I read some interesting stuff about how Japan plan to create green hydrogen and convert it into ammonia to send through their existing gas infrastructure.
That does sound interesting, but its no hydrogen as a fuel source (like the article), its used in your description as a single link in a chain. So they’re creating hydrogen from a process (likely electrolysis) using some other energy source, then nearly immediately converting that hydrogen into ammonia for better storage and transport. That would be a good use of hydrogen, as an intermediate step and not a beginning and end step.
