Diesel Exhaust Fluid (DEF) is a solution used in contemporary engines powered by diesel to minimize hazardous emissions, specifically nitrogen oxides (NOx). DEF is a nitrogenous waste-deionized water mixture that is pumped into the exhaust system of diesel engines, where it interacts with NOx to produce harmless nitrogen and water vapor. On a vehicle, DEF is typically kept in a separate tank from the tank used for diesel fuel. The DEF tank is typically situated next to the gasoline tank and is made to be simple to refill. Depending on the size of the car and its engine, the DEF tank can vary in size, although it is often big enough to endure several thousand miles of driving.
Key factors driving the growth of DEF include environmental regulations as many countries and regions have introduced strict emission regulations, which require diesel engine manufacturers to use DEF to meet these standards. Increasing demand for diesel vehicles is also a growth factor as diesel engines are more fuel-efficient than gasoline engines, and they are widely used in heavy-duty vehicles, such as trucks, buses, and construction equipment. Growing awareness about environmental issues. Selective Catalytic Reduction (SCR) technology is growing and becoming more prevalent in diesel engines, especially in heavy-duty vehicles. SCR technology requires the usage of DEF, which is propelling the DEF industry forward. For instance, The Australian government is encouraging the domestic production of DEF in an effort to increase the nation's self-sufficiency and the resilience of the vital transportation energy system. It is essential to Australia's transport and logistics sectors as it lowers dangerous nitrogen oxide emissions from diesel engines. The major ingredient in DEF, technical grade urea, was in short supply during the summer of 2021, exposing Australia's excessive reliance on imports.
In January 2020, Indian Oil Corporation Ltd. and Cummins Technologies entered into an agreement for bulk dispensing of Indian Oil Corporation’s DEF, also referred to as IOC ClearBlue, in their advanced engines with Selective Catalytic Reduction (SCR) systems. Bulk dispensing of DEF is anticipated to offer better cost viability to bus and truck owners, in comparison to packed products.
The Covid-19 pandemic caused disruptions in the global supply chain, including the production and distribution of DEF. The shutdown of factories and reduced transportation capacity have led to shortages of DEF in some areas. In addition, the pandemic has a decrease in demand for diesel fuel, which has also affected the DEF industry. Many industries that use diesel engines, such as transportation and construction, had experienced a decline in business during the pandemic.
