Hydrogen fuel costs nothing,why not use instead of petrol like senator Schwarzenegger?

Question

Hydrodgen fuel is also 20% more efficient, the cost to convert for use in any car about £ 350 no more fuel bills, no more need for oil in quantity no pollution produced to affect global warming, kill three birds with one stone

Answer 1

Sorry, that's real nonsense!!!

Hydrogen fuel is no independent energy but only a way to store energy - nothing else than a battery!

The huge problem is how and with what kind of energy to produce (extract) pure hydrogen at all!

Answer 2

Didn't Schwarzenegger promote the hummer?

Hydrogen is expensive and hard to find. It requires a lot of electricity to produce the quantities required to drive a car. It is also difficult to store and transport.

To convert a car from petrol (gas) or diesel to hydrogen requires replacing the IC engine with an electric motor and a set of batteries, as well as the oxidisation equipment. Also, the car would not be nearly as efficient as a bespoke fuel cell car.

Sorry to burst your bubble, but the planet you're living on sounds nice.

Answer 3

You must be thinking about conversion to alcohol. Conversion to hydrogen requires replacing the engine. Internal combustion isn't the most efficient way to use hydrogen as a fuel. The hydrogen cell uses the ionic forces of the gas to create electricity directly. These are very expensive, but the price will come down eventually.

Answer 4

------------
Alas, hydrogen cannot be found free. Perhaps you are referring to the extraction of hydrogen from water? This is not free either, since the process requires electricity. In fact, due to the inherent inefficiencies of this process, the same electricity used to extract hydrogen, if used to charge an electric vehicle, would result in more miles driven by the EV than the FCV could get.

In fact, a hydrogen fuel cell car IS an electric car, with batteries (the batteries are required for acceleration currents), and a fuel cell added on top. So a fuel-cell vehicle will always be more expensive, and less efficient than a pure electric vehicle.
*
So why are we being sold hydrogen cars, instead of just electric cars? The petroleum industry likes the idea, because they can run the hydrogen infrastructure.

Take a look at this new electric car, and tell me why we need to add a hydrogen tank to it:

The Phoenix electric pickup truck - using new, advanced Altairnano batteries (based on research from MIT) - can:

-Travel up to 250 miles per charge
-Carry 5 passengers plus cargo at 95mph.
-Charges batteries in as little as TEN MINUTES.
-Has batteries that last 250,000 miles (never need replacement.)

Answer 5

No more fuel bills? Since when do they sell hydrogen for free? And where do you buy a hydrogen car from? And where exactly do you fill up? And if you find a hydrogen station, where do they get it from? From hydrocarbons...

Hydrogen is the energy of the carrier of the future,... and may remain so for a while. If you want to cut down energy use, pollution, global warming, and your transport bills, think about ways to travel less, walk , cycle or use public transport as much as possible, etc...

Answer 6

It doesn't cost nothing. Collecting or creating hydrogen fuel costs money. It's also a very very light fuel. Actually it's the least dense fuel you could possibly use so you would need ALOT of it if you were going to burn it to run an engine. You could never carry enough of it with you do go more than a short distance.
The real benefit of hydrogen would be using it in a fuel cell to power an electric motor.

Gasoline is C6-H18 That means that there are 18 hydrogen atoms per molecule of gasoline. The ratio of ogygen to fuel when you burn gasoline is 14:1 If you were to burn hydrogen instead you would need 1:2 in terms of oxygen to hydrogen. That means you need to burn 28 times more hydrogen than gasoline to make the same amount of energy. Imagine a gas tank 28 times bigger than the one in your car right now. Or imagine being able to go 28 times less far with an equal amount of fuel.

Answer 7

Are you referring to the fuel cells that produce electricity, but cost somewhere in the neighborhood of $3,000 to produce, and are quite dangerous to use due to the byproducts?

Or using hydrogen itself as a fuel in an internal combustion engine?

The US Department of Energy estimates that by 2040 cars and light trucks powered by fuel cells will require about 150 megatons per year of hydrogen.3 The US currently produces about 9 megatons per year, almost all of it by reforming natural gas.

So all you are doing is shifting from one source of hydrocarbon to another. How do you figure it costs nothing?

Answer 8

It costs money to make hydrogen. It is not found in it's free state in nature on Earth. It has to be broken out of water or some other hydrogen bearing chemical.

Hydrogen is not more efficient than petrol, partly due to it's low density and partly do to the containment requirements.

Also, Schwarzenegger is a governor, not a senator.

Answer 9

wherever did you get the idea that hydrogen cost nothing ? the term "free hydrogen" means something altogether different , this fuel is a real pain to store and transport and production methods are not fully sorted out yet , don't worry , we have more oil in Canada than uncle sam can burn in a long time.

Answer 10

Hydrogen fuel does not cost nothing. I also bet a it takes alot more money to convert any car to a hydrogen vehicle.
