The 2022 Cost and Performance Assessment analyzes storage system at additional 24- and 100-hour durations. In September 2021, DOE launched the Long-Duration Storage Shot which aims to reduce costs by 90% in storage systems that deliver over 10 hours of duration within one decade. The analysis of longer duration storage systems supports this effort.

5.6. Durability (cycling capacity) This refers to the number of times the storage unit can release the energy level it was designed for after each recharge, expressed as the maximum number of cycles N (one cycle corresponds to one charge and one discharge). All storage systems are subject to fatigue or wear by usage.

The benefit of proposed operating strategy is that PHS will come in operation only when absolute power deficiency is higher, thus it will work as peak power shaving. As the power density and response time of battery bank is higher than PHS (as presented in Table 1), it is obvious that battery bank can easily and rapidly deal with the inferior power …
