Elevator Energy Storage System''s will redefine how energy is stored in existing capital. EESS uses the power of gravity, which will never run out and has zero bi-production. The design of the EESS only requires the existing capital of an elevator so the only additional capital needed is a motor, a gearbox and some additional structural support.
Energy is stored as potential energy by elevating storage containers with an existing lift in the building from the lower storage site to the upper storage site.
Nevertheless, focusing on large cities with high-rise buildings, the researchers estimate that the global potential for the technology is around 30 to 300 gigawatt-hours.
