Energy storage: 5 trends to watch in 2025
The scene is set for significant energy storage installation growth and technological advancements in 2025. Outlook and analysis of emerging
Global installed energy storage is on a steep upward trajectory. From just under 0.5 terawatts (TW) in 2024, total capacity is expected to rise ninefold to over 4 TW by 2040, driven by battery energy storage systems (BESS). Last year saw a record-breaking 200 gigawatt-hours (GWh) of new BESS projects coming online, a growth rate of 80%.
Evaluating potential revenue streams from flexible assets, such as energy storage systems, is not simple. Investors need to consider the various value pools available to a storage asset, including wholesale, grid services, and capacity markets, as well as the inherent volatility of the prices of each (see sidebar, “Glossary”).
In 2024, the global energy storage is set to add more than 100 gigawatt-hours of capacity for the first time. The uptick will be largely driven by the growth in China, which will once again be the largest energy storage market globally.
By means of technical economics, the potential value and development prospects of energy storage technologies can be revealed from the perspective of investors or decision-makers to better facilitate the deployment and progress of energy storage technologies.
Last year's record global additions of 45 gigawatts (97 gigawatt-hours) will be followed by continued robust growth. In 2024, the global energy storage is set to add more than 100 gigawatt-hours of capacity for the first time.
Global electricity output is set to grow by 50 percent by mid-century, relative to 2022 levels. With renewable sources expected to account for the largest share of electricity generation worldwide in the coming decades, energy storage will play a significant role in maintaining the balance between supply and demand.
