[AF] H and O as fuel

[Harold Hallikainen]

Use of hydrogen and oxygen as a fuel, of course, does not create any
energy, it is just a storage method. In this case, it appears to be
conversion of electrical to chemical to mechanical (running a car). The
critical issues on energy storage are energy efficiency (energy out /
energy in), volumetric efficiency (W / liter), mass efficiency (W / gram),
and safety (will it blow up). In fixed applications (or other less weight
and volume applications such as marine and railroad), the energy
efficiency is the most important consideration. In automotive
applications, all of these considerations are important. So, how does
hydrogen and oxygen compare with, say, the lead-acid battery, the
lithium-ion battery, or gasoline on these factors?
