Global installed energy storage capacity by scenario, 2023 and 2030 - Chart and data by the International Energy Agency.
The rapid scaling up of energy storage systems will be critical to address the hour‐to‐hour variability of wind and solar PV electricity generation on the grid, especially as their share of generation increases rapidly in the Net Zero Scenario.
The global battery industry has been gaining momentum over the last few years, and investments in battery storage and power grids surpassed 450 billion U.S. dollars in 2024.
In 2021, 1,595 energy storage projects were operational globally, with 125 projects in construction. 51% of operational projects are located in the U.S. 10 California leads the U.S. in power capacity with 11.7 GW, followed by Texas. 8
In this multiyear study, analysts leveraged NREL energy storage projects, data, and tools to explore the role and impact of relevant and emerging energy storage technologies in the U.S. power sector across a range of potential future cost
