You didn't understand what I said. I'm not arguing about a pipeline. I'm arguing about all the little hydrogen carrying piping in the solar field. This is needed to bring together all that hydrogen being generated at the hydrogen-generating solar collectors, before it even gets to a pipeline.

Simpler just to avoid all that and generate the hydrogen at large separate electrolyzers at the side of the utility-scale solar field (say), and then inject into the pipeline.

Should be noted that that will work too. In fact that is the plan for most facilities. However, you will still need a separate electrolysis facility. With this you just pipe hydrogen into bigger pipes. It could be cheaper to implement it this way.
