Key Trends in the Heat Recovery Steam Generator Market

• Growing Energy Efficiency Concerns Across Industries: The need to reduce energy consumption and minimize environmental impact is becoming a top priority for businesses across sectors including chemicals, refineries, and pulp and paper. HRSG systems capture and reuse waste heat generated during industrial processes or power generation, helping companies reduce their carbon footprint and cut operational costs simultaneously. Utilities and industrial operators are increasingly integrating digital monitoring systems and automated thermal optimization technologies to improve steam recovery efficiency and reduce industrial emissions on a global scale.
  
  
  
• Expanding Adoption in Combined Cycle Power Plants: Governments worldwide are encouraging the transition to cleaner energy alternatives, making combined cycle gas turbine plants equipped with HRSG systems increasingly attractive. These integrated setups significantly boost the overall efficiency of electricity generation by converting exhaust gas heat into additional steam-driven power output. Growing investments in refinery modernization and industrial cogeneration facilities are further accelerating the deployment of advanced steam recovery and thermal monitoring technologies through 2025 and 2026.
  
  
  
• Hydrogen-Ready HRSG Technology Gaining Traction: Manufacturers are certifying HRSG designs for hydrogen-blended and full-hydrogen fuel operation, positioning them as strategic assets in the long-term decarbonization of power generation. John Cockerill's HRSG system received TUV SUD certification as hydrogen-ready, making it one of only two manufacturers globally to receive this recognition, covering both drum-type and once-through boiler designs for combined cycle and cogeneration applications. This enables power plants to operate on natural gas today while retaining a clear pathway to zero-emission hydrogen-based generation in the future.
  
  
  
• Industrial Expansion and Infrastructure Development Driving Demand: As economies grow and urbanization continues, the demand for reliable power generation solutions is escalating across industries including oil and gas, chemicals, and manufacturing. HRSG systems are being used for steam generation and energy recovery in these sectors, reducing energy costs while ensuring more sustainable and eco-friendly plant operations. The construction of gas-fired power stations, refinery modernization projects, and cogeneration plants is expected to sustain strong demand for HRSG installations well into the near term.
  
  
  
• Modular and Compact HRSG Designs Gaining Market Traction: Modular construction is expected to account for approximately 41% of the design type segment, driven by operational efficiency requirements and cost optimization. Compact modular HRSG systems are finding increasing application in decentralized power generation projects and district heating infrastructure, particularly in locations where space is at a premium such as marine, offshore, and urban environments. This shift is allowing operators to deploy energy recovery systems faster while maintaining flexibility and scalability.
