I drove 1800 miles in a Hydrogen Car

Interesting, really. But since the question is very important, I will ask again, just like many below in the comments.
How do you make hydrogen and how do you safely store it?
What is the price of platinum (I heard it is rare and very, very expensive) and why?
Do you know, that your pertol/diesel car is 90% hydrogen powered? Because petrol is just a chain of hydrogen atoms bound by carbon atoms.
We are just looking to replace the the thing that stops hydrogen from going bang (carbon) with something else and make the process cleaner.
Whatever we use to make electricity is irrelevant if we always “circleback” to burning dead trees and other fossils.
Solar and wind are terribly poor solutions, nuclear is not yet popular as it should.
So... how do you make hydrogen?  Because today all that eco stuff may as well be powered by a sliced dolphin.
