In this design, pioneered by the California based company Advanced Rail Energy Storage (ARES) company in 2010 ARES North America (ARES North America - The Power of Gravity, n.d., Letcher, 2016), the excess power of the renewable plants or off-peak electricity of the grid is used to lift some heavy masses (concrete blocks here) by a
What You Should Know About Gravity Energy Storage
Gravity energy storage harnesses gravitational energy in a storage device. For instance, gravity energy utilizes stacked concrete blocks or other heavy materials, pulling excess energy from the electric grid. Potential energy increases as the objects or blocks rise. Conversely, as they''re lowered, the potential energy decreases
