Fuel of a future: Research trickery in Dresden produces initial collection of Audi e-diesel

Posted on 21. Apr, 2015 by in Volkswagen Canada

Minister of Research, Prof. Dr. Johanna Wanka, and Reiner Mangold, Head of Sustainable Product Development during AUDI AG, refueled a Minister’s central automobile - a Audi A8 3.0 TDI purify diesel quattro - with a initial 5 liters of Audi e-diesel. Audi has taken another large step in a growth of new, CO2 neutral fuels: A commander plant in Dresden has started prolongation of a fake fuel Audi e diesel.

After a commissioning proviso of usually 4 months, a investigate trickery in Dresden started producing a initial batches of high‑quality diesel fuel a few days ago. To denote a bearing for bland use, Federal Minister of Education and Research Prof. Dr. Johanna Wanka put a initial 5 liters into her central car, an Audi A8 3.0 TDI purify diesel quattro*, this Tuesday. “This fake diesel, done regulating CO2, is a outrageous success for a sustainability research. If we can make widespread use of CO2 as a tender material, we will make a essential grant to meridian insurance and a fit use of resources, and put a fundamentals of a “green economy” in place,” announced Wanka.

The Dresden appetite record house sunfire is Audi’s plan partner and a plant operator. It operates according to a power‑to‑liquid (PtL) element and uses immature energy to furnish a glass fuel. The usually tender materials indispensable are H2O and CO dioxide. The CO2 used is now granted by a biogas facility. In addition, primarily a apportionment of a CO2 indispensable is extracted from a ambient atmosphere by means of approach atmosphere capturing, a record of Audi’s Zurich‑based partner Climeworks.

Reiner Mangold, Head of Sustainable Product Development during Audi, sees Audi e‑diesel and Audi e‑fuels in ubiquitous as an critical member that complements electric mobility: “In building Audi e-diesel we are compelling another fuel formed on CO2 that will concede long‑distance mobility with probably no impact on a climate. Using CO2 as a tender element represents an event not usually for a automotive attention in Germany, though also to send a element to other sectors and countries.”

Production of Audi e‑diesel involves several steps: First, H2O exhilarated adult to form steam is damaged down into hydrogen and oxygen by means of high-temperature electrolysis. This process, involving a feverishness in additional of 800 degrees Celsius, is some-more fit than required techniques given of feverishness recovery, for example. Another special underline of high-temperature electrolysis is that it can be used dynamically, to stabilise a grid when prolongation of immature energy peaks.

In dual serve steps, a hydrogen reacts with a CO2 in singularity reactors, again underneath vigour and during high temperature. The greeting product is a glass done from long‑chain hydrocarbon compounds, famous as blue crude. The potency of a altogether routine – from renewable energy to glass hydrocarbon – is really high during around 70 percent. Similarly to a hoary wanton oil, blue wanton can be polished to furnish a finish product Audi e‑diesel. This fake fuel is giveaway from sulfur and savoury hydrocarbons, and a high cetane series means it is straightforwardly ignitable. As lab tests conducted during Audi have shown, it is suitable for admixing with hoary diesel or, prospectively, for use as a fuel in a possess right.

The Federal Ministry of Education and Research is ancillary a sunfire project, that started in May 2012. Construction work on a trickery in Dresden‑Reick kicked off in Jul 2013 and a plant was consecrated on Nov 14, 2014. The plant is set to furnish over 3,000 liters (792.5 US gal) of Audi e‑diesel over a entrance months. Audi is sunfire’s disdainful partner in a automotive sector.

Over and above a partnership with sunfire, Audi has been active in a growth of CO2‑neutral fuels – Audi e‑fuels – given 2009. The Audi e‑gas plant in Werlte, Lower Saxony, already produces Audi e‑gas (synthetic methane) in a allied manner; drivers of a Audi A3 Sportback g‑tron* can fill adult on it regulating a special fuel card. Audi is also conducting corner investigate into a fake make of Audi e‑gasoline with Global Bioenergies, of France. In a serve project, Audi has assimilated army with a U.S. association Joule, that uses microorganisms to furnish a fake fuels Audi e‑diesel and Audi e‑ethanol.

Fuel expenditure of a models named above:

Audi A8:

Combined fuel expenditure in l/100 km: 5.9 (39.9 US mpg)**;

Combined CO2 emissions in g/km: 155 (249.4 g/mi)**

Audi A3 Sportback g-tron:

CNG expenditure in kg/100 kilometers: 3.3 – 3.2 (71.3 – 73.5 US mpg)**;

Combined fuel expenditure in l/100 km: 5.2 – 5.0 (45.2 – 47.0 US mpg)**;

Combined CO2 emissions in g/km (CNG): 92 – 88 (148.1 – 141.6 g/mi)**;

Combined CO2 emissions in g/km (gasoline): 120 – 115 (193.1 – 185.1 g/mi)**

**The fuel expenditure and a CO2 emissions of a car change due to a choice of wheels and tires. They not usually count on a fit function of a fuel by a vehicle, though are also shabby by pushing function and other non-technical factors.
