Not necessarily....
The single biggest issue with hydrogen is that in order to produce it you need to use another energy source in which to do it. So ironically the cheapest way to do so is by using natural gas... which then makes producing it a matter of economics: Does it makes sense to use energy to make energy? In essence regardless of the source it will always require more energy to make hydrogen: thus it is an inefficient fuel source.

single biggest issue with hydrogen is that in order to produce it you need to use another energy source in which to do it.
I attended a DOE/NREL presentation on Hydrogen this morning.
They were discussing the roll out of H2 stations in California.
One requirement is that a certain number of them must generate the H2 using completely renewable resources.
In fact, the next two stations being built will use 100% renewable energy.
Also, there are new catalytic methods (non electrolysis) that directly produce the h2 from water mimicking the process of photosynthesis.
We're off to the races!
"All of these filling stations will be fitted with an electrolyser, allowing them to produce the hydrogen on site. This additional technology will produce totally decarbonised hydrogen (with no CO(2) emissions) using clean electricity from renewable energy sources as part of the plan announced by the Danish government in 2012, whose target is to have 100 % of renewable energies by 2050."
