The usage of conventional energy sources to power the automobiles is getting antiquated. Petrol and diesel are quickly depleting and many organizations, including the auto manufacturers are working rapidly to find a credible and easy-to-use power source. While the electric motors are powering many cars, it still is difficult and expensive to use.
Setting their foot in the right direction, Audi, in the last November, unveiled their e-diesel research facility. And taking the achievement further, Audi has announced that the plant has successfully produced its first batch of e-diesel, the eco-friendly fuel. The first five litres of the e-diesel were used by Prof. Dr. Johanna Wanka, Germany's Federal Minister of Education and Research, into an A8, which happens to be her government car, to honor the event.
Prof. Dr. Johanna Wanka said “This synthetic diesel, made using CO2, is a huge success for our sustainability research." She went on to say "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.”
To give you a brief idea, the e-diesel is produced using the "power-to-liquid principle" that requires carbon dioxide, water and electricity as raw materials only. While the Audi didn't disclose the process due to obvious reasons, they have said that a direct air capture method developed by Climeweorks extracts the carbon dioxide from the air.
Also, an electrolysis unit in the plan is powered by the green electricity that splits the water into hydrogen and oxygen. This split hydrogen, then reacts with the carbon dioxide in a "two chemical processes conducted at 220 degrees Celsius (428 degrees Fahrenheit) and a pressure of 25 bar to produce an energetic liquid, made up of hydrocarbon compounds, which is called Blue Crude."
We say, it is a commendable job done by Audi. Only the future will tell how successful it will be as an alternate to conventional energy sources.
