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

Green Car Congress

developed a halogen conversion–intercalation chemistry in graphite that produces composite electrodes with a capacity of 243 mAh g -1 (for the total weight of the electrode) at an average potential of 4.2 Proposed conversion–intercalation chemistry. A team of researchers led by a group from the University of Maryland has. Yang et al.

ICCT study compares leading global driving cycles and provides usable conversion factors for CO2 emissions

Green Car Congress

The result is a set of usable conversion factors for distance-based CO 2 emissions among the different driving cycles. The direct comparison of CO 2 or FC standards’ stringencies from different regions not only depends on the different driving cycles applied but also on the technical characteristics of the regional vehicle fleets.

New catalyst improves conversion of CO2 to syngas

Green Car Congress

In comparison with other two-dimensional materials such as graphene, there is no need to play with the chemistry of molybdenum disulfide, or insert any host materials to get catalytic activity, noted Bijandra Kumar, UIC post-doctoral fellow and co-first author of the paper. Carbon Capture and Conversion (CCC) Catalysts Fuels'

USDA provides $91M loan guarantee to Cool Planet for biogasoline blendstock plant; biomass pyrolysis and catalytic conversion

Green Car Congress

Gas chromatography comparison of Conoco fuel and a Conoco-CoolPlanet blend. Cool Planet has devised a biomass-to-liquids thermochemical conversion process that simultaneously produces liquid fuels and sequesterable biochar useful as a soil amendment. One of the catalytic conversion processes creates the high-octane gasoline blendstock.

Remy to Supply HVH250 Electric Motors to Advanced Mechanical Products for EV Conversions

Green Car Congress

AMP will use the Remy HVH250 electric motors in their custom electric vehicle conversions. The first two vehicles available for AMP conversions are the GM Saturn Sky and the GM Pontiac Solstice. By comparison, a full hybrid application yielded only a 5 °C difference between the two motor technologies over the same drive cycle.

VW Commercial Vehicles unveils e-BULLI; electric T1

Green Car Congress

VWCV partner eClassics is planning to offer T1 conversions and T1 complete vehicles in the style of the new e-BULLI. As the basis for the future e-BULLI the team chose a T1 Samba Bus produced in Hannover in 1966, which prior to its conversion spent half a century on the roads of California.
