'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

That's a pretty interesting idea. Using a fluid much denser than water to turn turbines. My main concern would be what their "patented fluid" is and how much damage would be done if it leaks. EDIT: Had a look at their site and the "high tech" fluid is made of commonly available materials and is non-toxic, non-reactive and environmentally benign. Flour and water? Slime?
Plenty of non toxic materials can be pollutants in the right (wrong?) concentration and/or flowrate. Flour, while biodegradable, can eutrophize bacteria locally and create an anoxic bloom if there's enough of it.
If I were a betting man, without any further information on the initiative, I'd bet against it.
