This is completely wrong. Energy isn't the problem. A small corner(100mix100mi) of the Nevada desert, or Spain can power the entire United States/Europe. The problem is storage and transport. Hydrogen solves that. People are so obssessed about efficiency. They're completely missing the point. You don't need to be that efficent when your source of electricity of effectively unlimited.

Isn't hydrogen pretty hard to store and transport? It's pretty corrosive and escapes through seals readily, and needs to be compressed.

  You don't have to store and transport it in pure form as gas. You could use e.g. some carrier medium (or whatever is the right English term).

    You mean a liquid hydrogen carrier pathway like liquid ammonia. That seems possible, but requires extra plants and equipment, and obviously you still have to store H2 if you want to burn it in an engine in a vehicle.

    Ammonia, the most likely carrier you're talking about has its own set of issues. It burns rather cool so will require new engine designs to overcome this. Also the engine must run efficiently or will produce nitrous oxide gases, hence smog. Lastly, and one of the bigger risk for end users is ammonia is a highly aggressive irritant. While gasoline/diesel can be bothersome in low concentrations, ammonia will send you running and choking. I personally think it will lead to consumers being more afraid of it and lead to adoption issues.

  There are attempts being made to store Hydrogen as 'green ammonia' which hopes to totally eliminate those issues: https://www.abc.net.au/news/2021-10-11/queensland-hydrogen-twiggy-forrest-ammonia-feasiblity/100528732 https://www.abc.net.au/news/2021-10-11/queensland-hydrogen-t...
