6 FAQs about [Capacitor energy storage cost per kilowatt-hour]

Why are supercapacitors more expensive than batteries?

High capital cost and low energy density of supercapacitors make the unit cost of energy stored (kWh) more expensive than alternatives such as batteries. Their attributes make them attractive for uses in which frequent small charges/discharges are required (e.g., ensuring power quality or providing frequency regulation).

How is charge stored in a capacitor?

Charge is stored by electrostatic attraction between positive and negative charges, however the opposite charges are held in very close proximity to where the electrolyte meets the electrode. A charged capacitor or supercapacitor electrode will have an excess of either electrons, or holes (missing electrons).
