Pumped-storage hydroelectricity (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 head (elevation) and thus decreases the size an

Gravity battery

Energy from a source such as sunlight is used to lift a mass such as water upward against the force of gravity, giving it potential energy. The stored potential energy is later converted to electricity that is
