BMW and hydrogen.Follow

BMW has produced an experimental hybrid vehical that runs on gas or hydrogen. not a hydrogen fuel cell vehical, but a hydrogen powered internal combustion engine. the engine will run on both regular gasoline or hydrogen.

they used a 3 series platform. the compressed hydrogen tank is in the trunk.

it can be done.

OK, Im now taking bets on when the oil companies will buy out BMW for making a car that could run on hydrogen.

BMW isn't the only company that has constructed a hydrogen powered automobile. Just about every automobile manufacturer has made a prototype or 3 for hydrogen motorcars. The problem with hydrogen automobiles is the inherent flaw of hydrogen, ergo volatility. The flash point of hydrogen is much lower than that of traditional gasoline. Though safty stardards are far less in many places in Europe. The United States will never knowingly allow a motorcar that could very well spontaneously explode. The Ford Corperation went under a lot of law suits due to the Pinto models.
The next flaw with hydrogen motorcars is refueling stations. Which would also be heavly scrutinized for safty regulations. As far as I know, not just anyone is allowed to handle hydrogen in its gas or liquid state. I am almost certain it requires a license of some sort.

Yeah. It's not that the tech hasn't been available for awhile. It's the cost to use it safely that's an issue (or even whether it can *ever* be used safely). You're essentially driving around with a compressed container of highly explosive gas in your trunk. Gasoline will combust, but only under rare conditions will a tank of gasoline actually explode (despite what you may have seen in the movies). Not so with hydrogen. After all, they make bombs out of them... ;)

Well despite no link to the Hydrogen BMW yet it's definately something that can be done and done safely. I mean if they have made a prototype now, easily this means we won't see it for 5-6 years after the rigorous safety tests it's put through. Regarding the gas/oil companies buying this up, will never happen as long as it's a European or Japanese automotive maker, simply because they do not want any foreign control over their profit abilities. Sure they could get some ludacris amount of money to purchase this and keep it under wraps, but in the same light these cars would easily sell out much faster and be much higher revenue generators than any oil company could attempt to produce.

Thats the problem with Ford,Chevy and Chrysler auto lines, most of their funding when not out of pocket comes directly from the oil/gas companies. The only reason Ford came out with the Escape Hybrid was to show the public an American Brand can do an SUV that is gas/electric, however though it's now coming to light that it's estimated MPG rating may be incorrect.

I think the hearts of the BMW engineers are in the right places, unfortunately I don't think their Minds are.

The problem with a hydrogen car isn't the feasibility of making an engine run on it...as stated already.

It's all about making it both safe AND convenient. Compressing hydrogen into tanks to run automobiles is neither of these things.

Hell, you can run a car off a dozen different fuels and types of energy, but you have to make it very idiot resistant before it can be widely marketed. Why? Because every a$$hole in America is going to own one. And these are the same people who regularly nominate themselves for Darwin Awards.


It's bad enough that I have to be on the road with you idjits, I don't want you driving bombs. Nor do I want to be anywhere near the Raceway when some jackass tries to refill his tank for the first time and dumps the contents for a nice big fireball.

Huh!? Totally wrong. First off, it's not "cheaper" in any real way. The selling point for hydrogen is that it's renewable. You can create it from normal water via electrolisis (separating the hydrogen and the oxygen). And it does burn clean. However, it costs more electricity to generate the hydrogen then you generate going the other way. In any closed physic system, there is inefficiency, so this is always true (and when it's not, it's because you are introducing something non-renewable into the system and not accounting for it somehow).

Thus, we have to spend more "work" creating the hydrogen to put in the tank, then it currently costs to simply put gasoline in that same tank. The advantage is that we've moved the polution from the tailpipe to the powerstation (or hydrogen generating station if you will), where it's presumably easier/cheaper to put in effective pollution safeguards. In every other way, it costs more.

I also think you totally don't understand the difficulties involved in making this usable for the general public. There are currently *zero* publically accessable hydrogen fueling stations (only ones in existences are at the same prototype facilities being used to test the cars). Hydrogen is not like natural gas. It can't just be piped in. It has to be transported in tanks (just like gasoline really). We have currently *zero* infrastructure to do that. We have no filling station pumps (those will have to be designed and built). We have no filling station storage tanks (those will have to be built as well). The costs to do this are *huge*, so private companies will balk at doing it. And the first family that's burned to a crisp when their car explodes will cause any funding for this to vanish really fast.

Don't get me wrong. It's a workable solution. But there are a huge number of hurdles to get over. Until they can make it safe enough for storage, transport, and use in the cars, it's not going to get off the drawing board. It's not about rigorous saftey tests. You speak of it as though you just spend some time and a solution magically appears. Hydrogen is an extremely combustable gas. It's a very low density gas (it's number "1" on your periodic chart in case you flunked chemistry), so it must be stored under high pressure to be usable (or you'd have a gas tank the size of the Hindenburg to run your car). Combustion + compression == explosion... We're not just figuring out how to make some safety feature work better. You've got to solve a very fundamental physical problem based on the properties of the material you are using. That's not something that'll be fixed by running a few tests.

Huh?! Talk about rhetoric. Car manufacturers are private businesses. Their "funding" comes from the sales of their cars. It's not like Exxon slips Ford a few million each year to keep their cars running on gasoline. Exxon might very well lobby government regarding regulations for cars, but they don't control any sort of funding for the car manufacturers themselves. Ford will make a hydrogen powered car the day it becomes economically feasable to do so.


EDIT: I can't believe I tossed out such an obvious "floater", and no one called me on it! You guys are slacking...

To add:

Why Oil Companies could care less about hydrogen automobiles.

Even if a company could mass-manufacture a hydrogen powered automobile that was completely safe, you still run into one fundamental flaw. This would be 'new' technology availible to the public. New technology tends to be very expensive. I assure you if these motorcars were to be made to the public, your average Joe will not be able to afford it. Simple reason being is the block of the engine would require expensive to make alloys that could withstand the intense heat that is produced while burning hydrogen. Not to mention a state of the art cooling system. Maintence on such a system would also be very complicated. Car mechanics would quite literally need to have degrees in engineering to work on these automobiles. Any maintence/parts would be extremely costly. This kind of product would be really hard to sell just based on that. Also, reguardless of how safe you actually made these automobiles, most would still not trust not only their lives, but also the lives of their children, and loved ones on a "gas tank" full of a fluid or gas that is so volatile that simply shaking it too much could cause an explosion of weapon-esque proportions.
Even if this caught on, there are so many other mediums that will always require petrolum based fuels.

Trucking Industry- If I had to guess there are at least 4-5 cars to one truck. That being said, the average driver of a car will spend anywhere from 30-90 on a tank of gas a few times out of the month. Truck drivers will spend literally hundreds of dollers multipule times in a week on gas.
Trains-This would probably be one of the last of the transportation industry that would upgrade to hydrogen, suggesting it ever did.
Airline/Air transportation- Many aircraft flown by commercial airline companies are older than pretty much any poster here. Aircraft built in the early 70's and such. That said, this would also be slow to catch on.
Military- This ties in with airline companies. The DoD will not scrap billions worth of aircraft, Ships, tanks, and GOV's just because some new technology came about. Lastly, some military technology you simply do NOT want to use hydrogen on. Imagine an aircraft carrier powered by hydrogen. Or even a smaller ship like a frigate.
Shipping-Like above. I wouldn't want to be on a rocking cargo ship full of hydrogen. Nor would I want to transport any of my goods on a huge catastrophe waiting to happen.

Oil companies might lobby against it now, but they are the prime canadites to start making an alternative fuel as well. Simply because they have the resources to do so. So the same company that was charging you $3/gallon for gasoline, will now charge you $5/gallon of liquid hydrogen. Also, everyone of your workers to make your hydrogen would quite literally be chemists and engineers. Not exactly cheap labor. Sure over time the costs would subside, but that doesn't mean the "hydrogen" companies would make their product any cheaper at the pump. Probably 1/2 of all oil company profits are generated by commerical and military. I wouldn't doubt it one bit. Hell 1/2 is probably an underestimation.

In short, I do not believe these theories that the oil companies are buying out hydrogen technology as I don't see how hydrogen technology is a threat to the oil industry. In 100 years, yeah I could see a threat, but today it isn't a threat. Why would they spend millions lobbying against something that isn't all that feasible in the next 50 years.

I see electric as having a far better potential than any combustion engine, no matter what it's burning.

Hydrogen's appeal is the renewability. I believe we'll reach our next big leap in automobiles when we have all electrically powered components and some sort of onboard power generation from a renewable source that will allow continuous operation. Our thinking is changing in good ways (regenerative braking), but we still have a long ways to go before we find a way to leap that next hurdle.

NYC currently runs about 400 CNG or Clean Natural Gas buses, and has been doing so for about 3-4 years. No explosions so far. Methane is almost as explosive as hydrogen.

Flash point of Hydrogen is -423°F/-252.78CSource

Flash point of Methane is -306.40000000000003F/-188ºc Source

Absolute Zero is -459F/-273C.

The flash point of Hydrogen is just barely above Absolute Zero. For those of you who failed at school, Absolute Zero is the coldest it can ever be. As heat is simply atoms oscillating and at that temprature, atoms oscillate at the slowest rate possible and thus no heat. Also note that completely stoping oscillation is impossible.
The main difference between methane and hydrogen is that methane needs far more oxygen to burn as it is a compound and is not heated up as it is sprayed through a nozzle. Hydrogen requires far less oxygen and heats up by simply going through a nozzle(as such as a fuel injector). Therein lies the fundamental flaw in hydrogen in automobiles. Simply shaking hydrogen will cause it to heat up with even the slightest amount(on an atomic level) of oxygen will cause an explosion. If even just a few oxygen atoms exist in a hydrogen tank. Space Shuttles have met this problem many times. An oxygen leak inside a hydrogen cell is what causes many space shuttles to explode.
