Do charge power and energy storage capacity investments have O&M costs?

We provide a conversion table in Supplementary Table 5, which can be used to compare a resource with a different asset life or a different cost of capital assumption with the findings reported in this paper. The charge power capacity and energy storage capacity investments were assumed to have no O&M costs associated with them.

Can energy storage technologies help a cost-effective electricity system decarbonization?

Other work has indicated that energy storage technologies with longer storage durations, lower energy storage capacity costs and the ability to decouple power and energy capacity scaling could enable cost-effective electricity system decarbonization with all energy supplied by VRE 8, 9, 10.

What is long-duration energy storage (LDEs)?

Provided by the Springer Nature SharedIt content-sharing initiative Long-duration energy storage (LDES) is a potential solution to intermittency in renewable energy generation.

What are the performance parameters of energy storage capacity?

Our findings show that energy storage capacity cost and discharge efficiency are the most important performance parameters. Charge/discharge capacity cost and charge efficiency play secondary roles. Energy capacity costs must be ≤US$20 kWh –1 to reduce electricity costs by ≥10%.

Can energy capacity and discharge power capacity be varied independently?

In our exploration of the LDES design space it was assumed that the three scaling dimensions, that is, energy capacity, discharge power capacity and charge power capacity, can be varied independently, even though all three degrees of freedom are not possible for certain technologies.

Do nanostructured storage devices increase capacitance density?

Nanostructured storage devices with 3D metal–insulator–metal (MIM) architectures—which require conformal metal and insulator deposition inside porous nanostructures—have successfully increased capacitance density, and therefore energy storage, per unit planar area (Fig. 3b, Supplementary Table 3).
