If a majority of our automobiles were replaced with vehicles which operate on hydrogen powered fuel cells, how could massive amounts of hydrogen be stored safely for refueling? How safe are these cars when the fuel tank ruptures due to collision compared to current gasoline/diesel ones currently in use? How many miles will the vehicles be able to go before refueling?

Global warming: Does it take MORE energy to create hydrogen than PROVIDED in hydrogen fuel cell cars?
The round trip is a net loss isn't it? We use electricity to convert H2O into H and O.
Then in a hydrogen fuel cell car, we RE-convert the H and O back into H2O again.
So it is a round trip.
But since every mechanical device LOSES energy through friction and heat and waste, the round trip from H2O to H & O and back to H2O LOSES energy.
Isn't this right? So how will a hydrogen economy run the country or replace oil-burning cars?
How can cars that run on gasoline be converted to run on hydrogen fuel cell?
I previously posted a question on can cars be converted to fun from gasoline to hydrogen fuel cell. many of you said yes but i still dont know how it can be converted and exactly how much will it cost? thanks a bunch!
Planning on buying a car, what has the best gas mileage in U.S?
When are the plug in hybrids arriving to the market? I heard something about Fuel and Hydrogen cell cars, when are these cars supposed to come out? I want something around 100 mpg.
When will someone make a decent EV?
I drive only 5-20 miles a day, but part of that is on the highway at 70 mph. I need an electric car that can do decent speed, but I don't have 0,000 for a Tesla.
When are the major manufacturers going to sever this incestuous relationship they have with the oil companies and start selling what folks like me need?
I'll probably always have a fueled vehicle – nitrogen gas or hydrogen or fuel cell or biodiesel or even (gasp) gasoline – for long distance trips and hauling the family.
But for my daily drives to work and back, I don't need capacity, or even much range, just reliability and speed. And I don't seem to be alone – there are a lot of drivers on the road with me who are alone in their cars.
Does anyone have an idea when we might see a real "plug-in" car?

Does no one read the question? "Someday" is no answer, and neither is "no demand" and neither is "try a search." If anyone has an idea, please let me know, but if you haven't a clue, keep your comments, please.
When will hydrogen cars be available to the public? They are already being used as prototype vehicles. I was?
told by student that Hummer already has one, and that the military has been experimenting with them because of how quiet they are. I showed my class a "Cars of the Future" film about hydrogen powered vehicles. They seem to have endless possiblities, and they are safe. Solid hydrogen fuel in the form of metal alloy can be dispensed and stored. Iceland already has a Shell station that not only dispenses hydrogen fuel but makes it right on the site, so that no delivery trucks are used. The only emision from the engine is a few drops of water. The car that was featured had a chasis with the engine and fuel cells under the floorboard. All that was needed was a body to be lifted onto it.
What are hydrogen or hydrogen cell (I don’t even know the term=/!!) fueled cars? What’s the difference between
…that and oil fueled cars?
How far are we from Fuel Cell technology ?
Will fuel cell powered cars using hydrogen fuel be available in a couple of decades…I am wondering. It seems plausible to me reading the statements made by the charimen of many hydrogen fuel projects.
Is hydrogen fuel-injection more potent than hydrogen fuel cell?
What is the energy difference (energy output) in hydrogen burning in a fuel injection (combustion) engine and hydrogen used in producing electricity in hydrogen fuel cells? Gasoline power is stronger.
BMW has made a hydrogen fuel-injection based car, meaning this is not a hydrogen fuel cell, but the same engine used for burning gasoline, but now it burns hydrogen instead. The car is found here.

What I am wondering is, that if hydrogen gas when burned is the same potent as gasoline, then shouldn't a fuel injection engine be more powerful than a fuel-cell electric engine? My particular interest if the two are different energies (battery cell vs. hydrogen combustion). If hydrogen combustion produces more horsepowers, then that extra energy could theoretically make up for the 30-40 percent energy loss in making hydrogen.

2010 Toyota Prius. As the go-to symbol of environmental consciousness, the Toyota Prius enters its third generation with improved under 10-second zero-to-60 acceleration thanks to a more powerful version of its hybrid synergy drive gas-electric powertrain. At the same time, the 2010 Toyota Prius sees improved fuel economy with an estimated average of 50 mpg thanks in part to a low-drag super-slick new shape.
