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.
