What's the deal with pumped-hydro energy storage?

In this episode, I talk with Erik Steimle of Rye Development
about the new wave of "closed loop" pumped-hydro storage
projects. Unlike traditional systems that rely on rivers and
dams, these projects use two artificial reservoirs — providing
reliable long-duration storage without impacting natural
waterways. We explore the economics of these billion-dollar
facilities, their 100+ year lifespans, and how they compare to
lithium-ion storage.
