“...the existing [natural gas] pipeline network can be used to transport hydrogen from the west to the eastern coastal cities” ---Hu Guoping, a researcher with the Ganjiang Innovation Academy at the Chinese Academy of Sciences

Being an academic, it is likely that Mr. Hu has never heard of hydrogen embrittlement. You really don't want your hydrogen pipeline getting brittle and going KA-BLOOEY!

Perhaps they can create ginormous pit mines everywhere to mine enough materials to make enough solar cells to cover thousands of square miles to super inefficiently create hydrogen by electrolysis. Sounds Wiley Coyote level of genius

Hydrogen pipelines

I understand there are several engineering problems to be solved, and there has to date been no successful demonstration project to harvest “green hydrogen” at any kind of scale. If they can do it, then great. Let’s see it in action.

Gaseous hydrogen can be transported through pipelines much the way natural gas is today. Approximately 1,600 miles of hydrogen pipelines are currently operating in the United States.

Another problem that I can think of is that hydrogen molecules are so tiny that they can escape from nearly anything.
