Why on earth would we be cheering and advocating for "the end" of any alternative energy transportation?
Market competition is good. Exploring multiple alternatives to achieve the same goal is sound strategy.
Exploration is good and I hope research into hydrogen and fuel cells continues. The tea leaves today though, suggests that the application of this technology into personal transport is a catastrophically expensive path to pursue. Continue research and lowering the cost - absolutely. Viably implementable technology today - no.
By catastrophically expensive, I mean that if the vision is for hydrogen to replace gasoline, then there are TRILLIONS of dollars in infrastructure to build to replace the existing gasoline distribution process. Arguably, that's the easy part of the problem. There isn't a corresponding requirement for trillions of dollars of infrastructure build to support supplying electricity to a 100% EV fleet.
And the progress being shown by BEVs and battery storage suggests that fuel cells in personal transport today are many orders of magnitude behind on cost, while being many orders of magnitude behind on carbon production (more cost, to keep the same carbon production as with gas vehicles, while gaining the benefit of concentrating where the carbon emissions are produced).
Security and safety around hydrogen is simultaneously easier and harder than with gasoline. More precisely, the likelihood of a fire/explosion is dramatically lower when the properties of hydrogen are used to construct the safety equipment. The impact of a problem is dramatically higher than with gasoline. Here is a case study of an explosion at a power plant that I found very informative:
Lessons Learned from a Hydrogen Explosion
One observation - FCEV's store hydrogen at 10,000 PSI. This explosion talked about above in the case study was from hydrogen being delivered at 2400 PSI. Lowering FCEV pressure to 2400 PSI would at minimum, shorten vehicle range by 75%. Starts to sound ilke a Neighborhood FCEV, and we know how popular Neighborhood BEVs are
