The automotive industry continues to be a hotbed of innovation. Activity is driven by government regulations and environmentally conscious consumers, and growing importance of technologies such as high-efficiency particulate air (HEPA) filters and ultra-low particulate air (ULPA) filters. In the last three years alone, there have been over 1.2 million patents filed and granted in the automotive industry, according to GlobalData’s report on Environmental sustainability in Automotive: Zeolites for exhaust filtering.

According to GlobalData’s Technology Foresights, which uses over 619,000 patents to analyse innovation intensity for the automotive industry, there are 290+ innovation areas that will shape the future of the industry.
Zeolites for exhaust filtering is a key innovation area in environmental sustainability
Zeolites are a filtration material used for hydrocarbon trapping, selective catalytic reduction of nitrogen oxides (NOx) with NH3 (NH3-SCR), and hydrocarbon NOx reduction applications. Zeolites capture these harmful pollutants that are not taken care of by the catalytic converter. They have a natural porosity because of their crystalline structure, which gives them the ability to trap particles in their pores, called cages.
GlobalData’s analysis also uncovers the companies at the forefront of each innovation area and assesses the potential reach and impact of their patenting activity across different applications and geographies. According to GlobalData, there are 50 companies, spanning technology vendors, established automotive companies, and up-and-coming start-ups engaged in the development and application of zeolites for exhaust filtering.
Key players in zeolites for exhaust filtering – a disruptive innovation in the automotive industry
‘Application diversity’ measures the number of different applications identified for each relevant patent. It broadly splits companies into either ‘niche’ or ‘diversified’ innovators.
‘Geographic reach’ refers to the number of different countries each relevant patent is registered in. It reflects the breadth of geographic application intended, ranging from ‘global’ to ‘local’.

Johnson Matthey is a key player in the zeolites for exhaust filtering innovation area with 695 patents filed. The company engages in the production of zeolites for the selective catalytic reduction method of exhaust filtering. Johnson Matthey’s zeolites have excellent and varied filtration properties in addition to adsorption ability, which provides an advantage over costly, energy-intensive alternative separation methods such as distillation, absorption, and thermally driven separation processes. BASF, Toyota, and Aisin are some of the other key players.
