Superconducting magnetic storage: Overview

Storing energy in a magnetic field with zero electrical resistance

What this tile covers Energy held in the magnetic field of a superconducting coil. Share of use 0% share of world stored energy (2026)

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 No grid-scale superconducting magnetic stores are in commercial service; demonstrators hold megajoules. Effectively zero.
