Elemental, My Dear: Audi’s E-Fuels Project Creates Diesel from Air, Water, and Electricity

Submitted by on November 21, 2014 – 5:46 pmNo Comment

by Andrew Hard (Digital Trends)  … Now Audi has announced the development of “e-diesel,” a CO2-neutral fuel made from sustainable raw materials like air, water, and electricity.

Like e-gas, e-diesel is created by combining hydrogen and CO2. Using a method called air capturing — a technology developed by Swiss company Climeworks — Audi’s technicians are able to gather carbon dioxide from the ambient atmosphere and contain it.

Once the CO2 is stowed, an electrolysis unit (powered by green electricity, of course) separates the hydrogen and oxygen molecules from water. The separated hydrogen mingles with CO2 in a heated and compressed chamber, and an energetic liquid called Blue Crude is born.

Blue Crude is nearly 80-percent convertible to synthetic diesel and can mix in any ratio with fossil fuel. It is also free of aromatics like sulfur, and because of its high cetane number, it’s very ignitable.  READ MORE
