There is often the question why not build solar powerplants out in the desert ? Well, solar panels require surface area and they require sunlight with both things being available in the desert. I suppose the answer is that while alternating-current can be transmitted long distances, the distances are probably held to about 200 miles.
But Los Angeles and surrounding metros are near to the desert and sure enough there is a 354 MW solar powerplant in the Mojave Desert. Now these large solar powerplants don't use solar panels to produce electricity but use solar mirrors to heat water, make steam, turn turbines, and then produce electricity.
But here's an idea or question:
Why not use solar mirror powerplants in the desert to make hydrogen from pumped water and then send the hydrogen further distances in pipelines than electricity could be transmitted on power lines ?
Well, I'll answer my own question and say that likely there is more power to be had from the steam than from the hydrogen production.
But don't forget, there are solar powerplants in the desert.
