Audi creates new diesel fuel from carbon dioxide and water

What if you could power cars of the future with pollution created by the cars of the past? That's what German automaker Audi is hoping to achieve by creating a new synthetic fuel using renewable energy to turn water and carbon dioxide gas into a new kind of fuel they call "e-diesel." The new diesel is being produced at Audi's pilot plant Sunfire in Dresden, Germany. Only a few gallons were created, which the German Federal Minister of Education and Research Johanna Wanka put into her Audi A8 to prove the fuel's bonafides. The base fuel is known as "blue crude" and begins from a green source. Audi uses electricity from wind, water or solar power sources to separate hydrogen from oxygen in water. The hydrogen is then mixed with carbon dioxide which has been converted in carbon oxide. The blue crude is then further refined to create the e-diesel. The carbon dioxide is currently supplied by a biogas facilities, but some of that CO2 was captured from the air. "The engine runs quieter and fewer pollutants are being created," says Sunfire CTO Christian von Olshausen. The fuel can be combined with conventional diesel fuel, as biodiesel fuels already and would be competitively priced against regular diesel, according to Gizmag. Sunfire can produce about 42 gallons of e-diesel a day. That seems like barely a drop in the bucket in terms of Europe's energy use, but Audi is ready to commercialize the technology with plans to expand production with a bigger facility in the future.

1956 DKW Audi electric van beautifully restored

These days, electric vehicles that make commercial deliveries aren't entirely rare. UPS has a small fleet in California, and at least 5,000 Renault Kangoo Z.E. models are in use by France's national postal service. But the history of this concept is much older. In fact, one of the companies represented by Audi's four rings had an example about 60 years ago. Audi Tradition just completed a full restoration of this blue 1956 DKW Elektro-Wagen to add to the company's collection of historic vehicles. It's quite a rare find because only two are still known to exist. Audi estimates that DKW built about 100 of these electric vans between 1955 and 1962, and they were primarily sold to energy companies, public utilities and battery makers. To create the EV model, DKW took its normal Schnellaster delivery van and replaced the model's two-stroke engine with an electric drivetrain. The vans weren't exactly speedy, though. The motor produced about 6.7 horsepower and lead-acid batteries offered 200 amp hours of power running at 80 volts. It gave the Elektro-Wagen a claimed range of about 50 miles and a 25 mile-per-hour top speed. Following the restoration, Audi took van to the island of Wangerooge in the North Sea to show it off. The location is perfect, too, because vehicles with internal combustion engines are banned on the island.

Zwischen 1955 und 1962 produzierte die Auto Union GmbH in Ingolstadt DKW Schnellaster – etwa 100 davon als Elektro-Automobile, die das Unternehmen vor allem an Energieunternehmen, Stadtwerke oder Batteriehersteller verkaufte. Bei dem nun nach aufwandiger Restauration „heimgekehrten" Elektro-Schnellaster handelt es sich um ein besonderes Exponat: Der DKW fuhr auf der Nordseeinsel Wangerooge, wo Automobile mit Verbrennungsmotoren verboten sind. Normalerweise war der DKW Schnellaster mit einem Zweitaktmotor ausgestattet - der „Elektro-Wagen" hingegen mit einem funf Kilowatt (kw) leistenden Reihenschluss-Motor. Die seitlich in zwei Kasten gelagerten Bleibatterien hatten eine Nennspannung von 80 Volt und eine Kapazitat von 200 Amperestunden (AH).
