Argonne-led project to connect capital region cities, build electrification ecosystem
The U.S. Department of Energy’s (DOE) Office of Energy Efficiency and Renewable Energy (EERE) is blazing a path to broaden the appeal of electric vehicles. The EERE has awarded DOE’s Argonne National Laboratory $139 million for 55 projects focused on advancing the electrification of transportation and charging electric vehicles (EVs).
One of the projects — a three-year EERE grant for the development of a regional ecosystem for the District of Columbia and surrounding states — will enable EVs of all sizes to be used by fleets, transportation network companies and consumers. The ecosystem will be designed to connect the capital region’s cities with EV corridors, permit charging at multimodal hubs and logistics centers, and increase the attractiveness and profile of electric transportation. It will also be developed with a goal of addressing social equity issues in neighborhoods near these hubs and within cities and towns.
Argonne energy scientists will simulate the charging infrastructure demand to satisfy the rising EV adoption, analyze costs and emissions to quantify expected benefits from electric chargers and vehicles and help promote the electrification ecosystem. They will also collaborate with Argonne environmental scientists to model energy resources in the study area.
Photon source helps identify how meteorite strikes affect planet Earth
Researchers led by Staff Scientist Sally June Tracy at the Carnegie Institution for Science, Washington, D.C., used the capabilities of Argonne’s Advanced Photon Source (APS) to learn more about how quartz transforms when struck by meteorites, and how such impacts affect the geological makeup of planets.
Tracy and her colleagues — Princeton University Professor Thomas Duffy and Washington State University senior scientist Stefan Turneaure — found a new crystal structure of quartz, one that lasts only about 100 nanoseconds after impact. The team analyzed the atomic-level changes that occurred in the quartz’s structure at the very moment of impact.
At the APS’ Dynamic Compression Sector, the team was able to capture the moment of impact on a quartz sample, taking snapshots of its structure at extremely short timescales. Researchers used a hydrogen gas gun to fire a projectile at the quartz, then used an X-ray beam to probe the changes the quartz underwent in the nanoseconds during and after impact. The APS is a U.S. Department of Energy Office of Science User Facility.
