Chemistry and materials simulations speed clean energy production and storage
Catalysts are just one area of investigation for a multi-institutional team whose 70 publications in 3 years detail prodigious scientific output from the world's fastest chemistry simulations. "Our long-term goal is enabling the design of new generations of clean and sustainable technologies to produce, transmit, and store energy," said team leader Robert Harrison, a computational chemist at Oak Ridge National Laboratory.

Neutrons 'go viral' at ORNL
A research team from ORNL and North Carolina State University is using small angle neutron scattering to study how viruses change their structure when they move between different host species. Understanding how a virus reorganizes itself when it goes from a mosquito to a human is critical for the development of medicines that can block the spread of viruses.

Berkeley Lab scientist walks the walk -- produces more electricity than he consumes
Energy management engineer Steve Greenberg bikes three miles uphill to work every day, rain or shine. He refuses to use a desktop computer, insisting on a less energy-intensive laptop. And to avoid using paper towels each time he visits the bathroom, he keeps a hand towel in his office. Those are only a few of the things he does to reduce his carbon footprint—and that's just at work.

Supercomputers assist cleanup of decades-old nuclear waste
A research team led by Peter C. Lichtner of Los Alamos National Laboratory is using the Oak Ridge Leadership Computing Facility's Jaguar supercomputer, located at Oak Ridge National Laboratory, to build a 3-D model of an underground uranium waste plume at the Hanford Site's 300 Area. A better understanding of the underground migration properties of uranium, which has infiltrated the Columbia River, may aid stakeholders in weighing options for contaminant remediation.

NETL's green projects promise energy efficiency all year round
Forty years after the first Earth Day, it is almost second nature to toss a can or plastic bottle into the recycling bin, but being green is about much more than reusing materials. Just as individuals make a personal decision to "reduce, reuse, and recycle," businesses, industry, and other organizations are making the same commitment to being green.

Conference tackles interstate transmission
The US electricity grid is strained to its limit, and the nation's windiest and sunniest places are rarely near cities that generate high demand. Finding ways to string new power lines across several states is a challenge for even the most creative regulators and energy analysts determined to increase America's use of renewable energy.

Both directions at once
The challenge of controlling climate change is a goal that, to many, appears to be at odds with the equally important goal of energy security. However, the idea that the two goals are somehow mutually exclusive is not one accepted by ORNL energy researcher David Greene. "We don't want to sacrifice one for the other," he says. "We want -- and we believe it possible -- to achieve environmental goals and energy security goals at the same time.

DOE technology monitors CO2 injection in Australian gas field
Australia has launched the first carbon sequestration project in the southern hemisphere with the help of technology developed by researchers at the US Department of Energy. The Otway Basin Pilot Project will inject and monitor carbon dioxide in a depleted gas field in southeastern Australia to demonstrate the feasibility of storing the greenhouse gas in the Waarre Formation of the Otway Basin, and similar formations worldwide, to fight global climate change.

Cytochrome studies provide biofuel cell potential
Researchers from Pacific Northwest National Laboratory and collaborators have purified the protein called outer membrane cytochrome A (OmcA) from Shewanella oneidensis, a bacterium with promise for bioremediation of contaminants and the design of microbial fuel cells. They have measured its ability to bind and transfer electrons to mineral hematite, a solid ferric oxide. The team has shown that purified OmcA can directly reduce solid metals and that purified proteins are a next step in biofuel cell development.
