Why Energy Storage Extends Past Batteries
Public debate often associates energy storage with lithium-ion batteries, and understandably so, as these batteries have driven swift progress in grid flexibility, electric vehicles, and decentralized energy systems. However, achieving a full energy transition demands a diversified suite of storage technologies. Distinct storage methods offer different durations, capacities, costs, environmental impacts, and grid-support functions. Viewing storage as a one-technology issue can lead to technical mismatches, economic drawbacks, and lost chances to strengthen 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,…
