High-Density Hydro®

Better Energy Storage with 2.5 x the Power

RheEnergise’s High-Density Hydro® (HD Hydro®) is an IP protected revolution of traditional, 20th century, pumped storage hydropower (PSH). HD Hydro delivers a transformative 2.5x performance improvement above and beyond traditional PHS through the use of a patented high-density, low viscosity and environmentally benign working fluid.

As a solution provider we provide technical know-how and a fully integrated product to customers, utilising the existing global manufacturing supply chain.

At 8-hour duration, HD Hydro is half the cost of a lithium-ion battery system, (levelised cost of storage basis), without the fire risks and environmental concerns that batteries present.

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

HD Hydro® System

Next to the lower storage tanks is a powerhouse containing the pumps and turbines and anciliary plant.

Storage tanks (can be buried) are located at the top and bottom of a small hill. The storage tanks are connected by penstocks (underground pipes).

Compare with Conventional Hydro

Pumped Storage Hydropower (PSH) is a proven, bankable technology with over 100 years of operational history. However, it faces constraints severely limiting its scalability.

HD Hydro® uses hills not mountains, unlocking more than enough sites to solve the energy transition many times over.

Our innovation retains the maturity and supply chain of conventional PSH, while solving its limitations:

• Site availability
• Water abstraction
• Planning and permitting timelines
• Construction time and capital intensity
• Environmental constraints

Deployment Opportunities

Our goal is to make low-cost, low-carbon energy more widely available to consumers, while supporting grid reliability and accelerating the clean energy transition.
