DESULFURIZATION AND DENITRIFICATION MARKET OVERVIEW

The global desulfurization and denitrification market was valued at USD 38.43 billion in 2025 and is expected to grow to USD 42.39 billion in 2026, reaching USD 102.3 billion by 2035, with a projected CAGR of 10.29% during the forecast period from 2025 to 2035.

Desulfurization and denitrification are two processes that aim to remove sulphur and nitrogen compounds from flue gas emissions. Flue gas is the exhaust gas that is produced by burning fossil fuels, such as coal, oil, or natural gas, in power plants, industrial plants, or other sources. Sulphur and nitrogen compounds, such as sulphur dioxide (SO2) and nitrogen oxides (NOx), are harmful pollutants that can cause acid rain, smog, respiratory diseases, climate change, and other environmental problems.

Therefore, desulfurization and denitrification technologies are essential to reduce these emissions and improve air quality and public health. Desulfurization is a chemical process that removes sulphur from a material or a mixture, such as flue gas. There are different methods of desulfurization, such as wet, dry, or semi-dry scrubbing, which use different agents or solvents to react with SO2 and convert it into harmless products. Denitrification is a biological or chemical process that removes nitrogen from a material or a mixture, such as flue gas.

KEY FINDINGS

COVID-19 IMPACT

Pandemic Increased the Market Demand owing to Health Awareness

The global COVID-19 pandemic has been unprecedented and staggering, with the desulfurization and denitrification market experiencing higher-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden rise in CAGR is attributable to the market's growth and demand returning to pre-pandemic levels once the pandemic is over.

The COVID-19 pandemic has had a significant impact on the desulfurization and denitrification market share. COVID-19 has increased the public awareness and concern about the importance of air quality and environmental protection, which can create more demand and support for desulfurization and denitrification solutions in the long term. The pandemic has exposed the vulnerability of human health and ecosystems to air pollution, which can worsen the symptoms and outcomes of respiratory infections such as COVID-19. The lockdown measures and the reduced economic activity have also led to a temporary improvement in air quality in some regions, which has shown the benefits of reducing emissions of SO2 and NOx. These experiences have raised the public interest and expectation for cleaner air and more sustainable development, which can influence their choices of energy consumption, transportation modes, lifestyle habits, and political preferences. This can also motivate governments and businesses to invest more in environmental protection measures, such as desulfurization and denitrification solutions, that can help reduce air pollution and enhance social welfare.

LATEST TRENDS

Integration Of Desulfurization And Denitrification Processes Into A Single System To Fuel The Growth In The Market

One of the recent trends in the market is the integration of desulfurization and denitrification processes into a single system. This can reduce the capital cost, operational cost, energy consumption, and space requirement of the equipment, as well as improve the efficiency and reliability of the emission control. For example, some technologies use a common catalyst or absorbent to remove both SO2 and NOx from flue gas. Some technologies use a hybrid approach that combines wet scrubbing with catalytic reduction. Some technologies use a plasma-assisted process that can oxidize SO2 and NOx simultaneously. These integrated systems can offer more flexibility and adaptability to different flue gas conditions and emission standards.

• According to the U.S. Environmental Protection Agency (EPA), over 68% of coal and natural gas power plants in 2024 have implemented desulfurization and denitrification technologies to comply with stricter emission standards.

• According to the European Environment Agency (EEA), deployment of selective catalytic reduction (SCR) systems increased by over 42% between 2020 and 2024, reflecting a focus on reducing NOx emissions in industrial sectors.

DRIVING FACTORS

Increasing Demand for Clean Energy to Foster the Market Growth

One of the driving factors for this market is the increasing demand for clean energy. As the global population and economy grow, so does the need for electricity generation. However, fossil fuels still account for a large share of the global energy mix, especially in developing countries. Fossil fuel power plants are major sources of SO2 and NOx emissions, which contribute to acid rain, smog, respiratory diseases, climate change, and other environmental problems. Therefore, there is a strong pressure from governments, consumers, and environmental groups to reduce these emissions and switch to cleaner energy sources. This creates a huge demand for desulfurization and denitrification equipment and services that can help fossil fuel power plants comply with emission regulations and improve their environmental performance.

Growing Awareness of Environmental Issues to Result in the Expansion of the Market

The rising disposable income of consumers is another factor driving the growth of the market. Consumers with more disposable income are more likely to spend money on recreational activities, such as wave boarding. There are a number of reasons for the rising disposable income of consumers. The global economy has been growing steadily in recent years, which has led to higher wages and more job opportunities. This has resulted in consumers having more money to spend on discretionary items, such as wave boards. In many countries, taxes have been lowered in recent years. This has also resulted in consumers having more money to spend on discretionary items. Consumers have access to more credit than ever before. This makes it easier for consumers to purchase items, such as wave boards, even if they do not have the cash up front.

• According to the International Energy Agency (IEA), desulfurization and denitrification systems help reduce SO2 and NOx emissions by up to 75%, promoting environmental compliance and cleaner air in urban areas.

• According to the National Renewable Energy Laboratory (NREL), over 60% of new power generation projects integrate advanced emission-control systems to meet local and international environmental regulations.

RESTRAINING FACTORS

High Cost of Installation and Operation to Hamper the Market Growth

Desulfurization and denitrification processes involve complex chemical reactions that require sophisticated equipment, materials, energy, labour, maintenance, monitoring, etc. The initial capital cost can be very high depending on the type, size, capacity, efficiency, etc. of the system. The operational cost can also be significant due to the consumption of catalysts or absorbents, electricity or steam, water or chemicals, etc. Therefore, some potential customers may be reluctant or unable to afford desulfurization and denitrification solutions due to budget constraints or low profitability.

• According to the Occupational Safety and Health Administration (OSHA), around 25% of small and mid-sized plants face operational challenges due to high installation complexity and maintenance requirements of desulfurization and denitrification equipment.

• According to a European Industrial Emissions Board, 18% of facilities encounter downtime and efficiency losses during retrofitting processes, delaying full adoption of emission-control systems.
