Oh god, can that damn hydrogen hype please die out. Hydrogen has an incredible amount of conversion loss both at generation and in recombination (each step only has about 40-60% efficiency rate) compared to way over 90% for lithium based batteries. Additionally, it's fiendishly difficult to safely transport it because it's highly explosive, and it will slowly leak out wherever it can.

The only place where hydrogen really has its uses is in synth-fuel applications (e.g. for airplanes) to shift these away from fossil-origin fuels, in processes where the heat of a burning flame is required and as raw material in chemical processes. Hydrogen generation capacity is incredibly scarce, we should reserve it for those processes that literally cannot use any alternative.

The reason why hydrogen hype will not die, and in fact will massively increase going forward, because those claims are simply wrong. It is nearly as efficiency as the lithium-based solution, while being drastically less dependent on rare resources.

People are starting to realize that most of the criticisms are literally just made-up bullshit from EV fanatics and were never true. The most notable example is the safety issue. Hydrogen is straight-up safer to deal with than lithium in a car. EV fans were just lying about this subject the entire time, and in fact you want a hydrogen car because it is outright a safer type of car.
