Agenda

Why we are involved in renewable fuels

The principle of Audi e-fuels

The Audi e-gas project

The Audi e-diesel project


We make a simple but important mistake: We are focusing only on a limited part of reality

Fossil fuels (and biofuels) are limited in their availability: Audi’s e-fuels will help fill the gap

Agenda






Audi e-fuels are fuels made from renewable energies, water and CO2

Audi e-fuels:

• No fossil sources

• No biomass

• No competition with food production

• Use of CO2 as raw material

How do German customers use Audi e-gas?

► amount of fuel is registered via his Audi e-gas card

► Monthly account statement of amounts of e-gas purchased and reduction in CO2 emissions

► opt for a pre-paid contract for Audi e-gas

► Fill up on more than 600 German CNG stations

► Easy payment with e-gas credit card

► Monthly debiting of fuel price and e-gas climate fee

► Monthly reporting of saved CO2 by using e-gas

Mandatory for the environmental impact is the source of energy and not so much the power train concept

1 charging losses: 25%

2 charging losses: 25%; renewable: 2/3 wind, 1/3 e-gasoline; fossil: 2/3 electricity mix of EU-27, 1/3 gasoline 3 car manufacture today: 61 g CO2/km; reduction potential until 2030 to 56 g CO2/km renewable: 100% renewable; fossil: central steam methane reforming+ gaseous truck transportation 4 renewable: 100 % e-ethanol, fossil: 95 % gasoline, 5% ethanol
