Industrial DeNOx Systems and Services Market Report 2026

The industrial denox systems and services market size has grown strongly in recent years. It will grow from $6.42 billion in 2025 to $6.97 billion in 2026 at a compound annual growth rate (CAGR) of 8.5%. The growth in the historic period can be attributed to stricter air quality regulations, expansion of thermal power generation, adoption of industrial emission control systems, increased monitoring of nox emissions, availability of catalytic reduction technologies.

The industrial denox systems and services market size is expected to see strong growth in the next few years. It will grow to $9.57 billion in 2030 at a compound annual growth rate (CAGR) of 8.3%. The growth in the forecast period can be attributed to increasing tightening of emission standards, rising investments in clean industrial processes, expansion of digital emission monitoring solutions, growing demand for low-nox industrial equipment, increasing retrofitting of aging plants. Major trends in the forecast period include increasing deployment of scr and sncr technologies, rising demand for retrofit and modernization services, growing use of continuous emission monitoring systems, expansion of remote monitoring and diagnostics, enhanced focus on energy-efficient nox reduction.

The rising industrialization is expected to drive the growth of the industrial DeNOx systems and services market in the coming years. Industrialization is the process of transforming an economy from primarily agricultural to one based on the manufacturing of goods, supported by the development of industries, infrastructure, and technological advancements. The increase in industrialization is fueled by growing demand for mass production of goods due to expanding global populations and urbanization. Industrial DeNOx systems and services help reduce nitrogen oxide emissions from manufacturing and energy processes, ensuring cleaner operations and compliance with environmental regulations. For example, in September 2025, Trading Economics, a U.S.-based platform providing economic data, reported that industrial output in Saudi Arabia grew 6.5 percent year-on-year in July 2025, accelerating from a revised 6.1 percent growth recorded in June. Therefore, rising industrialization is driving growth in the industrial DeNOx systems and services market.

Leading companies in the industrial DeNOx systems and services market are investing in high-performance gas purification systems for applications such as glass line production to improve emission control efficiency, reduce nitrogen oxide output, and comply with strict environmental regulations. A high-performance gas purification system is advanced technology designed to remove harmful gases and impurities, including nitrogen oxides (NOx), from industrial exhaust streams to ensure cleaner emissions and regulatory compliance. For instance, in October 2024, GEA Group AG, a Germany-based engineering company, received a contract for Line II, which includes a state-of-the-art GEA gas cleaning system integrating a DeNOx reactor along with storage, transport, and reagent dosing components. This system achieves a significant reduction in nitrogen oxide (NOx) emissions to 500 mg/Nm³, supporting Pilkington’s compliance with stringent environmental regulations and sustainability goals. GEA’s technical collaboration also prepared the plant for future energy efficiency improvements, including potential integration of a waste heat recovery system.

In September 2024, Somas Instrument AB, a Sweden-based manufacturer of control and on/off valves, partnered with Accelleron to enhance service support for valves used in exhaust aftertreatment systems, including selective catalytic reduction (SCR) and exhaust gas recirculation (EGR). Under this partnership, Accelleron was appointed as the authorized global service provider for Somas’ marine customers, with trained engineers ensuring reliable maintenance and performance. The collaboration strengthens global service capabilities and operational reliability for DeNOx systems in the marine sector. Accelleron is a Switzerland-based provider of turbocharging, fuel injection, and digital solutions for the marine and energy industries.
