Audi stairs adult investigate into fake fuels

For some years now, Audi has been conducting investigate into climate-friendly, CO2-based fuels such as e-gas, e-gasoline or synthetically made e-diesel fuel. The association is now holding a subsequent step in e-diesel production. “At a plan in Laufenburg, interjection to a new record we are means to hoop a prolongation of e-diesel well in compress units, creation it some-more economical. The commander trickery offers range for zone coupling, in other difference mixing a appetite sectors power, feverishness and mobility, and creates it probable to store renewable energy,” explained Reiner Mangold, Head of Sustainable Product Development during AUDI AG.

Audi e-diesel has a intensity to make required explosion engines work roughly CO2-neutrally. To furnish it, a power-to-liquid plant translates over-abundance hydropower into fake fuel. A chemical element is applied: The immature appetite generated on site in a hydroelectric appetite hire produces hydrogen and oxygen from H2O by means of electrolysis. In a subsequent step a hydrogen reacts with CO2, regulating an innovative and really compress microprocess technology. The CO2 can be performed from a atmosphere or from biogenous rubbish gases and, as with all Audi e-fuels, is a usually source of carbon. Long-chain hydrocarbon compounds are formed. In a final routine step these are distant into a finish products Audi e-diesel and also waxes, that are put to use in other areas of industry.

There are skeleton to furnish a initial quantities of e-diesel in Laufenburg as early as subsequent year. Audi and a plan partner companies Ineratec and Energiedienst AG will contention a formulation focus for a trickery in a few weeks’ time. Construction work is to start in early 2018.

This is now Audi’s second partnership in a commander trickery that operates according to a power-to-liquid principle. Audi has already been operative together with a appetite record house sunfire in Dresden given 2014. There, sunfire is exploring a production of e-diesel regulating a above principle, though involving opposite technologies. The other Audi e-fuels projects embody a possess power-to-gas trickery in Werlte, north Germany, that creates Audi e-gas – in other difference fake methane – for a g-tron models A3, A4 and A5. The Ingolstadt carmaker is also researching a make of e-gasoline together with dilettante partners.

Fuel expenditure of a models named above:
A3 Sportback g-tron: CNG expenditure in kg/100 km: 3.5 – 3.3; total fuel expenditure in l/100 km: 5.4 – 5.1* (43.6 – 46.1 US mpg); total CO2 emissions in g/km (CNG): 96 – 89* (154.5 – 143.2 g/mi); total CO2 emissions in g/km (gasoline): 126 – 117* (202.8 – 188.3 g/mi)

A4 Avant g-tron: CNG expenditure in kg/100 km: 4.3 – 3.8*; total fuel consumption in l/100 km: 6.5 – 5.5* (36.2 – 42.8 US mpg); total CO2 emissions in g/km (CNG): 117 – 102* (188.3 – 164.2 g/mi); total CO2 emissions in g/km (gasoline): 147 – 126* (236.6 – 202.8 g/mi)

A5 Sportback g-tron: CNG expenditure in kg/100 km: 4.2 – 3.8; total fuel expenditure in l/100 km: 6.3 – 5.6* (37.3 – 42.0 US mpg); total CO2 emissions in g/km (CNG): 114 – 102* (183.5 – 164.2 g/mi); total CO2 emissions in g/km (gasoline): 143 – 126* (230.1 – 202.8 g/mi)

* Fuel expenditure and CO2 glimmer total given in ranges count on a tires/wheels used.
