Wet Flue Gas Desulfurization System Market Report 2025

The wet flue gas desulfurization system market size has grown strongly in recent years. It will grow from $17.47 billion in 2024 to $18.38 billion in 2025 at a compound annual growth rate (CAGR) of 5.2%. The growth in the historic period can be attributed to stringent environmental regulations, increasing coal-fired power plants, government subsidies for pollution control, the high sulfur content of coal, and rising health concerns.

The wet flue gas desulfurization system market size is expected to see strong growth in the next few years. It will grow to $23.35 billion in 2029 at a compound annual growth rate (CAGR) of 6.2%. The growth in the forecast period can be attributed to the transition to renewable energy sources, rising costs of installation and maintenance, regulatory relaxations in some regions, increasing natural gas use, and demand for compact and efficient systems. Major trends in the forecast period include integration with carbon capture systems, a focus on energy-efficient systems, the development of hybrid systems, innovation in sorbent materials, and the adoption of digital monitoring solutions.

The forecast of 6.2% growth over the next five years reflects a modest reduction of 0.4% from the previous estimate for this market. This reduction is primarily due to the impact of tariffs between the US and other countries. This is likely to directly affect the US through restricted access to limestone slurry pumps from Germany and mist eliminators from Finland, increasing costs for power plant emissions control. The effect will also be felt more widely due to reciprocal tariffs and the negative effect on the global economy and trade due to increased trade tensions and restrictions.

The growing demand for cleaner energy solutions is anticipated to drive the expansion of the wet flue gas desulfurization system market in the coming years. Several factors contribute to the rise of cleaner energy solutions, including stricter environmental regulations, advancements in renewable energy technologies, increasing consumer demand for sustainable practices, and the need to reduce greenhouse gas emissions. Wet flue gas desulfurization systems play a crucial role in these cleaner energy initiatives by effectively removing sulfur dioxide from emissions, thereby reducing air pollution and ensuring compliance with environmental standards. For instance, according to the International Energy Agency (IEA), a France-based autonomous intergovernmental organization, power generation from solar photovoltaic systems reached a record 270 TWh in 2022, representing a 26% increase from 2021. As a result, the growing demand for cleaner energy solutions is driving the growth of the wet flue gas desulfurization system market.

Key companies in the wet flue gas desulfurization system market are pursuing strategic partnerships to strengthen technology integration and broaden their market presence. A strategic partnership is a cooperative relationship between organizations that pool resources, expertise, and efforts to achieve shared goals. For example, in January 2023, Babcock & Wilcox (B&W), a U.S.-based provider of energy technology, expanded its environmental solutions portfolio through a strategic partnership with Hamon Research-Cottrell, an India-based specialist in air pollution control technologies. This partnership enhanced B&W’s flue gas desulfurization (FGD) capabilities, enabling the company to offer more comprehensive solutions for reducing sulfur dioxide and other emissions. By utilizing Hamon Research-Cottrell's technologies - such as wet and dry electrostatic precipitators, fabric filters, and scrubbers - B&W bolstered its capacity to support cleaner energy production for industries requiring advanced emissions control.

In January 2022, GE Power India Ltd., an India-based power generation and energy delivery services company, collaborated with Apollo International Group to improve the environmental performance of the Anuppur Thermal Power Plant (TPP) in Madhya Pradesh, India. This partnership aims to significantly cut sulfur dioxide (SO₂) emissions by 51,000 tons annually through the deployment of a wet flue gas desulfurization (WFGD) system. Apollo International Group is an India-based provider of integrated logistics solutions.

The sharp rise in U.S. tariffs and ensuing trade tensions in spring 2025 are heavily impacting the oil and gas industry, especially in areas such as exploration equipment, pipeline development, and refining operations. Increased import duties on drilling rigs, steel pipes, and specialized machinery have significantly raised capital expenditures across both upstream and downstream segments. Midstream players are grappling with cost surges for essential components like valves, compressors, and storage tanks, causing delays and disruptions in expansion projects. Refiners, meanwhile, are contending with higher expenses for imported catalysts and control systems critical to operational efficiency. In addition, retaliatory tariffs from major trade partners have curtailed U.S. exports of liquefied natural gas (LNG) and crude oil, reducing global competitiveness. In response, companies are ramping up investments in domestic manufacturing alliances, digital asset management tools, and diversified energy portfolios to maintain resilience and protect profitability.

A wet flue gas desulfurization (FGD) system is a technology designed to remove sulfur dioxide (SO2) from the exhaust gases of industrial processes, primarily from power plants. The system operates by spraying the flue gases with a wet slurry, usually containing limestone or lime, which reacts with the sulfur dioxide to create a solid byproduct that can be safely disposed of or repurposed.

The main types of wet flue gas desulfurization systems include spray towers, jet bubbling, and tray towers. A spray tower, a type of wet scrubber, cleans the gas by spraying it with a liquid absorbent to remove pollutants such as sulfur dioxide from industrial emissions. These systems are installed in both greenfield and brownfield projects and are used across various industries, including power generation, chemical and petrochemical production, cement manufacturing, metal processing and mining, and other sectors.
