Perhaps you missed the real reason:

Shell closed three of its five hydrogen stations last fall, calling the closures “temporary” but declining to say when they might reopen. Hydrogen refueling stations tend to suffer from serious reliability issues due to the nature of liquid hydrogen, which is notoriously difficult to handle. Iwatani, a Japanese gas company that is one of the two largest names in American hydrogen filling stations, is currently suing Nel, the Norwegian company that provided the core technology for its stations, claiming it was bamboozled by that company.
