No. It really is a boondoggle for most proposed use cases, for a huge number of reasons. Storage and transport are your biggest issues. Production becomes less of an issue as renewables supply the energy to be stored as hydrogen, but that's a post-petro world already. Brine disposal is a big one as well (though I can think of profitable ways to make that work).

Hydrogen will always have a place, but in general it's a loser to other techs that check more boxes.

Absolutely not true! Hydrogen has way more capabilities to scale as innovation continues to bring prices down and safety increases. Just in 2021 alone, progress has been made in transport and storage. Saltwater to Hydrogen. Hydrocarbons to Hydrogen. Nuclear to Hydrogen. Ammonia as a carrier. Petro is a finite resource that is not clean and not scalable in the long term. Major players are starting to explore Hydrogen. So this is not a post petro movement. Not in the least. https://www.cnbc.com/2022/07/07/shell-to-build-europes-largest-renewable-hydrogen-plant.html........https://www.msn.com/en-us/autos/news/toyota-s-upcoming-hydrogen-powered-5-0-v-8-engine-has-the-potential-to-bury-evs/ar-AA15Q9mq?ocid=msedgdhp&pc=U531&cvid=7ddaeecdb9e647c8c57262dc64bf250b. Oh I can't imagine how many buggy whip manufacturers called the horseless carriage a boondoggle in the late 19th century.
