Just for comparison, the energy density of the pumped hydro storage is 0.2—2 Wh/kg, which is rather low and requires significant masses of water and large reservoir size to deliver utility scale power. Power density (measured in W/kg or W/liter) indicates how quickly a particular storage system can release power.
Power density (measured in W/kg or W/liter) indicates how quickly a particular storage system can release power. Storage devices with higher power density can power bigger loads and appliances without going oversize. Imagine an electric vehicle accelerating from 0 to 60 MPH – which takes a lot of power.
Energy density is often used to compare different energy storage technologies. This parameter relates the storage capacity to the size or the mass of the system, essentially showing how much energy (Wh) can be stored per unit cell, unit mass (kg), or unit volume (liter) of the material or device.
Here are some round-trip efficiencies of various energy storage systems: These numbers mean the following. For example, out of 1 MWh of energy spent to pump water up to the hydro storage, only 0.7-0.8 MWh will be available to use after the water is released to run the turbine and generator to produce electric power.
For this application, high-power energy storage devices with sophisticated power electronics interfaces—such as SMES, supercapacitors, flywheels, and high-power batteries—have become competitive options. These storage devices can sense disturbances, react at full power in 20 ms, and inject or absorb oscillatory power for a maximum of 20 cycles.
Energy density is related to capacity and determines the duration of power generation. Also materials with higher energy density help make the power block more compact, which is useful in portable electronics and vehicle applications.
