'No-water' hydropower turns England's hills into green and pleasant batteries
Technology based on dense fluid said to open up 'massive opportunities' in mountain-light English countryside and around the world

Very cool. Do we know what the fluid is? Does it pose any health risks if it somehow leaks into the groundwater?
It's just good ol' fashioned mercury.
The article claims it's 2.5x as dense as water, which according to this density chart is probably bromine.
I actually bet it's just very very fine stonedust and water in suspension.
I'm not sure which would be worse for the machinery
Supposedly it's exactly that, but stabilized by a polymer to keep it in suspension for up to 60 days without mixing. https://online.flippingbook.com/view/1025707592/10/#zoom=true
Edit: I've concluded it's likely calcium carbonate.
rotor blades are going to love this
Our innovative fluid R-19 is environmentally benign and has been engineered to be non-reactive and non-corrosive.
They're saying it's minerals and a polymer. In that case even a leak into groundwater would just be leaking groundwater. (Depending on what the polymer is)
