All of this is very interesting, and I'm aware of the many challenges hydrogen is still facing./ But I think material knowledge is also improving rapidly, so perhaps we'll see some very nice new lattices to safely contain it in some compartmentalized manner. But what I meant about hydrogen was not really about cars, but heavy industry. Heavy industry is hungry and will produce its own solar, then dump it in hydrogen and burn it overnight. Then it can feed the electric cars perhaps.
