Audi updates A3 Sportback g-tron with increased tank volume for greater natural gas range

Green Car Congress

To enable the four-cylinder engine to run on these fuels, Audi engineers modified its cylinder head, turbocharging, fuel injection system and catalytic converter. Compared to gasoline, combustion of natural gas emits 25% less CO 2 due to the lowest carbon content of all hydrocarbons. The gasoline tank, which now holds nine liters (2.4

Hyundai introduces hydrogen fuel cell H350 light commercial van concept at IAA

Green Car Congress

Unlike a conventional electric vehicle, which requires a number of hours to recharge, the 175-liter hydrogen tank system can be filled in less than four minutes—similar to the time it takes to refill a tank of gasoline or diesel in a vehicle with a traditional internal combustion engine.

Audi to introduce natural gas A3 Sportback g-tron at year’s end; CO2-neutral e-gas

Green Car Congress

Key modifications relate to the cylinder head, turbocharging, injection system, and the catalytic converter. its performance figures are identical in CNG and gasoline modes. If the pressure in the tank drops below 10 bar, the engine management system automatically switches over to gasoline operation.

Global Bioenergies to collaborate with Audi on development of drop-in bio-isooctane

Green Car Congress

Light olefins are key chemical building blocks that can be converted into transportation fuels, polymers and various commodity chemicals. psi make it also attractive for bending into reformulated gasoline. As a 100% drop-in fuel, isooctane can be used in any blending ratio with all standard fuels for gasoline motors.

Global Bioenergies and LanzaTech to collaborate to assess the bioproduction of isobutene from carbon monoxide

Green Car Congress

Isobutene dimerization and hydrogenation to produce isooctane is used to increase the octane number of gasoline, and isobutene also reacts with alcohols such as ethanol to form ethyl tert-butyl ether (ETBE), a gasoline additive. Earlier post.). Jennifer Holmgren, LanzaTech CEO.

Soletair demo plant produces renewable hydrocarbon fuel from CO2 captured from the air

Green Car Congress

The produced dry hydrogen gas is stored into two 350 l composite cylinders. First, CO 2 is converted to CO using a reverse water gas shift reaction (rWGS) in which a gas mixture of CO, CO 2 , H 2 and H 2 O is balanced at 800 °C with the help of a precious metal catalyst. The Fischer-Tropsch production line has two major steps.
