New ways to produce Audi's synthetic e gas

Audi is finding new ways to product e gas, the synthetic and sustainably product vehicle fuel. The Viessmann Group is Audi's first partner in a new biological process to produce additional quantities of the fuel, with a pilot plant in Allendorf officially opened earlier this week. 

For the past two years, e gas has been produced by electrolysis and methanation at Audi's e gas plant in Werlte, in a process involving high pressure and high temperatures. The new Viessmann plant manages to follow the same procedure without high temperatures or high pressure. Methanation occurs purely biological, using specialised micro-organisms. 

The new plant is innovative in other ways as well, also opening up new procurement paths. Smaller sewage treatment and biogas plants, in which no biogas purification is performed, can now come into consideration as CO2 sources. 

Thanks to the new partnership, Audi will be able to supply a growing number of customers with sustainably produced e-gas. The brand will also extend its line-up of natural gas drive vehicles. By the end of this year, sales of the new Audi A4 Avant g-tron (pictured) will begin in Europe. This is Audi's second CNG model, after the A3 Sportback g-tron came on the market in 2014.
