Sandia team puts power into local grid with supercritical CO2 closed-loop Brayton-cycle turbine

Green Car Congress

Because so much energy is lost turning steam back into water in the Rankine cycle, at most a third of the power in the steam can be converted into electricity. In comparison, the Brayton cycle has a theoretical conversion efficiency upwards of 50%. The recuperator improves the overall efficiency of the system.

LBNL, Nissan researchers explore ethanol internal reforming in SOFCs for vehicle applications

Green Car Congress

The e-Bio Fuel Cell system featured an an SOFC stack and an on-board reformer to convert 100% ethanol or ethanol-blended water (55% water, 45% ethanol) to hydrogen. At the time, Nissan said it planned commercialization of the technology in 2020. Comparison of cell performance under ethanol internal reforming conditions.

New halogen conversion-intercalation chemistry enables high-energy density aqueous Li-ion battery

Green Car Congress

The use of ‘water-in-salt’ electrolytes has considerably expanded the electrochemical window of aqueous lithium-ion batteries to 3 to 4 volts, making it possible to couple high-voltage cathodes with low-potential graphite anodes. ) in graphite, a composite electrode containing equimolar lithium halide salts (LiBr) 0.5 (about 4.0 V) and Cl ?
