I am curious about the costs of this fuel. At the moment, electrification of traffic is cheaper and easier in most sectors and synthetic fuels are prohibitively expensive. Also, CO₂ emissions from burning fuel is not the only problem with our current traffic system, congestion, particulate matter and noise are huge issues, too.
We need to reduce individual motorised traffic (too many (and too big) cars with only the driver in it), improve and expand public transportation, walkability of cities etc.
But for sectors where these measures and transformations are not feasable or even possible (like air and ocean travel and cargo), alternatives like synthetic, emission free fuels are badly needed.

Maybe it’s a local thing, but here in Germany, the liberal party (FDP, neoliberals mostly) and others who do not want to make the adjustments necessary to limit climate change are pushing synthetic fuels (“E-Fuels”) and use them as an excuse to block any actualy effective measures.
Again, there are uses for such fuels, but they are very limited.
