Line 1:
Line 1: − The '''hydrogen [[economy]]''' is a term for a economic system in which [[hydrogen]] is used to store [[energy]]. Burning compressed [[hydrogen]], a chemical compound (H<sub>2</sub>) could be used in [[fuel cell]]s to produce energy without [[carbon dioxide]] emissions. Instead, [[water]] would be produced. + − − Hydrogen, which is the most abundant of all elements, is found in stars and is a volatile gas on [[earth]]. − − It is widely believed that the hydrogen economy will replace the current [[fossil fuel]] economy where internal combustion engines burn gasoline. However, only a few companies have begun selling hydrogen [[automobiles|vehicles]] and there are a limited number of fueling stations, mainly in the California and Washington DC areas. Hydrogen itself is not a fuel source, but is a carrier of energy. That is, the energy to create the hydrogen must come from somewhere else. − − Despite this, a new hydrogen economy would have the advantages of reducing the economic and security risks of importing oil, reducing the risks of environmental pollution (like oil spills, smog and global warming). − − [[Category:ecology]]
