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.

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The present sodium-sulfur battery operates above 300 °C. A = lithium or sodium (Li or Na), M represents a metal and 1 ≤ n < z. —Lu et al.

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.
