Long-term logistics energy storage

How do you compare long-duration energy storage technologies (LDEs)?

Review commercially emerging long-duration energy storage technologies (LDES). Compare equivalent efficiency including idle losses for long duration storage. Compare land footprint that is critical to market entry and project deployment. Compare capital cost-duration curve.

What are long-duration energy storage technologies?

In this paper, we loosely define long-duration energy storage technologies as ones that at minimum can provide inter-day applications. Long-duration energy storage projects usually have large energy ratings, targeting different markets compared with many short duration energy storage projects.

How long should energy storage last?

Therefore, the need for storage with durations of 10 or more hours largely hinges on a future grid with a specific set of conditions including regional load patterns, renewable energy deployment, previous storage deployments, and the economics of competing storage options.

How does the technology landscape affect long-duration energy storage?

The technology landscape may allow for a diverse range of storage applications based on land availability and duration need, which may be location dependent. These insights are valuable to guide the development of long-duration energy storage projects and inspire potential use cases for different long-duration energy storage technologies.

Should long-duration energy storage be qualitative or quantitative?

To address this issue, the National Renewable Energy Laboratory recommends that qualitative descriptions of long-duration energy storage always be accompanied by quantitative descriptions, and that power sector stakeholders be deliberate in how they choose to define long-duration energy storage technologies.

Can small TPV storage be used for long-duration energy storage?

Having smaller footprints for emerging technologies may inspire new business models (e.g., modular distributed storage) for long-duration energy storage to enter the market. For example, small TPV storage options such as those developed by Antora Energy are likely to support more flexible sizing and siting with smaller minimum footprints.
