Long-Duration Storage Market Poised for $23 Billion Surge Amid Grid Challenges
Event summary
- The long-duration energy storage (LDES) market is projected to reach US$23.02 billion by 2036, from a 2026 base of US$6.34 billion.
- The market is expected to grow at a compound annual growth rate (CAGR) of 13.8% between 2026 and 2036.
- Government incentives and grid congestion are key drivers of this expansion.
- Tariffs on energy equipment are impacting costs but also spurring domestic manufacturing and supply chain diversification.
The big picture
The LDES market's rapid expansion reflects the increasing need for grid stability as renewable energy penetration rises and electrification intensifies. The projected $23 billion market size by 2036 highlights a significant shift from short-duration storage to multi-day solutions, essential for managing renewable intermittency and grid congestion. However, the ongoing impact of trade tariffs and the need for technological diversification present key challenges to sustained growth.
What we're watching
- Tariff Impact
- The long-term effect of U.S. trade tariffs on LDES component costs remains a risk, despite efforts to localize manufacturing; sustained inflation could dampen growth projections.
- Technology Adoption
- The pace at which non-lithium-ion LDES technologies achieve cost parity and scale will determine the market’s overall trajectory beyond 2030.
- Policy Alignment
- How effectively government policies evolve to support diverse LDES solutions, rather than favoring specific technologies, will shape the competitive landscape.
