Interesting that no one thought of high density slurries for pumped hydro before now.

https://www.theengineer.co.uk/high-density-pumped-hydro/

"A new system based on pumped hydro generation promises to vastly increase
capacity to store and release energy generated from renewables, providing a
more environmentally-friendly alternative to batteries.

"The breakthrough in the system being developed by start-up RheEnergise is a
bespoke fluid with a density 2.5 times that of water. The company says this
opens up a huge number of potentially suitable sites."

83% round trip efficiency.

A really great idea!
