Unfortunately, producing the hydrogen is not that efficient. No free
lunch,
once again.


It is fairly efficient cracking a hydrocarbon to produce H2 - improving
the
efficiency of the use of fossil fuel by about 100 % also has utility.

Messing around with pure hydrogen is silly and represents the typical
eco-loon thinking I.M.O - there is a vast infrastructure for handling
hydrogen when wrapped in a liquid but there is none for pure H2.

If by "wrapped in a liquid" you mean carried in methanol, the problem with
that is that fuel-cell conversion efficiency drops from around 80% to 30 -
40% when you do that.

No free lunch.
