"Yes, I know, hydrogen is difficult to get"
It's not difficult to get, but it is difficult to store and distribute when compared with hydrocarbon fuels; so being able to make hydrogen using solar power and then make electricity from hydrogen is not a complete solution.
And scaling these technologies is usually the problem; a few years ago bio-fuels were all the rage, until it was pointed out that there isn't enough farmland to grow enough to replace even a fraction of the fossil fuels that we use.
Economists love to count chickens before they're hatched, so don't go encouraging them.
