[Equipmentworld.com] While a future of electric charging stations dotting our highways inches closer to reality, Audi believes it may have created the “fuel of the future.”
Audi announced that the first batch of what it calls, “e-diesel” was manufactured in energy partner Sunfire’s Dresden, Germany, facility.
Water and carbon dioxide (CO2) are the only materials needed for producing the fuel, which was created after a commissioning phase of four months at the Dresden plant.
Through several steps of high-temperature and pressurized electrolysis and synthesizing, powered by renewable energy sources such as wind power, water and CO2 create what Audi and Sunfire call “blue crude.” This blue crude is then refined into Audi’s e-diesel.
The e-diesel, one of several Audi e-fuels in development, was used in German Minister of Education and Research Johanna Wanka’s official vehicle during the announcement.
“This synthetic diesel, made using CO2, is a huge success for our sustainability research,” Wanka said. “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.”
The main caveat is the price of the fuel. Sunfire says it costs between $4.25 and $6.42 per gallon.
However, the company’s feel that is within what most customers are willing to pay and Audi’s head of Sustainable Product Development Reiner Mangold added that the e-diesel has “virtually no impact on the climate.” Read More
