The automotive industry continues to be a hotbed of patent innovation. The automotive industry is experiencing innovation in selective catalytic reduction (SCR) catalysts due to strict emission regulations, rising demand for clean vehicles, and technological advancements. New catalyst materials, coating technologies, substrate designs, and formulations are being developed to make SCR more effective, durable, and cost-effective. Increasing electrification of the automotive fleet and the development of new fuels and fuel blends are also driving this innovation. This is resulting in more efficient, durable, cost-effective, and versatile SCR catalysts. The automotive industry is embracing new technologies in SCR catalysts, including copper zeolite catalysts, new coating technologies, and new substrate designs. Copper zeolite catalysts are effective at reducing nitrogen oxide (NOx) emissions at high temperatures, making them ideal for diesel engines. New coating methods and substrate designs are being developed to improve efficiency and durability. SCR catalysts are also being developed for new fuels and fuel blends, such as biodiesel and renewable diesel. In the last three years alone, there have been over 1.7 million patents filed and granted in the automotive industry, according to GlobalData’s report on Environmental sustainability in automotive: SCR catalysts.
