So I think two issues being conflated here. From a carbon footprint viewpoint, efuels offer advantages but from an air quality standpoint, there is little difference.Skyway wrote: ↑Wed Dec 06, 2023 12:25 pm This is what I read:
E-fuels are synthetic alternatives to fossil fuels that are made from hydrogen and CO2. They can be used in traditional combustion engines and distributed using networks that already exist.
The hydrogen needs to be produced using renewable or CO2-free energy and the CO2 has to come from capturing emissions in order for them to be considered carbon neutral.
E-fuels do still produce CO2 when they are burnt but those emissions are theoretically offset by the amount taken out of the atmosphere to produce the fuel
The vast majority of private car mileage takes place in the cities and surrounding suburbs so air pollution is the issue at hand here I think
