Pumped hydro constitutes about 97% of all energy storage. We found 22,000 off-river pumped hydro sites in Australia with energy storage potential of 67 Terawatt hours, which is about 150 times more than required to support a 100% renewable electricity grid. We modelled a 100% renewable electricity system for Australia and found that the cost of …
