Global Diesel Exhaust Fluid Overview

Diesel exhaust fluid (DEF), also known as AdBlue, is a consumable fluid used in selective catalytic reduction (SCR) systems to control nitrogen oxide (NOx) emissions from diesel engines. DEF is a solution of urea and deionized water, typically 32.5% urea by weight. When injected into the exhaust stream, the urea reacts with NOx to form nitrogen and water, which are harmless by products.

The use of SCR and DEF, it has been found that engine improvements actually made it possible to get more power from the engine. The addition of DEF fluid for fleet management market not only gives extra power but will also add mileage to fleet operations. As a fleet operator today, with the use of DEF assured of the increased life expectancy of vehicles. Now, since the engines run extra efficiently so that consumers stop worrying about any wear and tear on the engine components which is likely and expectedly to reduce the chance of frequent repairs and maintenance. This will in turn reduce overall fleet maintenance costs and will help manage fleet with more control effectively. The efficiency of an SCR engine that uses DEF allows to worry less about engine maintenance now and in the future. This advantages have led to increase the adoption of Diesel exhaust fluid market in the forecasted period.

Back in 2010, the Environment Protection Agency (EPA) mandated the use of Selective Catalytic Reduction (SCR) in all diesel vehicles. However, SCR is not a new invention, in fact it has been around for nearly half a century! And in India with the advent of Bharat Stage VI (BSVI) norms, diesel engines will have to reduce their HC+NOx (hydro carbon + nitrogen oxides) by 43%, their NOx levels by 68% and particulate matter levels by 82%. This is where the role of Diesel Exhaust Fluid (DEF) comes into play as DEF is going to work as a catalyst with Selective Catalytic Reduction (SCR) towards improving the overall health of the environment and making diesel vehicle a responsible choice and a more viable option for the future, which leads to growth of the market.

As these technologies are becoming cheaper due to various government support the diesel exhaust fluid market is expected to grow in forecasted period.

Global Trends that are Shaping Diesel Exhaust Fluid Market

Impact of Exhaust Emission Standards and Norms, No Fixed Prices for Diesel Exhaust Fluid Market

According to the engine range, the most recent Tier 4 emission laws in the US have replaced the Tier 4 transitional, Tier 3, and Tier 2 requirements. Diesel engines must now adhere to the restrictions set out in the EPA Nonroad Compression Ignition Exhaust Emission Standards for numerous upstream oil and gas activities. Compared to Tier 3 and Tier 2, the reduction of nitrous oxides (NOx) and particulate matter (PM) has been the primary emphasis of current Tier 4 emission limits. The U.S. EPA has decided to limit the sulphur content of the diesel fuel used by these engines to 15 parts per million (ppm) with the most current Tier 4 emission requirements, a 97% reduction from the original requirement of 500 ppm. Diesel Exhaust Fluid Market with these restrictions, the European Commission, like the EPA, decided to concentrate on lowering emissions of carbon monoxide (CO), hydrocarbons (HC), nitrogen oxides (NOx), and particulate matter. The most recent and stringent stage of these restrictions is Stage V. The key points of Stage V emissions in relation to upstream oil and gas applications and more detail of each country-wise regulation and their effect on the market are covered in the report.

Since urea and de-ionized water make up DEF, the price of urea has some influence on the price of DEF. Agriculture is the main use that affects the price of urea on a worldwide scale. The agriculture sector has an impact on urea pricing. Since it is depending on supply and demand from the agricultural sector, the price of urea is far more unpredictable than the price of diesel. Crops are sown at the start of the year in several northern hemisphere nations. As a result, urea is expensive. Prices for urea decrease after the crops are prepared for winter harvest. According to the graph below, urea prices rise at the start of every year as a result of planters' increased demand from the agricultural sector. The price of urea was at its lowest in 2020 more than ten years ago, according to Yara International (Norway). Since urea is the primary component of DEF, changes in urea prices have an impact on DEF costs and hence present a challenge for the global market for diesel exhaust fluid.

Diesel Exhaust Fluid Market Segment Analysis:

Based on Vehicle Type, the diesel exhaust fluid market (DEF) is segmented into Passenger Car, HCVs, and LCVs. Heavy commercial vehicle (HCV) dominates the diesel exhaust fluid market accounting for over 60% of the global diesel exhaust fluid market in 2023. This market is growing due to higher fuel consumption than light commercial vehicles (LCVs) and passenger cars, which means they consume more diesel exhaust fluid, as diesel exhaust fluid is used to reduce nitrogen oxide (NOx) emissions from diesel engines. As HCVs emit more pollution than LCVs and passenger cars, including NOx that contribute to air pollution and health problem so HCVs have stringent emission standards. Selective catalytic reduction (SCR) systems are the most effective technology for reducing NOx emissions from diesel engines. SCR systems require DEF to function properly. HCVs are more likely to have SCR systems installed than LCVs and passenger cars. Globally, demand for the HCV vehicle segment has grown in industrialized and developing countries thanks to improved product offerings or higher economic activity. Businesses must abide by the laws and standards of the country in which they conduct business. Regulation compliance result in a rise in demand for DEF products. More than 500,000 diesel vehicles in Europe are currently using this technology, and the fleet is expanding by roughly 25,000 trucks each month.
