Indeed… it could even be damaging, overall.
I see anything promoting the “Hydrogen Economy” as potentially problematic, mostly because the number one source of hydrogen right now is still fossil fuels. This technology is great in the context of storing energy from non-fossil origins, but it may remove the a barrier to widespread adoption of hydrogen fuel cell vehicles, the sheer cost of the platinum catalyst. While an improved electricity / hydrogen / electricity cycle might actually make hydrogen vehicles more practical (currently, they look a bit sick next to battery electric vehicles), it also opens the door to fossil-sourced hydrogen, which I don’t view as being progress.
