Re: Hydrogen fuel cells
"Hydrogen as a fuel is very poor when you consider the energy it takes to make it."
The energy required to make it, i.e. separate it from the oxygen in water, is the energy that's stored in it as a fuel to be recombined with oxygen so this aspect doesn't really matter. What matters is the overall efficiency with which you can go through the entire cycle.
But the issues raised in the articles are valid. It's difficult and potentially dangerous stuff to store and distribute and the overall environmental friendliness of it depends on that of the energy source.
