it is very expensive compared to other forms of energy such as electricity
It takes more energy to separate the hydrogen than we can get at the end.
hydrogen is highly explosive.
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! :)
There are no energy sources without disadvantages.
renewable energy source non-poluting very safe and in-expensive large amounts can be stored up and used later
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.
What are the advantages and disadvantages of wave energy
the energy source for hydrogen is semen ;)
Hydrogen is an element and an energy source itself.
It isn't - there are no large deposits of hydrogen anywhere. Hydrogen can be used for energy STORAGE.
Since there are no significant amounts of free hydrogen, it should be considered more of an energy storage than an energy source. In other words, it takes energy to separate water into hydrogen and oxygen; you get that energy back when the hydrogen is burned.
The products of hydrogen fusion are helium and energy.
The nuclear energy available in the hydrogen. This is a kind of potential energy. Hydrogen has a higher energy level than helium.
The disadvantages of heat are that if there is no solar energy, then there is no heat.
Hydrogen helps humans conserve energy with combustion in our bodies. Without hydrogen there is no combustion, so there is no energy.
This is probably assuming the hydrogen production is driven by wind energy which is renewable.
hydrogen is a renewable energy source
No, energy is produced by the opposite reaction, hydrogen to helium
Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.Stars get their energy from nuclear fusion - mainly, hydrogen to helium.
No similarities: - uranium: energy released by fission - hydrogen: energy released by oxidation
requires high pressure
