Long duration energy storage technologies: A comprehensive research
Author(s): Moawia Ibrahim Ahmed Hamed
Abstract: Long-duration energy storage (LDES), namely the storage technologies that have the potential of discharging as long as 8 hours or more (and up to days or seasons), is quickly gaining traction as grids without much thermal generation support high shares of variable renewable energy (VRE). LDES will focus on energy switching, staying resilient throughout multi-day low renewable events, and seasonal load balancing. This review characterizes the key classes of LDES technology (mechanical, electrochemical, fuel forming, and thermal), compares techno-economic indicators, provides a survey of demonstration projects and market signals, and lists environmental and supply-chain issues, as well as research and policy imperatives to scale LDES on an economically viable and sustainable manner. The most notable is that no one LDES technology has all the uses covered - pumped hydro in clear geographical locations is still by far the dominant, flow batteries, iron-air and hydrogen each have their market niches, and thermal stores as well as hydrogen are still being developed; that levelized cost and value is highly dependent on duration, pattern of discharge cycles, and system specifics; and risk-sharing instruments, market reforms, and coordinated RD&D are needed to bring promising technologies out of pilot to scale (IEA, 2024; NREL,2023; DOE, 2024).
