1. Hydrogen is highly flammable. This can be very dangerous if hydrogen is used as a domestic fuel or in vehicles because it can combust instantaneously.
2. Hydrogen is a gas at room temperature. This makes the storage and transportation of hydrogen more difficult as compared to liquid fuels like petrol and liquified petroleum gas, because a gas fuel occupies a large volume (unless pressuried), cannot be poured and can be easily lost to the surrounding air by diffusion.
hydrogen is highly combustible..hence direct contact can cause an immediate fibre
Much electricity is needed to generate the Hydrogen.
It is very difficult to store because it has very low density.
It is highly flammable ( more higher than gasoline).
It is not easy to set up a hydrogen fuel generating unit.
thats it even petrol and gasoline has more advantages than this and dont just see the dis advantage parts see the advantages it has.
scarcity of hydrogen..

Why is hydrogen gas a good option for an alternative fuel to fossil fuel?
fossil fuel may be depleted soon. but hydrogen gas can me made available. also, if there are cheaper ways to split water into hydrogen and oxygen, then the better it is as water is available everywhere ----------------------------------------------------------------- Fuel cells produce hydrogen gas from fossil fuels, and renewable fuel sources. Hydrogen can also be made from other energy (electric) sources and electrolysis of water, but compressing and transporting it poses it's own problems. Despite this, the production of hydrogen as a fuel source uses more energy than can be gained from the hydrogen itself.
Why does the amount of hydrogen in a star decrease?
Because Hydrogen is the fuel of Stars, hydrogen consumed and Helium is formed.
Where does the hydrogen we use as a fuel come from?
Some industrial chemistry gives hydrogen as a by product fro example the electrolysis of brine (salt water) would give hydrogen. We can also electrolyse water to give hydrogen for fuel.
Can you feel hydrogen?
I don't think it is possible to feel hydrogen.
Is hydrogen compression possible?
We can compress the hydrogen because hydrogen gas is stored in the cylinders.
What are the disadvantages of using water as a hydrogen fuel source?
It takes more energy to separate the hydrogen than we can get at the end.
What are the advantages and the disadvantages of a hydrogen fuel cell car over a hybrid car?
Advantages are very low emissions. Disadvantage is rarity of hydrogen fuel stations.
What are advantages and disadvantages of hydrogen fuel cells?
The advantages of using hydrogen fuel cells are that they are an alternative fuel to fossil fuels, like coal, oil and gas. Also, burning or reacting hydrogen with oxygen runs electric motors and it's only emission is water vapour. The disadvantages of using hydrogen fuel cells is that hydrogen does not occur naturally on Earth and thus is not an energy source. It takes a great deal of energy to extract Hydrogen from water. Hope this helps! :)

Is it possible to get hydrogen fuel from biomass?
Yes. However, it is not yet economically practical, as it takes more energy to convert the biomass into hydrogen than we can get from using the hydrogen for fuel.
What are the advantages and disadvantages of hydrogen as an alternative fuel?
Hydrogen is plentiful therefore cheep. It is also volatile if not handled properly. Comparatively, a hydrogen explosion can be close to a nuclear explosion damage wise.
Can you use sucrose as hydrogen fuel in the car?
I suppose that is not possible; and also is not economic.
How can one get as much hydrogen as possible into a space shuttle's fuel tank?
Fill it
Is any disadvantages of fuel energizer?
yes there is no answer for disadvantages of fuel energizer
What are the disadvantages about hydrogen?
Hydrogen is very flammable and can easily explode. Look back the Hindenburg blimp that used hydrogen. Hydrogen burns very cleanly leaving just water vapor of a byproduct. Using Hydrogen as a fuel for cars sounds great except that you need to make it by splitting water into Hydrogen and Oxygen. That uses up as much energy as the burning of Hydrogen releases. In use as a fuel for cars, you can imagine the explosion when a hydrogen tank bursts and ignites.
What is the byproduct of hydrogen fuel cell?
Water is the benefit of a hydrogen fuel cell ;)
What are some disadvantages of hydrogen energy.?
Hydrogen Energy is currently more expensive than any other fuel source, there is also no existing infrastructure to accommodate a Hydrogen fuel cell. The process for extracting Hydrogen to be used also usually requires the use of burning fossil fuels, thus creating pollution. Then there is the fact Hydrogen is both hard to store and distribute.
