Energy systems need to decarbonise to prevent climate change. There are many solutions to generate energy without using fossil-fuels, but renewable sources of energy are intermittent, leading to a mismatch between supply and consumer demand.

Energy storage is the solution.

RheEnergise is bringing innovation to pumped energy storage, with our solution called High-Density Hydro®.  Our projects use a fluid with 2.5x the density of water, meaning that they can be installed on small hills instead of mountains.

Benefits

High-Density Hydro® is a scalable and cost-effective energy storage solution which offers the following:

1. Low Cost: Building on over a hundred years' experience with the most widely used form of energy storage means low risk and an established industry to leverage deployment. Being 2.5x smaller, by volume, means dramatically lower construction costs, faster build times, easier reinstatement and easier landscaping.

2. Agile: By innovating in the high-density fluid (R-19) we use, we unlock many hundreds of times more suitable sites. Projects can be installed on hills 2.5x lower than a project using water and still achieve the same power – for example there are so many more hills at 150m than at 300m.

3. Clean : Our innovative fluid R-19 is non-toxic and has been engineered to be non-reactive and non-corrosive. Our plants require smaller footprint and have minimal recyclability and supply chain considerations. 

RheEnergise’s energy storage solution incorporates innovations, including new IP, across six sub-systems:

The Technology

The concept is simple. At times of low demand, when energy prices are low, the High-Density Fluid R-19™ is pumped to the top storage tanks.

As demand goes up and energy prices rise, the HD Fluid R-19™  is released and it passes through turbines, regenerating electricity to supply power to the grid.
