BMW has been
leading the charge into the Hydrogen economy for several
years. Four years ago, a fleet of hydrogen-powered
vehicles set off on a trip that didn't end for eighteen
months, spanning the world. The goal - to introduce
the new breed of motor vehicle to thought and political
leaders around the world.
When the first
BMW test vehicles were driven twenty years ago, nobody took
any notice. This changed with the BMW CleanEnergy World
Tour: now the BMW hydrogen fleet is a hot topic. Presented
for the first time at the EXPO 2000, the BMW 750hLs have
covered 170,000 km (100,000 miles) on roads all around the
world without any problems, providing impressive evidence of
their everyday utility value. In Berlin, Brussels and Milan,
Dubai, Los Angeles and Tokyo they demonstrated what the
future of environmentally compatible mobility will look
like.
An entirely new
infrastructure is necessary for the creation, distribution
and use of hydrogen, and it is an issue of interest to more
than just the economic and industrial powers in the world.
The most important contribution politicians could make is to
create a secure legal framework which facilitate the
introduction of the new energy source and which make
hydrogen a viable fuel for all.
A brief
comparison illustrates the point: the first petrol filling
stations were built in the early twenties in Europe; a fully
extensive network was not established in rural areas until
the fifties. The change to hydrogen will take time, other
strong partners and financial commitment. But these high
investments will pay off: with an energy source which never
runs dry and which does not harm the environment. The BMW
CleanEnergy World Tour proves it. The Hydrogen Age has
begun.

The principle is
straightforward: water is split electrolytically into its
two components hydrogen and oxygen. The energy required for
separating the two elements is transferred to the hydrogen.
Hydrogen is thus an energy carrier and not an energy source
such as petrol for example. When hydrogen is combusted with
oxygen in the air, this energy is released to drive the
engine and what remains is water.

Hydrogen will
replace petrol. That is the BMW CleanEnergy idea. However,
since hydrogen fuelling facilities are not widely available
at the moment, the BMW CleanEnergy vehicles are fitted with
a petrol tank in addition to the hydrogen tank. If one of
the tanks is empty, the vehicle automatically switches to
the other. This what is known as bivalent and it is the
decisive advantage for the fast introduction of hydrogen
vehicles.
Establishing
hydrogen as a fuel worldwide is set to challenge a whole
generation. Now that hydrogen technology has already reached
an advanced stage, it is necessary to build up an
infrastructure based on global partnerships and to create
the political conditions for lasting energy supply.
Count on BMW to be a leader in this quest. |
