Pumped hydroelectricity is geographically dependent - you need a valley or mountain that you can dam up to build pumped hydro. While it may be great for South Australia, the region examined in your linked paper, it's wrong to assume that this availability is uniform.
- nl 6y agoThe available isn't uniform, but it sure is widespread! "The perception has been there are limited sites for pumped hydro around the world, but we have found hundreds of thousands." https://www.anu.edu.au/news/all-news/anu-finds-530000-potential-pumped-hydro-sites-worldwide https://www.anu.edu.au/news/all-news/anu-finds-530000-potent...
- manfredo 6y agoThis paper just ran an algorithm over a heightmap, and pinpointed potential reservoirs. This is a far cry from actually identifying feasible sites. The massive density of hydroelectric storage in the Himalayas, for instance, is far too remote to be developed at anything approaching reasonable cost. Not to mention, it still leaves swathes of places like Central north America, and much of Northern Europe without access to hydroelectric storage.
