“Synthetic fuel is cleaner and there is no byproduct and when we start full production we expect a CO2 reduction of 85 percent," Walliser said.
He added it's important to consider the "wheel-to-well" emissions measurement when talking about EVs or E-Fuel
and said, "This will be the same level of CO2 produced in the manufacture and use of an electric vehicle."
As for how it works, a plant in southern Chile will implement a proprietary methanol-to-gasoline process provided under license by Exxon Mobil. Electrolyzers will split water into hydrogen and oxygen, and CO2 will be filtered out of the air and processed with the hydrogen to create synthetic methanol. Then the secretive methanol-to-gasoline work comes into play. Porsche's initial bet on the carbon-neutral gasoline involved a $24 million investment.
