The Role of Long-Duration Energy Storage in Deep Decarbonization: Policy Considerations
Summary
The briefing argues that the US requires energy storage lasting days or weeks to achieve deep decarbonization, as current technologies only provide hours of capacity. It suggests that while pumped hydro and compressed air could be extended to days, less mature technologies like hydrogen are needed for seasonal storage. The document calls for policymakers to support innovation and new financing and procurement models to enable the adoption of long-duration storage.
Key insights
- Deep decarbonization in the United States will necessitate energy storage capable of lasting days or weeks to manage multiday weather events and seasonal variations in renewable energy availability, whereas current technologies typically only provide hours of capacity.
