Energy storage in-depth analysis huijue

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%.

What is the optimal storage discharge duration?

Finally, in cases with the greatest displacement of firm generation and the greatest system cost declines due to LDES, optimal storage discharge durations fall between 100 and 650 h (~4−27 d).

How does energy capacity cost affect LDEs value?

These figures indicate that reductions in energy capacity cost (columns going from right to left) are the most crucial driver of LDES value, followed by increases in RTE (y axis from bottom to top in each subplot), followed by reductions in weighted power capacity cost (x axis going from right to left in each subplot).
