# Gravity storage: Overview

Storing power by lifting concrete blocks and lowering them later

Source page: https://www.materialinsights.org/energy/e_gravity/overview/

What this tile covers Lifting heavy weights and lowering them to make power. Share of use <.01% share of world stored energy (2024)

Share of the world's stored energy (energy capacity held, TWh, latest year 2019 to 2026) across the forms with figures, about 22,551 TWh; fuel stocks dominate. Battery and other stores count capacity, not state of charge The 25 MW / 100 MWh Rudong plant in China is the only grid-scale gravity store connected; three more were under construction in 2024. About 0.1 GWh.
