New research puts the global supercapacitor market at $5.46 billion in 2025, projecting it to reach $55.51 billion by 2035. That is a 26% annual growth rate. The demand is splitting into two main areas. First is heavy industrial and transport. Komatsu is using hybrid capacitor systems in excavators which apparently cut fuel consumption by 40%. The rail sector is also using them for handling peak power loads. The second driver is retail automation. Walmart and Carrefour are adopting electronic shelf labels that use low-capacitance units. This segment actually holds about 45% of the market share right now. Supply chain is still tight. Raw material scarcity caused a 20% price hike in carbon materials last July. Companies like Eaton, Tesla, and Murata are listed as major players adapting to these shifts.
