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.
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.
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! :)

What are some disadvantages or advantages in chemical energy?
renewable energy source non-poluting very safe and in-expensive large amounts can be stored up and used later
the answer is yes because if the world ends then hydrogen is an energy source and in some places people are using it already
some chemical energy causes pollution
There are no energy sources without disadvantages.
he failed to explain line spectrum of elements except hydrogen.
Initial costneed to store energy for times of no Sun
There are multiple applications and pathways towards hydrogen based energy production. These include hydrogen fuel cell reactors to for?ænon-fossil fuel based vehicles. The ultimate steps to hydrogen energy production as fusion reactors.
they aren't as convienent as nonrenewable resources
