What do you think about the exceptionalist argument some people are making for hydrogen powered shipping?

Hydrogen might make sense for things like that! I have said before I can envision a future where it replaces diesel fuel for heavy-duty applications.

But it should not be used as a "better" alternative to electrochemical batteries because it simply isn't. It has significant tradeoffs.

According to someone working on e-fuels: hydrogen is a pain to store, so if you had abundant electricity and needed energy density (shipping, aviation) you'd probably synthesize a hydrocarbon instead

Does this make sense before we exceed 100% of grid demand with green energy and need to dump energy somewhere?

Electric cars made so much sense because we already had the distribution network in place, which you can't say for hydrogen.
