Long-term non-lithium energy storage technology development

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.

Are lithium-ion batteries good for long-duration applications?

While lithium-ion batteries dominate the energy storage market, they are not always the best fit for long-duration applications.

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.

Are long-duration energy storage technologies environmentally sound?

Ongoing research is critical to ensuring that long-duration energy storage technologies are environmentally sound, as well as expanding the methods that can be used to store energy.

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.

Are long-duration energy storage technologies a stabilizer for new power systems?

Long-duration energy-storage technologies: A stabilizer for new power systems. The Innovation Energy 2:100077. Against the backdrop of realizing the target of “carbon peak and carbon neutrality”, renewable energy sources such as wind and solar power have developed rapidly.
