In the transportation sector, the increasing demand for electric vehicles (EVs) and hybrid electric vehicles (HEVs) has largely boosted sales of regenerative braking and peak-power solutions. Supercapacitors play a critical role by absorbing high-current pulses during braking and providing the necessary bursts of power during acceleration, which helps extend the lifespan of on-board batteries. Unlike lithium-ion batteries, which store energy via slow chemical reactions, supercapacitors store energy through the physical movement of ions, enabling nearly instantaneous charge and discharge cycles.

Grid modernization is an important growth factor for the market. The growing integration of intermittent renewable energy resources, such as wind and solar, has increased grid instability, along with requiring response times of milliseconds for stabilizing frequency and providing voltage support. Supercapacitors are uniquely capable of providing "firming" in these applications by supplying short-duration power when necessary, until slower-responding assets such as gas turbines or long-duration batteries can engage. This fast-response capability is becoming essential for the resilience of smart energy infrastructure. Additionally, Asia-Pacific continues to lead adoption due to its strong electronics manufacturing base and proactive government support for new energy vehicles. Meanwhile, North America and Europe are both experiencing rapid growth in their grid-scale and industrial automation markets, benefiting from infrastructure investment programs and green deal frameworks.
