The question rather is, how much pumped storage do you even need when you do geographical decoupling through HVDC interconnections?
Similarly, how bound are you to the local topology? The longest already existing HVDC line in China is 3,293 km (2,046 miles). That brings you from the Rockies to any location within continental US.
Utilize renewables to have bidirectional flow compared to traditional hydro.
