Devon project revives century-old hydro idea with high-density fluid for renewable energy storage

Summary

A Devon-based project called RheEnergise is reviving a century-old hydroelectric concept using a high-density fluid (minerals mixed with water, 2.5x denser than water) to store renewable energy. Unlike traditional pumped hydro that requires mountains and large reservoirs, this system uses smaller underground tanks and can be deployed in hills and former mines. The demonstrator project near Plymouth shows how the dense fluid generates power by flowing downhill through turbines, offering a more flexible and compact solution for energy storage to help address the energy crisis.
