This report provides insight and market intelligence into the market for supercapacitors including three supercapacitor types (electric double-layer supercapacitors, pseudo-capacitors and hybrid supercapacitors). The forecast covers a ten-year period from 2026-2036, and forms the most comprehensive market analysis to date on supercapacitors, covering seven market segments, including automotive/transport, power grid and uninterruptible power supply (UPS). Example products and player analysis are also included.
 
Supercapacitor types
The report recognizes three broad categories of supercapacitors/ultracapacitors, which are distinguished both by their charge storage mechanisms and their electrochemical properties:
  • Electric double-layer supercapacitors (EDLSs) are the most common supercapacitor type and the most mature technology. They offer high power density and cycle life at a low cost, but cannot compete in terms of energy density.
  • Pseudocapacitors offer a more moderate energy density with lower power density and cycle life, but are in the early stages of development, with few products close to commercialization.
  • Hybrid supercapacitors offer moderate power density and cycle life and higher energy density but at a high cost, which is expected to decrease as more products are commercialized and economy of scale is achieved.
 
The niche for supercapacitors
Supercapacitors act as an interim between batteries and capacitors. They are unable to provide the extremely high power density of capacitors or the higher energy density of a lithium-ion battery, however they offer reasonably high power density and low-moderate energy density, which makes them suitable for a variety of niche applications. Supercapacitors can achieve a low cost/W but the cost/Wh is usually an order of magnitude greater than that of lithium-ion batteries.
 
The niche for supercapacitors is for applications requiring high power density and cycle life but higher energy density than conventional capacitor technologies are able to achieve.

Supercapacitor applications
In the past, automotive/transport applications dominated the market for supercapacitors, specifically regenerative braking, start-stop systems, and for use in electric trains and trams. However, power grid applications for frequency response in renewable energy systems are expected to grow to be a more significant part of the market by 2036, as is explored in more detail in the report.
 
Other emerging applications in materials handling and intralogistics and for uninterruptible power supply in data centers and semiconductor manufacturing are expected to also be significant portions of the market over the next decade, though they are limited by the total power demand of these industries.
