I'm struggling to argue with you when you read with your eyes shut.
Yes - battery is clean. You are releasing stored chemical energy. A dam is also a battery in definition terms and that is as green as it comes! Gravity potential energy used to spin turbines... but if you use diesel to pump the water up into the dam it's about as green as the brown coal being ripped from the earth.
Similarly, if you charge your Tesla with coal power it's being fuelled off fossil fuels. That's not green... please refer to my above comment.
Now I don't know if you did chemistry at school, but I did.
2H2O + e -> 2H2 + O2
If that energy source comes from renewables, then I don't know where you are finding this carbon from. There are no carbon molecules to be released. Electrolysis of water is a school experiment that they are aiming to apply at an industrial level using renewables. If is using energy to break bonds and create new ones that store energy and release in certain applications
