Question

Name three advantages for using hydrogen as a fuel in cars.?

Answer 1

The only waste product is water vs. carbon. Second it doesnt burn anything. Third hydrogen is abundant and is a never ending supply.  But the only problem is the cars that use hydrogen are costly and very few places to fill them up.

Answer 2

1 - Only "on site" emissions - water

2 - car is quiet, and electric motor and fuel are lighter than a gas engine or current electric vehicle batteries

3 - Doesn't require dependence on fossil fuels

Now the problems:

1 - Hydrogen doesn't appear anywhere in nature by itself

2 - Currently does use fossil fuels to make hydrogen

3 - Fueling Infrastructure

4 - Storing enough hydrogen gas under pressure to have decent range (bigger hydrogen tank under more pressure = bigger hydrogen bomb)

5 - Cost, cost, cost

Right now it is not practical.  We'll see in 10-20 years.  Things might change.

Answer 3

1) Hydrogen is a renewable energy source.

2) Zero emissions

3) Ending our dependancy on foreign oil

Answer 4

i am interested but don't understand

Answer 5

As stated by Milez, it depends on where you're getting the hydrogen.  The only efficient method we currently have of getting hydrogen is from natural gas, and that method creates as much carbon dioxide emissions as burning gasoline.  Thus at the moment there is no advantage to using hydrogen in cars.

There can be advantages if we can get the hydrogen from a clean source, such as aluminum alloys.  Really the whole point and the only advantage that matters is that the only emission would be water - no carbon dioxide.  At the moment there are serious disadvantages, like the amount of money being diverted to hydrogen technologies which are at least 20 years (probably more like 40) away from widespread commercial use.  The money should be going to other technologies like hybrids, electric, and biodiesel with a fraction going to hydrogen as a partial long-term solution.

Answer 6

1.No polution

2.can find fuel anywhere

3.Cheap

Answer 7

There is some info here.

Answer 8

There are no advantages. At the present time, the amount of energy required as input would exceed the energy output. It is a net energy loser, and thus it has no advantages.
