Gravity energy storage, or gravity batteries, is an emerging technology that utilizes gravitational potential energy for large-scale, sustainable energy storage. This system operates by lifting a heavy mass using energy and later releasing it to produce electricity through a. . These startups use gravitation to store energy safely for a long time and deliver it on demand at a lower lifetime cost. Unlike. . Gravity batteries function on a simple principle: lifting a heavy mass stores potential energy, and when that mass descends, the energy converts back into electricity via a generator. Unlike lithium-ion batteries, which lose efficiency over charge cycles, gravity-based storage does not degrade.

In the 1950s, flywheel-powered buses, known as, were used in () and () and there is ongoing research to make flywheel systems that are smaller, lighter, cheaper and have a greater capacity. It is hoped that flywheel systems can replace conventional chemical batteries for mobile applications, such as for electric vehicles. Proposed flywh.
