Researchers convert atmospheric CO2 to carbon nanofibers and nanotubes for use as anodes in Li-ion and Na-ion batteries

Green Car Congress

Researchers from George Washington University and Vanderbilt University have demonstrated the conversion of atmospheric CO 2 into carbon nanofibers (CNFs) and carbon nanotubes (CNTs) for use as high-performance anodes in both lithium-ion and sodium-ion batteries. The conversion process builds upon the solar thermal electro-chemical process (STEP) introduced by GWU Professor Stuart Licht and his colleagues in 2009. Batteries Carbon Capture and Conversion (CCC

Chevron invests in Prussian Blue battery tech company Natron Energy; stationary storage for EV charging stations

Green Car Congress

Natron Energy , a developer of new battery cell technology based on Prussian Blue analogue electrodes and a sodium-ion electrolyte, has closed a strategic investment by Chevron Technology Ventures (CTV) to support the development of stationary energy storage systems for demand charge management at electric vehicle (EV) charging stations. Prussian blue dye, commonly used in blueprints, stores and releases energy in the form of sodium ions.

Zytek Shows Electric A-Class Demonstrator with Uprated 55kW E-Drive; Developed in 10 Weeks

Green Car Congress

Power is provided by two air-cooled sodium nickel chloride battery packs, integrated under the floor of the vehicle so they don’t compromise luggage space or vehicle stability. Low-volume vehicle build, typically for fleet trials, is conducted at Zytek, while for higher volumes the company supports assembly at the customer’s vehicle manufacturing facility, with the highly integrated design of E-Drive making it suited for integration alongside standard models.

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

Green Car Congress

The first thing postdoctoral scholar and lead author Bingjun Xu and graduate student Yashodhan Bhawe did was to perform a thermodynamic analysis demonstrating that it is unlikely, if not impossible, to split water with a two-step cycle where there is complete conversion between the oxidized and reduced forms at below 1,000 °C.

Haldor Topsøe ECO-Jet wins award; reducing soot, HC and heavy metal emissions from ships powered by bunker fuel

Green Car Congress

The ECO-Jet process also removes other harmful substances from the exhaust of engines using bunker fuel, for instance poisonous hydrocarbons and metals including vanadium, iron, nickel, silicon and sodium. Soot in the exhaust gas from the engine contains further inorganic ash that cannot combust and therefore will accumulate in the filter over time and build up the pressure drop.
