6 FAQs about [Variable capacity energy storage]
What is long-term energy storage?
Long-term, large-capacity energy storage may ease reliability and affordability challenges of systems based on these naturally variable generation resources. Long-duration storage technologies (10 h or greater) have very different cost structures compared with Li-ion battery storage.
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%.
Are variable renewable power systems more sensitive to long-duration storage costs?
Indeed, we find that variable renewable power systems are much more sensitive to reductions in long-duration storage costs than to equal reductions in battery costs.
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.
How is energy and power capacity optimized in a candidate storage plant?
Energy and power capacity of candidate storage plants are unconstrained and optimized by the model from the perspective of the grid, such that the model may build storage of any duration and size in each load zone.
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.
