The electrification of the transport industry is making progress, at least as it concerns cars. However, for trucks, transport on water, and air transport little have changed. Here fossil fuel is still the primary workhorse. It is clear that storing energy in chemical bonds is convenient and economical, while there evidently remain issues with battery storage.
With high temperature molten salt reactors it is possible to generate synthetic fuel, in a sustainable fashion. John Bucknell presents the technology and simultaneously explains how such a system can improve the nuclear plant economics in this video.
