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.

    There are some use-cases where hydrogen will be useful, but I don't think storage is one of them. Nor do I think vehicles are a particularly good use-case either, as compared to just iterating on battery technology.

    Acording to this paper/article, its better than technologies such as batteries, but the study isn't the most comprehensive and doesn't consider things like pump hydro.

    It's hard to assess the validity of those claims as the article doesn't bring any numbers and the paper itself is paywalled. As the fossil fuel industry is pushing hard towards wedging in hydrogen as a means of keeping themselves alive for a while longer, it's vital to be able to assess the actual claims, lest they are just planted there by the fossil fuel industry.

    "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.
