Energy storage market seen reaching $226.2B by 2035

The global energy storage market is projected to jump from $39.2 billion in 2026 to $226.2 billion by 2035, driven by policy support in the U.S. and China, falling battery costs and rising demand for grid flexibility. Asia-Pacific held nearly half of installed capacity in 2025, with China responsible for more than half of regional deployments.

Why it matters: - Energy storage is becoming core grid infrastructure as utilities and governments push for more renewable power, more reliable electricity and less dependence on gas peaker plants. - The market forecast points to a major capital shift, with storage moving from a niche reliability tool to a revenue-generating asset class. - The report projects the market will rise from $39.2 billion in 2026 to $226.2 billion by 2035, a 21.5% compound annual growth rate.

What happened: - The market reached an estimated $32.4 billion in 2025. - The report says the U.S. Inflation Reduction Act’s standalone storage investment tax credit unlocked about $7.5 billion in project financing in its first 18 months. - China’s 14th Five-Year Plan requires provinces to pair at least 10% of new renewable capacity with multi-hour storage. - Asia-Pacific held 48.3% of installed capacity in 2025, with China accounting for more than half of regional deployments. - China installed more than 48 GWh of new storage capacity in 2024, more than the rest of the world combined.

Between the lines: - Policy is doing more than subsidizing deployment. It is changing how storage earns money, especially by combining energy arbitrage, ancillary services and capacity payments. - Falling LFP costs are reshaping the technology mix toward standard battery systems for four-to-six-hour use cases. - Longer-duration options such as hydrogen, iron-air and zinc-bromine are getting attention because batteries still struggle to compete economically for seasonal balancing and very long discharge windows. - Grid congestion, permitting delays and interconnection backlogs may slow projects even as demand accelerates.

What's next: - Long-duration storage technologies are approaching commercial feasibility for discharge periods above eight hours. - Form Energy is targeting $20/kWh for 100-hour storage by 2028. - AI-driven storage platforms are expected to handle degradation-aware cycling, predictive maintenance and multi-market bidding by 2030. - The report says these software gains could lift storage revenues by 15% to 25% versus rule-based control systems. - Global electricity demand is forecast to grow 3.4% annually through 2035, adding more pressure for flexible capacity. - Green-bond issuance for storage projects exceeded $8 billion in 2024, signaling continued financing support.

The bottom line: - Energy storage is moving from an emerging clean-energy add-on to a central power-system asset, with policy support, lower battery costs and grid reliability needs driving the next decade of growth.
