The ''storage duration'' rating indicates the relationship between the storage capacity and the nominal power rating of the energy store, not the actual amount of time that energy is stored before being used. Fig. 8, Fig. 13 have shown that long-duration or ''seasonal'' storage will be needed to decarbonize the grid. The need for long

Consider a power bank with an energy content of 37 Wh and a capacity of 10 Ah. Compared to the residential battery System A with a capacity six times as large, the energy content of the power bank is as much as 264 times smaller. This is due to the difference in internal voltage, as the power bank battery voltage is only 3.7 V.

The math is simple: Energy (Watt-hours) = Capacity (amp-hours) x Voltage (volts) Let''s look at an example using the equation above — if a battery has a capacity of 3 amp-hours and an average voltage of 3.7 volts, the total energy stored in that battery is 11.1 watt-hours — 3 amp-hours (capacity) x 3.7 volts (voltage) = 11.1 watt
