    and is a good way to store excess energy from solar and wind.

    Is it really that good of a storage method, though? The round-trip efficiency is quite bad when compared to other methods of storage.

      We’ll need it anyway to produce existing chemical materials sustainably. It may not be the best energy carrier nor most efficient, but it shines in specific applications. Vehicles are a promising example.

      “That good of a storage method” in terms of what, arbitrage? We should be producing hydrogen for the practical and environmental benefits of having emissions-free vehicle fuel (that avoids the problems of battery production and disposal), steel, and fertilizer.

        I don’t see any good reason why the merits of hydrogen for vehicle fuel would be any better than production and disposal of batteries. The other cases I agree that hydrogen will have a useful niche.
