28-Mar-2008 US Department of Energy to provide up to $2.4M to advance solar energy in 12 US cities
US Department of Energy Secretary Samuel W. Bodman today announced that DOE will make available up to $2.4 million to 12 cities across the country selected as Solar America Cities, chosen for their commitment and comprehensive approach to the deployment of solar technologies and the development of sustainable solar infrastructures. These projects further President Bush's Solar America Initiative, which aims to make electricity from solar photovoltaics cost-competitive with conventional electricity by 2015.
29-Feb-2008 US Department of Energy welcomes the UK as 21st member of the Global Nuclear Energy Partnership
The US Department of Energy today welcomed the United Kingdom as the Global Nuclear Energy Partnership's twenty-first partner. GNEP, a voluntary international partnership, aims to safely and securely expand nuclear power worldwide while responsibly managing nuclear waste and reducing proliferation risks. US Energy Secretary Samuel Bodman met with UK Secretary of State for Business, Enterprise and Regulatory Reform, Rt. Hon. John Hutton prior to the UK signing the GNEP Statement of Principles in Washington, DC.
31-Jan-2008 Spin in the neutron
Physicists were in a whirl after measurements in the '80s revealed that the spins of the individual building blocks of the proton don't add up to the proton's actual spin. The so-called "proton spin crisis" spurred efforts to pin down where protons -- and neutrons -- get their spin. Pioneering measurements in Jefferson Lab's Hall A have opened the door for measuring some suspected sources of the neutron's spin.
15-Jun-2007 Discovering the details of dissolution
Ions in a liquid are like celebrities at a movie opening -- surrounded by fans who jostle each other to get as close as the velvet ropes around the red carpet will allow. So it is
with ions in water or other liquids or solvents.
15-Jun-2007 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.
15-Jun-2007 Dust in the wind
In March 2006, a major dust storm
occurred in Niamey, Niger. Although a
common occurrence, this was the first
time both satellite- and ground-based
instruments were used simultaneously
to assess the impact of airborne Saharan
dust on incoming and outgoing solar
15-Jun-2007 On thin icege/gi
Thin clouds high in the upper troposphere, like cirrus clouds, may have a significant influence on Earth's climate and enhance the "greenhouse effect" by absorbing more of
the sun's radiation than they take in. Unknown is how ice crystals in these clouds absorb and reflect radiant energy and enhance the amount of radiant energy emitted toward the earth's surface.
5-Apr-2007 Science and Technology Facility is first LEED Platinum Federal Building
A research facility at the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory has been designated as one of the most energy efficient and environmentally friendly places to work in the United States by the U.S. Green Buildings Council under its Leadership in Energy and Environmental Design (LEED) Green Building program.
22-Mar-2007 Sailing for science
When most people think of an ocean
cruise, they think of buffets and relaxing
in deck chairs. For Pacific Northwest
National Laboratory researcher Philip
Long, an expedition cruise aboard the
Joint Oceanography Institutes Deep
Earth Sampling (JOIDES) Resolution
research vessel meant 12-hour workdays
examining ocean floor core samples for
22-Mar-2007 Carbon capture made easy
Gasification plants may be one
of the keys to a hydrogen economy,
if capture and sequestration of carbon
dioxide (CO2) becomes technically
and economically feasible. These plants
would transform fossil fuel feedstock,
including coal, biomass and municipal
wastes, into clean-burning hydrogen
gas where the only byproduct is water.
1-Dec-2006 Nuclear energy and the 21st century
The world is entering a period of renewed interest and
growth in nuclear energy, driven by rising oil prices, growing
demand for electricity, new passively safe plant designs, and
low emissions of greenhouse gases, which some governments
need to meet Kyoto Protocol standards. The Kyoto Protocol
assigns mandatory targets for reducing greenhouse gas
emissions to signatory nations.
29-Nov-2006 Moving grid operations from minutes to seconds
In the last century, the electric power grid has grown from a
system that served one square mile in New York into a highlycomplex
interconnected system that serves all of North America.
Initially, individual local systems would connect to each
other to share resources and increase reliability.
29-Nov-2006 Coal: An energy bridge to the future
For years, coal drove the transportation business in this country, and it may be poised for a comeback. A hundred years ago, steam engines burned tons of coal as they
pulled trains across the country. Now researchers are looking at converting that coal to liquid fuel to fill our gas tanks and move cars and trucks.
20-Nov-2006 Fuel cell prototypes exceed expectations
Fuel prices continue to rise. However, one solution -- fuel cells -- is gaining on that problem. The Solid State Energy Conversion Alliance (SECA) has achieved the first of a threepart goal: developing solid oxide fuel cell systems that reduce fuel cell production costs by a factor of ten.
17-Nov-2006 Technology improves food processing quality
Researchers at Pacific Northwest
National Laboratory have developed an
ultrasonic technology that could tell
food manufacturers if foreign objects
have fallen into their product long
before it reaches the consumer.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
