Wet Flue Gas Desulfurization System Market Report 2026

The wet flue gas desulfurization system market size has grown strongly in recent years. It will grow from $18.38 billion in 2025 to $19.51 billion in 2026 at a compound annual growth rate (CAGR) of 6.1%. The growth in the historic period can be attributed to implementation of sulfur emission regulations, expansion of coal fired power generation, early adoption of air pollution control technologies, industrialization growth, public pressure to reduce air pollution.

The wet flue gas desulfurization system market size is expected to see strong growth in the next few years. It will grow to $24.81 billion in 2030 at a compound annual growth rate (CAGR) of 6.2%. The growth in the forecast period can be attributed to stricter emission compliance norms, modernization of aging power plants, expansion of industrial pollution control, adoption of digital monitoring systems, demand for cleaner industrial processes. Major trends in the forecast period include increasing installation of wet fgd systems in power plants, rising adoption of multi stage spray tower designs, growing retrofit of fgd systems in existing plants, expansion of fgd applications in industrial manufacturing, increasing focus on byproduct utilization.

The growing demand for cleaner energy solutions is expected to drive the growth of the wet flue gas desulfurization (WFGD) system market in the coming years. Demand for cleaner energy is increasing due to stricter environmental regulations, advancements in renewable energy technologies, rising consumer preference for sustainable practices, and the need to reduce greenhouse gas emissions. WFGD systems support cleaner energy initiatives by efficiently removing sulfur dioxide from flue gas emissions, reducing air pollution, and ensuring compliance with environmental standards. For example, in November 2025, the European Environment Agency (EEA) reported that in 2024, 25.4% of the European Union’s final energy consumption came from renewable sources, up about one percentage point from 2023, moving the EU closer to its 2030 renewable energy target of 42.5%. Therefore, the rising demand for cleaner energy solutions is propelling 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 October 2023, Valmet Oyj, a Finland-based provider of energy and environmental solutions, partnered with Megha Engineering & Infrastructures Ltd. to implement a wet flue gas desulfurization (FGD) system at a petroleum refinery in western India. Through this collaboration, Valmet and Megha aimed to reduce sulfur oxide (SOx) emissions from the refinery’s boiler flue gases and ensure compliance with India’s environmental regulations. The partnership leveraged Megha’s local engineering, procurement, and construction (EPC) expertise along with Valmet’s advanced FGD technology. Megha Engineering & Infrastructures Limited is an India-based EPC company that serves industrial and infrastructure projects.
