There is more to it that just the technology though. Public adoption is a significant factor, and for the most part, the Hydrogen still comes from natural gas, so is still a fossil fuel. On that basis, while *arguably* a superior technology, it does not adequately meet the goals of the buyers.
I disagree that it hinder progress. I think EVs have brought widespread interest and understanding, whereas Hydrogen fuelling is often still seen as Doc from back to the future stuff.
I personally think hybrids are a slightly-better-than-nothing-half-attempt. Charging infrastructure requires very little investment compared to Hydrogen (the power lines are all already there, just need the stations adding).
EVs are FAR better suited to a significant amount of trips by a significant number of people - but not all. If you live within 100 miles of work and commute (rather than drive all day in a work truck say), then an EV will likely work for you. If you do the school run and grocery shopping then head home - perfect!
I'd be interested in a reference for "scientists already know that we cannot do EV in the long term", i haven't heard that.
