The gas cleaning technologies market was worth USD 6.4 billion in 2023 and will be worth USD 9.5 billion by 2030, growing at a CAGR of 5.8% during the forecast period.

 

The global Gas Cleaning Technologies market is mainly fueled by the rising prominence of industrial emission norms and environmental consciousness. For instance, the power generation sector, cement, and chemicals industries need to install gas cleaning systems to meet new emission regulation standards, hence increasing demand. In 2023, restrictions on industrial emissions increased worldwide, especially in key economies, which boosted the adoption of innovations in the cleaning industrial gases, especially in the Asia Pacific region, which has a relatively higher growth industrial sector. One of the latest trends implemented involves using enhanced filters and scourging in power plants to reduce SO2 and NO? emissions.  One example is the usage of super-advanced wet scrubber systems in coal-fired power stations in China due to stringent air quality norms in the country, thus increasing the demand in the market.

 

A major opportunity in the Gas Cleaning Technologies market lies in the rise of clean energy and carbon capture initiatives. CCS projects are expected to grow at a rate of 15% per year, and the global requirement for gas-cleaning technology is becoming higher through power generation and cement manufacturing units. For instance, gas cleaning technologies that can be incorporated into the CCS systems may help in mitigating emissions of unwanted gases, including CO2, in the atmosphere. One such development is the improvement of electrostatic precipitators and scrubber technology for use in CCS projects in the European market as the region seeks to attain a zero-emission status by 2050.

Segment Analysis for the Gas Cleaning Technologies Market

By Technology:

Leading Segment: Electrostatic Precipitators (ESP)

Electrostatic precipitators hold the largest market share of around 35% due to their extensive use in power plants, cement manufacturing & steel production for controlling particulate matter emissions. ESP systems are preferred for their ability to handle large volumes of gas and remove fine particles effectively. For example, power generation facilities in North America and Europe widely implement ESPs to meet stringent environmental regulations. The segment is projected to grow at a steady CAGR of 6.5% as industries prioritize compliance with emission standards.

Fastest-Growing Segment: Selective Catalytic Reduction (SCR) Systems

SCR systems are growing rapidly at a CAGR of 9% due to their high efficiency in reducing nitrogen oxides (NOx) emissions. The adoption is particularly high in regions with strict air quality standards, such as Europe & North America. For instance, SCR technology is extensively used in coal-fired power plants and large industrial boilers to comply with NOx emission limits mandated by government regulations like the European Industrial Emissions Directive.

 

By Gas Type:

Leading Segment: Sulfur Dioxide (SO2)

SO2 gas cleaning technologies dominate the market, accounting for approximately 30% of the market share. These systems, including flue gas desulfurization (FGD), are extensively used in power generation & industrial applications to reduce emissions caused by burning fossil fuels. For example, China and India have made FGD mandatory in coal-fired power plants, driving demand for SO2 control technologies.

Fastest-Growing Segment: Volatile Organic Compounds (VOCs)

The VOC segment is growing at a CAGR of 10%, driven by the increasing adoption of activated carbon injection (ACI) systems & scrubbers in industries such as chemicals, oil & gas, and food & beverage. VOC emissions are tightly regulated in regions like North America & Europe, boosting demand for advanced gas cleaning technologies.

 

By Application:

Leading Segment: Power Generation

The power generation sector leads with over 35% of the market share, fueled by its reliance on coal and natural gas-fired plants. Technologies like ESPs, wet scrubbers, and SCR systems are extensively used in this sector to reduce emissions of SO2, NOx, and particulate matter. The U.S. Environmental Protection Agency's Clean Air Act has propelled significant investments in emission control systems for power plants.

Fastest-Growing Segment: Chemicals & Petrochemicals

The chemicals & petrochemicals sector is growing at a CAGR of 8.7%, driven by the need to control hazardous gases such as VOCs, SO2, & ammonia. Industries in this sector are investing in advanced scrubber systems & activated carbon technologies to meet emission standards. For example, Dow Chemical has incorporated state-of-the-art gas cleaning technologies in its production facilities to reduce its environmental footprint.

 

By Region:

Leading Region: Asia Pacific

Asia Pacific holds the largest market share of 40%, led by industrial growth in countries like China, India & Japan. The region's heavy reliance on coal-fired power plants and expanding cement and steel industries drive demand for gas cleaning technologies. Governments are enforcing stringent emission standards, with initiatives like India’s mandate for flue gas desulfurization systems in power plants, propelling the market.

Fastest-Growing Region: North America

North America is the fastest-growing region, with a CAGR of 8.5%, driven by stringent regulations such as the U.S. Clean Air Act & Canada’s air quality management policies. The adoption of SCR and ACI systems is increasing across power plants, oil refineries, and waste incineration facilities. For example, the U.S. has seen significant investments in SCR systems to reduce NOx emissions from industrial boilers and power plants.
