Storing energy as hydrogen involves a lot more than just a tank. Again, you obviously didn't bother reading up on this and you are guessing how hydrogen based energy systems work. You clearly don't.

BS, for liq. hydrogen you need to perfectly isolate it and that's it, the Adrianne rocket could achieve that with a 1.3mm think tank. And storing compressed hydrogen needs nothing more then a Gas tank like the one under your Grill. You even use compressed hydrogen for welding. Again, you know nothing and try to blind everyone with your highly secret knowledge. https://energies.airliquide.com/resources-planet-hydrogen/how-hydrogen-stored https://energies.airliquide.com/resources-planet-hydrogen/ho... >>For example, the tanks on the Ariane launcher, designed and manufactured by Air Liquide, contain the 28 tons of liquid hydrogen that will provide fuel to the central engine. These tanks are a genuine example of technological prowess: they weigh only 5.5 tons empty and their casing is not more than 1.3 mm thick.

  There is nothing "secret" about the challenges of turning energy into hydrogen and then back into heat or electricity. The challenges of each step along the energy chain are pretty well understood. You make the naive assumption that you temporarily storing hydrogen in a tank with 1.3mm thick walls that needs to last for, at most, a couple of days, has any relevance for permanent energy installations. If you are going to argue for an energy storage technology you have to consider what it would actually look like in practice. And since you only want to consider one part of the chain: I suggest you look into what it takes to safely store hydrogen in a vehicle and how this compares to your naive belief that hydrogen behaves like liquids that you have an intuitive understanding of. (Spoiler: you'd have a hard time convincing authorities to let you drive around traffic with a 1.3mm thick tank in the back of your car). Then again, I don't think you want to actually know anything about this. I think you only want to argue and you are annoyed that someone called you out.

    >Storing energy as hydrogen involves a lot more than just a tank. The 1.3mm example was to prove that it's technological possible to isolate liquid hydrogen with such a tank. In a car you don't use liq nitrogen[1]. You just shift the usage-surrounding to make your point, it's like saying "but using kerosene in a rocket needs some additional measures too", true. Exactly like using a toilet in space needs some additional measures too.

      You suggested that a tank used for ultra short-term storage of hydrogen was relevant in this context. I didn't. When you realized that your assumptions about hydrogen didn't hold you became unpleasant and childish.
