Learn MoreEnergy 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.
While the term long-duration energy storage (LDES) is often used for storage technologies with a power-to-energy ratio between 10 and 100 h, 1 we introduce the term ultra-long-duration energy storage (ULDES) for storage that can cover durations longer than 100 h (4 days) and thus act like a firm resource.
True resiliency will ultimately require long-term energy storage solutions. While short-duration energy storage (SDES) systems can discharge energy for up to 10 hours, long-duration energy storage (LDES) systems are capable of discharging energy for 10 hours or longer at their rated power output.
However, if wind and solar penetration rises to cover all demand in the absence of other generation technologies, longer duration energy storage becomes necessary to supply multiple days or weeks of dark wind lulls and seasonal variations in supply and demand, as well as to bridge years of low renewable production.
An energy storage system capable of serving long durations could be used for short durations, too. Recharging after a short usage period could ultimately affect the number of full cycles before performance declines. Likewise, keeping a longer-duration system at a full charge may not make sense.
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.
