READ MOREcolintbowers. • 2 yr. ago. The best gravitational batteries currently are hydro. That is, pump water uphill, then power a turbine with it when it comes down. This tech can perform incredibly well at large scale (I''ve heard some pretty crazy small loss figures from the large plants in California).
READ MOREThe basic idea behind a gravity battery system is lifting a heavy object using energy from other sources such as a large mass of concrete or a weight high into the air, to the top of a deep shaft, on a pulley, letting it fall when energy is needed and converting its potential energy into electricity using an electric generator. This is often

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
