EIA projects that battery storage capacity will grow to make up between 4% and 9% of global power capacity by 2050. [pdf]
Across all scenarios in the study, utility-scale diurnal energy storage deployment grows significantly through 2050, totaling over 125 gigawatts of installed capacity in the modest cost and performance assumptions—a more than five-fold increase from today’s total.
Depending on cost and other variables, deployment could total as much as 680 gigawatts by 2050. The chart has 1 Y axis displaying Storage Capacity (GW). Data ranges from 0.038 to 212.68973701349. The chart has 1 Y axis displaying Storage Capacity (GW). Data ranges from 22.829203 to 383.700851650059. “These are game-changing numbers,” Frazier said.
In 2030, annual deployment of battery storage ranges from 1 to 30 gigawatts across the scenarios. By 2050, annual deployment ranges from 7 to 77 gigawatts.
Participation and utilisation rates of 50% for vehicle-to-grid and second-use, results in a real-world capacity of 25–48 TWh by 2050, far higher than the short-term storage requirements estimated from the literature.
We include both in-use and end-of-vehicle-life use phases and find a technical capacity of 32–62 terawatt-hours by 2050. Low participation rates of 12%–43% are needed to provide short-term grid storage demand globally. Participation rates fall below 10% if half of EV batteries at end-of-vehicle-life are used as stationary storage.
Until 2050, costs are projected to drop to around USD 135/kWh in all scenarios ( , p. 473), with costs in the STEPS slightly above this value and costs in the APS and NZE Scenario slightly below.

The pledge, which was proposed by the COP29 Presidency, calls on governments and non-state actors to commit to a deployment target of 1,500 GW of energy storage, doubling grid investment and the development of 25 million kilometres of grid infrastructure by 2030.

BNEF forecasts energy storage located in homes and businesses will make up about one quarter of global storage installations by 2030. Yayoi Sekine, head of energy storage at BNEF, added: “With ambition the energy storage market has potential to pick-up incredibly quickly.
At the Summit, DOE will launch Storage Innovation 2030 to develop specific and quantifiable RD&D pathways to achieving the targets identified in the Long Duration Storage Energy Earthshot. Industry representatives are encouraged to register to present.
New York, October 12, 2022 – Energy storage installations around the world are projected to reach a cumulative 411 gigawatts (or 1,194 gigawatt-hours) by the end of 2030, according to the latest forecast from research company BloombergNEF (BNEF). That is 15 times the 27GW/56GWh of storage that was online at the end of 2021.
SI 2030, which was launched at the Energy Storage Grand Challenge Summit in September 2022, shows DOE’s commitment to advancing energy storage technologies.
By 2025, the large-scale commercialization of new energy storage technologies 1 with more than 30 GW of installed non-hydro energy storage capacity will be achieved; and by 2030, market-oriented development will be realized [ 3 ].
In July 2021 China announced plans to install over 30 GW of energy storage by 2025 (excluding pumped-storage hydropower), a more than three-fold increase on its installed capacity as of 2022.
