OPENTECHNICAL PUBLICATION OT-2026-000002090 Energy storage and delivery system with an elevator lift system and method of operating the same Published: 2026-09-15T19:10:44.646856Z Permanent URL: https://opentechnical.org/p/OT-2026-000002090 Categories: Lifting, Positioning & Manipulation > Hoists and Cranes ------------------------------------------------------------------------ ABSTRACT An energy storage and delivery system includes an elevator operable to move blocks from a lower elevation to a higher elevation to store energy and from a higher elevation to a lower elevation to generate electricity. A winch assembly is movably coupled to a cable that is coupled to the elevator. The winch assembly has planetary gear assemblies, brakes that selectively engage at least a portion of the planetary gear assemblies, and a spool coupled to the cable. A drive shaft extends between a motor-generator and the winch assembly. A brake is operable so that the spool rotates to reel-in the cable to raise the elevator to move a block from a lower elevation to a higher elevation to store energy or so that the spool rotates to reel-out the cable to lower the elevator to move a block from a higher elevation to a lower elevation to generate electricity. ------------------------------------------------------------------------ OpenTechnical publication OT-2026-000002090 Published 2026-09-15T19:10:44.646856Z https://opentechnical.org/p/OT-2026-000002090
