You may want to look at some advancements in the Hydro world. Many of your arguments regarding Hydro sound very similar to the arguments against electric.... Just saying.... https://www.vox.com/energy-and…gy-economy-hytech-storage
Sorry but my advanced degree in engineering tells me that fuel-cell tech is a cost prohibitive, inefficient and dangerous dead-end technology. Just because the exhaust is pure water and the tech has had celebrity status in NASA does not make it right. Remember we are talking about a compressed tank of explodable gas stowed in a car, okay. What part of ass-backward does this not show?
Battery electric vehicles that can be purely supported by renewable energy (in one own's home for pete's sake) and is currently in use in 100s of thousands of cars with a proven track record (of close to 15 years) tells me it's the right way to go. It's foolish to invest into fuel-cell, Honda now realizes this and Toyota will soon follow suit.
No way is this similar to the dead-end and dangerous tech of fuel cell.
Come on use common sense, why would you introduce a combustible gas into a electrical system that already gets the job done (and very efficiently at that).
That article you cite continuously throws in diesel as a comparison as if to make fuel cell look better since anything next to diesel does look better and cleaner by default.
This article smacks of big oil propaganda to push hydrogen gas. Because in the end you will still need to supplement additional fuel sources to get enough electrical current to produce hydrogen gas in viable quantities which defeats the purpose of just relying on renewable energy..
