Grid energy storage doesn't require nickel at all. Lithium iron phosphate batteries produced at scale today do away with nickel, but they just aren't ideal for cars. There are technologies that do away with the lithium part too, but it seems like there's a new lithium discovery every few months now that we're looking, so the future is uncertain. Copper, sure. You need copper for practically everything, though. The world has run on copper since the dawn of power generation. We may see more aluminum in power transmission at some point, but barring a breakthrough in graphene composites [1], copper will be central to the electricity sector and widely extracted regardless of technology choice. 1: https://onlinelibrary.wiley.com/doi/abs/10.1002/admi.201900468 https://onlinelibrary.wiley.com/doi/abs/10.1002/admi.2019004...
