Long-Duration Energy Storage Maximizes Renewable Utilization and Delivers Rapid, Cost-Effective Carbon Reductions

Description and Background: Today, regions that have led the deployment of renewable capacity are experiencing a side effect of their success: curtailment when supply outstrips demand and shortfalls when sun is not shining and wind is not blowing. Curtailment of renewable assets represents lost opportunities for clean energy, carbon reductions and revenue. Meanwhile, fossil generation fills the gap, continuing to emit carbon. Adding long-duration energy storage (LDES) to the grid enables excess generation to be captured when renewable resources are plentiful and deployed when needed to enable the retirement of fossil generation and deliver a decarbonized energy system.
