Why don’t we have many Hydrogen powered cars?
(this is what i think)They say that the Hydrogen tanks would explode during a crash. That is a lie. Hydrogen tanks aren’t any more dangerous than a gas tank. Uncle Sam doesn’t want hydrogen powered cars because their little oil buddies would loose billions in $’s. If we really have a problem with “supply and demand” the government better get their @**es moving to make sure the Hydrogen tanks won’t “explode”.

Many reasons, such as lack of infrastructure, cost, inefficiency, etc. See the link below for details.
Maria asks…
Do you think hydrogen cars will ever be popular?
They seem like the answer to our high gas prices. I don’t understand why they are not being marketed much. Even electric cars get more attention and I think they are an inferior solution.
admin answers:
As long as someone can invent way to make cheap fuel cell. They can make hydrogen cars no problem, BMW, Honda and others have hydrogen cars out there most are demos and some you can buy or participate as test programs. But there isn’t affordable way to go hydrogen yet. Fuel cells are incredibly technical and expense. Hydrogen cars are electric cars but it gets electric from fuel cell technology instead of getting power off grid. Right now getting power off grid is quick and cheaper/easier way.
John asks…
If we start using Hydrogen cars, and get hydrogen from water, won’t we run out of water someday?
Basically, I figure you get 2 hydrogen atoms and 1 oxygen from water. Now if we use that hydrogen to burn and make energy then, won’t we be using up all the hydrogen to reform with oxygen that will remake the water eventually just leaving us with a dried up planet full of oxygen.
admin answers:
The process is physical, not chemical, and therefore it isn’t permanent. The water will return. Besides, hydrogen is literally the most abundant resource in the entire universe.
Donna asks…
why should america make a switch to hydrogen powered cars?
why should america make a switch to hydrogen powered cars?
admin answers:
To not use cars that require gasoline (oil). We don’t wanna depend on oil too much since we’re going to run out in the next 20-40 years.

How to Mass Produce Hydrogen for hydrogen-powered cars?
This is a little question I was thinking about for this chemistry project I’m doing for school. I know that it takes energy to create Hydrogen and remove hydrogen from water or other substances. So i wanted to know what are the most energy, time, and money efficient ways to mass produce hydrogen and transport around the world if hydrogen powered cars began popular.
Any ideas?
became** not began
How about some in depth ideas on the subject?
admin answers:
It just takes electricity to make hydrogen.
There isn’t anything magic about it.
I was interested to read:
<>
one might note that you don’t mine pure iron.
You mine iron oxide, and use lots of energy to separate it from the oxygen.
If your aim it to make hydrogen, you’d do well to skip that step, and just make the hydrogen.
As for transporting it, you have a couple of options.
Compress, and really cool it.
Use some substance that “sops it up like a sponge”.
Thus far, it seems to me that neither option would work very well for a car.
In that light, your question, “if hydrogen powered cars began popular” is not realistic.
They can’t, unless the storage problem is first solved.
Chris asks…
What are the negatives of cars using hydrogen instead of LPG or petrol?
If indeed we are going to run out of oil supply and we still need cars to go from A to B, we need an alternative and we are told there will not be any air pollution from cars running on hydrogen!
admin answers:
Hydrogen can only be produced by using other energy sources. These energy sources are inherently polluting and because it is inefficient to convert these to hydrogen, making hydrogen is more polluting than simply burning the fuel. Also it has less energy per unit volume than other liquid fuels. Oil companies will have to replace their liquid handling systems with gas handling systems, cars will have to drive around with pressurised containers full of flammable gas. Apart from that…
