Grid-scale storage traditionally relied on hydroelectric systems that moved water between reservoirs at the top and bottom of a slope. These days giant batteries stacked in rows of sheds are increasingly the method of choice. According to the IEA, 90GW of battery storage was installed globally last year, double the amount in 2022, of which roughly two-thirds was for the grid and the remainder for other applications such as residential solar. Prices are falling and new chemistries are being developed. Bain, a consultancy, estimates that the market for grid-scale storage could expand from around $15bn in 2023 to between $200bn and $700bn by 2030, and $1trn-3trn by 2040.
