National storage targets fall 45% short of COP29 global pledge
Ember analysis shows current national storage targets total 822 GW by 2030, significantly lagging the 1,500 GW committed at COP29. While 2025 additions reached 118 GW, maintaining current rates would still leave the global goal unmet.
National energy storage targets currently total 822 GW by 2030, according to Ember. This figure stands in stark contrast to the global pledge made at COP29, which commits to 1,500 GW of energy storage capacity by the same year. As reported by pv magazine USA, these existing national plans are 45% below the international commitment.
The gap highlights a significant shortfall in current policy frameworks relative to the agreed-upon global goal. While the COP29 pledge sets a clear benchmark for 2030, the aggregated national targets fall well short of that mark. This discrepancy suggests that individual country strategies have not yet aligned with the broader international consensus on the scale of storage deployment required.
The data underscores the distance between current national ambitions and the collective target established at the climate summit. Closing this 45% deficit will require substantial policy adjustments and accelerated investment across multiple markets to meet the 1,500 GW threshold.
Recent Capacity Additions
Global energy storage capacity reached 430 GW at the end of 2025. This total reflects the cumulative build-out of systems designed to balance supply and demand on modern power grids. As renewable generation grows, such infrastructure becomes essential for managing variable output and enhancing grid stability. The figure represents a substantial increase in the world’s ability to store excess electricity for later use.
During 2025, the sector added 118 GW of new capacity. This annual growth rate indicates a significant acceleration in deployment compared to previous years. The rapid expansion suggests that policy incentives and falling technology costs are driving widespread adoption. Grid operators and utilities continue to prioritize storage to address peak demand challenges and improve reliability.
Batteries accounted for 108 GW of those 2025 capacity additions. This dominance highlights the central role of electrochemical storage in the current market. Battery systems offer fast response times and flexible deployment options, making them suitable for various grid services. The remaining capacity likely consists of other technologies, though batteries clearly lead the recent installation wave. This trend underscores the industry’s focus on versatile, scalable solutions for near-term grid needs.
Regional Installation Shares
- China accounted for 54% of new storage installations globally in 2025.
- The United States represented 16% of new storage installations in 2025.
These two markets collectively drove the majority of the world's recent expansion, with China alone installing more than half of all new capacity added during the year. This concentration reflects the scale of domestic renewable integration efforts and industrial policy priorities in the region, which have accelerated deployment well beyond earlier forecasts. For grid operators, such rapid build-out in a single jurisdiction provides a massive buffer against supply variability, though it also concentrates manufacturing and supply chain dependencies in specific geographic areas.
The United States contributed a significant but smaller share, indicating a steady but less dominant pace of adoption compared to its largest peer. This disparity highlights how national policy frameworks and market signals can produce vastly different deployment trajectories, even among major economies. Investors and developers tracking global trends must recognize that regional dynamics, rather than a uniform global rollout, are shaping where new infrastructure emerges. Understanding these shares is essential for anticipating where grid services will be most abundant and where further policy intervention might be needed to balance the global portfolio.
National Target Revisions
Recent policy shifts reveal a fragmented approach to meeting the 2030 global benchmark. While some jurisdictions have dramatically scaled up their ambitions, others have adjusted their forecasts based on current market conditions. The table below summarizes the latest national and regional targets.
| Jurisdiction | 2030 Storage Target |
|---|---|
| China | 460 GW |
| European Union | 200 GW |
| Australia | 33 GW |
| Spain | 22.5 GW |
| Vietnam | 22.3 GW |
China’s revision stands out, as the country increased its 2030 storage target from 130 GW to 460 GW. This substantial upward adjustment reflects the scale of domestic renewable integration and the need for grid stability as variable generation expands. In contrast, the European Union adopted a 200 GW target in June 2026, signaling a coordinated regional commitment to scale up infrastructure. Australia revised its 2030 storage projection to 33 GW, a figure that likely reflects updated assumptions about domestic generation mix and demand patterns. Meanwhile, Vietnam set a 2030 storage target of 22.3 GW, while Spain maintains a 22.5 GW target. These figures illustrate how national strategies vary widely, driven by distinct energy mixes, policy priorities, and market structures. For developers, this diversity implies that project economics and regulatory environments will differ significantly across markets, requiring tailored strategies for investment and deployment.
What to watch
The central question for the next five years is whether deployment can bridge the widening gap between current national plans and the 1,500 GW global benchmark. BloombergNEF forecasts 1,200 GW of global battery storage capacity by 2030, a projection that still falls short of the COP29 pledge. This estimate reflects expected growth in major markets but assumes no sudden policy shifts or technological breakthroughs that would accelerate construction beyond current trajectories.
Maintaining 2025 installation rates would reach 1,020 GW by 2030, a figure that highlights the distance between historical momentum and future requirements. For grid operators and investors, the divergence between these two scenarios underscores the need for sustained policy support and capital allocation. If installation rates plateau, the sector risks falling further behind the pace required to support high-penetration renewable grids. Monitoring whether new national targets translate into actual procurement and construction timelines will be essential for assessing if the 45% shortfall can be closed before the decade ends.
