Hydrogen does not occur naturally on Planet Earth — it has to be expensively manufactured using some other source of energy, like oil. Why not just use the oil directly in the engine?

And then hydrogen is very difficult to contain, and has relatively low energy content per unit mass or unit volume. Not so useful for vehicles.

The fuel cell is a solution looking for a problem.

Pepperidge Farms remembers.

Whatever happened to that? Where did fuel cells go? That was a technology that actually looked like it might be a path forward, but then it just sort of dropped out of the public conscious and fizzled out.

Anyone have any insight on it?
