For years, the challenge of storing renewable energy has been hampered by the limitations of traditional pumped hydro storage—high costs and geographical constraints. But what if there was a way to overcome these hurdles? RheEnergise, a pioneering company in the energy storage sector, has unveiled a groundbreaking hydro energy storage system called R19.
This innovative hydro energy storage system aims to transform the way we store and use renewable energy by addressing the limitations of traditional pumped hydro storage methods. By employing a high-density slurry instead of conventional water reservoirs, the R19 system offers a more accessible, cost-effective, and environmentally friendly solution for energy storage.

Traditionally, pumped hydro storage has been the go-to method for large-scale energy storage. This process involves moving water between reservoirs at different elevations to generate electricity during peak demand periods. While effective, traditional pumped hydro storage faces significant challenges:
- Geographic constraints: Large reservoirs and substantial elevation changes are required, limiting the locations where pumped hydro storage can be implemented.
- Financial barriers: The construction and maintenance of large reservoirs and associated infrastructure can be costly, making traditional pumped hydro storage financially challenging.
RheEnergise’s R19 system tackles these limitations head-on by introducing a novel approach to hydro energy storage.

The Innovative High-Density Slurry
At the heart of the R19 system lies a high-density slurry that sets it apart from conventional methods. This slurry, composed of ultra-fine solid particles and a surfactant, offers several key advantages:
- Increased energy storage density: The high-density slurry allows for smaller reservoirs and reduced height requirements, making the R19 system more versatile and adaptable to various locations.
- Lower viscosity: The combination of solid particles and surfactant maintains a lower viscosity, minimizing inefficiencies and ensuring optimal fluid flow.
- Temperature control: Precise temperature control is implemented to maintain the slurry’s properties over time, ensuring consistent performance and reliability.
By using the unique properties of the high-density slurry, RheEnergise’s R19 system opens up new possibilities for hydro energy storage.
Real-World Demonstrations and Diverse Applications
RheEnergise has already demonstrated the viability of the R19 system in real-world conditions. A successful demonstration on a ski hill in Canada showcased the system’s potential, while a planned 500 KW demonstrator in England further validates the technology’s readiness for deployment.
The R19 system’s versatility extends beyond traditional energy storage applications. It shows promise for use in mines and microgrids, where conventional pumped hydro storage may not be feasible due to geographic or financial constraints. This adaptability positions the R19 system as a fantastic option in the energy storage landscape.
Environmental and Economic Benefits
One of the most compelling aspects of the R19 system is its reduced environmental footprint. By requiring smaller reservoirs, the system minimizes its impact on the surrounding ecosystem, making it a more environmentally friendly alternative to traditional pumped hydro storage.
Moreover, the R19 system offers significant economic advantages. With a projected levelized cost of storage around $150 per megawatt-hour, it is highly competitive compared to both conventional pumped hydro and lithium-ion batteries. This cost-effectiveness makes the R19 system an attractive option for energy providers and consumers alike.
Overcoming Challenges and Future Prospects
While the R19 system holds immense potential, RheEnergise acknowledges the challenges that lie ahead. Maintaining the stability and properties of the high-density slurry over extended periods is crucial for long-term reliability. The company is actively working to address these challenges, with plans for a 10 MW grid-scale project within the next two years.
Looking to the future, RheEnergise has ambitious goals for the R19 system. The company envisions achieving 100 MW power ratings by 2030, further expanding the system’s capabilities and impact on the energy storage industry.
As RheEnergise continues to refine and scale up the R19 system, it is poised to transform the way we store and use renewable energy. By offering a more accessible, cost-effective, and environmentally friendly solution, the R19 system has the potential to accelerate the transition to a sustainable energy future.
