Increasing renewable energy system value through storage

Intermittent renewable energy sources do not always provide power at times of greatest electricity demand or highest prices. To do so reliably, energy storage is likely required. However, no single energy storage technology is dominant when comparing cost intensities of the energy capacity and power capacity of storage. Past research on energy storage technologies has debated the value of storage technologies for different applications, and has compared the cost structures of different storage technologies without finding generalizable results across both locations and technologies. Here, a single performance metric, the benefit / cost ratio (X) of storage value added is analyzed across six locations globally to show that the relative value of storage technologies is largely location invariant. Electricity price dynamics, specifically the frequency and height of price spikes determine the value of storage, while the duration of price spikes determines the relative value of one technology versus another. We find that cost targets can be set for different technologies with ranging energy and power costs of storage.
