What Is Covered Under Long Duration Energy Storage Market?

Long duration energy storage (LDES) refers to technologies that store energy for extended periods, beyond 4-6 hours, for later use. It helps balance renewable energy supply, enhance grid stability, and ensure energy resilience by storing excess power during low demand and discharging it during peak periods. The main technology types in the long duration energy storages are pumped hydro storage (PHS), compressed air energy storage (CAES), liquid air energy storage (LAES), flow batteries, and solid-state batteries. Pumped hydro storage stores energy by pumping water to a higher elevation during periods of low electricity demand and releasing it through turbines to generate electricity during high-demand periods. The storage capacities are categorized as up to 50 MW, 50–100 MW, and more than 100 MW. Duration classifications include up to 8 hours, 8–10 hours, and above 10 hours. Key applications include grid energy storage, off-grid energy storage, and backup power, with usage spanning utilities, industrial, commercial, residential, and others.

What Is The Driver Of The Long Duration Energy Storage Market?

The increasing EV charging infrastructures are expected to fuel the growth of the long-duration energy storage market going forward. EV charging infrastructure refers to the network of charging stations, including slow, fast, and ultra-fast chargers, that supply electricity to recharge electric vehicles. EV charging infrastructures are growing due to the rising adoption of electric vehicles (EVs), government incentives, advancements in battery technology, and the global push for sustainable transportation. EV charging infrastructures use long-duration energy storage to store renewable energy and provide a stable power supply during peak demand or grid outages. For instance, in April 2024, according to the International Energy Agency, a France-based intergovernmental organization, by 2030, global public charging points will exceed 15 million, a fourfold rise from 4 million in 2023, and reach 25 million by 2035, marking a sixfold increase. Therefore, the increasing EV charging infrastructures are driving the long-duration energy storage market.
