Electricity storage is such a hot topic these days! There seems to be no end to the variety of new and old technologies being developed. Using, sand, concrete blocks, radioactive diamonds, and of course the big one: lithium ion batteries. But did you know that over 90% of current electricity storage is from a much less trendy storage technology? Pumped hydro is an energy storage solution that’s been around for over 100 years, but is in my opinion set for a resurgence in coming years as we need to add long duration energy storage to support electricity grids with large proportions of variable renewables.

A huge thank you to Andrew Blakers from the Australian National University for the information he shared with me and feedback on an early script draft! The title of this video was suggested by one of the Engineering with Rosie Patreon team. I was really struggling to think of a clickable yet accurate title, and Peter stepped up to the challenge! Big thanks to Peter and the others who suggested other good titles.
