Why the Future of Energy Storage is in Gravity
Gravity batteries are a lot like flywheels in that they store energy as potential energy. It''s as simple as lifting a really heavy object to store energy and then dropping it when the energy needs to be released. A company that is currently doing this on a very large scale is a start-up in Edinburgh, U.K. called Gravitricity.
