Energy Storage Systems
Overview of short, medium, and long-duration storage needs.
Duration vs Capacity
While Li-ion wins short duration (1-4 hours), Long Duration Energy Storage (LDES) technologies like compressed air (CAES), flow batteries, and thermal storage are required to bridge multi-day weather events where wind and solar underperform.

Frequently Asked Questions
What is the difference between power and capacity?
Power (measured in MW) is how fast energy can be delivered. Capacity (measured in MWh) is the total volume of energy stored. A 100 MW / 400 MWh battery can discharge 100 MW continuously for 4 hours.
