As to the most effective Hydrogen carrier I wouldn't know what to say. I  am just looking into alternatives and the discussions can become very  complex.
For me, the layman, lets keep it simple. Looking TV documentaries and  Top Gear I understand that regular Hydrogen production can be done using  solar energy.
This is mostly done by a regular temperature which isn't that efficient.  100% Solar energy creates 80% Hydrogen energy. However, recent  discovery shows that when created at a high temperature (was it 1500  Celcius?) the process becomes more efficient. 
100% Solar energy creates  140% Hydrogen energy.Sorry but this can't happen in laymans or any terms, I would explain but it has been discussed in many other threads so if your interested in the whys and hows then do a bit of a search  
I don't think that this is free energy yet, it is not breaking any  natural law. It also takes energy to build/produce the power station and  the system. How much energy goes into making the Solar Panels, the  wiring, the concrete base, the containers, and all the parts. Probably  more than the 40% left over. And then we still want to drive on this  energy.
Thus it is not yet the Holy Grail of free energy.
I agree, there is no free energy, thats just a buzz word as you always need some sort of infrastructure to harness any sort of energy.
However, as they like to repeat in Top Gear. This is one of the best  alternatives out there. Once petrol stations start adding Hydrogen  filling stations to the line the infrastructure would be there for  people to continue using cars and transport as they are doing now.
It is probably one of the few ways to convince everyone to change.  Unfortunately people don't like to change and give up their luxuries.  Hydrogen allows you to tank and drive. 
Solar means recharging overnight Only problem with that is that solar relies on the sun and the sun aint out at night  ...Maybe you mean electric in general
...Maybe you mean electric in general and thus a limited range. And people can't wait that long for a  refill/recharge.
In addition, I live in a small appartment in the city. No way my land  lord will allow me to put a Hydrogen fueling station in the drive way.  If there was the space for it, which there isn't.
I would recomend Honda and Toyota (and the others with Hydrogen  prototypes) to push for it. Goverments, markets, and people will follow.
And governments should take an example on New Zealand and the  Scandinavian countries. Get more public transport, and get that public  transport to run on Greener energy.
In many areas around Australia you see bus's running on natural gas, ethanol and Bio Diesel so it's cathing on
Alas, as of today no scientist found the holy grail and free energy.  But, we can certainly make use of the Greener energies.
I got a Series 1 from 1958 in all original state. And I would change its  engine in no time if this would mean Greener driving.
In my opinion, the fact you are driving a car from 1958 means that you do not contribute to poluting the planet with cars made from plastics and other polutants and not contributing to the energy used to produce newer cars so in that way, us Landrover owners who keep rebuilding our cars are much greener than the average Prius owner by far regardless of what comes out of the tail pipe. 
This is what Land Rover should stand for... Green Driving.... That is  why I love Land Rovers,... it gets me into the nature, into the green.
Specificly to the thread... Will such a station use the high temperature method? I think that would be unlikely... Dangerous system if so...
Are there any plans in Australia to implement Hydrogen petrol stations  etc?
Nice to have a new Honda on Hydrogen. But what about me putting a  Hydrogen engine in my old Land Rover? Possible?
