The market involves technologies and systems used to remove sulfur dioxide (SO₂) from industrial emissions, primarily in coal-fired power plants and heavy industries. These systems reduce air pollution, prevent acid rain, and support regulatory compliance and sustainable operations. The report outlines the primary drivers of market growth, along with an in-depth analysis of emerging trends and evolving regulatory frameworks shaping the industry's trajectory.
The global flue gas desulfurization market size was valued at USD 22.45 billion in 2024 and is projected to grow from USD 23.09 billion in 2025 to USD 28.45 billion by 2032, exhibiting a CAGR of 2.98% during the forecast period.
This growth is propelled by regulatory support, financial incentives, and stricter SO₂ norms, promoting adoption in thermal plants and cement industries. Wet limestone scrubbers enable these sectors to meet emission targets and sustainability goals while reducing import dependence.
Major companies operating in the flue gas desulfurization industry are MITSUBISHI HEAVY INDUSTRIES, LTD., GE Vernova, ANDRITZ, Babcock & Wilcox Enterprises, Inc., RAFAKO S.A., MET, Thermax Limited., DUCON, Chiyoda Corporation, Valmet, Kawasaki Heavy Industries, Ltd., Macrotek Inc., AECOM, Steinmüller Engineering GmbH, and Carmeuse Americas.
The market is witnessing strong growth due to the increasing reliance on coal-fired power generation in developing countries. As coal remains a primary energy source, particularly in rapidly industrializing nations, the associated rise in sulfur dioxide emissions has prompted the need for effective emission control technologies.
With low compliance rates and rising environmental concerns, governments are enforcing stricter regulations, boosting demand for FGD systems to mitigate air pollution and meet sustainability targets.
Key Highlights:Market Driver
Government Support and Incentives for Pollution Control Technologies
The expansion of the flue gas desulfurization market is fueled by strong government support and financial incentives for pollution control technologies. With mandatory SO₂ emission norms and penalties for non-compliance, authorities are promoting FGD adoption through regulatory deadlines and support for domestic manufacturing .
These policy measures are driving demand, reducing import dependence, and accelerating installation in thermal power plants, creating a favorable environment for market growth amid rising pressure to meet emission targets efficiently and promptly.
Market Challenge
High Energy Consumption of FGD System Operations in Power Plants
The high energy consumption of flue gas desulfurization (FGD) systems poses a major challenge, particularly in coal-fired power plants where operational efficiency is critical. FGD units require significant electricity to operate pumps, fans, and other components, increasing the overall auxiliary power load. This reduces net power output and raises operating costs, thereby impacting economic performance.
The added energy demand also strains older power infrastructure, complicating retrofitting efforts. To address this challenges, companies are developing low-energy FGD designs, optimizing system configurations, and integrating smart monitoring technologies to improve efficiency. Some are also exploring hybrid systems to reduce energy consumption.
Market Trend
Surging Adoption in Cement Industry
Flue gas desulfurization market is witnessing a notable trend toward the increasing adoption in the cement industry as emission regulations extend beyond power generation. Cement plants, which emit significant sulfur oxides during production, are integrating FGD systems to meet tightening environmental norms.
The use of wet limestone scrubbers with gypsum by-product aligns with industrial sustainability goals. This trend reflects broader cross-sectoral uptake of FGD technologies to reduce air pollution and comply with national emission standards, particularly in high-emission industries such as cement.
