A couple of issues which are not well developed in the linked articles:

• While hydrogen can be produced by splitting water electrolytically, “… in practice, the majority of hydrogen (∼95%) is produced from fossil fuels by steam reforming or partial oxidation of methane & coal gasification …”* I.e. it is not “green”.
• “The large amount of energy required to isolate hydrogen from natural compounds (water, natural gas, biomass), package the light gas by compression or liquefaction, transfer the energy carrier to the user, plus the energy lost when it is converted to useful electricity with fuel cells, leaves around 25% for practical use.” – Dr. Ulf Bossel**

One good piece of news though: there is nothing fundamental to hydrogen fuel cell technology that requires FCVs to be as ugly as the one pictured above.
