Well you can create hydrogen via solar and it sounds like a good idea at first but there are several reasons why it is losing a bit of its steam.

Probably the first and foremost reason has to deal with politics; utilizing hydrogen would require an entirely new infrastructure for transporting it across large expanses. Pipelines, trucks, etc. Quite frankly I don't have faith in any of our politicians here in the U.S. to allow for a non-complicated process that is devoid of any bureaucratic nonsense. The simplest things in this world get tied up behind miles of red tape and bickering.

Alongside the political factor, an entirely new infrastructure would be very resource demanding and time consuming, not to mention we'd have to engineer it to begin with. I imagine one could recycle some of the materials from our current gas pipelines but we'd still be relying on most of them if we were to develop hydrogen within the next ten years.

Transportation itself creates yet another huge problem because of the way hydrogen is as an atom. It is incredibly small and would seep out through any of current pipelines. It would be a real pain in the ass to create a system that retains most/all of the hydrogen through long distance transporation. I've heard several scientists say that is one of the bigger turnoffs for hydrogen; we haven't found an effective way for long distance storage and transportation.

I'd love to see hydrogen be developed. I absolutely love to think of the idea of hydrogen powered cars and I hope that we put investment and research into it. But as much as I am rooting for hydrogen (it's like my main choice for a political candidate) to come out strong, I don't think it will ever be fully developed or utilized. At best, I see it becoming a niche fuel source in certain parts of the world. I know Germany has some fueling stations, and that is how I imagine what the future of hydrogen will be.
