AG. Operation with hydrogen produces only
electrical energy along with water vapour. No hydrocarbons or sulphur
oxides are generated - and not even carbon dioxide (CO2), which
arises during combustion of fossil fuels. Hydrogen as a fuel for
automotive drive technologies is free of emissions detrimental to the
climate and to the environment in both its production from renewable
energy carriers and in its transformation into electricity. "As the
pioneer of hydrogen technology we have a particular responsibility to
press ahead toward hydrogen-based sustainable mobility," said Dr Aldo
Belloni, member of the Executive Board of Linde AG. "Establishing the
infrastructure for this future-oriented energy carrier calls for a
concerted effort among the partners involved. We are delighted to
have realised a filling-station concept of the latest generation
together with OMV. With our newly developed 700-bar technology,
vehicles can be refuelled rapidly, safely and in a user-friendly

"Our fuel-cell vehicles have already demonstrated their suitability
for everyday operation. To turn emission-free driving into reality,
we now need a comprehensive network of hydrogen filling stations,"
said Dr Thomas Weber, member of the Board of Management of Daimler AG
with responsibility for Group research and Mercedes-Benz Cars
development. "We therefore wholeheartedly welcome and support the
initiative of OMV." Daimler already presented the first fuel-cell
vehicle in 1994; the Group has since invested more than EUR 1 billion
in fuel-cell development. With more than 100 test vehicles and around
4.4 million kilometres covered, the Stuttgart carmaker has one of the
largest fuel-cell fleets in the world. The start of small-series
production of the B-Class F-CELL, planned for 2009, is now continuing
the success story of this drive concept.

OMV operates around 400 filling stations in Germany, with a clear
focus on the south of the country with the two federal states of
Bavaria and Baden-Württemberg, along with further filling stations in
the states of Thuringia and Saxony. The hydrogen filling station
project at Stuttgart Airport is the first of its kind in Germany for
OMV. "OMV is already intensively dealing today with the mobility of
tomorrow. In our function as energy providers we have a
responsibility with regard to the fuels of the future. Hydrogen,
currently in the development and testing phase, is one of the
possible alternatives for the mobility of the future," said Dr
Gerhard Roiss, deputy chairman of the Executive Board of OMV
Aktiengesellschaft. "We are therefore very happy to be able to
support Daimler's research and development activities with our new
hydrogen filling station, together with the State of
Baden-Württemberg." The project is being supported by the OMV Future
Energy Fund, established in June 2006 as an independent organisation
for the financial support of projects for renewable energy forms,
with a contribution of more than EUR 100 million. With HyCentA
(Hydrogen Centre Austria), a further project of OMV with headquarters
on the campus of the Technical University of Graz, the energy
supplier has long since been gathering invaluable experience in the
future-oriented field of research and development with hydrogen

Further background information

Hydrogen production:
The hydrogen required for the filling station is generated in what is
known as the steam-reforming process: In the steam reformer,
hydrogen, carbon monoxide, and carbon dioxide are initially produced
at high temperatures from natural gas and water vapour in a reactor.
In the following stage, steam is added to convert the carbon monoxide
into carbon dioxide and hydrogen.
The hydrogen fuel derived by this means already leads to carbon
dioxide savings of up to 30 percent, as compared with modern diesel
vehicles (basis of comparison 120 g CO2/km). Nevertheless, in the
medium to long term, there will be no substitute for hydrogen
production from renewable energy sources. The Linde Group is
currently carrying out intensive work on innovative solutions for
sustainable hydrogen production. An important step towards the
marketable production of regenerative hydrogen has been reached with
a new process for deriving hydrogen from biogenic raw materials. For
this purpose Hydromotive GmbH, a subsidiary of The Linde Group, will
establish a demonstration unit for the production of hydrogen from
glycerine in Leuna, Saxony-Anhalt, in the middle of this year.
Glycerine, a by-product arising in the manufacture of biodiesel, can
therefore be put to practical use. The hydrogen generated this way
generates carbon-dioxide savings of up to 90 percent compared with a
conventional drive unit.
Further approaches to regenerative production, such as hydrogen
production from wind and solar energy through electrolysis, or
biochemical and thermo-chemical generation from algae, are also being
pursued by The Linde Group; these are promising prospects as long as
the local conditions are appropriate.
In a project not connected with Linde, the State of Baden-Württemberg
has also promoted the development of gasification technology and will
be subsidising a demonstration unit near Geislingen as of 2010. In
this unit, biomass - for example scrap wood - is gasified in the AER
(absorption-enhanced reforming) process to yield a gas with very high
hydrogen content.

Fuel cell operation:
The B-Class F-CELL is fitted with a fuel-cell drive unit of the
latest generation and is thus both far more compact and more powerful
than previous fuel-cell systems. The newly devised stack, although
around 40 percent smaller, has a 30 percent higher output; with a 16
percent lower consumption, this unit is highly efficient. The B-Class
F-CELL also has favourable cold-starting ability. This is made
possible by innovations such as the electric turbocharger for air
supply and the new moisturising and de-moisturising systems. The
electric motor develops a peak output of 100 kW/136 hp and a maximum
torque of 320 newton-meters. The B-Class F-CELL thus fulfils high
driving dynamic requirements that exceed the level of a two-litre
gasoline car, and attains an operating range of up to 400 kilometres.

The functional principle of the proton exchange membrane fuel cell
The fuel cell is a galvanic cell that converts the reaction energy of
an introduced fuel (e.g. hydrogen) and an oxidant (e.g. atmospheric
oxygen) into electrical energy. A fuel cell is not an energy storage
medium like an accumulator battery, but an energy converter. The
proton exchange membrane fuel cell normally uses hydrogen as an
energy carrier and attains an efficiency factor of around 60 percent.
The key element of the PEMFC is a polymer membrane that is permeable
only to protons (H+ ions), the so-called proton exchange membrane
(PEM). The oxidant, usually atmospheric oxygen, is thus spatially
separated from the reducing agent, hydrogen. The fuel, in this case
hydrogen, is catalytically oxidised at the anode and releases
electrons to form hydrogen ions (protons), which pass through the ion
exchange membrane into the chamber with the oxidant. The electrons
flow out of the fuel cell via an electrical consumer, e.g. an
electric motor, to the cathode. At the cathode the oxidant, in this
case oxygen, on binding the electrons is reduced to anions, which
react directly with the hydrogen ions (protons) to produce water.
Along with electrical energy this reaction also generates heat, which
can be used for example to heat the vehicle.

The hydrogen filling station structure in Germany:
The establishment of a public hydrogen infrastructure is crucial to
the successful introduction of hydrogen-powered vehicles. The first
centres ("clusters"), such as those in Berlin and Hamburg, have
already been established. Of the currently nearly 30 hydrogen
stations in Germany, six are integrated into public filling-station
operations. Germany is thus the European pioneer. The cooperative
project being carried out at Stuttgart Airport's OMV filling station
is now Germany's seventh publicly accessible hydrogen station and the
first in the State of Baden-Württemberg.
Operation of public hydrogen filling stations will only become
economically viable once a sufficient number of hydrogen-powered
vehicles are on the roads. Achieving a broad-based market
introduction and establishing a public infrastructure will require a
coordinated, cooperative and long-term three-stage approach involving
all interest groups.
First: Focused cluster formation - demand-based grouping in urban
areas for technically and economically appropriate capacity
utilisation. Five to ten filling stations are already sufficient to
cover the initial requirements of a large city.
Second: Corridors - connecting the urban clusters by means of
corridors along the main arteries. Here, too, initial plans have been
drawn up, e.g. for linking the Berlin and Hamburg H2 clusters along
the autobahn.
Third: Comprehensive area coverage.
