Clingy Copper Ions Contribute to Catalyst Slowdown
Heavy-duty diesel trucks on the road today are equipped with aftertreatment systems that include selective catalytic reduction (SCR) technology using urea solution as a reducing agent to curtail harmful nitrogen oxide (NOx) emissions from engine exhaust before they reach the tailpipe. SCRs rely on a catalyst to help chemically convert NOx gases into nitrogen, water, and small amounts of carbon dioxide.
Like anything else subject to the laws of nature, catalysts-materials that help a desired reaction efficiently take place-tend to slow down the longer they are in use. Scientists at Pacific Northwest National Laboratory (PNNL), working with researchers at Washington State University and Tsinghua University, discovered a mechanism behind the decline in performance of an advanced copper-based catalyst. The team’s findings, featured on the cover of the journal ACS Catalysis, could aid the design of catalysts that work bette

A major pillar of the Biden Administration s Climate Week
announcements centered around the deployment of electric vehicles
(EVs). The Biden Administration has continued to emphasize the
deployment of EVs given the potential for significant reductions of
greenhouse gas (GHG) emissions in tandem with advancement of
American industry and workers.
The Climate Week announcements included actions from three
agencies: the U.S. Department of Transportation (DOT), U.S.
Department of Energy (DOE) and General Services Administration
(GSA). Respectively, the announcements were designed to support and

DETROIT, May 7, 2021 /PRNewswire/ American Axle & Manufacturing Holdings, Inc. (AAM), (NYSE: AXL) will receive $5 million in funding from the U.S. Department of Energy to advance development of its next generation Electric Drive Technology.
The cooperative agreement from the Office of Energy Efficiency and Renewable Energy (EERE) on behalf of the Vehicle Technologies Office is funding research projects in advanced batteries and electrification; advanced engine and fuel technologies, including technologies for off-road applications and alternative fueled engines; lightweight materials; new mobility technologies (energy efficient mobility systems) and alternative fuels technology demonstrations.
AAM will use the cooperative agreement funding to further the development of a low cost, high-performance, heavy rare earth-free 3-in-1 electric drive unit. AAM s 3-in-1 electric drive unit integrates power electronics with the electric motor and ge
Co-Optima FY20 report highlights advances in engines-fuels research
A report released this week highlights the most significant breakthroughs of the last year in the US Department of Energy’s (DOE) Co-Optimization of Fuels & Engines (Co-Optima) initiative, with details on findings that could translate into significant greenhouse gas (GHG) and tailpipe emissions reductions.
Co-Optima researchers are focused on identifying and understanding fuel components known as blendstocks, which can be produced from a wide spectrum of common domestic resources. These include renewable domestic biomass, such as forestry and agricultural waste, which can be combined with petroleum-based fuels to improve vehicles’ carbon footprint and engine performance.

Argonne is helping Caterpillar improve efficiency and reduce emissions in their heavy-duty diesel engines.
Heavy-duty diesel engines still power most large vehicles used in the construction, mining and transportation industries in the United States. Engineers are working to improve the fuel efficiency of these engines while minimizing pollution to reduce energy consumption and ensure the sustainability of these industries in the future.
