Porsche says new fuel means that ICE won't go away.
"In a recent interview with Evo magazine, Porsche VP of Motorsport and GT cars, Dr. Frank Walliser, says that synthetic fuels, also called eFuels, can reduce the carbon dioxide emissions of existing ICE cars by as much as 85 percent. And, he says, when you account for the wheel-to-well impact of manufacturing the EV, it's a wash.
"Synthetic fuels are made by extracting hydrogen via renewable energy, and capturing it liquid form with carbon dioxide. Compared to pump fuel, eFuels emit fewer particulates and nitrogen oxide as well. That's because, as Walliser explains, they are composed of eight to 10 ingredients while the dead plants we mine contain 30 to 40, many of which are simply burned and emitted as pollution in the process."
