RheEnergise is bringing fresh innovation to the world’s dominant form of storage: pumped hydro storage. We call our solution High-Density Hydro®. HD Hydro® uses our proprietary HD Fluid R-19 which has 2.5x the density of water. It is environmentally benign, non-toxic, non-corrosive, and non-reactive. R-19 gives RheEnergise projects 2.5x the power and 2.5x the energy when compared to water. Unlike traditional pumped hydro energy storage, HD Hydro can operate using smaller hills as opposed to needing mountains. As a result, it opens up vastly more options in terms of potential sites. The technology is sized in the range of 10MW to 100MW, and 20MWh to 200MWh. HD Hydro is the best option for meeting society’s energy storage needs; compared to the competition it is agile and fast to deploy, massively scalable, has low impact, low cost, and low risk. RheEnergise consists of a highly experienced team with a strong track record in renewable energy, engineering, finance and bringing innovation to market.
