I haven't been on here in a couple years but nice to see some more discussions about hydrogen as an energy storage 'fuel' for use in cars. I'll bring another post to the front which had some interesting information. One thing in particular is that whether you burn the hydrocarbon directly or reform it to hydrogen and use that, the same ammount of water is produced. Also, to answer some questions:
A supercharged ICE running on pure hydrogen has similar power density to a normally aspirated ICE running on gasoline.
A diesel ICE is actually more suited to running on hydrogen due to its higher compression ratio.
Theoretically the only byproduct of burning hydrogen is water. In practice in an ICE you would have some carbon dioxide and monoxide, from burning engine oil, as well as some nitrous oxides. The NOx may only be present in the exaust at very rich mixtures, I am not sure. In a fuel cell generally the only byproduct is water. However, fuel cells generally need very pure (99.9%) hydrogen.
It is possible to create hydrogen relatively 'easily' using electrolysis. All you need is salt water (not necessarilly table salt) and some electric current. Be careful if you want to try this because hydrogen is flammable and electricity can be dangerous. But it can be done, outside, with table salt, water, and a 9v battery. The little bubbles you see are H2 and O2 gasses.

Yeah you are right... it is lean mixtures. And yes, the ammount of *** and NOx are very small if you run a hydrogen ICE, but they are zero in a hydrogen fuel cell. And also, a hydrogen fuel cell has the potential for a significantly higher efficiency than an ICE.
