The ANU found more than six hundred thousand potential sites around the world where closed loop pumped hydro systems could work, 00:07:29 at least from a geographical and topographical point of view anyway, representing a potential of about twenty-three million gigawatt hours of energy storage, which would be about a hundred times what we’d need for a one hundred percent renewable powered global electricity system. Now, obviously not all of those sites will turn out to be appropriate, so we need to keep our feet well and true planted on the ground here. The ANU itself points out that, apart from discounting any 00:07:56 urban areas and known areas of environmentally protected zones, no other comprehensive geological, hydrological, environmental, or heritage studies were carried out as part of their research project, so it’s highly likely that only a relatively small percentage will prove to be viable. But, even if it’s only one percent, that still gets us over the line, doesn’t it?
- for: pumped storage hydro, pumped hydro, pumped storage, PSH, ANU study, ANU PSH
- stats
- 23 million gigawatt-hours of global PSH
- sites in the study were
- geographically and topographically feasible
- non-urban areas
- environmentally protected areas
- this is 100x more than is needed for a global 100% renewable energy storage system
- so even if only 1% of sites were useful, that is enough to provide all we need for global 100% renewable energy storage
