In September, the Department of Energy’s Oak Ridge National Laboratory (ORNL) announced successful efforts of the the lab’s Additive Manufacturing Integrated Energy (AMIE) demonstration. The nine-month project reached its goal of 3D-printing an alternative fuel vehicle and a paired building structure, both featuring the unique ability to power one another.
Thanks to R&D funding from the Energy Department’s Fuel Cell Technologies Office (FCTO), the Federal Express Hub at the Memphis International Airport in Tennessee has a new 15-vehicle fleet of hydrogen fuel cell powered ground support equipment. A ribbon-cutting ceremony was held on April 9 to mark the kickoff of the two-year demonstration of the vehicles, which are part of the world’s first zero-emissions ground support fleet in the world.
The average car uses more than 4,000 spot welds to hold its parts together. While manufacturers currently inspect the quality of welds by prying apart samples, Oak Ridge National Laboratory (ORNL) recently licensed a non-destructive technology that could check all welds in real-time on the production line. This new technology could make this process faster and more efficient, allowing vehicles to be safer and of a higher quality. Oak Ridge developed this technology through a research project supported by EERE’s Vehicle Technologies Office.
