Gas Cleaning Technologies Market Report 2026

The gas cleaning technologies market size has grown strongly in recent years. It will grow from $34.54 billion in 2025 to $36.64 billion in 2026 at a compound annual growth rate (CAGR) of 6.1%. The growth in the historic period can be attributed to stricter environmental regulations, expansion of industrial manufacturing capacity, increased installation of pollution control equipment, growth in fossil fuel-based power generation, adoption of particulate filtration systems.

The gas cleaning technologies market size is expected to see strong growth in the next few years. It will grow to $45.82 billion in 2030 at a compound annual growth rate (CAGR) of 5.7%. The growth in the forecast period can be attributed to increasing investments in clean industrial technologies, rising demand for low-emission production processes, expansion of industrial decarbonization initiatives, growing focus on real-time emission monitoring, increasing replacement of legacy gas cleaning systems. Major trends in the forecast period include increasing deployment of advanced emission control systems, rising adoption of modular gas cleaning units, growing integration of digital monitoring solutions, expansion of multi-pollutant removal technologies, enhanced focus on energy-efficient gas treatment.

The increase in oil and gas production activities is expected to drive the growth of the gas cleaning technologies market going forward. Oil and gas production involves the extraction of crude oil and natural gas to meet industrial, commercial, and residential energy requirements. The expansion of oil and gas production is primarily driven by rising global energy demand, prompting producers in key regions to scale up output levels. Gas cleaning technologies support oil and gas operations by removing contaminants and harmful pollutants from exhaust gases and associated gas streams, reducing emissions, and ensuring compliance with stringent environmental and safety regulations. For example, in April 2025, according to the US Energy Information Administration (EIA), a US-based government energy data agency, US crude oil production increased by 270,000 barrels per day in 2024 to average 13.2 million barrels per day, representing a 2% rise compared to 2023. As a result, the growing scale of oil and gas production activities is contributing to the expansion of the gas cleaning technologies market.

Key players and leading technology providers in the gas cleaning technologies market are increasingly focusing on the development of advanced digital tools to deliver more flexible, efficient, and resource-optimized gas cleaning solutions. Digital tools in gas cleaning systems refer to software-driven technologies that monitor, control, and optimize gas treatment processes, improving operational performance while supporting regulatory compliance and reducing energy and water consumption. For instance, in December 2023, Metso Corporation, a Finland-based industrial machinery company, introduced the High-Efficiency Scrubber (HES) Optimizer. This digital solution improves energy efficiency in gas cleaning plants by optimizing pressure drop in Venturi scrubbers through real-time data analysis and internal calculations. The system ensures consistent impurity removal despite fluctuations in gas flow and dust loads, supporting stable operations and adherence to environmental standards.

In February 2024, Cycle Group Limited, a UK-based biomethane provider, acquired Biogasclean A/S for an undisclosed amount. Through this acquisition, Cycle Group aimed to strengthen its capabilities in producing fully circular green gas and position itself at the forefront of synthetic green gas innovation using carbon capture and utilization technologies. Biogasclean A/S is a Denmark-based company specializing in gas cleaning solutions, with a focus on biological desulfurization and methanation systems.
