How are they going to store the power? Unless it’s all used I guess. Because battery storage technology isn’t efficient enough yet.

They’re using redox flow batteries. The tech is nowhere the energy density of lithium but it’s meant to supplement the traditional power grid at night time. It’s got similar characteristics of a pumped hydro solution except less efficient.

They're building tons of pumped hydro and about a dozen other various energy storage solutions

They might not have to since wind will likely still blow at night and you have solar during the day for peak usage. They will need excess capacity however for low output days.
