“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.

And I bet the process requires an incredible amount of energy and the end product will carry an incredible price tag.

I saw this story as well. It was my first time hearing about it. Hopefully, it will come true.

The resulting gasoline is rated at 87 octanes by the Research Octane Number + Motor Octane Number/2 formula.
It is very clean, with no sulfur contamination and only 0.3 percent benzene.

would make more sense to build it in Texas?

With an eye to history,
it should be built in the little town of Louisiana, Missouri
where a Nazi synthetic fuel plant was re-erected and tested 1947 to 1952.
My father wrote his senior college thesis on this plant.

Didn't the German's have synthetic gasoline during WW2?

Yes.
After an Allied bombing mission to flatten the largest Nazi synthetic fuel complex suffered very heavy losses,
it was decided not to go back and bomb it again.

This has been called “The Greatest Allied Mistake of WW-II”

The war in Europe could have ended at least one year earlier, and perhaps two years earlier.

American and British bombing planners knew that the synthetic fuel plants produced gasoline, and considered them equal to refineries.

They did not know that the synthetic plants also produced explosives and synthetic rubber.

Instead of bombing ball bearing factories, railroad crossings, or airplane factories
what German sites should have been bombed?

Answer: bomb the sites the Germans were protecting most heavily.

Later in the war when the synthetic plants were bombed flat,
Albert Speer went to Hitler and told him: You have less than 90 days before we will not have supplies to fight with.
