Vanderbilt researchers find iron pyrite quantum dots boost performance of sodium-ion and Li-ion batteries

Green Car Congress

nm, average) of iron pyrite (FeS 2 ) nanoparticles are advantageous to sustain reversible conversion reactions in sodium ion and lithium ion batteries. In this work we explore the sodium and lithium conversion of ultrafine FeS 2 nanoparticles, with a tight size distribution centered around ∼4.5

PG&E, Calif. Energy Commission launch 4MW sodium-sulfur grid storage pilot in San Jose

Green Car Congress

Pacific Gas and Electric Company (PG&E) and the California Energy Commission today unveiled a utility-scale sodium-sulfur battery energy storage system ( earlier post ) pilot project to better balance power needs of the electric grid. The system has a 4 megawatt capacity, and can store more than six hours of energy.

RAL proposes new efficient and low-cost process to crack ammonia for hydrogen using sodium amide; transportation applications

Green Car Congress

RAL researchers are proposing a new process for the decomposition of ammonia to release hydrogen that involves the stoichiometric decomposition and formation of sodium amide from Na metal. To date, very few candidates show potential beyond that of the seminal work on titanium-doped sodium alanate. Credit: ACS, David et al.

Researchers develop rechargeable hybrid-seawater fuel cell; highly energy density, stable cycling

Green Car Congress

Researchers from Ulsan National Institute of Science and Technology (UNIST) in Korea and Karlsruher Institute of Technology in Germany have developed a novel energy conversion and storage system using seawater as a cathode. Similarly, sodium has recently attracted attention as a replacement for lithium in alkali-metal-air batteries.

CO2-neutral hydrogen storage with a bicarbonate/formate system

Green Car Congress

Metal hydride tanks store hydrogen in a relatively manageable volume but are very heavy and expensive, as well as operating only at high temperatures or far too slowly. The nontoxic aqueous solution of formate is easily stored and transported. to sodium formate in 96% yield at 70 °C in water/THF without additional CO 2.

Sigma-Aldrich and Ilika Technologies collaborate to scale-up and commercialize boron hydride hydrogen-storage materials

Green Car Congress

To be economically viable, the target weight percentage of hydrogen stored in such a material has been set at 6% by the US Department of Energy. weight% of hydrogen; the hydride materials being verified and scaled-up by Aldrich Materials Science can potentially store up to 10 weight% of hydrogen, reversibly, the company says.
