German supermarket chain EDEKA to convert its 700-vehicle fleet to low CO2 by 2025 with IVECO S-WAY LNG trucks

Green Car Congress

IVECO, the commercial vehicles brand of Iveco Group, will support EDEKA Minden-Hannover—one of the leading food retailers in Germany—in converting the entire 700-vehicle company fleet from diesel to BioLiquified Natural Gas (bio-LNG) propulsion by 2025. The switch to bio-LNG is a key lever in reducing our CO 2 footprint.

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. These elevators use equipment very similar to that used in the Brayton cycle test loop, called a permanent magnet rotor, to convert this energy, Fleming said.

Project HyTime demonstrates potential for major CO2 savings from hydrogen dual fuel

Green Car Congress

With between 20-45% of the diesel fuel being displaced by green hydrogen on the various vehicles, the HyTIME project concluded that with the appropriate hydrogen infrastructure, fleet wide roll-out could provide a huge and timely step change in overall fleet emissions.

Audi in new e-fuels project: synthetic diesel from water, air-captured CO2 and green electricity; “Blue Crude”

Green Car Congress

Audi’s latest e-fuels project is participation in a a pilot plant project in Dresden that produces diesel fuel from water, CO 2 and green electricity. Nearly 80% of that can be converted into synthetic diesel. diesel—is free of sulfur and aromatics, and features a high cetane number. This fuel—Audi e?diesel—is

WUSTL researchers demonstrate solar-panel-powered microbial electrosynthesis to produce n-butanol from light, CO2 and power

Green Car Congress

The resulting biofuel, n -butanol, is a carbon-neutral fuel alternative that can be used in blends with diesel or gasoline. Here we have harnessed the power of microbes to convert carbon dioxide into value-added multi-carbon compounds in a usable biofuel. —Wei Bai. Ranaivoarisoa, T.O.,

ETH Zürich team developing light-duty natural gas-diesel hybrid electric powertrain; 43 g/km CO2

Green Car Congress

Consumption measurements of the dual-fuel natural gas-diesel engine as a function of speed and load. Researchers at ETH Zürich have developed a light-duty hybrid electric vehicle featuring a dual-fuel natural gas-diesel engine. The ignition delay is mainly dependent on the chemical reaction kinetics of the diesel fuel.

EPFL team develops on-board system to capture CO2 from trucks; reducing emissions by 90%

Green Car Congress

That liquid is stored in a tank and can then be converted back into conventional fuel at the service stations using renewable electricity. Simple heat and mass flows for CO 2 capture from diesel engine exhaust: exhaust cooling, TSA cycle, product CO 2 compression, and liquefaction. Sharma and Maréchal.
