The forecast puts the market at $3.69 billion in 2026, with Asia Pacific holding the largest regional share and fuel cells identified as the fastest-growing prime mover segment.
MarketsandMarkets said the global micro combined heat and power market is projected to grow from USD 3.69 billion in 2026 to USD 5.77 billion by 2031, reflecting a 9.3% CAGR over the forecast period. The firm said demand is being driven by a shift toward decentralized and energy-efficient power generation, stronger focus on carbon-emissions reduction, and the need for greater energy security and grid resilience. Micro CHP systems generate electricity and useful heat from a single fuel source, which can improve overall efficiency and lower operating costs for residential and small commercial users. Asia Pacific is expected to remain the largest regional market, supported by adoption in Japan and broader energy-efficiency and carbon-reduction efforts across China and South Korea. By segment, the 11-50 kW category leads by capacity, internal combustion engines are identified as the fastest-growing technology, and fuel cells are expected to be the fastest-growing prime mover during 2026-2031. MarketsandMarkets named Viessmann, YANMAR HOLDINGS CO., LTD, Bosch Industriekessel GmbH, BDR Thermea Group, and AISIN CORPORATION among key companies.
