Thing about batteries is.

From an environmental standpoint, both mining the raw materials and producing the batteries uses a lot of energy and produces a lot of pollution.

Morally, many raw materials for batteries come from desperately poor conflict zones, so you have megacorps staffing mines with slavery and child labor, paying local warlords/dictators for permission to operate, having those warlords/dictators kill protesters and union organizers, etc.

If we can get a hydrogen economy working, and the equipment and technology don't need conflict minerals or polluting heavy industry to manufacture, it would be a boon for the world both practically and morally.

But that's a big if.
