The Long Duration Energy Storage (LDES) market is emerging as a vital enabler for the global energy transition, supporting grid stability and the large-scale integration of renewables. As power systems shift toward intermittent solar and wind, LDES technologies—capable of storing energy for 8 hours or more—are drawing intense interest from utilities, grid operators, and governments. The market’s growth is propelled by decarbonization mandates, grid modernization, and the urgent need for reliable, flexible power supply.
📊 KEY INSIGHTS
- The global LDES market is projected to grow from USD 4.84 billion in 2024 to USD 10.43 billion by 2030, at a CAGR of 13.6% during the forecast period (2024–2030).
- LDES solutions—including flow batteries, advanced compressed air, pumped hydro, and thermal storage—address the limitations of conventional lithium-ion batteries, offering multi-hour to multi-day flexibility for grid balancing and renewable integration.
- Key growth drivers:
- Rising renewable energy penetration is increasing the demand for storage that can smooth out supply fluctuations and ensure grid reliability.
