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.
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.
Moreover, the researchers conclude that energy storage capacity cost and discharge efficiency are the most critical drivers for the cost-effectiveness of long-duration storage technologies — for example, energy capacity cost becomes the largest cost driver as discharge duration increases.
Energy storage duration is typically expressed in terms of the number of hours a storage device can provide continuous output at its rated capacity. Definitions of LDES in the literature range from as little as 2 hours to as much as multiple days or even months.
This range reflects how different studies of energy storage often consider different aspects, including different technologies (e.g., a battery with 4 hours of capacity, which has longer duration than most currently deployed) or different grid scenarios (e.g., a study of a future grid with very different required attributes than today’s).
The duration of a battery is the length of time that a storage system can sustain power output at its maximum discharge rate, typically expressed in hours. The energy capacity of the battery storage system is defined as the total amount of energy that can be stored or discharged by the battery storage system.
