Why Energy Storage Extends Beyond Batteries
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.The key capabilities that storage should offerEnergy storage is not a single function. Systems are valued for:Duration: milliseconds to seconds (frequency control), minutes to hours (peak shifting), days to seasons (seasonal balancing).Power vs…
