ANN ARBOR—Nearly all of the studies used to promote biofuels as climate-friendly alternatives to petroleum fuels are flawed and need to be redone, according to a University of Michigan researcher who reviewed more than 100 papers published over more than two decades.
Once the erroneous methodology is corrected, the results will likely show that policies used to promote biofuels—such as the U.S. Renewable Fuel Standard and California's Low-Carbon Fuel Standard—actually make matters worse when it comes to limiting net emissions of climate-warming carbon dioxide gas.
U-M welcomes guest speaker Junmin Wang, Director Vehicle Systems and Control Laboratory, Ohio State University for a presentation on the importance and efficacy of control systems for current and future ground vehicles. In the ever-lasting efforts of reducing emissions, improving efficiencies, and enhancing safety for ground vehicles, importance of control systems has been growing rapidly due to the substantially elevated system complexities contributed by the fast technological advances in various relevant fields. This talk introduces a variety of vehicle system estimation and control research activities aiming towards clean, efficient, and safe ground transportation.
Frank Markus of Motor Trend magazine explains why every carbon molecule in a liquid biofuel, such as ethanol or biodiesel, can't be counted "as an ecological freebie." He reports on the debate about the Renewable Fuel Standard that took place during a panel discussion at this year's Society of Automotive Engineers (SAE) Government-Industry Meeting in Washington, DC.
At the close of this week's Asia Pacific Economic Cooperation (APEC) trade summit in Beijing, President Barack Obama and Chinese President Xi Jinping pledged to cut greenhouse gas emissions and detailed an agreement that includes a renewed five-year commitment to supporting clean vehicle research efforts via the U.S.-China Clean Energy Research Center.
The motor vehicle is at the cusp of being transformed by two threads of technology advancement. One is electrification, replacing gasoline and other liquid fuels with the direct use of electrons, enabling cars to plug in for some or all of their power. The other is intelligence, relieving humans of the error-prone task of driving through the connectivity, sensing and increasing automation, leading to vehicles that will one day drive themselves.
Officials from the U.S. Department of Energy, China’s Ministry of Science and Technology, faculty and students from the University of Michigan- led Clean Energy Research Center- Clean Vehicle Consortium (CERC-CVC) and industry partners met in Ann Arbor on August 11th and 12th to review progress on the initiative's joint clean vehicle energy research projects.
Transportation is one of several major sectors that contribute to climate change. Globally, the sector's 25% share of man-made carbon dioxide (CO₂) emissions is similar to its share of energy consumption. Because liquid fuels are so well suited for powering cars, trucks, boats and aircraft, transportation is uniquely reliant on oil, which is the natural resource most well suited for producing liquid fuels.
