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. The rise of renewable solar and wind power is demanding sustainable storage technologies using components that are inexpensive, Earth-abundant and environmental friendly.

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.

Mitsubishi and Tokyo Institute of Technology Developing EV Smart Charging from Wind Turbines

Green Car Congress

and the Tokyo Institute of Technology are developing a smart charging system to exploit wind power produced at night to charge electric vehicles. In order to store electricity generated at night, windmill operators need to install sodium-sulfur battery systems, which are as costly as power generators.

Energy Harvesting for Wearable Technology Steps Up

Cars That Think

And today, technology is maturing to the point that meaningful amounts of these energy giveaways can be harvested to liberate wearables from ever needing a battery. Through this process the biofuels generated enough electricity to power both the e-skin’s sensors and data transmission, continuously charging a capacitor from 1.5

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. V and charges at 4.2-4.4 A = lithium or sodium (Li or Na), M represents a metal and 1 ≤ n < z.
