The U.S. Department of Energy's National Renewable Energy Laboratory and Argonne National Laboratory this week announced the release of the Transportation Energy Futures study, an assessment of avenues to reach deep cuts in petroleum use and greenhouse gas emissions in the transportation sector. The project suggests opportunities for 80% reductions by 2050
President Barack Obama is pushing Congress to authorize more federally funded research into clean energy technologies that can wean automobiles off oil. Obama proposed the idea of an energy security trust last month in his State of the Union address, but he was putting a price tag on the idea during a trip Friday to the Argonne National Laboratory outside Chicago—$2 billion over 10 years.
A technology that will allow widespread adoption of plug-in electric vehicles without negatively impacting the electrical grid is the subject of a commercial license agreement between Battelle and AeroVironment, Inc., of Monrovia, Calif. The technology may also ultimately result in lower costs for plug-in electric vehicle owners.
Ford is joining with Daimler and Renault-Nissan to speed development of cars that run on hydrogen, with hopes of bringing a vehicle to market in as little as four years. Hydrogen fuel cell vehicles generate electricity after a chemical reaction between hydrogen and oxygen. Hydrogen is stored in special high-pressure tanks, and the only emissions are water vapor and heat.
The argument that those who have fuel-efficient cars drive them more and hence use more energy is overplayed and inaccurate, a University of California, Davis economist and his co-authors say in a comment article published in Nature.
University of California, Santa Barbara researchers debate which makes more sense, growing fuel crops to supply alternative-fuel vehicles with ethanol and other biofuels or using photovoltaics to directly power battery electric vehicles?
The U.S. Department of Energy's National Renewable Energy Laboratory has created an energy analysis tool to help individuals and educators experiment with future energy use scenarios. The interactive Buildings, Industry, Transportation, Electricity, and Transportation Scenarios (BITES) allows users to explore how changes in energy demand and supply can impact carbon dioxide emissions and the current U.S. energy trajectory.
Norfolk Southern Railway No. 999 is the first all-electric, battery-powered locomotive in the United States. But when one of the thousand lead-acid batteries that power it dies, the locomotive shuts down. To combat this problem, a team of Penn State University researchers is developing more cost-effective ways to prolong battery life.
A new study of the batteries commonly used in hybrid and electric-only cars has revealed an unexpected factor that could limit the performance of batteries currently on the road. Researchers led by Ohio State University engineers examined used car batteries and discovered that over time lithium accumulates beyond the battery electrodes—in the "current collector," a sheet of copper which facilitates electron transfer between the electrodes and the car's electrical system.
As plug-in electric vehicles become an ever-more central part of America's daily life, University of Notre Dame researchers are anticipating what that development will mean for the nation's power grid. Under funding from the National Science Foundation's Cyber-Physical Systems Program, a research group is attempting to develop mathematical algorithms to help guide the integration of plug-in hybrid electric vehicles into the power grid.
Fuel economy of all new vehicles sold in the United States remains at its highest level ever, while emissions are at a record low, say researchers at the University of Michigan Transportation Research Institute.
Researchers from the Georgia Institute of Technology are partnering with GE and Ford Motor Co. to study ways to add greater efficiencies to electric driving and charging performance.
As fuel economy of new vehicles improved 18% over the past five years, billions of gallons of gas and billions of pounds of emissions have been saved, say University of Michigan researchers. To reach these results, the researchers collected fuel data on 61 million new cars, pickup trucks, minivans, and SUVs sold in the U.S. since 2007.
Engineering students and staff at the University of Birmingham have designed and built a prototype hydrogen-powered locomotive, the first of its kind to operate in the U.K. The narrow gauge locomotive is a hybrid design, combining a hydrogen fuel cell and lead acid batteries similar to the ones used in cars.
Washington University in St. Louis recently landed a $2 million U.S. Dept. of Energy grant with $1.2 million in matching funds from the university to design a battery management system for lithium-ion batteries that will guarantee their longevity, safety and performance. The development is geared toward electric vehicle technologies.
For the second straight month, fuel economy of all new vehicles sold in the United States fell by 0.2 mpg—likely reflecting a slight drop in gas prices, say researchers at the University of Michigan Transportation Research Institute.
As the United States' natural gas reserves have sparked an interest in natural gas-powered vehicles, Argonne National Laboratory is hoping to use its automotive research facilities to lead the way in natural-gas vehicle testing.
Gasoline prices this summer could stay relatively steady provided that an already-tense Middle East doesn't flare up and nothing else happens to disrupt supplies, a Purdue University economist says.
A new study by civil engineers at Massachusetts Institute of Technology shows that using stiffer pavements on the nation's roads could reduce vehicle fuel consumption by as much as 3%—a savings that could add up to 273 million barrels of crude oil per year, or $15.6 billion at today's oil prices. This would result in an accompanying annual decrease in carbon dioxide emissions of 46.5 million metric tons.
The first 3D-printed car body may set the pace for a new mode of manufacturing.
Fuel economy of all new vehicles sold in the United States has topped 24 mpg for the first time ever, say researchers at the University of Michigan Transportation Research Institute.
Airbus, Boeing, and Embraer signed a Memorandum of Understanding to work together on the development of drop-in, affordable aviation biofuels. The collaboration agreement supports the industry's multi-pronged approach to continuously reduce the industry's carbon emissions.
Tomorrow's aircraft could contribute to their power needs by harnessing energy from the wheel rotation of their landing gear to generate electricity. They could use this to power their taxiing to and from airport buildings, reducing the need to use their jet engines. This would save on aviation fuel, cut emissions, and reduce noise pollution at airports.
As the United States transitions away from a primarily petroleum-based transportation industry, a number of different alternative fuel sources—ethanol, biodiesel, electricity, and hydrogen—have each shown their own promise. Hoping to expand the pool even further, researchers at Argonne National Laboratory have begun to investigate adding one more contender to the list of possible energy sources for light-duty cars and trucks: Compressed natural gas.
A Stanford University research team has designed a high-efficiency charging system that uses magnetic fields to wirelessly transmit large electric currents between metal coils placed several feet apart. The long-term goal of the research is to develop an all-electric highway that wirelessly charges cars and trucks as they cruise down the road.
