Companies align to develop non-urea SCR system

LAKE FOREST, Ill -- Tenneco and GE Transportation have signed a joint agreement to develop a proprietary selective catalytic reduction (SCR) aftertreatment technology designed to reduce and control diesel engine emissions without the use of urea.

Both companies will collaborate on the development and production of GE's Hydrocarbon-Selective Catalytic Reduction catalyst technology (HC-SCR), a diesel aftertreatment innovation aimed at reducing harmful nitrogen oxide (NOx) emissions as effectively as urea-based SCR systems.

Tenneco will work with GE to further develop and integrate the HC-SCR technology for both the locomotive and off-highway vehicle markets. Once fully developed, the technology will also be offered to customers in the on-road, marine and stationary power markets.

Through an agreement with GE's Technology Ventures team, Tenneco has acquired licensing rights for GE's HC-SCR technology for on-road and off-highway vehicles, as well as other applications.

Earlier this year, Eaton also announced an agreement to use Clean Diesel Technologies' patented Advanced Reagent Injector System (ARIS) for injection of hydrocarbon fuel in emissions reduction applications, including Eaton's Aftertreatment System.
