View more6 FAQs about [Large-capacity and long-term energy storage technology case]
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.
Are energy storage systems a long-term solution?
Lack of viable solutions to store excess electricity may force some utility companies to curtail this excess energy and lose the cost incurred in the production of this energy. Thus, ESSs represent a long-term solution to increase the resiliency of power grids and to allow for higher percentages of renewables in the power mix in the future.
Why are large-scale energy storage technologies important?
Learn more. The rapid evolution of renewable energy sources and the increasing demand for sustainable power systems have necessitated the development of efficient and reliable large-scale energy storage technologies.
Which storage technologies are dominated by energy-capacity costs?
For comparison, short-duration storage technologies dominated by energy-capacity costs include flywheels, capacitors, and Li-ion and lead-acid batteries. Separating power and energy costs is more difficult for batteries.
Could long-term storage technology improve the affordability of renewable electricity?
Innovation in long-term storage technology could further improve the affordability of reliable renewable electricity. Reliable and affordable electricity systems based on variable energy sources, such as wind and solar may depend on the ability to store large quantities of low-cost energy over long timescales.
Can energy storage technology help a grid with more renewable power?
Energy storage technologies with longer durations of 10 to 100 h could enable a grid with more renewable power, if the appropriate cost structure and performance—capital costs for power and energy, round-trip efficiency, self-discharge, etc.—can be realized.
