The present application relates to an energy storing system, which comprises a plurality of weights; a first storing unit and a second storing unit, wherein the first storing unit is arranged below the second storing unit and each of the storing units comprises a guiding track on which weights can be placed and along which weights can be moved, wherein each of said guiding tracks comprises a first portion and a second portion, wherein the second portion is arranged below the first portion; and a loading unit configured to lift at least one weight from the first storing unit to the second storing unit during a first period thereby converting electrical energy to potential energy, said loading unit further configured to lower at least one weight from the second storing unit to the first storing unit during a second period, thereby converting potential energy to electrical energy, wherein the loading unit is configured to collect a weight from the second portion of the first storing unit and to place said weight on the first portion of the second storing unit during the first period and to collect a weight from the second portion of the second storing unit and to place said weight on the first portion of the first storing unit during the second period. Further, the present invention also discloses a corresponding method. |
