Re:Hydrogen production

You're absolutely correct that the infrastructure for hydrogen fuel is nearly non-existent. Today, most hydrogen fuel is derived from natural gas using a steam reforming process. Automakers know the infrastructure is weak, of course. They also know the costs will be high and they have no idea how reliable these cars will be. Still, they're dipping a toe in the water as an engineering exercise. They want to know how much long-term potential is there, and how many years it will be before these cars can be a viable option.

Elizebeth you are absolutely correct this Mercedes Benz is an extremely stylish one it is looking like very unique and delicate vehicle i havent seen such a goodlooking car even in hybrid technology .

The concept of using hydrogen gas as a feul is a good one,  with the same amount of hydrogen gas the car will cover twice as much distance as by petrol. Secondly it is enviornmental healthy because it only emmits water vapour when burned not carbon dioxide .

However every new technologyhas pros and cons one disadvantage of using hydrogen gas as feul is that it is expensive .Secondly it is difficult to store it because its a gas not liquid .

Looks like a big step forward until you hit a 2013 pothole!

Hydrogen is not a readily availabe fuel like fossil fuel. How is this hydrogen fuel produced? Do hydrogen fuel face the problem of storage and transportation?

Even though hydrogen is available plentiful, laws of thermodynamics restrict its usage. Laws prove that hydrogen will always be less efficient than any other alternatives. The phase changes required to produce and then burn hydrogen will always waste more energy than simply using electricity directly.

H2 cars

H2 cars coming?  I need to go out and invest in a H2 gas station before all the franchises are gone!

I think we have a problem here, Houston.  First, H2 is a great gas.  I appreciate all its many fine qualities, inluding space rockets, welding, breathing, etc.  Great gas!

But, although it is plentiful and God makes more all the time, it is a tough nut to crack in using it on a large scale.  H2 and He are the only gases that escape gravity into the ionosphere and are gone, gone, gone!  So, bottles to hold it are special.

Then there is the explosive storage problem.

And it eats metal problem.

But other than that, bring it on! 

Having said all this, I do believe the fuel cell is viable and I look forward to seeing them everywhere.  I don't know if it is an efficient method of converting hyrofuels, but neither is the ICE! 

We need breakthroughs!

I'm with you, Rob, the Mercedes-Benz stands out. It seems like hydrogen car makers are already thinking about more stylish designs than the current EV/hybrid makers. Or maybe it's just Mercedes, an icon of great car style, that's thinking retro to get ahead.

Nice slide show, Chuck. I particularly like what the students did with the Mercedes-Benz. Going back to 1896 looks like a big step forward.
