Waste Heat Recovery System Market

The waste heat recovery system market is projected to reach USD 135.33 billion in 2031 from USD 92.99 billion in 2026, at a CAGR of 7.8%. The global waste heat recovery system market is rapidly evolving, driven by extensive industrial energy waste, strict carbon reduction mandates, soaring grid power prices, and rising low-temperature thermodynamic activities. While high initial capital investments and complex site retrofitting qualification requirements present market restraints, massive expansion in heavy industrial decarbonization, modular organic rankine cycle (ORC) scaling, and hyperscale data center heat integration offer significant opportunities. Manufacturers must navigate challenges such as fractured regional environmental mandates and tight cost-to-benefit ratios.

The waste heat recovery system market is dominated by major players such as Siemens Energy AG (Germany), GE Vernova Inc. (US), Mitsubishi Heavy Industries, Ltd. (Japan), ABB Ltd. (Switzerland), and Shanghai Electric Group Co., Ltd. (China). Companies are strengthening their presence in the global waste heat recovery system market by pursuing product launches, strategic partnerships, collaborations, joint ventures, and targeted acquisitions. For example, Mitsubishi Heavy Industries Thermal Systems recently expanded its portfolio by launching the "ETI-W" centrifugal heat pump to capture industrial wastewater heat, while GE Vernova continues to deploy its large-scale Heat Recovery Steam Generator (HRSG) technologies in major combined-cycle modernization projects.
