We already have commercially viable batteries. Tesla sells cars as fast as they can make them, if their batteries arent commercially viable then why the hell are people still lining up to buy their products?

Solid state batteries are the closest thing but they are no where near being cost effective any time in the near future.

And hydrogen is going to be cost effective sometime soon? LOL

I know exactly how fuel cells work, as well as the processes to generate and distribute hydrogen at commercial scale, but that has nothing to do with my statement. Hell my wife (Dupont) and brother (Gore) work on competing ionomers used in the fuel cells lol.

At best you are biased toward hydrogen because you have multiple family members involved with the technology, at worst you are 100% full of shit (I would put my money on option #2).
