The CAISO (California Independent System Operator) grid is a good example of large scale battery use (1). Texas is also seeing a ramp up of battery storage (2).

Whilst battery demand will increase it's expected costs will continue to decrease - "Innovation reduces total capital costs of battery storage by up to 40% in the power sector by 2030 in the Stated Policies Scenario"(3)

> Materials used for current storage technologies are expected to see demand skyrocket.

We haven't even specified what kind of storage technology we're talking about yet you already state that "materials used for current storage technologies are expected to see demand skyrocket". Are you referring to batteries? There are countless other technologies to "store" energy.

Eh… plutonium? I think uranium is the usual choice.

Home batteries can be part of a grid level response but this is nascent.

France, unusually, actually does, or at least did, use significant amounts of plutonium (a combo of decommissioned weapons and nuclear reprocessing output) in nuclear energy generation, but yeah, primarily uranium.
