You can be as dishonest as you like, and I will call you on it each time.

I specifically cited ammonia and hydrogen as examples that may someday take over the storage load from the immediately viable alternatives I listed. (BTW, Ammonia is, in fact, not "just the storage mechanism for hydrogen", but is rather the heir apparent to bunker fuel for shipping. An industrial-scale electric ammonia plant is under construction in Norway. We will need just 1000 more of them to fuel all shipping.)

Underground compressed air does, in fact, get excellent insulation from the earth packed around it. Underwater compressed air does not, in fact, need insulation, because it may absorb heat from the water on its way out.

There is no need for air compression to become 1000x cheaper than at present. Air compression is mature technology. It only needs 1000x bigger capacity, achieved simply by scaling up well-understood technology. There is no need for air liquification to become 1000x cheaper. It is already mature, and efficient. It just needs to be scaled up, as we see occurring.

It might not be dishonesty or disingenuousness, it might be simple gullibility. The same person posted a link designed to fool gullible people and then proceeded to demonstrate that he had indeed been fooled by it:

https://www.energy.gov/ne/articles/5-fast-facts-about-spent-...

He claimed, with this link as backing, that all nuclear waste would fit in a small space, when in fact the link overlooks the vast majority of nuclear waste and considers only a minuscule though important subset, the spent fuel. We don’t even know if the source article is playing more tricks with words, but the mistake with gullibility here is already bad enough.

To give some credit where (malicious) credit is due, I do believe that the creators of the web page may have been striving for the goal of fooling such gullible people in exactly this way on exactly this matter. While technically honest, the site is dishonest and disingenuous in spirit, because it’s promoting such a misunderstanding, with a clear agenda and a not-so-innocent reason for doing so.
