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 methane hydrate.

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.

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.

PNNL's building sciences -- From concept to commercialization
The Department of Energy has a new vision for residential and commercial buildings in the United States -- net-zero energy buildings that will produce as much energy as they consume.

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.

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.

PNNL positioned to meet nation's energy challenges
Innovative science and technological advances will play a key role in solving the energy challenges facing the United States, and PNNL stands ready to help.

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.

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.

17-Nov-2006
Uniform nano-clusters signal improved catalysts
A new model system of nanostructures has been synthesized and could lead to control of chemical transformations critical for enhancing the nation's energy future.

16-Nov-2006
Sometimes smaller is better
A research team from the Pacific Northwest National Laboratory, Oregon Health and Science University, University of Minnesota and the University of Idaho is studying the ability of nanoscale iron particles to reduce carbon tetrachloride, a common groundwater contaminant.

Department of Energy advances commercialization of climate change technology
U.S. Department of Energy (DOE) Assistant Secretary Jeffrey D. Jarrett has announced the Department's support of seven tests in North America to advance carbon sequestration technologies while attending the Asia-Pacific Partnership on Clean Development and Climate.

US wind power industry tempers its 2006 forecast slightly
The American Wind Energy Association (AWEA) announced on October 24th that the U.S. wind energy industry remains on track to set a record for wind power installations this year, with U.S. wind generating capacity increasing by 2,750 megawatts (MW).

23-Oct-2006
DOE/EPA release top fuel economy lists for 2007 models
The U.S. Department of Energy (DOE) and the U.S. Environmental Protection Agency (EPA) today released the 2007 Fuel Economy Guide to help consumers make well-informed choices when purchasing new vehicles.

DOE's Solar Decathlon draws student teams worldwide
They come from around the world to participate in the Solar Decathlon, a contest focused on creating a livable, solar-powered house on a shoe-string budget.

Hypernuclei at Jefferson Lab
In 1827, Robert Brown observed that pollen grains floating in a drop of water jiggled constantly. The phenomenon became known as Brownian motion. Over 75 years later, Einstein proposed that the pollen grains were being jostled by the molecules of water. The impurity (pollen grains) Brown had added to the water allowed Einstein to deduce the presence of individual water molecules and describe at least one of their properties.

Pocket-sized physics detector does big science
How do quarks and gluons, the elementary constituents of all matter, combine to form the protons and neutrons in the nucleus of the atom? This is a fundamental unsolved question in nuclear physics that researchers at Jefferson Lab are working to answer. The internal structure of the proton has been studied for several decades, and scientists have learned a great deal. However, much less is known about the structure of the neutron.

Spin structures of protons and neutrons
Just as a top spins on a table, the tiny quarks inside protons and neutrons also spin. Now a complex calculation by theoretical nuclear physicists at Jefferson Lab has revealed that a quark's spin may be altered by the surroundings of the proton or neutron in which it resides. This surprising result, recently published in the journal, Physical Review Letters, may lead to new insights about how ordinary matter is constructed.

On the leading edge
The Accelerator Division's Institute for Superconducting Radiofrequency (SRF) Science & Technology is a world leader in SRF accelerator technology research and design. Now the newest idea out of the Institute may revolutionize the way accelerating cavities are produced -- making the manufacturing process faster and cheaper, while producing cavities that could potentially outperform any other niobium cavities ever tested.

Big Bite does its stuff
Jefferson Lab's core mission is to study the heart of ordinary matter: the nucleus of the atom. Now Hall A has a new magnet and detector system designed to help physicists look at the nucleus in a whole new light. "BigBite" has debuted in its first experiment at Jefferson Lab.

G-Zero update
In research performed in Hall C, nuclear physicists have found that strange quarks do contribute to the structure of the proton. This result indicates that, just as previous experiments have hinted, strange quarks in the proton's quark-gluon sea contribute to a proton's properties. The result comes from work performed by the G-Zero collaboration, an international group of 108 physicists from 19 institutions, and was presented at a Jefferson Lab physics seminar on June 17.

"Smart" energy devices + real-time pricing = increased options for consumers
About 200 volunteers in the Pacific Northwest are testing equipment that is expected to make the power grid more reliable while offsetting huge investments in new transmission and distribution equipment. Pacific Northwest National Laboratory recently launched the Pacific Northwest GridWise^TM Testbed Demonstration, a regional initiative to test and speed adoption of new smart grid technologies that can make the power grid more resilient and efficient.
