Heat Recovery Steam Generator Market Size - Share Outlook, Growth Analysis Report and Forecast Trends 2026-2030

HRSGs are essential components in combined-cycle power plants, where they recover waste heat from gas turbine exhaust to produce steam that drives additional turbines or supplies industrial processes. This technology significantly boosts overall plant efficiency, often raising it from around 35 percent to over 60 percent by utilizing energy that would otherwise be lost. The technology is deployed across a wide range of applications, from large utility-scale power generation to industrial facilities in refining, chemicals, and manufacturing. With an estimated market value of $1.91 billion in 2025, the market reflects a balance between traditional fossil-fuel power generation needs and broader energy efficiency goals.

• •Estimated global market size of $1.91 billion in 2025, with steady projected growth through the early 2030s supported by new installations and retrofit demand
• •Combined-cycle power plants represent the primary application segment, where HRSGs are integral to achieving high thermal efficiency
• •Industrial sectors including petrochemical refining, chemicals, and manufacturing also rely on HRSGs for waste heat recovery and process steam generation

The market is being propelled by the global demand for more efficient and flexible power generation, as combined-cycle plants equipped with HRSGs offer compelling efficiency advantages over conventional thermal plants. Natural gas continues to serve as a key transitional fuel, with many new power projects incorporating HRSGs to maximize output while managing emissions. Industrial operators are also investing in HRSGs to reduce energy costs and improve process efficiency, particularly in energy-intensive sectors such as refining and chemicals. Government policies promoting energy efficiency and stricter emissions regulations further incentivize HRSG adoption in both new builds and retrofit applications.

• •Growing natural gas-fired power generation capacity globally, as HRSGs are integral to achieving the high efficiencies associated with combined-cycle plants
• •Industrial demand for waste heat recovery to reduce fuel consumption, lower operating costs, and meet emissions targets in refineries, chemical plants, and manufacturing facilities
• •Regulatory frameworks promoting energy efficiency and carbon reduction encourage HRSG deployments in both new and existing power and industrial plants

The market is segmented by HRSG type into natural circulation and forced circulation units, with natural circulation designs dominating large-scale applications due to their proven reliability and lower maintenance requirements. By configuration, drum-type HRSGs remain widely used, though once-through designs are gaining traction for certain operational flexibility needs. Regionally, North America and Europe represent mature markets with steady replacement demand and upgrades to aging fleets, while Asia-Pacific is the fastest-growing region driven by expanding power infrastructure and industrialization. The United States alone represented one of the largest national markets, with estimates around $780 million in 2025, reflecting sustained investment in combined-cycle gas turbine plants.

• •Asia-Pacific is the fastest-growing regional market, supported by expanding energy infrastructure in countries including China, India, and throughout Southeast Asia
• •North America, particularly the United States, remains a major market due to extensive existing power plant infrastructure and ongoing investment in efficient natural gas generation
• •The market spans utility-scale power generation, industrial process applications, and district heating and cogeneration systems, each with distinct technical and economic requirements

What are the recent trends and outlook?

The HRSG market is expected to benefit from the continued deployment of combined-cycle gas turbine plants as a flexible complement to intermittent renewable energy sources such as wind and solar, helping to stabilize grids during periods of low renewable output. Advances in HRSG design, including improved materials and optimized configurations, are enabling higher thermal efficiencies and longer operational lifetimes, while new designs are being developed to accommodate hydrogen and low-carbon fuels. The aftermarket segment for HRSG upgrades, retrofits, and maintenance services represents a growing opportunity as operators seek to extend the life and efficiency of existing installations. While the long-term energy transition toward renewables poses structural challenges, HRSGs are likely to remain relevant for decades, particularly in regions with established natural gas infrastructure.

• •HRSG designs are being adapted for hydrogen and low-carbon fuel combustion, positioning the technology for a role in future low-carbon power systems
• •The market is expected to grow to approximately $2.45-2.65 billion by 2030-2032, with the pace of growth influenced by regional energy policies and natural gas demand trends
• •Repowering and upgrading existing HRSG installations to improve efficiency and extend operational life represents a significant and expanding aftermarket opportunity
