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. We have proved that this technology can perform the functions of storage that we were looking for to help us manage the variability of wind energy on our operating system.

Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. Thus, further research is required to find better sodium host materials. Thus, further research is required to find better sodium host materials.

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

Researchers at the University of Texas, including Dr. 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 cell operates without a catalyst and has high storage efficiency. Credit: ACS, Lu et al. —Lu et al.

Energy Harvesting for Wearable Technology Steps Up

Cars That Think

But we do actually need that energy to be generated,” says Alper Bozkurt, who with Veena Misra codirects the Center for Advanced Self-Powered Systems of Integrated Sensors and Technologies (ASSIST) at North Carolina State University. Not least of those considerations is energy storage [and generation].”

New nanoparticle copper compound cathode could enable low-cost, long-life and high-power potassium-ion batteries for grid storage

Green Car Congress

At modest current densities, round-trip energy efficiencies of 99% can be achieved. Short-term transients, including those related to wind and solar sources, present challenges to the electrical grid. Existing energy storage technologies cannot satisfy these requirements. —Wessells et al. —Yi Cui.
