Powering up: UK hills could be used as energy 'batteries'

Engineers explore using gentle slopes rather than steep dams or mountains to store electricity

RheEnergise is bringing innovation to pumped hydro storage. We call our new solution High-Density Hydro „¢.

HD Hydro „¢ uses our proprietary HD Fluid R-19 „¢, which has 2.5x the density of water. R-19 gives RheEnergise projects 2.5x the power and 2.5x the energy when compared to water.

I wonder what their proprietary HD Fluid R-19 „¢ actually is?

They claim: Our innovative fluid R-19 TM is environmentally benign and has been engineered to be non-reactive and non-corrosive.


" Chief executive Stephen Crosher told Professional Engineering that the
liquid is a fine-milled suspended solid in water, with low viscosity and
low abrasion characteristics. The base material is used in oral
medication applications, in a similar way that chalk is used as a
bulking agent for pills and tablets. He said the raw materials are
common and available, including in the UK, and the fluid could either be
manufactured on-site or at a depot. "
