I would love to know how anyone, nameless troll or otherwise, can be so stupid, as to try to use energy density as the basis of attempts to smear the reputation hydrogen, which is an impersonal element in the first place. It isn't a human, it's the most common, most fundamental element in the universe, it's the fuel of the fusion reactor that is the sun, fuel of gods and all life, and yet you appear to hate it, as if it was a human. who threatened the income you might make from oil.
Its 3x the energy density of the closest fossil fuels by nature, atomic structure, undeniable, look it up in an actual reference.
A hydrogen powered concorde would fly all the way to Australia from London, instead of just to new York, with the same mass of fuel.
That is what we will have by solar powered hydrogen whether you like it or not.
So butt out, poisonous lying troll.
