An energy storage and delivery system includes one or more cableways and a cage that travels along each of the one or more cableways. The cage is coupled (e.g., fixedly coupled) to one or more cables that extend between a lower elevation and a higher elevation, the cables or steel ribbons being translated along the associated cableway by a traction motor wheel to translate the cage along the associated cableway. The system is operable to pick-up, transport and deliver with the cage a plurality of blocks from the lower elevation to the higher elevation to store energy (e.g., via the potential energy of the block). The system is also operable to pick-up, transport and deliver with the cage a plurality of blocks from the higher elevation to the lower elevation at least partially under force of gravity to generate electricity via an electric generator coupled to the traction motor wheel.
