Supercapacitors: the economics?
Costs of supercapacitors storing 15-seconds of electricity average $10,000/kWh, but just $40/kW in power terms. Economics are in
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.
While lithium-ion batteries dominate headlines, supercapacitor cost per kWh has emerged as a critical metric for industries demanding rapid charge-discharge cycles and extreme durability. In 2023, the average supercapacitor energy storage system ranged between $3,000-$5,000 per kWh – significantly higher than traditional batteries.
Supercapacitor applications in the bulk-power systems: (a) a schematic of a volt/VAR control using a static compensator with supercapacitors, and (b) a schematic of renewable energy regulation using a supercapacitor bank. Adapted from, .
A primary application is in consumer electronic devices where they have a wide range of uses, including filtering signals and storing small amounts of energy for power backup. Advances in supercapacitor materials, construction, and manufacturing techniques improved the performance of supercapacitors.
