they could do that when it's windy


Probably they couldn't.

Windmills don't have much return on investment for CO2.
Using them to generate a inefficient fuel like hydrogen probably wont
cut CO2.

Now using a nuke to superheat the water and then splitting it uses far
less electrical energy than electrolysis.

Also why make hydrogen when you can synthesise diesel and use existing
clean technology for the engines.
Not all diesels are filthy VWs.
