All battery-based energy storage systems degrade over time, leading to a loss of capacity. As the energy storage industry grows, it’s critical that project developers proactively plan for this inevitable ‘degradation curve’.
Capacity loss can be defined as an irreversible loss of the ability of the battery to store charge . A higher internal resistance reduces the efficiency of the cell, which leads to less usable energy being available and more heat being generated.
The impact of operating strategy and temperature in different grid applications Degradation of an existing battery energy storage system (7.2 MW/7.12 MWh) modelled. Large spatial temperature gradients lead to differences in battery pack degradation. Day-ahead and intraday market applications result in fast battery degradation.
The energy storage of a battery can be divided into three sections known as the available energy that can instantly be retrieved, the empty zone that can be refilled, and the unusable part, or rock content, that has become inactive as part of use and aging. Figure 1 illustrates these three sections.
Battery degradation manifests in two measurable effects: a diminished ability to store energy and increased internal resistance.
Another study from ‘Fraunhofer’ predicts that the installed battery capacity has to be increased up to 400 GWh in a worst-case scenario . Here, the storage capacity has to be eight times higher, since the consumers are not willing to change their behaviour. Therefore, more energy has to be time-shifted.
