Testing on BMW’s Hydrogen 7 Mono-Fuel prototype by the U.S. DOE has concluded that the hydrogen-powered engine surpasses the most rigorous of emissions performance standards. The BMW finds itself beyond the super-ultra low-emission vehicle (SULEV) level.

“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, are cleaner than the ambient air that comes into the car’s engine.”
