Flue Gas Desulfurization System Market Report 2026

The flue gas desulfurization system market size has grown strongly in recent years. It will grow from $21.46 billion in 2025 to $22.71 billion in 2026 at a compound annual growth rate (CAGR) of 5.9%. The growth in the historic period can be attributed to expansion of coal-based power generation, tightening air pollution regulations, growth in heavy industrial activity, increasing awareness of emission control technologies, availability of large-scale fgd solutions.

The flue gas desulfurization system market size is expected to see strong growth in the next few years. It will grow to $28.55 billion in 2030 at a compound annual growth rate (CAGR) of 5.9%. The growth in the forecast period can be attributed to increasing investments in clean energy transition, rising demand for low-emission industrial operations, expansion of brownfield plant upgrades, growing adoption of digital monitoring systems, increasing global environmental compliance standards. Major trends in the forecast period include increasing deployment of wet and semi-dry fgd systems, rising demand for high-efficiency so2 removal, growing retrofitting of existing industrial plants, expansion of automated emission control systems, enhanced focus on regulatory compliance.

The rise in air pollution is expected to drive the growth of the flue gas desulfurization system market in the future. Air pollution is characterized by the presence of harmful substances or pollutants in the Earth's atmosphere, which can adversely affect the environment, human health, and the well-being of other living organisms. Flue gas desulfurization (FGD) systems are essential for combating air pollution by reducing sulfur dioxide (SO2) emissions from industrial sources, especially coal-fired power plants. These systems utilize various technologies to capture and eliminate sulfur dioxide from flue gases before they are released into the atmosphere. In doing so, FGD systems help prevent acid rain formation, mitigate respiratory problems linked to SO2 exposure, and comply with strict environmental regulations aimed at decreasing harmful emissions. For example, in June 2023, the World Health Organization, a specialized agency of the United Nations based in Switzerland, published an article stating that air pollution represents a significant threat to health and climate, with approximately 2.4 billion people exposed to dangerous levels of household air pollution, which is responsible for 7 million premature deaths annually. Thus, the increase in air pollution is propelling the flue gas desulfurization system market.

The growing number of coal-fired power plants is anticipated to drive the expansion of the flue gas desulfurization system market in the coming years. Coal-fired power plants are facilities that generate electricity by combusting coal. This increase in coal-fired power plants is driven by rising global energy demand and continued dependence on coal as a primary energy source. Flue gas desulfurization systems reduce sulfur dioxide and other harmful emissions from these power plants, ensuring adherence to environmental regulations and improving air quality. For example, in 2024, the International Energy Agency (IEA), a France-based intergovernmental energy agency, reported coal production reaching a record 9.15 billion tonnes and projected a slight increase to 9.2 billion tonnes in 2025. Consequently, the rise in coal-fired power plants is fueling growth in the flue gas desulfurization system market.
