Abstract
Some embodiments relate to an energy storage and generation system, comprising a cable system having a first end portion located at a first elevation and a second end portion located at a second elevation, a plurality of mass carriers supported by the cable system, one or more motor generators coupled with the cable system and with an energy grid, a control system in communication with at least the one or more motor generators, a first mass pile area configured to store mass medium positioned at the first elevation, and a second mass pile area configured to store mass medium positioned at the second elevation that can be higher than the first elevation. The one or more motor generators can move the cable system in an energy storing state and be moved by the cable in an energy generating state. The system can store energy by transferring mass medium from the first mass pile area to the second mass pile area, and can generate energy by transferring mass medium from the second mass pile area to the first mass pile area.
