Byproducts from biofuel focus of PNNL and WSU partnership
Researchers at the Department of Energy's Pacific Northwest National Laboratory have created a continuous thermo-chemical process that produces useful biocrude from algae. The process takes just minutes and PNNL is working with a company which has licensed the technology to build a pilot plant using the technology.

Energy technologies get a boost toward commercial use
Six energy technologies that do everything from protect fish to monitor the health of flow batteries are getting a boost at the Department of Energy's Pacific Northwest National Laboratory.DOE is awarding PNNL nearly $1.5 million to bring six technologies closer to commercial use. The projects were announced today by DOE's Office of Technology Transitions, which selected them for funding from its Technology Commercialization Fund. The technologies show great promise, but need further development to improve their potential use in commercial products or services.

Night vision for bird- & bat-friendly offshore wind power
The same technology that enables soldiers to see in the dark can also help protect birds and bats near offshore wind turbines.Night vision goggles use thermal imaging, which captures infrared light that's invisible to the human eye. Now, researchers at the Department of Energy's Pacific Northwest National Laboratory are using thermal imaging to help birds and bats near offshore wind farms. PNNL is developing software called ThermalTracker to automatically categorize birds and bats in thermal video. Birds and bats fly over offshore waters, but they're difficult to track in such remote locations.

Battery500's first seedling projects awarded nearly $6 million
The advanced batteries that will power tomorrow's electric vehicles are closer to being a reality thanks to more than $5.7 million in funding awarded to 15 different projects through the Department of Energy's Battery500 consortium.The new projects are the first to be funded through the consortium, which is led by DOE's Pacific Northwest National Laboratory and involves multiple partners at universities and other national labs. The new seedling projects were announced July 12 as part of a larger unveiling of a total of $19.4 million in new DOE funding for vehicle technologies research.

Scientists bear witness to birth of an ice cloud
RICHLAND, Wash. – Scientists have witnessed the birth of atmospheric ice clouds, creating ice cloud crystals in the laboratory and then taking images of the process through a microscope, essentially documenting the very first steps of cloud formation.

Nature and the Nurture of Aerosols
You've seen it when flying into major cities the world over: a haze over the city. It is caused by aerosol particles, but scientists don't know all the details of the complex chemistry involved. At Pacific Northwest National Laboratory, Dr. Alla Zelenyuk and her team took on a specific part of that haze: originated from isoprene. After being released by the trees and shrubs, isoprene reacts in the atmosphere and becomes assorted chemicals, including IEPOX (isoprene epoxydiols). The team found that IEPOX is a major player in producing aerosols from isoprene and that particle size, certain coatings, and acidity influence how IEPOX behaves.

Love that fresh smell after a rain?
Most of us think of that sweet smell after a storm as the aftereffect of rain that has rinsed the air of pollutants and dust. But it turns out that rain also triggers the release of a mist of particles from wet soils into the air, a finding with consequences of its own for how scientists model our planet's climate and future.The evidence comes in the form of tiny glassy spheres, less than one-hundredth the width of a human hair, discovered at the Great Plains of Oklahoma after a rainstorm and put under scrutiny by scientists at several U.S. Department of Energy facilities. The study appears May 2 in Nature Geoscience.According to the authors, scientists have largely assumed that organic particles from the soil enter the air through erosion by wind or through agricultural work. The effects of rain splash haven't been part of the discussion.But the team's field observations indicate that up to 60 percent of particles that are airborne after a rainstorm in certain areas, such as grasslands and tilled fields, come from the soil. These organic particles are carbon-based and come from decaying vegetation and organisms. The tiny bits of organic matter can hold tremendous sway over our climate, playing a role in the fate of sunlight as it hits Earth.Authors of the study are from two DOE Office of Science user facilities — EMSL, the Environmental Molecular Sciences Laboratory at the Pacific Northwest National Laboratory, and the Advanced Light Source at Lawrence Berkeley National Laboratory — as well as the Berkeley Lab and the University of Massachusetts at Amherst.Chemist Alexander Laskin led the team at PNNL and chemical scientist Mary Gilles led the group at the Berkeley Lab.

Abundant natural gas will not slow climate change according to new study
A new analysis of global energy use, economics and the climate shows that without new climate policies, expanding the current bounty of inexpensive natural gas alone would not slow the growth of global greenhouse gas emissions worldwide over the long term, according to a study appearing today in Nature Advanced Online Publication. Because natural gas emits half the carbon dioxide of coal, many people hoped the recent natural gas boom could help slow climate change — and according to government analyses, natural gas did contribute partially to a decline in U.S. carbon dioxide emissions between 2007 and 2012.
