Supercapacitors: the economics?
The costs of supercapacitors are tabulated in this data-file, with a typical system storing 15-seconds of electricity, for a capex cost around $10,000/kWh of energy but just
In 2023, the average supercapacitor energy storage system ranged between $3,000-$5,000 per kWh – significantly higher than traditional batteries. But why does this gap exist, and when will it close? Unlike batteries that rely on chemical reactions, supercapacitors store energy electrostatically.
The capex costs of supercapacitors are contrasted with the costs of lithium ion batteries and the costs of flywheels in the chart below. A typical supercapacitor stores about 15 seconds of energy, for a capex cost of $10,000/kWh, but just $40/kW of power.
