WASHINGTON, D.C. — The U.S. EPA updated its list of emerging technologies for meeting engine emissions reduction goals to include three new urea-based, selective catalytic reduction systems.

The manufacturers and products are: Nett Technologies Inc’s BlueMAX 200 for on-highway, non-EGR, 1994-2006 heavy heavy-duty diesel engines; Johnson Matthey’s SCCRT for on-highway, EGR and non-EGR, 2002-2006 heavy-duty diesel engines and; Engine Control Systems’ TermiNOx D, for on-highway, EGR and non-EGR, 1998-2006 heavy heavy- and medium heavy-duty diesel engines.

Both Johnson Matthey and Nett Technologies now have two SCR systems listed as emerging technology and have several products listed as verified technology. Engine Control Systems obtained its first emerging technology listing.

The emerging technologies may be used in any clean diesel grant program as of this spring. They have one year to obtain full verification by the EPA to be added to the verified technology list.
