BMW Hydrogen 7 Has Super Duper Low Emissions
Independent tests conducted by engineers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory on a BMW Hydrogen 7 Mono-Fuel demonstration vehicle have found that the car’s hydrogen-powered engine surpasses the super-ultra low-emission vehicle (SULEV) level, the most stringent emissions performance standard to date.

“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.”

It was not an easy task to measure the Hydrogen 7’s emissions. “A gross polluter is easy to measure, but the cleaner the car the harder it is to test,” said Don Hillebrand, director of Argonne’s Center for Transportation Research. “Most labs test at the SULEV level. Argonne’s vehicle testing facilities are unique in that they are able to detect even trace levels of emissions. In this case, it was near-zero emissions.”

After an extensive evaluation by BMW, “Argonne’s Advanced Powertrain Research Facility was found to be the only public test facility in North America capable of testing hydrogen vehicles at these low emissions levels,” said BMW’s Wolfgang Thiel, manager, operating support emissions analysis. “Zero is a very small precise number — we are pushing the boundaries of emissions testing.”

Technical and program information about the Hydrogen 7 tests will be presented by Wallner and BMW North America’s Jason P. Perron Wednesday, April 2 during the National Hydrogen Association Annual Hydrogen Conference, March 30-April 3, in Sacramento, Calif. Argonne will join BMW’s Christoph Huss, senior vice president, science, traffic and vehicles regulations, in a press conference to present the test results during the Society of Automotive Engineers 2008 World Congress, April 14-17, in Detroit.

BMW has put the hydrogen model into limited series production. Although the vehicle is not yet available for sale to the general public, it is being made available to “influential public figures,” whose use demonstrate a new era in clean energy, BMW has said. In the meantime, the greatest challenge to widespread use of hydrogen cars is the limited number of hydrogen refueling stations.

Argonne has conducted cutting-edge transportation research for more than 30 years and employs a multidisciplinary staff of engineers and scientists involved in engine, battery, fuel cell, vehicle systems and applied materials research.

Argonne’s transportation research program and facilities are primarily funded by DOE’s Office of Energy Efficiency and Renewable Energy, which supports the development of vehicle technologies and alternative fuels to reduce greenhouse gas emissions and dependence on foreign oil, and enables the U.S. transportation industry to sustain a strong, competitive position in domestic and world markets.

It may not stay that way. Technology may reach a point where hydrogen can be produced efficiently enough to be a viable motor fuel. The Hydrogen 7 isn't meant to be a commercial product at this time, but more a demonstration of what is technologically possible. I wouldn't call it a "stunt".

Where does electricity come from GoObama?

Sure it can be made using wind or solar power, but If you know anything about technology, those sources are very expensive and inefficient right now and caly be used in certain parts of the world. So where else does it come from? Nuclear Power Plants, by burning Coal or Oil/Natural Gas, and etc.

I don't know about you but that makes electricity not as clean as you might think.

I'm not saying Hybrids aren't good, what I'm saying is that the process of making anything from Diesel to Hydrogen, to Electricity always creats some polution all by itself. Even creating Gasoline makes polution.

You know, after I read about the ls hybrid, I thought something similar....

HAHA yeah right I dont think so

Nice PR marketing stunt by toyota though.


What they forget to mention, is that the hybrid is so heavy and drinks down so much gas, you might as well drive a ls460.

What, no defense of its pathetic gas mileage or full-size SUV curb weight? You're slipping.

You can toss out all the toyota press releases you want, it's all marketing BS. This big pig is just as much a strain as a regular gas powered lux sedan and makes no sense at all.

A Hydrogen powered engine has low emissions!

Well gooooooooolllllllyyyyyyyy (if your old you know who said that)

Sorry but an article like this deserves sarcasm.

No they seriously thought this was news around here, huh. Unbelievable. How much did the BMW PR folks, I mean Argonne Lab, pay for this study????? How 'bout studying the emissions from the gas portion of the engine, since that is what people will be cruising around using when they cant refuel their initial tank of hydrogen.

Super Duper - what are we, in 5th grade?

But yes, great news for BMW... Hydrogen power is great, and US has the biggest stock pile of Hydrogen in the world, so it should be easy selling it in the US. the only thing is, will the infrastructure of hydrogen pumps follow quick enough?

According to my feelings between round about 30 and 40 dgrees Celsius (depends on outside and engine temperatures). I had my hands near the exhaust pipe, and they become wet like if you put them in "cold steam", unbelievable. You can actually wash your hands underneath there.

"BMW Hydrogen 7 Mono-Fuel demonstration"

Holy crap, you mean if you don't burn gasoline, it doesn't create toxic emissions. It's a good thing someone decided to research and confirm that for BMW's flock.

Nice marketing promo, maybe next time they'll try using some gasoline to see how clean that V12 is.

MDi's air car doesn't create emissions either, I think someone should research that.

it guzzles gas and hydrogen like the V12 it is, but makes the horsepower of a V6

actually the reason behind having more cylinders is to be able to bring more displacement to the engine. hydrocarbons such as petroleum, diesel or ethanol simply have more energy packed within its c-h single and double bonds and thus make more energy, duh!

so for liquid hydrogen to make half the power of petroleum makes perfect sense.

Whose to say that none of the other Plebeian manufacturers don't already have a hydrogen plan? This may strike that, will be end run technology...I think its great to have choices in the mean time. Nothing that will shock the world economic setup. Its all good.

What? Any fool can light a match and find out that hydrogen+oxygen burns (think hindenburg) which is the basis of BMW's R&D.
The FCX has about 2x the range of BMW's hippo and saves a lot of weight by not having to lug around a V12 and a 2nd gas tank which incidentally eats into trunk space (Autobilde would not be amused).
The BMW 7 was designed purely so BMW can say they were first.

As for what I drive, I can't believe you don't know. Ask any other posters on here, they'll know. I drive a vehicle with real heritage and a name that represents something (BMW wouldn't have a clue what this means), that is until the Germans got their hands on it and diluted the brand all in the name of selling out.

hydrogen and oxygen burns, oh really? maybe you should fill your gas tank with hydrogen and see what happens, seeing how you've figured out the great secret of combustion. or better yet, try pouring gasoline into the fcx and see what happens :D

i think huu76 drive a model t, which explains his obvious obsession to "real" heritage lol

valium,
I think you'd better go back to public school. Hydrogen fuel cells are a little bit trickier to make than simply throwing hydrogen/oxygen into a cylinder.

2H2 + O2 = 2H2O + ENERGY

You seem to have forgotten that energy is created when hydrogen and oxygen come into contact. "Burning" may not be the best terminology for the chemical reaction, but most people will get the idea if you tell them its in an ICE.

obviously the reaction is exergonic, otherwise it wouldn't make energy duh! combustion utilizes the exothermic property of the reaction whereas fuel cells utilizes the electric potential of the spontaneous reaction. enthalpy actually decreases the efficiency of hydrogen fuel cells etc etc.

actually your half assed equation, despite being balanced, shows nothing different between a simple combustion of hydrogen/oxygen and the redox reaction of hydrogen fuel cell. you might want to go back and add a catalyst and a few electrons and show the intermediate products.

if "burning" or combustion is not the best terminology for this reaction, i don't know where you learn your chemistry from.

hydrogen and oxygen coming into contact is hardly the description of the processes involved. you're forgetting a lot of details so maybe you should go back to school. obviously you don't know how complicated hydrogen combustion engines are. oxygen represents only 21%. unwanted combustion would produce nitrogen oxides and unburned hydrocarbons (from internal lubricants). so for air coming out of the exhaust of bmw 7 hydrogen to be cleaning than air we breath is quite remarkable to say the least. nitrogen oxides and hydrocarbons represent less then 0.05 percent of the air we breath. so you're pretty ignorant to call bmw's efforts a child's play.

btw, who's valium? :D

At this time, this car, like every other "hydrogen as a fuel" concept car, is nothing more than a design exercise. All these guy have built a car that runs on a non-existent fuel supply.

Yes, hydrogen abounds throughout the universe, but so far, man has not figure out how to cheaply and cleanly extract it, concentrate it, and put it into a form that can be used as fuel by these cars. And the best of science says they don't have anything even close to making this a reality. This is a cosmically huge shortcoming for hydrogen cars, I would say.
