Turning electricity into hot and cold, then back again
What this tile covers Electricity stored as heat and cold, then turned back into electricity. 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 Pilot scale only; SPIC's 1 MW / 4 MWh pilot is used as the order of magnitude. Near zero.
