The global market for fuel gas systems in combined-cycle power plants is expected to grow significantly, reaching $1,837.7 million by 2031. This represents a steady increase from $1,410.2 million in 2026, with a compound annual growth rate (CAGR) of 5.4% during the forecast period. The market is driven by the rising demand for reliable fuel delivery, gas-quality management, and safe gas turbine operation, particularly as natural gas supply streams become more complex and fuel-quality requirements become stricter.
The adoption of hydrogen-natural gas blends is also creating new technical requirements for fuel gas systems, leading to advancements in skid design, instrumentation, control systems, and gas-quality monitoring. These innovations are supporting the development of more flexible and application-specific fuel gas solutions for combined-cycle gas turbine (CCGT) power plants.
Asia Pacific is expected to lead the market, with a CAGR of 5.8%, supported by investments in industrial automation, electrification, and power infrastructure. The above-600 MW segment is projected to register the highest CAGR of 5.9%, driven by the development of large-capacity CCGT plants and the need for high-volume, reliable fuel-gas supply systems.
Utilities are expected to maintain their leading position in the market, supported by investments in new CCGT projects and the modernization of existing power-generation facilities. North America is anticipated to be the fastest-growing region, with strong investment in new combined-cycle power generation and increasing electricity demand.
