Flue Gas Desulfurization (FGD) System Market: Global Forecast to 2031 | Tougher Sulfur Rules Keep Flue-Gas Scrubbers in Demand as Energy Transition Looms

The global flue gas desulfurization system market is projected to grow from $23.6 billion in 2026 to $31.7 billion by 2031, with a CAGR of 6.1%. Growth is driven by stringent SO2 emission regulations, retrofit programs for aging coal plants, and continued coal reliance in developing economies. Dry & semi-dry FGD systems are expected to record the highest growth, while power generation remains the leading end-use industry. Europe is positioned as the second-largest regional market.
