The heat is on for sodium-manganese oxide rechargeable batteries

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

By adding the right amount of heat, researchers have developed a method that improves the electrical capacity and recharging lifetime of sodium ion rechargeable batteries, which could be a cheaper alternative for large-scale uses such as storing energy on the electrical grid. Researchers at Pacific Northwest National Laboratory and Wuhan University in Wuhan, China used nanomaterials to make electrodes that can work with sodium, they reported June 3 online in the journal Advanced Materials.

Effect of cloud-scattered sunlight on earth's energy balance depends on wavelength of light

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

Atmospheric scientists trying to pin down how clouds curb the amount of sunlight available to warm the earth have found that it depends on the wavelength of sunlight being measured. This unexpected result will help researchers improve how they portray clouds in climate models.

Study: Algae could replace 17 percent of US oil imports

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

A new study shows that 17 percent of the United States' imported oil for transportation could be replaced by biofuel made from algae. Researchers also determined that the water needed to grow that algae could be substantially reduced by cultivating it in the nation's sunniest and most humid regions.

Getting to know the strong force, 1 of the 4 fundamental forces of the universe

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

In new work, high-energy physicists have observed two long-sought quantum states in the bottomonium family of sub-atomic particles. The result will help researchers better understand one of the four fundamental forces of the universe -- the strong force -- that helps govern the interactions of matter.

Upgrading the vanadium redox battery

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

Pacific Northwest National Laboratory researchers have discovered that the vanadium redox battery's performance can be significantly improved by modifying its electrolyte solution. The finding could improve the electric grid's reliability and help connect more wind turbines and solar panels to the grid.

Affordability of batteries key to harnessing wind and solar power

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

In a new report published in the journal Chemical Reviews, PNNL researchers say future batteries used by the energy grid to store power from the wind and the sun must be reliable, durable and safe, but affordability is key to widespread market deployment of these technologies.

Soot packs a punch on Tibetan Plateau's climate

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

New research shows that soot from industrial and agricultural pollution is landing on the Tibetan Plateau is causing snow to melt earlier on the plateau. As a result, India and China are experiencing wetter winters, drier summers and stronger monsoons.

Worldwide sulfur emissions rose between 2000-2005, after decade of decline

DOE/Pacific Northwest National Laboratory
Peer-Reviewed Publication

A new analysis of sulfur emissions shows that after declining for a decade, worldwide emissions rose again in 2000 due largely to international shipping and a growing Chinese economy. An accurate read on sulfur emissions will help researchers predict future changes in climate and determine present day effects on the atmosphere, health and the environment.
