> you are also admitting that hydrogen fuel cells are just as efficient.

You've pulled that delusion out of thin air. Fuel cells aren't batteries. Li-Ion gets ~90% conversion efficiency while fuel cells may get ~60%.

And with hydrogen that's only if you use it right after you've generated it. As soon as you need to compress and transport it, you're losing a lot more. Batteries charge from the grid, which itself has single-digit percentage losses. Hydrogen fuel cells can't do that, they have tremendous inefficiencies as the Department of Energy quote already stated.

Hydrogen fuel cells are far more expensive and vastly less efficient than batteries. There's absolutely no reason to continue to push the former when the latter is immensely practical and available today.

But you seem to ignore all information that doesn't bode well for your hydrogen dream, so I expect you'll find yet another reason to disregard this as well.

Farewell.
