The global long-duration energy storage (LDES) market is forecast to expand significantly over the next decade, growing from an estimated US$6.34 billion in 2026 to US$23.02 billion by 2036, representing a compound annual growth rate of 13.8 percent. This expansion reflects structural shifts in energy infrastructure as utilities and grid operators increasingly prioritize multi-day storage capabilities to manage renewable energy variability and address capacity constraints.
The market's growth trajectory is underpinned by several converging factors, including accelerated renewable energy deployment across major economies, persistent grid congestion in high-demand regions, and an expanding policy framework supportive of energy storage investments. Governments worldwide have introduced incentives and regulatory mechanisms designed to facilitate long-duration storage adoption as a critical component of decarbonization strategies.
Near-term cost pressures stemming from U.S. tariffs on battery components and critical minerals present a near-term headwind for the sector. However, these trade measures are simultaneously catalyzing domestic manufacturing capacity expansion, particularly in North America, which may reshape supply chain dynamics and regional competitiveness in long-duration storage technologies over the forecast period.
