Energy storage has crossed a major threshold: annual additions exceeded 100GW for the first time in 2025. 🔋
In BloombergNEF’s latest Energy Storage Market Outlook, global deployment reached 112GW in 2025, excluding pumped hydro, up 48% from 2024, with 307GWh of batteries added worldwide.
Here are three things to know from the research:
• Energy storage surge far outpaces wind and solar growth: Annual additions of energy storage, excluding pumped hydro, reached 112GW in 2025 – up 48% from 2024. It only took four years for energy storage to increase annual additions to more than 100GW from 10GW, compared with roughly eight years for solar and 15 years for wind.
• The Iran war has yet to reach energy storage: The direct impact on energy storage markets has been limited to date, primarily due to China’s dominance in battery supply chains. Soaring fossil fuel prices could influence revenues, retail electricity prices and project costs, with impacts likely to be highly regional.
• Non-lithium chemistries gain traction: Lithium-ion batteries, especially lithium iron phosphate, accounted for more than 90% of annual additions in 2025. In 2026, long-duration energy storage is set to quadruple to 2GW, with most capacity coming from non-lithium-ion technologies. BloombergNEF also expects sodium-ion batteries to start gaining share in the stationary storage space.
