Major trends in the forecast period include integration of digital technologies, shift towards dry FGD technologies, byproduct utilization, collaborations and partnerships, technological advancements in FGD systems.

The growing number of coal-fired power plants is anticipated to boost the flue gas desulfurization system market. Coal-fired power plants are facilities that produce electricity by burning coal. The rise in the number of these power plants necessitates the use of flue gas desulfurization systems to minimize harmful gas emissions. For example, in August 2022, the U.S. Energy Information Administration, a key agency in the U.S. for collecting, analyzing, and sharing energy information, published an article indicating that coal-fired power generation in the U.S. increased by 16%, reaching 898,679 GWh in 2021. Consequently, the rising number of coal-fired power plants is propelling the growth of the flue gas desulfurization system market.

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.

Stringent government regulations aimed at controlling air pollution are driving the growth of the flue gas desulfurization system market. Air pollution is increasing due to rising industrialization and urbanization. The flue gas desulfurization system effectively mitigates air pollution by reducing the amount of sulfur dioxide (SO2) emitted into the atmosphere. Governments are implementing various initiatives, including investments in different projects, to combat air pollution. For instance, in November 2022, the US Environmental Protection Agency (EPA), the federal agency responsible for environmental protection issues, announced that the Inflation Reduction Act and American Rescue Plan, led by Vice President Biden, would allocate $53.4 million to 132 air monitoring projects across 37 states to improve community-level air quality monitoring in the United States. The programs primarily target communities that have historically been disadvantaged, disenfranchised, and heavily affected by pollution.

Collaboration emerges as a pivotal trend within the flue gas desulfurization system market as major industry players engage in partnerships to maintain their market presence. For instance, in January 2022, General Electric (GE) collaborated with Apollo International Limited for MB Power Madhya Pradesh Ltd to develop an entire Wet Flue Gas Desulfurization (WFGD) system. This comprehensive project encompasses the design, engineering, and provision of crucial WFGD system components. Upon completion, the system is projected to facilitate the cleaning of 7.4 million cubic meters of flue gas per hour, resulting in the annual elimination of 51,000 tons of SO2.

Major companies in the flue gas desulfurization system market are pursuing mergers and acquisitions to maintain their competitive position. M&A activities are intricate and involve a range of legal, financial, and operational considerations. Companies engage in M&A for various strategic reasons, such as achieving economies of scale, entering new markets, diversifying their product or service offerings, gaining access to intellectual property, and eliminating competitors. For example, in January 2022, General Electric, a US-based infrastructure and financial services company, partnered with Apollo International Limited. This collaboration aims to design and implement a Wet Flue Gas Desulfurization (WFGD) system for the Anuppur Thermal Power Plant, with the goal of reducing sulfur dioxide (SO2) emissions and ensuring compliance with environmental regulations. Apollo International Limited is an India-based company involved in green energy, infrastructure, logistics, fashion manufacturing, and global trading and distribution, while MB Power is a subsidiary of Hindustan Thermal Projects Limited (HTPL).

Flue gas desulfurization systems are designed to eliminate sulfur dioxide (SO2) from industrial fuel gas emissions generated through combustion processes. They are instrumental in reducing SO2 emissions in various industries.

These systems primarily come in three types such as wet FGD systems, spray dry FGD systems, and dry/semi-dry FGD systems. Wet FGD systems involve scrubbing the gas with an alkaline sorbent to effectively remove sulfur dioxide. These systems are specifically engineered to eliminate SO2 from flue gases and find application in power generation, chemical processing, iron and steel production, metal processing and mining, cement manufacturing, paper and pulp industries, among others. They are deployed in both greenfield (new) and brownfield (existing) installations to address emission concerns.
