Are supercapacitors energy storage devices?

The price per unit of energy (kWh) is extremely high. Energy accumulation and storage is one of the most important topics in our times. This paper presents the topic of supercapacitors (SC) as energy storage devices. Supercapacitors represent the alternative to common electrochemical batteries, mainly to widely spread lithium-ion batteries.

What is the capacity of a supercapacitor?

The capacity of the supercapacitor in (b) is 24 MW. The intervention of the supercapacitors reduces the battery''s SOC bounce. However, since the size of a supercapacitor is small, it absorbs only a tiny variation in the BESS SOC. Therefore, since the variation width of the BESS SOC is reduced, the wear cost is also reduced.
