Audi Begins Testing Engines Burning Fossil Free e-gasoline Bio-Fuel

Officially called e-fuel, the new substance will be made available in both e-gasoline and e-diesel versions sometimes in the distant future. The fuel is, in fact, a liquid isooctane produced from biomass in a two-step process.

The fuel is manufactured by combining gaseous isobutene with hydrogen. What comes out at the other end of the ensuing chemical reaction is a fuel that is, says Audi, free of sulfur and benzene. Having created enough for a test run, Audi engineers are currently testing the solution to check for combustion and emission performances.

The little thing that might turn the fate of the entire planet around is that, according to the Germans, sufficient research might make it possible to produce e-gasoline pretty much out of thin air, using only CO2 and hydrogen as source materials.

If the total environmental impact is less than conventional fuel, without detrimental effects to vehicles or owners, then cool.

I'm more optimistic about new ICE engine technologies, like Mazda's Skyactiv 2 (not in production yet), which alleges to deliver significantly lower emissions, significantly better fuel economy, and on regular gas. A great interim step while ICE is still the major propulsion system by far.

Quite true, but 99% of emissions are carbon dioxide an inert gas that all mammals exhale and plants ingest and create oxygen. Circle of life and all that. :)

That looks like Walter and Jesse's meth lab.
