Through a consortium of Department of Energy national laboratories, Oak Ridge National Laboratory scientists are applying their expertise to provide solutions that enable the commercialization of emission-free hydrogen fuel cell technology for heavy-duty vehicles, or HDV. As a viable alternative to internal combustion engines powered by gasoline, hydrogen fuel cells can provide sustainable, clean energy with a comparable user experience.
“Adoption of hydrogen technology in the HDV market could prove to be the breakthrough launching widespread use,” said ORNL’s David Cullen, a scientist in the Center for Nanophase Materials Sciences who studies fuel cell catalysts and electrode structures using advanced microscopy and
DOE Issues $162 Million in Funding to Reduce Carbon Emissions in Vehicles

The US Department of Energy (DOE) today unveiled two funding opportunities totaling more than $162 million to improve efficiency and reduce carbon emissions among cars, trucks, and off-road vehicles. The funding will support the next stage of the SuperTruck initiatives, which is aimed at electrifying freight trucking, along with efforts to expand electric vehicle (EV) infrastructure and lower emissions for on- and off-road vehicles.
As Environment + Energy Leader recently reported, building a clean energy economy to address the climate crisis is a top priority of the Biden Administration, and the transportation sector will play a critical part in the effort. Transportation accounts for approximately 30% of total US energy needs and generates the largest share of the country’s greenhouse gas emissions. DOE’s new funding seeks to address the two largest contributors to transportation

Mapping Performance Variations to See How Lithium-Metal Batteries Fail
Using high-energy x-rays, scientists probed different points across a high-energy-density lithium-metal battery of interest for long-range electric vehicles and used the data to identify the main failure mechanism

UPTON, NY Scientists have identified the primary cause of failure in a state-of-the-art lithium-metal battery, of interest for long-range electric vehicles. Using high-energy x-rays, they followed the cycling-induced changes at thousands of different points across the battery and mapped the variations in performance. At each point, they used the x-ray data

The U.S. Department of Energy (DOE) has announced two new funding opportunities, totaling more than $162 million, “to improve efficiency and reduce carbon emissions among cars, trucks, and off-road vehicles”.
The programs comprise the SuperTruck 3 funding opportunity and the Low Greenhouse Gas Vehicle Technologies (LGGVT) funding opportunity. As part of the SuperTruck 3 prize, the DOE Office of Energy Efficiency and Renewable Energy’s (EERE) Vehicle Technologies Office (VTO) and Hydrogen and Fuel Cell Technologies Office are partnering to offer up to $100 million in funding over four years. This funding will go towards pioneering electrified medium- and heavy-duty trucks and freight system concepts that achieve higher efficiency and lower emissions, the DOE outlined. EERE ini
