New process for producing a fake fuel Audi e gas

Posted on 01. Mar, 2016 by in Audi Canada

Audi e gas is generally constructed in dual pivotal routine stairs – electrolysis and methanation. In a initial step, renewably generated electricity is used to separate H2O into hydrogen and oxygen. In a second step, a hydrogen is reacted with CO2 to furnish fake methane. In a Audi e gas plant in Werlte in a German state of Lower Saxony, this is finished regulating a chemical-catalytic routine underneath high vigour and high temperature. 

In a new Viessmann plant, methanation is now quite biological. Highly specialized microorganisms catch a hydrogen that is dissolved in glass and a CO dioxide by their dungeon walls. From these molecules they afterwards form a new proton methane. The routine is run underneath a assuage vigour of around 5 bar and during comparatively low temperatures. “We are essay a subsequent section of a Audi e gas story here,” pronounced Reiner Mangold, Head of Sustainable Product Development during AUDI AG, during a opening celebration. “Audi began to furnish a tolerable fuel in Werlte around dual years ago. Now we are also operative with a partner who immediately contributed this new process.” 

The commander plant sets another technical milestone: It is a initial power-to-gas plant to implement biological methanation opposite Germany. Its strength lies in a fact that it processes a CO dioxide contained in a tender biogas directly. Unlike chemical methanation, a CO2 does not need to be benefaction in high thoroughness or purified form. This opens adult new buying paths. Smaller sewage diagnosis and biogas plants, in that no biogas catharsis is performed, can now come into care as CO2 sources. 

Thanks to a new partnership, Audi will be means to supply a flourishing series of business with sustainably constructed e-gas in a future. Simultaneously, a code with a 4 rings is also fluctuating a choice of models with healthy gas drive. At a finish of 2016, sales of a new Audi A4 Avant g-tron* start in Europe. This is a second CNG indication from Audi after a Audi A3 Sportback g-tron*, that has been on a marketplace given a commencement of 2014. Customers can run both g-tron models on gasoline as good as on required healthy gas, biomethane or a sustainably constructed Audi e gas.

The Viessmann Group started adult a commander plant in stages commencement in Mar 2015. Like a Audi e gas plant in Werlte, it consumes tons of CO2 in a prolongation of a fake gas. Participating during a central opening of a plant in Allendorf along with Reiner Mangold, Head of Sustainable Product Development during Audi, were a Minister-President of Hesse, Volker Bouffier, and Prof. Martin Viessmann, CEO and partner of a Viessmann Group. 

Fuel expenditure of a models named above:

Audi A4 g-tron
This automobile is not nonetheless on sale. It has not nonetheless been homologated and is therefore not theme to a 1999/94/EG guideline.

Audi A3 Sportback g-tron
CNG expenditure in kg/100 kilometers: 3.6 – 3.3** (7.9 – 7.3 lb); 
Combined fuel expenditure in l/100 km: 5.5 – 5.1** (42.8 – 46.1 US mpg); 
Combined CO2 emissions in g/km (CNG): 98 – 89** (157.7 – 143.2 g/mi); 
Combined CO2 emissions in g/km (gasoline): 128 – 117** (206.0 – 188.3 g/mi)

**Fuel consumption, CO2 glimmer total and potency classes given in ranges count on a tires/wheels used.
