A new, patented catalyst developed by scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory that can reliably and economically reduce between 95 percent and 100 percent of the nitrogen oxide (NOx) emissions from diesel fueled engines has been licensed to Integrated Fuel Technologies, Inc. (IFT), a Kirkland, Wash.-based start-up company.

IFT plans to integrate the technology – named Diesel DeNOx Catalyst – into the firm's existing products that reduce emissions of other greenhouse gases that could be sold to original equipment manufacturers (OEM), said IFT president Robert Firebaugh.

'OEMs have expressed an interest in IFT products enhanced with the Diesel DeNOx Catalyst,' Firebaugh said. 'These companies want to know if the technology can survive continuous testing,' he said.

'The catalyst can also be easily retrofitted for installation on existing diesel engine vehicles,' said Christopher Marshall, the Argonne chemist who led the development of technology, adding that 'there is a potentially large pool of customers for this technology, given the 11-million diesel engines currently on the road.'

Emissions of NOx are regulated by U.S. Environmental Protection Agency (EPA), which began implementing on Jan. 1, 2007 a more stringent regulation to reduce releases of the smog-causing greenhouse gas by 2.6 million tons a year on a phased-in basis through 2010. Standards set by the California Air Resource Board (CARB) are strictest in the United States. Argonne and IFT aim for the Diesel DeNOx technology to meet CARB standards.

IFT is also collaborating with Argonne under a two-year Work-For-Others agreement to test the technology's longevity in real-world use and to demonstrate it in real world applications to determine if it can meet a broad array of transportation applications.
