Instead of dumping more CO2 into the environment through its tailpipes, this German car company is recycling carbon dioxide to make green fuel.

Audi has successfully created a high-quality diesel fuel by combining water and C02 and started producing it earlier this week at their research facility in Dresden.

“If we can make widespread use of CO2 as a raw material, we will make a crucial contribution to climate protection and the efficient use of resources, and put the fundamentals of the “green economy” in place,” said Federal Minister of Education and Research Professor Dr. Johanna, who put the first five liters into her own Audi A8 3.0 yesterday.IKEA-solar-panels-photoby-hnnbz-CC

The Dresden energy technology corporation sunfire, Audi’s project partner, operates according to the power‑to‑liquid principle, using green power to produce a liquid fuel.

The science of it all breaks down like this: water is heated up to form steam, then broken down into hydrogen and oxygen by means of high-temperature electrolysis. Then, the hydrogen reacts with the CO2 in synthesis reactors, creating a reaction product made from long‑chain hydrocarbon compounds known as “blue crude.”

The CO2 used is currently supplied by a biogas facility. In addition, initially a portion of the CO2 needed is extracted from the ambient air by means of direct air capturing, a technology of Audi’s Zurich‑based partner Climeworks. The synthetic e-fuel is free from sulfur and aromatic hydrocarbons, and tests show it is suitable for mixing with fossil diesel or, prospectively, for use as a fuel in its own right.

“In developing Audi e-diesel we are promoting another fuel based on CO2 that will allow long‑distance mobility with virtually no impact on the climate,” said Reiner Mangold, Head of Sustainable Product Development at Audi. “Using CO2 as a raw material represents an opportunity not just for the automotive industry in Germany, but also to transfer the principle to other sectors and countries.”

  1. That’s great but you missed where the energy comes from. Fuel only stores energy. The energy comes from renewable sources, like solar or wind and is then converted into chemical energy by means of capturing CO2 from the air. That way, when you are burning the fuel you make use of the energy from solar or wind and release CO2 back to the environment making in CO2 neutral.

  2. This is really a cool method of getting pollution-less fuel alternative to the traditional diesel and petrol. But what I think is, there is always a trade-off in every story. And the same happens with this fuel generation from the mixing of carbon dioxide and water. Because this fuel generation process will be an expensive one. Whatever the matter is, there is always a solution to a new problem. And if you see, Audi has invented many groundbreaking technologies in the last few years. Apart from that, the engine of the vehicle is too complex due to many safety factor has been added to the new models. So every Audi owner should take proper and regular maintenance of their vehicle for a comfortable and safe journey always. I always rush to this trusted Audi repairing center in Highland Park if any issue happens with my vehicle and their service is higher than my expectation. Go to
