People said the same thing when BEVs were coming out. Personally, I think the main hidden benefits of hydrogen isn’t fast refueling and range, but rather weight and ease of storage.
Hydrogen may be the solution to enable mass adoption of variable renewable power plants, allowing relatively cheap energy storage between seasons. Doesn’t matter if you only get 50% efficiency if you can produce it when electricity is dirt cheap and then store it nigh indefinitely.
As for the weight - the real money in vehicles is in the commercial sector, where weight is precious. Any weight lugging around batteries is dead weight - and hydrogen means less weight than lithium batteries.
