세계의 선택적 촉매 환원 시장 예측(-2032년) : 환원제 유형, 촉매 유형, 컴포넌트, 용도, 최종사용자, 지역별 분석

According to Stratistics MRC, the Global Selective Catalytic Reduction Market is accounted for $15.4 billion in 2025 and is expected to reach $25.1 billion by 2032 growing at a CAGR of 7.2% during the forecast period. Selective Catalytic Reduction (SCR) is an advanced emission control technology that reduces nitrogen oxides (NOx) from exhaust gases through a chemical reaction with a reductant, typically ammonia or urea, in the presence of a catalyst. This process converts harmful NOx emissions into harmless nitrogen (N2) and water vapor (H2O), significantly lowering air pollution levels. Widely used in power plants, industrial boilers, and diesel engines, SCR enhances compliance with stringent environmental regulations such as Euro 6 and Tier 4 standards.

According to the International Council on Clean Transportation (ICCT), Euro 6d standards require NOx emissions from diesel passenger cars to be below 80 mg/km, while China 6 standards limit NOx emissions to 35 mg/km for light-duty vehicles.

Market Dynamics:

Driver:

Growing industrialization and power generation

The accelerating pace of industrialization and expanding power generation activities worldwide are pivotal drivers for the selective catalytic reduction (SCR) market, particularly in emerging economies. Stringent emission norms, such as China's National VI and India's BS-VI standards, mandate NOx reduction in coal-fired plants and heavy industries, propelling SCR adoption. The integration of SCR technology in combined heat and power (CHP) systems further supports compliance with global air quality regulations accelerating market penetration.

Restraint:

Dependency on urea supply (DEF)

Urea, a critical component in SCR systems, is used to produce ammonia for NOx reduction in diesel engines. Fluctuations in urea availability due to supply chain disruptions or geopolitical factors can lead to increased costs and operational inefficiencies. Additionally, reliance on urea imports in certain regions exacerbates vulnerability to market volatility. Thus limited urea supply can hinder the adoption of SCR technology, impacting compliance with stringent emission regulations.

Opportunity:

Expanding use in marine and aviation sectors

Stringent emission regulations, such as IMO Tier III standards, are propelling the adoption of SCR systems to reduce nitrogen oxide (NOx) emissions from ships. Similarly, in aviation, SCR technology is being explored to meet evolving environmental standards for ground support equipment and auxiliary power units. These applications are fostering advancements in SCR catalysts, lightweight designs, and compact systems tailored for space-constrained environments.

Threat:

Competition from alternative emission control technologies

Emerging technologies, such as Exhaust Gas Recirculation (EGR) and Lean NOx Traps (LNT), offer cost-effective and efficient solutions for reducing nitrogen oxide emissions. These alternatives can outperform SCR systems in specific applications, leading to reduced adoption of SCR technology. Additionally, advancements in hybrid and electric vehicle technologies further diminish the demand for SCR systems, as these vehicles produce fewer emissions.

Covid-19 Impact:

The pandemic initially disrupted SCR supply chains, delaying component manufacturing and installation projects amid lockdowns. Reduced industrial activity and deferred emission compliance timelines temporarily slowed demand in 2020-2021. However, post-pandemic recovery packages, such as the EU's Green Deal and U.S. Infrastructure Bill, prioritized funding for clean air technologies, reviving SCR investments. The market is now rebounding, driven by pent-up demand and accelerated regulatory enforcement.

The vanadium-based catalysts segment is expected to be the largest during the forecast period

The vanadium-based catalysts segment is expected to account for the largest market share during the forecast period due to their high efficiency in reducing nitrogen oxides (NOx) emissions. These catalysts, typically composed of V2O5 supported on TiO2, operate effectively across a wide temperature range, making them suitable for diverse industrial applications. Their ability to achieve high NOx conversion rates, even at low temperatures, enhances their appeal in stringent regulatory environments. However, concerns over vanadium toxicity and disposal challenges may impact market growth.

The power plants segment is expected to have the highest CAGR during the forecast period

Over the forecast period, the power plants segment is predicted to witness the highest growth rate. SCR systems are widely adopted in coal-fired and natural gas-fired power plants to comply with stringent environmental regulations aimed at reducing NOx emissions. The increasing global energy demand and the transition to cleaner energy sources further boost the adoption of SCR technology in power generation. Additionally, the shift towards renewable energy sources may impact the long-term demand for SCR systems in power plants.

Region with largest share:

During the forecast period, the Asia Pacific region is expected to hold the largest market share due to rapid industrialization and increasing energy demand. The presence of major manufacturing hubs, coupled with stringent emission control regulations, has fueled the adoption of SCR technology across industries. China and India, being among the largest contributors to industrial emissions, are heavily investing in NOx reduction solutions. The expansion of transportation, power generation, and petrochemical sectors in the region continues to support the market's growth.

Region with highest CAGR:

Over the forecast period, the North America region is anticipated to exhibit the highest CAGR driven by stringent environmental regulations and advancements in emission control technologies. The U.S. and Canada have enforced strict NOx emission standards, compelling industries to adopt SCR systems for compliance. The growing focus on reducing greenhouse gas emissions in power plants, automotive, and marine industries is further accelerating market growth.
