What problems prevent the widespread use of hydrogen fuel cells?
The two main problems facing the hydrogen economy are the production and storage of hydrogen. Hydrogen fuel can be made in several different ways, but all result in pollution, canceling out the benefits of using hydrogen instead of petroleum. Electrolysis, or extracting hydrogen by splitting water molecules with electricity, is the most promising, as "it is unlikely that hydrogen in the quantities needed could be achieved in a sustainable way without ...
