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.

Researchers develop all-weather solar cell that generates power from rain as well as from sun

Green Car Congress

While many technical advances have made solar cells more efficient and affordable, a disadvantage remains in the fact that solar cells produce no power when it’s raining. c), d) The operational principle of the flexible solar cell under sunlight. Moreover, each droplet can yield voltage and output power of 152.6

The world’s only coal-to-nuclear reactor plant just broke ground in Wyoming

Baua Electric

Once it comes online, the Natrium demonstration plant in Kemmerer, Wyoming, will be a fully functioning commercial power plant. It’s being constructed near the retiring coal-fired Naughton power plant and is the world’s only coal-to-nuclear project under development. Get started here.

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

Example of a lithium-water rechargeable battery. 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 present sodium-sulfur battery operates above 300 °C.

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

Green Car Congress

This project furthers the company’s efforts as a leader in alternative power and a pioneer in green hydrogen technologies. —Amy Davis, Vice President and President of New Power at Cummins. When any type of electrolyzer is powered by renewable energy sources, such as wind, solar or hydro, it produces “green” hydrogen.

Caltech engineers devise new thermochemical cycle for water splitting for H2; recyclable, non-toxic, non-corrosive and at lower temperatures

Green Car Congress

The thermochemical production of hydrogen and oxygen from water via a series of chemical reactions is of interest because it directly converts thermal energy into stored chemical energy (hydrogen and oxygen), and thus can take advantage of excess heat given off by other processes. —Xu et al.
