Off-shore Power Potential Floating in the Wind
Results: Two bright yellow buoys - each worth $1.3 million - are being deployed by Pacific Northwest National Laboratory in Washington State's Sequim Bay. The massive, 20,000-pound buoys are decked out with the latest in meteorological and oceanographic equipment to enable more accurate predictions of the power-producing potential of winds that blow off U.S. shores. Starting in November, they will be commissioned for up to a year at two offshore wind demonstration projects: one near Coos Bay, Oregon, and another near Virginia Beach, Virginia.
Transformations: Future Challenges for Catalytic Vehicle Emission Control, Industrial Catalyst Developer at National Lab, Why Bio-oil Turns to Gunk
In the latest edition of the Institute for Integrated
catalysis scientist Chuck Peden describes past, present, and future research on abatement of
harmful compounds in vehicles and other sources. Alongside the many successes
are new challenges for scientists developing catalytic emission control
applications. Also, meet Hai-Ying Chen, a catalysis developer at Johnson
Matthey, who recently completed a 9-week fellowship at Pacific Northwest
National Laboratory—a great example of bringing industry and a national lab
together to work on clean energy.

More Haste, Less Waste
Results: Mirroring the climate using ones and zeros takes a lot of computing power. Scientists at Pacific Northwest National Laboratory found a way to reduce that power hungry need dramatically with a novel computational approach. Replacing a single long computer drive with multiple short runs, they found a way to get more mileage out of the largest and fastest supercomputer systems and get the climate answers hundreds of times faster. The new strategy provides equally reliable results but at a fraction of the computational cost.
Ben Kravitz Quoted in IOP News Blog for Geoengineering Work on Climate Change
Dr. Ben Kravitz, a postdoctoral researcher in atmospheric sciences at Pacific Northwest National Laboratory, was quoted in environmentalresearchweb
, the IOP community website on his recent solar geoengineering paper. Discussing the publication in Environmental Research Letter
, "A multi-model assessment of regional climate disparities caused by solar geoengineering
," the article quoted lead author Kravitz on the concerns of solar geoengineering used to offset the warming of the climate and some examples of the tradeoffs that could arise across different regions. The takeaway: solar geoengineering alone is not the answer to slowing climate warming, but depending on the regional needs geoengineering can offset some of the effects. "If society continues to increase carbon dioxide emissions and offsets the climate change with geoengineering, we would need to do continually more geoengineering to keep up with increasing emissions," said Kravitz.
As Light Dims and Food Sources Are Limited, Key Changes in Proteins Occur in Cyanobacteria
Results: Using a targeted chemical
biology approach, scientists at Pacific Northwest National Laboratory (PNNL) identified
an important subset consisting of more than 300 proteins in a bacterium adept
at converting carbon dioxide into other molecules of interest to energy
researchers. These proteins are involved in generating macromolecule synthesis
and carbon flux through central metabolic pathways and may also be involved in
cell signaling and response mechanisms.

Profiling Plumbs Hidden Depths
." The article features the Wright-led study
on profiling functional enzymes in the lysosomes of living cells. Because of
the lysosome's role in fighting diseases, this work provides insights relevant
to the progression of neurodegenerative conditions and other diseases. The
study by Susan Wiedner, Lindsey Anderson, Natalie Sadler, William Chrisler,
Vamsi Kodali, Richard Smith, and Aaron Wright appears in Angewandte Chemie

American Catalysis Society Conference, held in Kentucky last year.
Taking Back the Angels' Share of Atoms
Results: On the surface of a
battery's electrode, a material that stores wind energy, or on nearly any other
surface, scientists can use atom probe tomography to identify and locate almost
every atom. But some atoms evaporate non-uniformly before they are identified -- reminiscent
of the angels' share, the amount of wine or whiskey volume lost to evaporation
during barrel aging. Scientists at Pacific Northwest National Laboratory (PNNL) and
the University of Rouen revealed which atoms evaporate in mixed materials,
where there are many different types of atoms. They managed this feat by
correlating data from three techniques, accounting for all of the atoms and determining
how atoms were evaporating from APT.
