Exploring Energy Storage Beyond Battery Limitations
The public discourse equates energy storage with lithium-ion batteries, and for good reason: batteries have enabled rapid advances in grid flexibility, electric vehicles, and distributed energy systems. Yet a comprehensive energy transition requires a broad portfolio of storage technologies. Different storage forms deliver varied durations, scales, costs, environmental footprints, and grid services. Treating storage as a single-technology problem risks technical mismatches, economic inefficiencies, and missed opportunities for resilience.What “storage” must deliverEnergy storage serves more than one purpose. Systems are evaluated based on:Duration: spanning milliseconds to seconds for frequency regulation, minutes to hours for peak shifting, and days up to entire…
