BMW greenwashing? Do they really make a pollution consuming engine?
Filed under: Hydrogen, BMW, SAE World Congress, USA

When we first heard about the new mono-fuel BMW Hydrogen 7, we were rather impressed by the extremely low emissions numbers posted by the model when tested at Argonne National Laboratory. The fact that BMW was able to reduce the emissions, boast better range and make more power as compared to their previous-generation Hydrogen 7 was pretty cool. According to Dr. Thomas Wallner, lead engineer in Argonne's hydrogen vehicle testing activities, "[The Hydrogen 7's] engine actively cleans the air. Argonne's testing shows that the Hydrogen 7's 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."
So, because air is required for the hydrogen combustion, and there are pollutants already present in the air, at times the exhaust from the BMW is cleaner than the air it took in. Does that warrant BMW referring to their hydrogen-burner as a "pollution-consuming internal combustion engine?" Perhaps we're just picking nits, but that sounds a wee bit like greenwashing. It's not like the overall air is cleaner after going through the system, after all. Read their entire press release after the break.
