Researchers propose new aluminum–sulfur battery with molten-salt electrolyte; low-cost, rechargeable, fire-resistant, recyclable

Green Car Congress

An international team of researchers led by Quanguan Pang at Peking University and Donald Sadoway at MIT reports a bidirectional, rapidly charging aluminum–chalcogen battery operating with a molten-salt electrolyte composed of NaCl–KCl–AlCl 3. A paper on the work is published in Nature. —Pang et al.

Convert Oil Wells to Solve the Solar Storage Problem

Cars That Think

Thermal energy storage is a known low-cost, low-risk approach for storing solar energy in the form of heat,” adds Codd. With the solar that you use every day of the year, you put that into high-temperature, short-term storage in the form of thermal oil or molten salt or any of the existing CSP thermal-storage technologies.”

Stanford team devises new bio-inspired strategy for using CO2 to produce multi-carbon compounds such as plastics and fuels

Green Car Congress

In the paper in Nature they showed that intermediate-temperature (200 to 350 ˚C) molten salts containing caesium or potassium cations enable carbonate ions (CO 3 2– ) to deprotonate very weakly acidic C–H bonds, generating carbon-centered nucleophiles that react with CO 2 to form carboxylates. —Banerjee et al.
