Grid-scale storage is the fastest-growing energy technology

By Vijay Vaitheeswaran, Global energy and climate innovation editor, The Economist

Energy storage for the electrical grid is about to hit the big time. By the reckoning of the International Energy Agency (iea), a forecaster, grid-scale storage is now the fastest-growing of all the energy technologies. In 2025, some 80 gigawatts (gw) of new grid-scale energy storage will be added globally, an eight-fold increase from 2021.
