Les, we could put the hydrogen into Zeppelins and fly it to where it's needed! Apparently Zeppelins were not as intrinsically flammable as was once thought. I believe that the fabric which covered the outside of the Hindenburg etc. was actually 'doped' with a mixture of iron oxide and aluminium powder (thermite!!) - it only took an electrostatic spark to turn the whole thing into a giant bomb (no German chemists were prosecuted for gross negligence - but should have been!).
The other aspect of this plan (assuming use of solar energy) is that we would be exporting energy from hot, poor parts of the world to cooler, richer parts of the world - so, business as usual!
