6 FAQs about [Energy storage discharge cost]

What is charge/discharge capacity cost & charge efficiency?

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%. With current electricity demand profiles, energy capacity costs must be ≤US$1 kWh–1 to fully displace all modelled firm low-carbon generation technologies.

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%.

Does discharge duration affect unit power costs?

Technologies with independent power and energy costs and low energy costs, like CAES, are only marginally impacted in terms of unit power costs by changes in discharge duration.

Why is discharged electricity more expensive than pure electricity?

For all technologies which use only electricity in the discharging process (as opposed to dCAES systems, which use also gas), the cost of discharged electricity is therefore higher than the cost of pure electricity storage plus the cost of charged electricity. The overall efficiency of the plant needs to be taken into account as well.

What factors affect energy storage cost?

Operation and cost of electricity purchase have a high influence on storage cost. The ratio of charging/discharging unit power and storage capacity is important. PSH and CAES are low-cost technologies for short-term energy storage. PtG technologies will be more cost efficient for long-term energy storage.

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).
