1. Green H2 production needs to happen so that we get our fertilizers off of fossil fuels. The "greenification" of H2 / Ammonia / Fertilizer is one of the most important tasks of the near future, regardless of the energy / fuel issue.
2. Once we've stockpiled large amounts of H2, and created H2 pipelines to support the Fertilizer industry, we will gain the opportunity to use that H2 as transportation as well.
3. H2 to Syngas to Kerosene (or other hydrocarbons) are additional hits to efficiency. Electricity to H2 to electricity is some 40% efficient. But electricity to H2 to Syngas to Kerosene to ICE engine is like 1% efficient at best.
Maybe in the future, the H2 + CO2 Syngas -> Hydrocarbon chemistries can be made more efficient? But its not looking good for modern technology.

"Green" energy is going to be harder than just slurping up pre-made hydrocarbons in the ground. But we've got like, climate-change issues, pollution, and other such issues we're trying to deal with?
Diesel does work, and trains are rather efficient. But still, they're a good use case (large enough for H2 tanks), that H2 is likely a good fit. Might as well cut out the carbon emissions where it is easiest.
It probably will be easier to convert trains to H2 Fuel cells rather than Cars to EV / Li-ion.
