Episode description

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.
