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 for various transportation and other applications.

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 into complete aftertreatment systems 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.

Tenneco will also have the opportunity to develop GE's HC-SCR technology for expanded 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, marine and stationary power applications and certain locomotive fields of use.

The two companies also announced that Tenneco has been awarded a development contract for locomotive projects and is positioned to become a long-term strategic supplier of diesel aftertreatment solutions to GE Transportation.

The GE HC-SCR technology is expected to provide advantages in weight, packaging, and convenience, in addition to being offered as an alternative to a urea-based SCR technology. Tenneco currently offers its own innovative ELIM-NOx urea-based SCR aftertreatment solutions for commercial on and off-road vehicle customers.
