In order to study how salmon are affected by swimming through hydroelectric dams, scientists have traditionally equipped them with surgically-implanted acoustic tracking tags. Now, however, a team has developed a much lighter acoustic tag, that can be injected into fish using a needle.

Migrating salmon in the Pacific Northwest are set to be helped on their journey by Sensor Fish. Developed by PNNL, these devices record and analyze the physical stressors faced by the fish on their trek and provide hydroelectric dams with data to become more fish-friendly.

American offshore wind energy is set to be studied in depth at two potential sites courtesy of some advanced data measurement buoys that will examine, for example, how powerful winds are at typical turbine blade heights of up to 600 feet above the ocean.

The US Department of Energy's Pacific Northwest National Laboratory has developed a smartphone attachment, that turns the phone into a 1,000x microscope. What's more, it's made from less than one dollar's worth of material.

A new battery electrode designed at the Pacific Northwest National Laboratory (PNNL) combines liquid-state cesium and sodium to dramatically improve on the efficiency, safety and useful life of sodium-beta batteries (NBBs).

Researchers from the Pacific Northwest National Laboratory (PNNL) have designed a new type of anode that increases lithium-sulfur battery-life by four times, bringing the technology closer to maturity.

In order to better understand and protect wild stocks of salmon, it's necessary to track their whereabouts using implanted acoustic tags. Scientists are now improving those tags, by developing batteries that have both a smaller size and higher energy density than conventional fish tag batteries.

Engineers at the Department of Energy’s Pacific Northwest National Laboratory (PNNL) have created a continuous process that produces useful crude oil minutes after harvested algae is introduced. The final product of this process can be refined into aviation fuel, diesel, or gasoline.

Department of Energy's Pacific Northwest National Laboratory is developing a hybrid solar/gas system that converts natural gas power plants into hybrid solar/gas power plants.

A new, small-scale solid oxide fuel cell (SOFC) system that boasts a record efficiency of up to 57 percent could be used for household and neighborhood power generation.

The Department of Homeland Security’s (DHS) Science and Technology Directorate (S&T) has created a giant inflatable plug designed to contain flooding or dangerous gases in mass transit tunnels.

Scientists have determined the molecular structure of proteins that allow bacteria cells to transfer electrical charge, which could be a big step towards more efficient microbial fuel cells.
