I believe that as you say, converting the hydrogen obtained by electrolysis or photolysis into hydrocarbons via syngas is the most likely future solution for all energy storage problems where batteries are inappropriate.

Even if the energy efficiency of a storage cycle is lower than when using directly the hydrogen, the savings due to easier handling and storage are huge.

Moreover, that path will allow the reuse of all the existing infrastructure for hydrocarbons, whose replacement would require a very long time and very high costs.

H2 can be transported over natural gas pipelines. At least as high as 15% hydrogen / 85% Nat Gas.

Maybe that's not enough for the long term, but that mix/ratio should be sufficient to bootstrap the fledgling H2 industry.

If Syngas / synthetic diesel becomes more efficient in the future, we switch to that. I'm not against experimentation or tests.
