New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

Researchers led by the Department of Energy’s Pacific Northwest National Laboratory (PNNL) have extended the capacity and duration of sodium-aluminum batteries. The new sodium-based molten salt battery uses two distinct reactions. of peak charge capacity.

New liquid alloy electrode significantly lowers operating temperature of sodium-beta batteries; improved performance

Green Car Congress

Researchers at Pacific Northwest National Laboratory (PNNL) have devised an alloying strategy that enables sodium-beta batteries to operate at significantly lower temperatures. The new electrode enables sodium-beta batteries to last longer, helps streamline their manufacturing process and reduces the risk of accidental fire.

Xcel Terms First Phase of Sodium-Sulfur Battery Wind Energy Storage Test Project Successful

Green Car Congress

Xcel Energy has released the preliminary results from its wind-to-battery (W2B) storage project in Minnesota, and termed the technology successful. In October 2008, Xcel began testing a one-megawatt sodium-sulfur (NaS) battery ( earlier post ) to demonstrate its ability to store wind energy and move it to the electricity grid when needed.

Iowa State/Ames Lab researcher receives $3M from ARPA-E for solid-state sodium battery

Green Car Congress

The Advanced Research Projects Agency - Energy (ARPA-E) has awarded $3 million from its 2015 OPEN funding to a project to develop an all-solid-state sodium battery. A sodium-based battery, on the other hand, has the potential to store larger amounts of electrical energy at a significantly lower cost. Led by Steve W.

DOE awards Cummins $5M for automation of electrolyzer cell and stack assembly

Green Car Congress

Proton exchange membrane (PEM) electrolyzers use a solid polymer electrolyte, and alkaline electrolyzers use an electrolyte solution, such as potassium hydroxide or sodium hydroxide mixed with water. When any type of electrolyzer is powered by renewable energy sources, such as wind, solar or hydro, it produces “green” hydrogen.
