BMW has announced its latest milestone in its pursuit of the hydrogen future, the BMW Hydrogen 7 mono-fuel, featuring an internal combustion engine in the BMW Hydrogen 7 mono-fuel that produces near zero emissions while, at the same time, combusting ambient air pollutants. Based on the BMW Hydrogen 7 bi-fuel version (gasoline and hydrogen), the new 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. One of the BMW Hydrogen 7 mono-fuel vehicles is featured in the BMW Booth at the 2008 SAE World Congress being held this week in Detroit.
The BMW Hydrogen 7 mono-fuel is equipped with a 6.0-liter internal combustion engine (ICE) which has been engineered to run exclusively on hydrogen. This vehicle achieves near zero emissions, excellent engine performance, reduced fuel consumption and greater range compared to the bi-fuel Hydrogen 7. Since the consumed hydrogen has no carbon, the engine itself would produce no CO2, hydrocarbons, or other pollutants; however, the existing pollutants in the surrounding air are consumed by the engine, plus minute amounts of lubricating oil. The result is virtually undetectable exhaust emissions. New procedures for exhaust gas measurement and analysis, therefore, had to be developed together with experts at the Argonne National Laboratory, the only test laboratory in the USA capable of measuring such minute emissions.
"The mono-fuel Hydrogen 7 is the result of more than 25 years of hydrogen development by BMW," noted Tom Baloga, Vice-President of Engineering for BMW in the U.S. "It demonstrates BMW's support for a hydrogen infrastructure by producing an internal combustion engine that produces truly near-zero emissions while simultaneously cleaning the air of certain pollutants."
