KNOXVILLE—One of the key holdups in the march toward more efficient sustainable energy could soon be answered, thanks in part to researchers at the University of Tennessee in Knoxville.

The College of Engineering’s Alexander Papandrew and Gerd Duscher are part of a broader Oak Ridge National Laboratory-led team that recently received a $2.75 million U.S. Department of Energy grant for work on improving fuel cells, $1.4 million of which went to their project.

The basic premise of their work is to find a far more efficient way to turn chemical energy—in this case natural gas—into electrical energy. [Read more…]

DOE’s ARPA-E announces 13 new projects at New York Energy Week

New York, N.Y.—ARPA-E Acting Director Cheryl Martin has announced $33 million in funding for 13 new projects aimed at developing transformational fuel cell technologies for low-cost distributed power generation.

The funding was announced Thursday at New York Energy Week. ARPA-E is Advanced Research Projects Agency-Energy in the U.S. Department of Energy.

The projects, which are funded through ARPA-E’s new Reliable Electricity Based on Electrochemical Systems, or REBELS, program, are focused on improving grid stability, balancing intermittent renewable technologies, and reducing CO2 emissions using electrochemical distributed power generation systems, a press release said.

Oak Ridge National Laboratory received $2.75 million for a project titled “Nanocomposite Electrodes for a Solid Acid Fuel Cell Stack.” [Read more…]

ORNL finding goes beyond surface of oxide films

Better batteries, catalysts, electronic information storage and processing devices are among potential benefits of an unexpected discovery made by Oak Ridge National Laboratory scientists using samples isolated from the atmosphere.

Researchers at the U.S. Department of Energy lab learned that key surface properties of complex oxide films are unaffected by reduced levels of oxygen during fabrication—an unanticipated finding with possible implications for the design of functional complex oxides used in a variety of consumer products, said Zheng Gai, a member of DOE’s Center for Nanoscale Materials Sciences at ORNL.

The findings are detailed in a paper published in Nanoscale. [Read more…]
