Assuming that a carbon neutral fuel for cars has to be used, what would be most practical and efficient? (Assumption: there is electricity from hydropower/nuclear or possibility to grow plants for biofuels)
1) Hydrogen from water hydrolysis?
(If I get it right, production is simple but the challenge starts with storage of liquid hydrogen)
2) Go next step and get methane from Sabatier reaction?

3) Go even a step further and get a liquid fuel through steam reforming?

4) Biomass gasification and get fuel a liquid fuel from it?
5) Or maybe just produce biofuels from crops / algae / whatever?
Which of those process would be worth using? With contemporary technology, but some serious adjustments in infrastructure are possible. I mean not only energy loses at production but also practicality of easy to transport and storage of fuel.
