When I overlay the population density map, on top of the elevation map. I think there aren’t many opportunities in Texas for grid scale pumped hydro storage. Although pumped hydro has huge potential it is not homogeneously distributed all over the world according to this map. https://www.hydroreview.com/world-regions/22-million-gwh-of-...

Bill Gates mentioned pressurized pumped-hydro storage in his book, (which was the first I had heard of it), and it sounds quite promising and something Texas is well-suited for:

> GLIDES costs as low as $13/kWh and $346/kWh and roundtrip efficiencies as high as 80% can be achieved using depleted oil/gas reservoirs and high-pressure pipe segments as pressure reservoirs, respectively.
