Long Duration Energy Storage Market Report 2025

The long duration energy storage market size has grown rapidly in recent years. It will grow from $3.12 billion in 2024 to $3.58 billion in 2025 at a compound annual growth rate (CAGR) of 14.7%. The growth observed in the historic period can be credited to the rising interest in decentralized energy systems, increased awareness of climate change, heightened concerns about energy security, the growing need for grid flexibility, and intensified energy transition efforts.

The long duration energy storage market size is expected to see rapid growth in the next few years. It will grow to $6.15 billion in 2029 at a compound annual growth rate (CAGR) of 14.5%. The anticipated growth during the forecast period can be attributed to the increasing global demand for clean and affordable energy, the expanding electrification of economies, higher investments in clean energy infrastructure, mounting pressure to achieve net-zero emissions, and a growing focus on long-term energy security. Key trends expected in this period include advancements in battery technologies, innovative storage materials, enhanced hybrid storage systems, improved case systems, and sophisticated control systems.

The expansion of EV charging infrastructure is expected to drive the growth of the long-duration energy storage market. EV charging infrastructure includes a network of stations with slow, fast, and ultra-fast chargers that provide electricity for recharging electric vehicles. The growth of this infrastructure is fueled by the increasing adoption of electric vehicles (EVs), government incentives, advancements in battery technology, and the global push toward sustainable transportation. Long-duration energy storage is used in EV charging infrastructure to store renewable energy and ensure a stable power supply during peak demand or power outages. For example, according to a report from the International Energy Agency, published in April 2024, the number of global public charging points is projected to surpass 15 million by 2030, a fourfold increase from 4 million in 2023, and reach 25 million by 2035, marking a sixfold rise. This growth in EV charging infrastructure is driving the demand for long-duration energy storage.

Long Duration Energy Storage (LDES) refers to technologies that store energy for extended periods, typically beyond 4-6 hours, for later use. These systems help balance renewable energy supply, enhance grid stability, and ensure energy resilience by storing surplus power during low-demand periods and discharging it when demand is high.

The main LDES technologies include pumped hydro storage (PHS), compressed air energy storage (CAES), liquid air energy storage (LAES), flow batteries, and solid-state batteries. Pumped hydro storage works by pumping water to a higher elevation during low electricity demand and releasing it through turbines to generate power during peak demand. Storage capacities are categorized as up to 50 MW, 50-100 MW, and more than 100 MW, with duration classifications of up to 8 hours, 8-10 hours, and above 10 hours. Key applications include grid energy storage, off-grid energy storage, and backup power, serving sectors such as utilities, industrial, commercial, and residential markets.
