BMW Hydrogen 7 tests below SULEV levels

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

note it's an H2 ICE not a fuel cell.

well arent all hydrogen cars below sulev, if water vapor comes out of the exhaust pipes?

Yeah... I always thought hydrogen cars are practically ZEVs, with the only "emission" being water vapor, hardly a pollutant.

2H2 + O2 -> 2H2O

The hydrogen 7 gets like 5mpg on hydrogen. 5 miles per gallon of liquid hydrogen. Horrible. It runs better on gasoline at around 17mpg.

Hydrogen-electric hybrids FTW.

hydrogen FTL, terrible energy density

Hydrogen FTL indeed.

The amount of electricity that is used to produce hydrogen, it would be better off to use this electricity directly to power the car.

Better yet, the amount of oil or coal that is burned to produce this electricity makes these low emissions an oxymoron.

once a lightweight, fast charging, long lasting, high capacity battery comes out, it will be the end of hydrogen cars. An electric motor + battery is far less complicated than a liquid hydrogen tank, hydrogen fuel cell of which requires many energy efficiency robbing steps to get pure hydrogen

Its like they said "hey, this defeats conventional wisdom but we don't want to admit the competition is 10 steps ahead here".

Just WHERE do you fill this thing up at?

Now don't get me wrong, a nice feat, but who is going to buy it?

hydrogen fueled transportation system requires trillions of dollars to develop a system that generates enough hydrogen for demand, hydrogen plants, hydrogen transport, hydrogen fuel stations would have to be built and all of this aint cheap nor is it efficient in the total amount of energy you get from the beginning to the end.

With an electric vehicle transportation system everything is already there, the power generation, transmission and distribution is existing. Every house has a 120V socket. You dont have to do anything to change to an electric vehicle transporation system.

Sadly, I dont pass SULEV levels. Too many beans in my diet...

burning hydrogen for fuel is dumber than burning coal for fuel.

using hydrogen to produce electricity for the electric motor on the other hand...

But it reduces emission on the road tho.

I am sorry but I really don't see the point of these big luxo sedans trying to be green. Hydrogen 7, Ls600hl, etc. If you want to be green, drive a Prius.

I guess the S bluetech Hybrid is the only one that makes a little sense to me.

Fuel cells are technically hybrids. The funny thing is, most people are like "forget hybrids, they're a fad, go hydrogen!" and I'm like.. a hydrogen hybrid will still beat a straight H2 ICE in terms of FE haha. But even then, hydrogen is still expensive to produce.
