Automotive Selective Catalytic Reduction (SCR) Market Size, Trends, & Insights By 2033

(MENAFN- Straits Research) Introduction

Selective catalytic reduction (SCR) is a sophisticated way of actively reducing emissions, wherein a catalyst is utilized to inject a liquid-reductant agent into the exhaust stream of a diesel engine. Diesel exhaust fluid (DEF) is urea designed for use in automobiles and is the most frequent reducing agent used. This molecule kickstarts a chemical reaction that converts nitrous oxide to harmless byproducts like water, nitrogen, and trace amounts of carbon

Market Dynamics Implementation of Emission Control Regulations by the government Drives the Global Market

The government has enacted rigorous regulations aimed at regulating the release of pollutants stemming from the combustion of diverse fuels, such as diesel fuel, fuel oil, petrol, gasoline, biodiesel, and comparable substances, in automobiles. The Euro 6 standard, as mandated by the European Union Directive, serves as the latest emission regulation. Its major aim is to address the release of harmful gases, including nitrogen oxide, carbon monoxide, and hydrocarbons, from vehicle exhaust systems.

Likewise, catalyst converters are a feature of car catalysts. The emission control device helps comply with government emissions requirements by converting harmful and offensive gases released by engines into less dangerous pollutants. As a result, the strict enforcement of laws governing pollution control acts as a stimulant for the rise in demand for automobile selective catalytic reduction technology , propelling the market's worldwide growth.

Key players in the emission reduction technology market are investing in improving and developing catalysts. For instance, Johnson Matthey Inc., a leading automotive catalyst producer, focuses on developing a three-way catalyst for future vehicles, improving fuel efficiency and reducing carbon dioxide (CO2) emissions substantially at lower operating temperatures. A three-way catalyst can reduce the emitted pollutants from vehicles at 100% conversion efficiency at its operational temperature, above 400oC, which is considerably higher. Such innovations in automotive catalysts are anticipated to provide future growth opportunities for the market.
