Although more than 92,000 dams populate the country, the vast majority — about 89,000 — do not generate electricity through hydropower.
ORNL biogeochemist Elizabeth Herndon is working with colleagues to investigate a piece of the puzzle that has received little attention thus far: the role of manganese in the carbon cycle.
Oak Ridge National Laboratory researchers developed and demonstrated algorithm-based controls for a hybrid electric bus that yielded up to 30% energy savings compared with existing controls.
Researchers at Oak Ridge National Laboratory proved that a certain class of ionic liquids, when mixed with commercially available oils, can make gears run more efficiently with less noise and better durability.
It’s common knowledge that driving aggressively can dent gas mileage, but it’s difficult to determine exactly how much gas drivers waste. A new study by researchers at the Department of Energy’s Oak Ridge National Laboratory has quantified the impact speeding and slamming on the brakes has on fuel economy and consumption. They found that aggressive behavior behind the wheel can lower gas mileage in light-duty vehicles by about 10 to 40 percent in stop-and-go traffic and roughly 15 to 30 percent at highway speeds. This can equate to losing about $0.25 to $1 per gallon.
As a boy growing up in China, Xiaobing Liu knew all about Oak Ridge and the World War II Manhattan Project. He had no idea that he would one day work at DOE’s Oak Ridge National Laboratory, the Secret City’s successor. Liu is a lead researcher in geothermal heat pump (GHP) techn...
Oak Ridge National Laboratory researchers have produced the next generation of the National Hydropower Map – a visualization tool that provides updated statistics on overall capacity and performance on the nation’s hydropower fleet. The map is part of the lab’s National Hydropower ...
A 20-kilowatt wireless charging system demonstrated at the Department of Energy’s Oak Ridge National Laboratory has achieved 90 percent efficiency at three times the rate of the plug-in systems commonly used for electric vehicles today. This ability can help acc...
Plants and other biomass can be converted into a variety of renewable high-value products including carbon fibers, plastics, and liquid fuels such as ethanol and biodiesel that are beneficial for reducing petroleum use and vehicle emissions. Breaking down plants in order to release...
A research demonstration unveiled today at the Department of Energy’s Oak Ridge National Laboratory combines clean energy technologies into a 3D-printed building and vehicle to showcase a new approach to energy use, storage and consumption. The Additive Manufactur...
