Bmw cutting back on its hydrogen car development

Hydrogen is one of the best but the security requirements are to high and is very dangerous...and expensive.

...and therefore not the best.

Hydrogen is one of the worst investments of capital, and here is bmw admitting to that. Face it, there are no longer any big hydrodgen projects on the horizon anymore. People are slowly starting to realize all of its drawbacks.
Drawbacks including
1)The most efficient fuel cells to date can get 80% of the energy out of hydrogen, but they need to be operated at 800 Celsius before they can acheive those efficiencies. Basically you would need to keep your car plugged in, always running or take half an hour to get the vehicle running if you want to run efficiently, if you don't run a fuel cell at those temperatures you might get 40% efficiency
2)Unlike gasoline and diesel hydrogen requires vast amounts of energy to be created, and at present most of the worlds hydrogen is produced by separating hydrogen from fossil fuels in a process called cracking... this process isn't 100% efficient either and in the end uses more fuel then the hydrogen it produces.
3)Storage remains an issue, the only way to store the amount of hydrogen required for an automobile is by super cooling it. Tanks that can keep hydrogen liquid require a constant drain of energy to keep the temperature down, and storing the hydrogen at -250 below Celsius and then heating it up to 800 Celsius to achieve "maximum" efficiency is a tremendous waste of energy in itself.
4) Most hydrogen cars to date still you internal combustion engines resulting in even poorer performance (about 10% efficiency)

Some of the issues with "hydrogen as auto fuel" concept are (not in any order):

(1) Though hydrogen is virtually everywhere, getting it into a form that can be consumed by cars takes a lot of energy. That's a *LOT* of energy. So much so, that we expend more energy in making hydrogen "usable," than the amount of energy it releases to propel a car. Read "low total efficiency."

(2) Though hydrogen burns very cleanly, so far, the best scientific minds on the planet have no idea of how to "cheaply and cleanly" transform H2 molecules into a form that is usable as car fuel. In fact, the best minds on the planet say they can't imagine that day coming. Read "there is nothing even remotely conceivable to make this idea feasible."

(3) There is no infrastructure in place for "hydrogen as car fuel". No mass manufacturing sites, no mass storage facilities, and no fuel transportation infrastructure. Should by some miracle, #1 and #2 be resolved today, then this issue means we're still between 1 and 2 decades away from realizing the dream of hydrogen replacing gasoline. Read "why is BMW making vehicles that need a miracle today in order to make them useful around 2029?"

Aside from these few niggly things, sure, hydrogen as car fuel shows some promise. I guess BMW finally got a clue, and so, they replaced the "We're so green, we make hydrogen cars" PR hype with the "we're so green, we're gonna make electric cars" PR hype.

Same hype. New day.

LOL we wrote our lists at the same time

I suggest they team up with MAZDA and Honda(?).

Eletric is the future.

In america no diesel is.

Diesel is 19th and 20th century- the PAST, not the Future. Electric will take over soon, and the only place you will find diesel will be where it belongs- a Museum
