>For an electric vehicle, energy efficiency is estimated at 90%

Just because you draw the system boundaries with the inefficiencies outside, doesn't make them disappear.

Power generation, transmission, and distribution is on the order of 30%, before you take into account the inefficiencies of battery charging.



You have power generation, transmission and distribution also when you want to generate synfuel.


But the details may differ. If you can generate the synthetic fuel near the energy source, let's say a wind, farm you can shift the cost of transportation from one medium to another. That opens up possibilities to optimize on a network scale. In Germany, there is a pipeline network to transport and store natural gas to many many places. That transport is happening without trucks or ships driving around, I assume there are some pumps involved. But you don't have to move overhead mass.


>inefficiencies of battery charging

And the huge amount of energy for producing/recycle them.
