BMW announces its latest milestone in its pursuit of the hydrogen
future, the BMW Hydrogen 7 mono-fuel. Based on the BMW Hydrogen 7
bi-fuel version (gasoline and hydrogen), the mono-fuel vehicle's
internal combustion engine is optimized to run solely on hydrogen and
shares the performance, comfort, and safety qualities of every
production BMW 7 Series. The BMW Hydrogen 7 mono-fuel will be featured
at both the 2008 National Hydrogen Association Conference in
Sacramento, CA (Mar. 30 - Apr. 3) and the 2008 SAE World Congress in
Detroit, MI (Apr. 14 - 17).
The BMW Hydrogen 7 mono-fuel is equipped with a V12 internal combustion
engine (ICE) which has been engineered to run exclusively on hydrogen .
Compared with the bi-fuel version, this vehicle achieves incredibly low
emissions, increased engine performance, reduced consumption and
"The mono-fuel Hydrogen 7 is the of more than 25 years of hydrogen
development by BMW," noted Tom Baloga, Vice-president of Engineering
for BMW in the US. "It demonstrates BMW's support for a hydrogen
infrastructure by producing an internal combustion engine that produces
truly near-zero emissions and simultaneously cleans the air of certain
In BMW's view, hydrogen is the most logical energy carrier of the
future for three reasons. Firstly, it has no carbon and therefore emits
no CO2, HC's and other pollutants. Secondly, it can be produced using
renewable, clean technologies like solar, wind, geothermal, and
bio-processes. Lastly, it can be produced in stable areas of the globe
as necessary for energy security. Although today's hydrogen is mainly
derived from natural gas, hydrogen can and will be "green" from
renewable and clean sources in the future. Unlike batteries, which will
likely also play an important role in future transportation, hydrogen
vehicles can be refueled rather quickly for long trips, don't require
powerlines across the landscape, and hydrogen can be generated and
stored 24/7 when wind is greatest or electrical demand is low.
The BMW Hydrogen 7 mono-fuel is a demonstration production vehicle, not
a prototype. It was created to showcase the zero CO2 and low emissions
potential and feasibility of a dedicated hydrogen internal combustion
engine (ICE). In addition, the BMW Hydrogen 7 mono-fuel helps deliver
additional experience in the everyday use of hydrogen beyond what has
already been learned with the nearly 100 bi-fuel Hydrogen 7 Sedans that
have been used in a customer test drive program since November 2006.
The Hydrogen 7's V12 mono-fuel ICE produces no CO2 and near-zero
emissions, while not sacrificing performance. In fact, the tailpipe
emissions are so infinitesimal they pushed the limits of current
emission testing technology.
Independent authorities, including the Argonne National Laboratory
(ANL), have confirmed these results. ANL conducted emission tests on
BMW Hydrogen 7 mono-fuel vehicles in early March 2008.
"The BMW Hydrogen 7's emissions were only a fraction of SULEV level,
making it one of the lowest emitting combustion engine vehicles that
have been manufactured," said Thomas Wallner, a mechanical engineer who
leads Argonne's hydrogen vehicle testing activities. "Moreover, the
car's engine actively cleans the air. Argonne's testing shows that the
Hydrogen 7's 12-cylinder engine actually shows emissions levels that,
for certain components, such as Non Methane Organic Gases (NMOG's) and
Carbon Monoxides (CO's), are cleaner than the ambient air that comes
into the car's engine."
BMW and ANL will hold a joint press conference about the
ground-breaking results at the SAE World Congress. Christophe Huss,
Vice-president - Development Abroad, Type Approval and Traffic
Management for BMW will be present at the SAE World Congress.
