Lift Energy Storage Technology: A solution for decentralized urban energy storage

The world is undergoing a rapid energy transformation dominated by growing capacities of renewable sources, such as wind and solar power. intrinsic variable nature sources calls for affordable storage solutions. This paper proposes using lifts empty apartments in tall buildings to store energy. Lift Energy Storage Technology (LEST) gravitational-based solution. stored lifting wet sand containers or other high-density materials, transported remotely out the lift with autonomous trailer devices. system requires spaces on top bottom building. An existing can be used transport from lower upper generate electricity. installed capacity cost estimated at 21 128 USD/kWh, depending height LEST particularly interesting providing decentralized ancillary services daily weekly cycles. global potential technology focused large cities high-rise around 30 300 GWh. • A new gravitational solution based operation buildings. 21–128 USD/kWh. services.
