This technology, which transforms excess electricity into gravitational potential energy, offers an environmentally friendly, long-duration storage option that could complement and even, in some cases, rival conventional battery systems.

(PSH) is the most widely used and highest-capacity form of grid-energy storage. In PSH, water is pumped from a lower reservoir to a higher reservoir, which can then be released through turbines to produce energy. An alternative PSH proposal uses a proprietary high-density liquid, 2+1⁄2 times denser than water, which requires a smaller (elevation) and thus decreases the size an.
