In the latest episode of Talks with Turquoise, we shine a light on a breakthrough in long-duration energy storage that could transform how we balance renewable power.

Turquoise Managing Director Ian Thomas sits down with Stephen Crosher, CEO of RheEnergise, to explore how the company’s High-Density Hydro® (HD Hydro®) technology is reimagining the world’s dominant form of storage - pumped hydro.

Instead of relying on vast mountain ranges, RheEnergise’s solution uses a proprietary HD Fluid R-19, which is 2.5x denser than water, environmentally benign, and safe.

This innovation delivers 2.5x the power and energy of traditional pumped hydro - unlocking thousands of new project sites across smaller hills and landscapes.

With project sizes ranging from 10MW to 100MW, HD Hydro® offers a scalable, low-cost, and low-impact path to storing renewable energy at scale. RheEnergise’s technology is fast to deploy, adaptable to local geographies, and positioned to play a central role in delivering reliable, net-zero power systems worldwide.

Listen now for more on:

• How HD Hydro® works - and why density is the game-changer
