I've just linked to the current reality - large operators (eg: people that meet the global steel demand by delivering ~ one billion tonne of iron ore per year via operating large fleets of diggers, trucks, trains, etc 24/7/365) have already built and are building out more green hydrogen infrastructure and investing serious money into better electrolysers, etc.

With an excess of sunlight hydrogen can be used to generate electricity at night to recharge mobile equipment batteries and cable powered semi mobile equipment, with conversion of hydrogen to ammonia it can be bulk shipped to large scale generation plants elsewhere.

Not especially relevant here to the current reality of large scale green hydrogen generation for direct industrial application to reduce greenhouse gas emmissions though, is it?

Californians struggling with small cars doesn't negate what else is happening in our current reality.
