Supercapacitor Market Size, Growth & Industry Trends | 2025
The U.S. Department of Energy projects levelized storage costs of USD 0.337 per kWh by 2030 as automated cell production scales. Operators also cite environmental
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.
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.
Despite higher upfront costs ($3,000–$5,000 per kWh for super-capacitors vs. $150–$200 per kWh for lithium batteries), total cost of ownership is becoming a decisive factor. A 2024 analysis by IDTechEx found that hybrid battery-super-capacitor systems in EVs lowered replacement costs by 60% over 10 years.
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).
