MARKET DYNAMICS

Market Drivers

Increasing Adoption of Automotive Electrification Setting Leads to Market Growth

The global move toward the electrification of transportation is driving the supercapacitors market growth. As the automotive industry transitions from conventional internal combustion engines to hybrid and electric vehicles, the need for energy storage systems that can deliver rapid bursts of power and withstand frequent charge and discharge cycles has intensified. For instance,

• In April 2025, BMW filed a patent for a supercapacitors-hybrid system aimed at motorsport vehicles, capable of charging in just one minute (potentially 30 seconds). With over 20 kWh capacity, it rapidly stores energy, including kinetic energy recovery and supplements traditional batteries.

In modern vehicles, particularly those adopting 48-volt mild-hybrid architectures, supercaps play an essential role in supporting energy-demanding functions such as regenerative braking, acceleration assistance, and start-stop mechanisms. For instance, In October 2022, Belgrade began testing Europe’s first 18 m ultracapacitor electric bus by Chariot Motors, featuring 108 kWh ultracapacitors that reuse braking energy through recuperation. This technology enables the bus to recharge in minutes and operate efficiently on urban routes, marking a major step toward sustainable city transport.

• In June 2025, Allotrope Energy (U.K.) developed supercaps using sustainable Lignavolt material that deliver twice the energy density of traditional supercaps (14–15 Wh/kg) at lower cost. Ideal for hybrid powertrains, they efficiently capture energy from regenerative braking, provide rapid electrical assistance, and reduce reliance on large combustion engines.

Market Restraints

Application Specific Suitability of Supercapacitors to Suppress the Market Share

A major restraint affecting the market growth is its limited application suitability. Supercaps have distinctive strengths such as high power density, rapid charging and discharging capability, and long operational life. These qualities make them valuable for specific applications that require quick energy delivery or frequent charge cycles. However, it also limits their use in situations that demand long duration energy storage or a steady power supply over time.

Supercaps perform exceptionally well in applications such as regenerative braking in electric vehicles, short term backup systems, and voltage stabilization in power grids. In such cases, their capability to release energy almost instantly and recharge within seconds provides a clear operational benefit.

Nevertheless, in applications where continuous power is essential, such as electric vehicles requiring extended range or renewable energy systems that store power for long periods, supercaps are less effective. Their energy storage capacity is considerably lower than that of batteries, which restricts their usefulness in these long duration tasks.

Market Opportunities

Integration with Renewable Energy and Grid Systems to Create Opportunities for Market

The increasing global shift toward renewable energy sources such as solar and wind is creating promising opportunities for the use of supercaps in modern power systems. Renewable energy generation is naturally intermittent, with power output fluctuating due to changes in sunlight and wind conditions. These variations can make it difficult to maintain a consistent and reliable energy supply.

Supercaps provide efficient energy storage by delivering rapid bursts of power and handling frequent charge-discharge cycles with minimal degradation. Their ability to absorb and release energy instantly makes them ideal for stabilizing power systems, balancing supply and demand, and supporting peak load requirements. For instance,

• In April 2025, Researchers from DGIST and Kyungpook National University developed a self-charging solar supercaps that can store 63% of captured solar energy, offering a faster and more efficient alternative to traditional batteries. The device combines silicon solar cells with nickel-based electrodes improved by metal ions (such as cobalt and manganese) to improve conductivity and durability.
